We analyse subjective experiences of energy poverty to address the limitations of existing observable indicators as evidence for policy. We investigate the linkage between self-reported energy affordability and life satisfaction, health and economic inequality. A large-scale survey of 100,956 respondents across 37 nations shows that energy affordability concerns individuals in both developing and developed nations. Self-reported (perceived) values do not necessarily follow previous research and vary according to regional, economic, development and cultural factors. Contrasting this evidence with national-level data, such as healthy life expectancy and government spending on health and welfare, we identify associations between self-reported outcomes, income levels and national policy. Although national welfare spending can reduce the perceived economic gap, high income is not necessarily associated with better perceived satisfaction, health or economic outcomes. Enhancing energy access may lead to improved health outcomes in the most marginalized nations; however, lifestyle and cultural factors also play a role. Although the outcomes of less-developed nations can likely improve through development aid from more-developed nations, our results show that cultural and other factors underpin satisfaction in developing nations, which experience comparatively poorer life satisfaction. We identified that some nations had superior outcomes for health and life satisfaction despite lower income levels. This highlights the need for further research to uncover non-income-based factors that underlie life satisfaction and health, such as community connectedness or familial factors.

By focusing on a distributed energy system that has been widely diffused for efficient utilization of renewable energy generation in recent years, this paper investigates the relationship between productivity growth and information and communications technology capital in the energy sector. Information and communications technology is a key factor in operating distributed energy systems in a way that balances energy supply and demand in order to minimize energy loss and to enhance capacity utilization. The objective of this study is to clarify the determining factors that affect productivity growth, focusing on three different information and communications technologies: information technology capital, communication technology capital and software capital. Our estimation sample covers energy sectors in 14 countries from 2000 to 2014. The results show that information technology and software capital contribute to increasing material productivity and capital productivity in the energy sector, respectively. Meanwhile, communication technology capital negatively affects these two productivity indicators.

According to current global trends, there is little prospect of achieving either the IPCC’s target reduction of carbon emissions needed to hold temperature increases to both 1.5 and 2.0 degrees or the UN’s Sustainable Development Goal’s target of preserving 30% of the world’s biodiversity by 2030. Given the interrelationship between economic growth, rising carbon emissions and loss of biodiversity, conflicts are arising in simultaneously achieving the associated environmental goals. This study therefore proposes an innovative way to integrate programs which symbiotically meet interlocking threats of global degradation of natural capital and climate change. Using Australia as a case study, we demonstrate how a joint carbon and biodiversity credit/offset scheme could maximise the returns from both and avoid negative outcomes from their separation. We highlight studies which show that Australia has particular nature-based advantages which would allow the application of a joint carbon/biodiversity (JCB) credit/offset scheme to marginal agricultural lands even at low carbon offset prices. We further argue that such an integration of the two streams would deliver a number of advantages in terms of progressing environmental goals both in the Australian context and globally. It is further argued firstly that the integration of carbon and biodiversity schemes could do much to refocus attention on the global extent of biodiversity loss, which has generally been attracting a secondary priority to that of curbing of carbon emissions. Secondly, it is pointed out that such a linkage can provide a more attractive means for corporations which seek to voluntarily widen their environmental credentials.

The imperative for sustainable development demands innovative solutions to address the environmental impact of transportation, particularly in the context of climate change. This study explores the intersection of renewable energy and sustainability within the automotive industry by examining how restrictions on the sale of gasoline-powered vehicles affect patent filings related to automotive engine technologies. Our approach employs a factorial analysis to capture structural shifts in patent filings, utilizing the logarithmic mean Divisia index for index decomposition. We scrutinize patent trends from 1985 to 2019, with a focus on both non-green (internal combustion engine vehicles) and green technologies (battery electric, hybrid electric, and full cell vehicles), to assess the transition towards sustainable transportation. This study also scrutinizes the patenting activities of four major patent offices—China, Japan, the United States, and Germany—to unveil global trends and disparities in sustainable technology innovation. Our findings underscore how a nation’s green investment strategy is contingent upon its developmental stage, with intellectual property rights and R&D incentives playing pivotal roles in shaping R&D landscapes, especially in emerging economies with nascent intellectual property markets. This study also reveals varying strategies for developing green automotive engines across nations, indicating that the growth of green patents in developed countries is probably spurred by financial incentives and enhanced intellectual property rights to promote specific tech advancements. This research contributes to the discourse on sustainability by highlighting the critical role of policy in fostering green technology development and the importance of aligning patent strategies with environmental goals.

