| Summary/Abstract |
Based on the input-output model and the comparable price input-output tables, the current paper investigates the indirect carbon emissions from residential consumption in China in 1992-2005, and examines the impacts on the emissions using the structural decomposition method. The results demonstrate that the rise of the residential consumption level played a dominant role in the growth of residential indirect emissions. The persistent decline of the carbon emission intensity of industrial sectors presented a significant negative effect on the emissions. The change in the intermediate demand of industrial sectors resulted in an overall positive effect, except in the initial years. The increase in population prompted the indirect emissions to a certain extent; however, population size is no longer the main reason for the growth of the emissions. The change in the consumption structure showed a weak positive effect, demonstrating the importance for China to control and slow down the increase in the emissions while in the process of optimizing the residential consumption structure. The results imply that the means for restructuring the economy and improving efficiency, rather than for lowering the consumption scale, should be adopted by China to achieve the targets of energy conservation and emission reduction.

| Summary/Abstract |
As the capital of China, Beijing is regarded as a major metropolis in the world. Study of the variation in temporal CO2 emissions generated by the driving forces in Beijing can provide guidance for policy decisions on CO2 emissions mitigation in global metropolises. Based on input-output structural decomposition analysis (IO-SDA), we analysed the driving forces for the increment in CO2 emissions in Beijing from both production and final demand perspectives during 1997-2010. According to our results, the CO2 emission growth in Beijing is driven mainly by production structure change and population growth, partly offset by CO2 emission intensity reduction as well as the decline in per capita final demand volume during the study period. Final demand structure change has a limited effect on the change in the CO2 emissions in Beijing. From the final demand perspective, urban trades, urban residential consumption, government consumption and fixed capital formation are mainly responsible for the booming emissions. This study showed how the "top-down" IO-SDA methodology was implemented on a city scale. Policy implications from this study would be helpful for addressing CO2 emissions mitigation in global capital cities and metropolises.

| Summary/Abstract |
China proposed a CO2 mitigation target in 2020 to deal with anthropogenic global climate change. Chinese policy makers mainly focus on three factors comprising consumption structure changes, energy technology development, and new energy increments. In addition, sectoral CO2 reduction is increasingly concerned in the world. Thus, it is significant to investigate integrated impacts of three factors to China's CO2 mitigation target as well as to identify key economic sectors for achieving this target. In this study, energy demand and CO2 emission in 2020 are predicted. Five scenarios are generated to illustrate the contributions of three factors. In addition, twelve key economic sectors for reducing energy demand and CO2 emission are identified from both production and final demand perspectives. Under integrated impacts of three factors, China's CO2 intensity per unit gross domestic product in 2020 will decrease by about 43.9% in 2020 than 2005 level. In the short term, China's CO2 mitigation will be highly dependent on energy technology development. In the long term, it will mainly rely on reshaped consumption structure changes and new energy development. In addition, China's future policies should focus on 12 identified key economic sectors.

| Summary/Abstract |
In this study, we apply the inter-regional input-output model to explain the relationship between China's inter-regional spillover of CO2 emissions and domestic supply chains for 2002 and 2007. Based on this model, we propose alternative indicators such as the trade in CO2 emissions, CO2 emissions in trade and the regional trade balances of CO2 emissions. Our results do not only reveal the nature and significance of inter-regional environmental spillover within China's domestic regions but also demonstrate how CO2 emissions are created and distributed across regions via domestic and global production networks. Results show that a region's CO2 emissions depend on its intra-regional production technology, energy use efficiency, as well as its position and participation degree in domestic and global supply chains.

| Summary/Abstract |
We develop an input-output methodology to estimate how Chinese exports affected the country's total domestic value added (DVA) and employment in the years 2002 and 2007