This study examines the financial implications of corporate environmental disclosure and performance across 34 countries, with a particular focus on industry-specific materiality following the SASB accounting metrics. A multilevel regression model was applied to a global sample spanning 2015 to 2022 to investigate the firm-level impacts while controlling for country-level effects to account for the heterogeneity in business environments. The analysis revealed a positive relationship between corporate environmental performance, both overall and materiality-based, and financial performance, including ROA and Tobin's Q. Notably, better environmental performance was significantly associated with decreased capital costs, particularly the cost of equity. However, materiality-based environmental scores exhibited weaker impacts, likely due to the limited data availability and inconsistent global integration of materiality concepts. The research findings indicate that investors tend to favor companies with accountable environmental performance over those that rely solely on disclosure. These findings provide valuable insights for investors and business practitioners, emphasizing the importance of considering environmental materiality in corporate reporting and operations.

This study uses factor decomposition analysis from the extended framework of Kaya’s identity to determine the factors influencing CO2 emissions in 138 countries worldwide from 2019–2022. The results revealed that CO2 emissions decreased due to economic stagnation caused by COVID-19 from 2019–2020. From 2020–2021, CO2 emissions increased due to economic recovery and increased dependence on fossil energy. However, the timing of recovery varies with income level. In low-income countries, economic recovery progressed more from 2021–2022 than from 2020–2021, which was the opposite of the situation in developed countries. In terms of technological factors, carbon intensity was a factor in increasing emissions in high-income countries during the recovery period, whereas fossil dependency and energy efficiency were factors in increasing emissions in upper-medium- and lower-medium-income countries, respectively. The results of the decoupling analysis indicate that lower-medium-income countries tend to exhibit undesirable decoupling. Furthermore, from an analysis of the transition of decoupling states, it is necessary to reduce the carbon intensity and fossil fuel dependency to achieve a desirable decoupling relationship between CO2 and economic development.

China’s carbon peaking and carbon neutrality goals present unique challenges and opportunities for industrial sectors. This study examines the impact of robotic technology on production efficiency in China’s industrial sectors from 2006 to 2016. Using data from the International Federation of Robotics (IFR) and employing the Tobit model, the analysis focuses on labor efficiency (LE), capital efficiency (CE), energy efficiency (EE), and total factor efficiency (TFE). The study also considers immediate and lagged effects of robotic adoption, and conducts robustness checks using two-stage least squares (2SLS) and fixed effects (FE) models. Additionally, the study explores the mediating effects of labor efficiency, capital efficiency, and energy efficiency on total factor efficiency. The results reveal that robotic technology significantly improves all dimensions of production efficiency, with the most notable enhancements observed in labor efficiency. The study identifies both immediate and lagged effects of robots on efficiencies, indicating a growing contribution over time, particularly in high-tech industries. Mediation effect tests show that improvements in labor efficiency account for approximately 65.16% of the total effect on total factor efficiency, while capital efficiency and energy efficiency contribute 12.98% and 12%, respectively. These results highlight the indispensable role of robotic technologies in steering China’s industrial sectors towards a more sustainable and efficient future, suggesting that policy frameworks and financial incentives should support robotic integration, particularly in high-tech industries.

Abstract <p>Scope 3 emissions, which encompass both direct emissions and induced emissions along upstream supply chains, have emerged as an important metric for evaluating corporate responsibility toward climate change. Scope 3 targets are being evaluated as a core element of decarbonization plans in many economically important jurisdictions. Yet robust Scope 3 reporting has been challenging due to varying system boundaries, diverging emission factors used for estimation, and the general absence of compliance audits. To overcome these limitations, and understand the efficacy of voluntary reporting, here we establish a consistent, independent estimate of Scope 3 emissions at the firm level using a new enterprise-level global supply chain database. We find that, collectively, company self-reported Scope 3 emissions may be underestimated by nearly 50%, or 0.75 Gt C, compared to our estimate using a harmonized approach.</p>

Many authors state that climate change is driven by increasing CO2 emissions worldwide. An understanding of the major driving forces affecting emissions over time in both developed and developing countries is important. Thus, in this study, structural break analysis is used to identify when the trends of environmental indicators—CO2 emissions and environmental efficiency (EE)—across countries worldwide change. Our findings revealed notable structural breaks occurring in countries in 1994, coinciding with ballooning fossil energy prices. Regarding CO2, 55 of 143 countries experienced a structural break. Furthermore, another wave of structural breaks emerged in 2014, corresponding to the implementation of CO2 emission reduction plans by certain nations. For CO2, 64 of 143 countries experienced a structural break. Upon detecting breakpoints and their trends, we utilized LMDI factor decomposition analysis to discern their driving factors, thereby elucidating the underlying dynamics. In Latin America and the Caribbean, most breakpoints were undesirable shifts, but recently, desirable shifts have increased in North America, Oceania, and Europe, which include many countries with high economic levels, improving energy-related factors. Sub-Saharan Africa can also be said to have undergone an undesirable shift regarding energy-related factors. This study clarifies the precise influences on the trend of CO2 emissions at the global level by identifying the point in time when there is a significant statistical, rather than a subjective, breakpoint.

An energy transition is in progress around the globe, notably led by an increase in the deployment of renewable energy and a shift toward less emissions-intense options, notably in the transportation sector. This research investigates the potential role that new transportation options, namely flying vehicles, may play toward progressing the energy transition. As flying vehicles are a relatively new technology yet to penetrate the market, it is also prudent to consider the ethical, legal, and social issues (ELSI) associated with their implementation, alongside the potential energy and environmental impacts. Through a review of ELSI and energy and environmental literature, we identify research gaps and identify how flying vehicles may impact upon the energy transition over time. Our research identifies several critical aspects of both ELSI and energy and environmental academia relevant to the future deployment of flying vehicles and describes a deployment timeline and the resultant societal outcomes. We find that flying vehicles could drive the energy transition and the hydrogen economy and that their widespread adoption could engender shared socio-environmental benefits. Our findings are relevant to transportation and environmental policymakers and identify critical considerations for the planned introduction of new, shared transportation options to the market, conducive to a sustainable energy transition.

Japanese companies are making rapid progress in addressing the Sustainable Development Goals (SDGs), and there is growing interest in the relationship between these goals and financial performance. Moreover, the promotion of the SDGs at the local level encourages opportunities for collaboration with companies. This study analyzed the relationship between the status of SDG efforts and the financial data, as well as social activity data of 533 Japanese manufacturing companies from 2016 to 2020. In terms of academic contribution, this study provides a unique case study in Japan, with consideration of the timing of the initiation of SDG efforts. The results showed that large companies and companies with high profitability tended to start working on the SDGs at an early stage. The results of a comparison of industries showed that the timing of the initiation of SDG initiatives is not affected by profitability in the food and electrical equipment sectors, where SDG efforts are already well underway. From the results of multiple regression analysis, it was found that large companies with high profitability that have implemented social activities tend to be early adopters of the SDGs. The results of this analysis suggest that it is important to design measures that are appropriate based on the size of the focal company and that social contribution activities should be incentivized to encourage companies to act on the SDGs.

The continued development of artificial intelligence (AI) has changed production methods but may also pose challenges related to energy consumption; in addition, the effectiveness of AI differs across industries. Thus, to develop efficient policies, it is necessary to discuss the effect of AI adoption on energy intensity and to identify industries that are more significantly affected. Using data on industrial robots installed in 16 Chinese industrial subsectors from 2006 to 2016, this paper investigates both the effect of AI on energy intensity and the channel through which this effect is transmitted. The empirical results show, first, that boosting applications of AI can significantly reduce energy intensity by both increasing output value and reducing energy consumption, especially for energy intensities at high quantiles. Second, compared with the impacts in capital-intensive sectors (e.g., basic metals, pharmaceuticals, and cosmetics), the negative impacts of AI on energy intensity in labor-intensive sectors (e.g., textiles and paper) and technology-intensive sectors (e.g., industrial machinery and transportation equipment) are more pronounced. Finally, the impact of AI on energy intensity is primarily achieved through its facilitation of technological progress; this accounts for 78.3% of the total effect. To reduce energy intensity, the Chinese government should effectively promote the development of AI and its use in industry, especially in labor-intensive and technology-intensive sectors.

Modern lifestyles demand a number of products derived from petroleum-based sources that eventually cause carbon emissions. The quantification of lifestyle and household consumption impacts upon carbon emissions from both the embodied CO₂ (EC) and materially retained carbon (MRC) viewpoints is critical to deriving amelioration policies and meeting emission reduction goals. This study, for the first time, details a methodology to estimate both EC and MRC for Japan, focusing on petrochemicals and woody products utilizing the time series input-output table, physical value tables and the national survey of family income and expenditure, leveraging time series input-output-based material flow analysis (IO-MFA), and structural decomposition analysis (SDA). Findings elucidated hot spots of deleterious consumption by age of householder and the critical factors which underpin them including intensity effects, pattern effects, and demographic shifts over time. Although demographic shifts associated with an aging, shrinking population in Japan decreased EC and MRC, the negative effect reduced in size over time during 1990-2005. Policy implications identify the potential to mitigate approximately 21% of required household emission reductions by 2030 through strategies including recycling initiatives and the recovery of carbon from products covered within current recycling laws and hot spot sectors which are not currently considered such as apparel.

Food security is a global challenge. With rising world population and demand for food being compounded by resource and arable land constraints, raising the efficiency of food production and use has become increasingly important. While much of the research on food security is focused on farm efficiency and productivity, most neglect post-harvest (PH) handling which is critical in determining the availability of food. In this study, we employ the network Data Envelopment Analysis (DEA) model to evaluate the PH efficiency of milling, using data from Kenya’s rice processing industry. The results show lower efficiency scores when using a network DEA model, which reflects its greater discriminatory power when compared to the standard DEA approach. The study also quantified sources of productive efficiency using a fractional regression model and identified storage space and distance to market as having an impact on drying efficiency; while experience, age of mill, servicing and energy type influenced milling efficiency. The results suggest that policy makers should focus on investing in drying technologies and storage facilities to improve drying efficiency. To improve milling efficiency, policy recommendations include enhancing millers’ access to better technologies, investing in reliable sources of energy and providing PH handling workshops to reduce PH losses.

With the Millennium Development Goal focusing on the eradication of poverty in developing countries expiring in 2015, the international focus is shifting toward sustainable development. The sustainability of the natural resources that are used as energy sources and in the production of goods is a global issue that is not specific to developing nations. We contribute to the need for quantitative targets for natural resources by calculating the shadow prices and production inefficiency levels of 32 mineral resources by using a stochastic frontier analysis and panel data from 1980 to 2010 in 162 countries. In addition, we provide estimated shadow prices and production inefficiency levels up to 2020 with various levels of production restrictions. The results show the following: (1) The shadow prices and production inefficiency levels of major metals are generally higher in Asian countries than in non-Asian countries; (2) there is an upward trend in the inefficiency levels in Asian countries, whereas the inefficiency levels remain rather stable in non-Asian countries; (3) production restrictions do not guarantee an increase in shadow prices, but the magnitude of the impact of such restrictions seems to be larger in Asian countries compared to non-Asian countries; (4) production restrictions do not seem to affect production inefficiency; thus, they may not be effective in reducing gaps in production inefficiency between Asian and non-Asian countries.

By exploiting data from the Toxic Release Inventory of the United States, we have established that the toxicological footprint (TF) increased by 3.3% (88.4 Mt) between 1998 and 1999 and decreased by 39% (1088.5 Mt) between 1999 and 2013. From 1999 to 2006, the decreasing TF was driven by improvements in emissions intensity (i.e. gains in production efficiency) through toxic chemical management options: cleaner production; end of pipe treatment; transfer for further waste management; and production scale. In particular, the mining sector reduced its TF through outsourcing processes. Between 2006 and 2009, decreasing TF was due to decrease in consumption volume triggered by economic recession. Since 2009, the economic recovery increased TF, overwhelming the influence of improved emissions intensity through population growth, consumption and production structures. Accordingly, attaining a less-toxic economy and environment will be influenced by a combination of gains in production efficiency through improvement in emissions mitigation technologies and changes in consumption patterns. Overall, the current analysis highlights the structural dynamics of toxic chemical release and would inform future formulation of effective mitigation standards and management protocols towards the detoxification of the environment.

Rapid urbanization has caused significant problems, and sustainable city design can play an important role in solving these problems under limited budgets and resources. Previous studies have proposed city evaluation indicators that can suggest appropriate urban designs. However, these indicators do not clearly consider economic theory, which is crucial for understanding accumulation of urban capital stock by the flows from daily urban activities. This study proposes a research framework based on economic theory for evaluating urban sustainability; this framework uses the inclusive wealth index (IWI) concept to examine inclusive urban capital stock. It examines the advantages of using the IWI as a city evaluation indicator along with data envelopment analysis and a decomposition analysis framework. We use data for 20 Japanese ordinance‐designated cities for an empirical study to demonstrate a proposed approach for evaluating inclusive urban capital. The developed research application evaluates each city's relative superiority in terms of capital accumulation and identifies those factors determining changes in capital flows via changes in efficiency, priority, and scale. The combination of these results can be helpful to decision makers seeking to increase urban capital by considering reference city information and relative superiority.

This study examined the impact of the financial crisis on the environmental and technical efficiencies of the Japanese manufacturing industry. Overall, we found that while the crisis had a negative impact on technical efficiency, it did not affect environmental efficiency—the only exception was the transportation equipment sector which improved its environmental efficiency following the crisis. Additionally, we found that capital intensity does not necessarily affect environmental efficiency. We discuss the implications of these findings and provide directions for future research.

To explain why and how corporate environmental management is beneficial, it is important to provide incentives to private companies to encourage such environmental activities. This study proposes a new corporate financial and environmental dataset called the world resource table (WRT), which uses open data sources published by the Japanese government. Environmental data include Greenhouse gas emissions and toxic chemical release data. With more than 1000 annual samples, the WRT will allow empirical analyses that use productivity measures and econometric approaches. WRT will also include corporate patent data, with linkages to analytical software packages such as GAMS and R.

This study analyzed the relationship between economic growth and emissions of eight environmental air pollutants (carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), nitrogen oxide (NOx), sulfur oxide (SOx), carbon monoxide (CO), non-methane volatile organic compound (NMVOC), and ammonia (NH₃)) in 39 countries from 1995 to 2009. We tested an environmental Kuznets curve (EKC) hypothesis for 16 individual industry sectors and for the total industrial sector. The results clarified that at least ten individual industries do not have an EKC relationship in eight air pollutants even though this relationship was observed in the country and total industrial sector level data. We found that the key industries that dictated the EKC relationship in the country and the total industrial sector existed in CO₂, N₂O, CO, and NMVOC emissions. Finally, the EKC turning point and the relationship between economic development and trends of air pollutant emissions differ among industries according to the pollution substances. These results suggest inducing new environmental policy design such as the sectoral crediting mechanism, which focuses on the industrial characteristics of emissions.

This chapter focuses on environmental management, corporations’ approaches to pollutant emission reduction, and the introduction of incentives for corporations to reduce pollutant emissions. It also discusses the effectiveness of models of these approaches, the burden of expense, and the efficiency of these approaches. In particular, the emphasis is on pollution abatement measures in the production process, with detailed explanations of the features and differences between end-of-pipe type emission reduction measurements and cleaner production type emission reduction measurements. In addition, factor analysis models that use numerical data to calculate the amount of (and changes in) pollutant emissions are introduced.

Environmental pollution and human health problems are becoming serious issues in China. This research focuses on regional differences in productive inefficiencies and attempts to clarify the determinants of inefficiency, accounting economic, environmental and health-related factors. Our dataset includes information of 29 areas in China from 2003 to 2009. We find that after accounting for environmental pollution and health impacts, the productive inefficiency of the examined areas reduced; this result holds for both the national and provincial levels. Our results imply that government efforts to improve social welfare should emphasize increases in foreign direct investment and private medical expenditures. JEL codes: I15, O44, O47, R11.

This paper analyzes productivity with a directional distance function model by investigating convexity and non-convexity in the Chinese banking sector. Two primary findings are summarized. First, there is a distinct change in productivity between large versus small banks and public versus nationwide joint-stock banks; the economies of scale and public orientation of the Chinese economy affect the performance of nationwide joint-stock banks. Second, the number of banks that experience local versus global technological change is small, indicating that productivity changes are driven by national rather than regional dynamics, although minor regional dynamics exist in the data.

To mitigate the effects of climate change, countries worldwide are advancing technologies to reduce greenhouse gas emissions. This paper proposes and measures optimal production resource reallocation using data envelopment analysis. This research attempts to clarify the effect of optimal production resource reallocation on CO₂ emissions reduction, focusing on regional and industrial characteristics. We use finance, energy, and CO₂ emissions data from 13 industrial sectors in 39 countries from 1995 to 2009. The resulting emissions reduction potential is 2.54 Gt-CO₂ in the year 2009, with former communist countries having the largest potential to reduce CO₂ emissions in the manufacturing sectors. In particular, basic material industry including chemical and steel sectors has a lot of potential to reduce CO₂ emissions.

This study estimates the environmental efficiency of international listed firms in 10 worldwide sectors from 2007 to 2013 by applying an order-m method, a non-parametric approach based on free disposal hull with subsampling bootstrapping. Using a conventional output of gross profit and two conventional inputs of labor and capital, this study examines the order-m environmental efficiency accounting for the presence of each of 10 undesirable inputs/outputs and measures the shadow prices of each undesirable input and output. The results show that there is greater potential for the reduction of undesirable inputs rather than bad outputs. On average, total energy, electricity, or water usage has the potential to be reduced by 50%. The median shadow prices of undesirable inputs, however, are much higher than the surveyed representative market prices. Approximately 10% of the firms in the sample appear to be potential sellers or production reducers in terms of undesirable inputs/outputs, which implies that the price of each item at the current level has little impact on most of the firms. Moreover, this study shows that the environmental, social, and governance activities of a firm do not considerably affect environmental efficiency.

This study analyzes the total factor productivity of 1067 Japanese manufacturing firms. In production estimation, we employ the directional distance function and Luenberger productivity indicator. Research and development strategy survey data are used to analyze the determinant factors related to improvements in innovation and productivity. Our results indicate that increasing technology and knowledge through a ‘black box’ process is related to an increase in productivity. Furthermore, the protection and management of production knowledge and expertise is a valid method of increasing global technical change.

This paper analyzes how a firm’s management of greenhouse gas (GHG) emissions affects its economic performance. The theoretical model we derive from Cobb–Douglas production and inverse demand functions predict that in conducting GHG emissions management, a firm will enhance its economic performance because it promotes an increase in demand for its output and improves its productivity. The estimation results, using panel data on Japanese manufacturing firms during the period 2007–2008, support the view that a firm’s GHG emissions management enhances a firm’s economic performance through an increase in demand and improvement in productivity. However, the latter effect is conditional. Although a firm’s efforts to maintain lower GHG emissions improves productivity, efforts to reduce GHG emissions further does not always improve it, especially for energy-intensive firms. Because firms attempting to maintain lower GHG emissions are more likely to improve their productivity, there is a possibility that firms with high GHG emissions can also enhance economic performance by reducing their emissions in the long term, even if additional costs are incurred. In addition, better GHG emissions management increases the demand of environmentally conscious customers because a product’s life cycle GHG emissions in the upper stream of the supply chain influence those in the lower stream, and customers evaluate the suppliers’ GHG emissions management in terms of green supply-chain management.

The objective of this study is to examine technical efficiency and productivity growth in the Indian banking sector over the period from 2004 to 2011. We apply an innovative methodological approach introduced by Chen et al. (2011) and Barros et al. (2012), who use a weighted Russell directional distance model to measure technical inefficiency. We further modify and extend that model to measure TFP change with NPLs. We find that the inefficiency levels are significantly different among the three ownership structure of banks in India. Foreign banks have strong market position in India and they pull the production frontier in a more efficient direction. SPBs and domestic private banks show considerably higher inefficiency. We conclude that the restructuring policy applied in the late 1990s and early 2000s by the Indian government has not had a long-lasting effect.

This study examines the impact of incentives on commuters' travel behavior based upon a questionnaire survey conducted with respect to the Beijing Subway System. Overall, we find that offering incentives to commuters, particularly fast food restaurant-related services and reduced ticket fares, has a positive influence on avoiding the morning rush hour. Furthermore, by using an interaction analysis, we discover that a flexible work schedule has an impact on commuters' behavior and the efficiency of the subway system. Finally, we recommend two possible policies to maximize the utility of the subway system and to reduce congestion at the peak of morning service: (1) a set of incentives that includes free wireless internet service with a coupon for breakfast and a discount on ticket fares before the morning peak and (2) the introduction of a flexible work schedule.

This study analyzes the management of air pollutant substance in Chinese industrial sectors from 1998 to 2009. Decomposition analysis applying the logarithmic mean divisia index is used to analyze changes in emissions of air pollutants with a focus on the following five factors: coal pollution intensity (CPI), end-of-pipe treatment (EOP), the energy mix (EM), productive efficiency change (EFF), and production scale changes (PSC). Three pollutants are the main focus of this study: sulfur dioxide (SO₂), dust, and soot. The novelty of this paper is focusing on the impact of the elimination policy on air pollution management in China by type of industry using the scale merit effect for pollution abatement technology change. First, the increase in SO₂ emissions from Chinese industrial sectors because of the increase in the production scale is demonstrated. However, the EOP equipment that induced this change and improvements in energy efficiency has prevented an increase in SO₂ emissions that is commensurate with the increase in production. Second, soot emissions were successfully reduced and controlled in all industries except the steel industry between 1998 and 2009, even though the production scale expanded for these industries. This reduction was achieved through improvements in EOP technology and in energy efficiency. Dust emissions decreased by nearly 65% between 1998 and 2009 in the Chinese industrial sectors. This successful reduction in emissions was achieved by implementing EOP technology and pollution prevention activities during the production processes, especially in the cement industry. Finally, pollution prevention in the cement industry is shown to result from production technology development rather than scale merit.

This study elucidated the shadow price of greenhouse gas (GHG) emissions for 1,024 international companies worldwide that were surveyed from 15 industries in 37 major countries. Our results indicate that the shadow price of GHG at the firm level is much higher than indicated in previous studies. The higher shadow price was found in this study as a result of the use of Scope 3 GHG emissions data. The results of this research indicate that a firm would carry a high cost of GHG emissions if Scope 3 GHG emissions were the focus of the discussion of corporate social responsibility. In addition, such shadow prices were determined to differ substantially among countries, among sectors, and within sectors. Although a number of studies have calculated the shadow price of GHG emissions, these studies have employed country-level or industry-level data or a small sample of firm-level data in one country. This new data from a worldwide firm analysis of the shadow price of GHG emissions can play an important role in developing climate policy and promoting sustainable development.

This study analyzed the relationship between the CO₂ emissions of different industries and economic growth in OECD countries from 1970 to 2005. We tested an environmental Kuznets curve (EKC) hypothesis and found that total CO₂ emissions from nine industries show an N-shaped trend instead of an inverted U or monotonic increasing trend with increasing income. The EKC hypothesis for sector-level CO₂ emissions was supported in the (1) paper, pulp, and printing industry; (2) wood and wood products industry; and (3) construction industry. We also found that emissions from coal and oil increase with economic growth in the steel and construction industries. In addition, the non-metallic minerals, machinery, and transport equipment industries tend to have increased emissions from oil and electricity with economic growth. Finally, the EKC turning point and the relationship between GDP per capita and sectoral CO₂ emissions differ among industries according to the fuel type used. Therefore, environmental policies for CO₂ reduction must consider these differences in industrial characteristics.

This study examines the relationship between environmental performance and economic performance in Japanese manufacturing firms. The environmental performance indicators include CO₂ emissions and the aggregate toxic risk associated with chemical emissions relative to sales. Return on assets (ROA) is used as an indicator of economic performance. We demonstrate that there is a significant inverted U-shaped relationship between ROA and environmental performance calculated by aggregated toxic risk. We also find that the environmental performance increases ROA through both returns on sales and improved capital turnover. However, we observe a significant positive relationship between financial performance and environmental performance based on CO₂ emissions. These findings may provide evidence for the consequences of firms' environmental behavior and sustainable development.

Summary: This study analyzes toxic chemical substance management in three U.S. manufacturing sectors from 1991 to 2008. Decomposition analysis applying the logarithmic mean Divisia index is used to analyze changes in toxic chemical substance emissions by the following five factors: cleaner production, end-of-pipe treatment, transfer for further management, mixing of intermediate materials, and production scale. Based on our results, the chemical manufacturing sector reduced toxic chemical substance emissions mainly via end-of-pipe treatment. In the meantime, transfer for further management contributed to the reduction of toxic chemical substance emissions in the metal fabrication industry. This occurred because the environmental business market expanded in the 1990s, and the infrastructure for the recycling of metal and other wastes became more efficient. Cleaner production is the main contributor to toxic chemical reduction in the electrical product industry. This implies that the electrical product industry is successful in developing a more environmentally friendly product design and production process.

This study measures productive inefficiency within the context of multi-environmental pollution (eco-efficiency) in the Chinese industrial sector. The weighted Russell directional distance model is applied to measure eco-efficiency using production technology. The objective is to clarify how external factors affect eco-efficiency. The major findings are that both foreign direct investment and investment for pollution abatement improve eco-efficiency as measured by air pollutant substances. A levy system for wastewater discharge improves eco-efficiency as measured by wastewater pollutant substances. However, an air pollutant levy does not significantly affect eco-efficiency as measured by air pollutants.

In this paper, to clarify whether a firm's voluntary approach to environmental protection is beneficial for both the environment and business, we analyze whether a firm's voluntary implementation of an environmental management system (EMS) simultaneously reduces its environmental impacts and improves its productivity. Using data on Japanese manufacturing firms for 2002-2008, we find empirical support for the view that the implementation of an EMS simultaneously reduces environmental impacts and improves productivity, and that a reduction in environmental impacts also improves productivity. However, in the context of this relationship, the direct effect of implementing an EMS on productivity is conditional. If various other activities designed to improve productivity implemented in response to market discipline are also taken into account, the effect of implementing an EMS is hidden by the effects of these activities. This implies that voluntary environmental management activities are merely a minor component of these activities. Therefore, the relationship between the implementation of an EMS and productivity improvement is not strong, although implementing an EMS indirectly improves productivity by reducing environmental impacts.

Corporate social responsibility is imperative for manufacturing companies to achieve sustainable development. Under a strong environmental information disclosure system, polluting companies are disadvantaged in terms of market competitiveness, because they lack an environmentally friendly image. The objective of this study is to analyze productive inefficiency change in relation to toxic chemical substance emissions for the United States and Japan and their corresponding policies. We apply the weighted Russell directional distance model to measure companies productive inefficiency, which represents their production technology. The data encompass 330 US manufacturing firms observed from 1999 to 2007, and 466 Japanese manufacturing firms observed from 2001 to 2008. The article focuses on nine high-pollution industries (rubber and plastics; chemicals and allied products; paper and pulp; steel and non-ferrous metal; fabricated metal; industrial machinery; electrical products; transportation equipment; precision instruments) categorized into two industry groups: basic materials industries and processing and assembly industries. The results show that productive inefficiency decreased in all industrial sectors in the United States and Japan from 2001 to 2007. In particular, that of the electrical products industry decreased rapidly after 2002 for both countries, possibly because of the enforcement of strict environmental regulations for electrical products exported to European markets.

This paper analyzes whether the reduction of pollution emissions improves a firm's economic performance through the increase in sales to environmentally conscious customers and the cost reductions associated with the improvement in productivity. Because the selection of the control (end-of-pipe) or prevention (cleaner production) approach differently influences the effect through the improvement in productivity, this is also considered. Using panel data for Japanese manufacturing firms over the period 2002-2008, the findings indicate that firms that have reduced their pollution emissions can increase their economic performance through the increase in demand for their products and an improvement in productivity. However, the latter is conditional, and so the prevention approach is preferred.

This study analyzes Total Factor Productivity (TFP), which includes all categories of productivity. Our measure investigates productivity in the context of the provision and dissemination of environmental information policies. We investigated data on the emission of toxic chemical substances for the U.S. and Japanese manufacturing firms, including 386 firms for the period 1999-2007 and 466 firms for the period 2001-2008. The results show that productivity improved in all nine industrial sectors and that pollution levels were high in the U.S. and Japan from 2001 to 2007. In particular, the electronics industry improved rapidly after 2002 in both countries, which may be attributed to the enforcement of RoHS and the REACH directive in Europe. As a result of these stringent policies on toxic chemical emissions, the U.S. and Japanese firms, many of which export to the European market, have strong incentives to reduce their toxic chemical emissions.

Technological modernization is widely believed to contribute positively both to economic development and to environmental and resource conservation, through improvements in productivity and strengthening of business competitiveness. However, this may not always be true, particularly in the short term, as it requires substantial investments and may impose financial burdens on firms undertaking such investments. This study empirically examines the effects of technological modernization in China's iron and steel industry in the 1990s on conventional economic productivity (CEP) and environmentally sensitive productivities (ESPs). We employ a directional distance function that can handle multiple inputs and outputs to compute relative production efficiencies. We apply these models to the data covering 27 iron and steel firms in China between 1990 and 1999-a period when the Chinese iron and steel industry modernized rapidly. We find that ESPs have continuously improved, even in the period when the CEP declined.

This study explores empirical evidence for two hypotheses through a macro productivity analysis using the nonparametric directional distance function approach applied to the thermal power sector. The first hypothesis is that the marginal abatement cost has significantly declined in recent years mainly due to domestic flue gas desulfurization technology in China, which has become available at a reasonable cost. The second is the existence of a certain budget scale, which, with policy intervention, would have significant outcomes. These hypotheses are successfully addressed through the findings that the marginal abatement cost in 2006 had declined by half since 2003 and that the strategic allocation of 10 billion yuan for SO₂ emissions abatement would result in an additional 550,000 tonnes of SO₂ reductions.

China is an emerging and leading world economy. The pace of economic change has been tremendously rapid since the beginning of economic reforms. Despite the importance of the Environmental Kuznets Curve (EKC) and environmental problems in China, no previous study has tested the EKC in China because of the difficulty in obtaining data and the need to adjust the data. The focus of this paper is to test the EKC in China using province level data over the period 1992-2003. This study applies non-parametric techniques to estimate the relationship between income and the environmental quality of wastewater, air pollution and solid waste.

This article analyses the relationship among the environmental behavior of Japanese firms, external factors, and economic・environmental performance. Since 1990s, there are many efforts to investigate the relationship between economy and environment. But most of these researches did not explain causal relationship between economy and environment. In this paper, we analyzed the relationship based on the Resource-Based View framework of management. This approach can explain actions of firms and environmental results, emphasizing the process and organizational capabilities. The findings of analyses indicate that external factors such as government, community, and customers are not necessarily effective to enhance the positive action by firms to improve the environmental performance. Rather, it shows corporate strategy stimulates the organizational practices for environment and then leads to better environmental performance.

Toxic chemical management is vital to environmental protection and economic development in industrialized countries because it reduces the abatement costs associated with the use of toxic chemicals and minimizes the risk of accidental pollution. However, aspects related to toxic chemical emissions that are generated by the product supply chains that connect consumers to producers have not been widely studied. This talk introduces integrated decomposition analysis framework to clarify the main drivers of changes in the toxicity of production- and consumption-based chemical emissions. The results showed that toxic emissions from the US industrial sector decreased by 83% over the studied period because of pollution abatement efforts adopted by US industries. A variety of pollution abatement efforts were used by different industries, and cleaner production in the mining sector and the use of alternative materials in the manufacture of transportation equipment represented the most important efforts.

By focusing on a distributed energy system that has been widely diffused for efficient utilization of renewable energy generation in recent years, this paper investigates the relationship between productivity growth and information and communications technology capital in the energy sector. Information and communications technology is a key factor in operating distributed energy systems in a way that balances energy supply and demand in order to minimize energy loss and to enhance capacity utilization. The objective of this study is to clarify the determining factors that affect productivity growth, focusing on three different information and communications technologies: information technology capital, communication technology capital and software capital. Our estimation sample covers energy sectors in 14 countries from 2000 to 2014. The results show that information technology and software capital contribute to increasing material productivity and capital productivity in the energy sector, respectively. Meanwhile, communication technology capital negatively affects these two productivity indicators.
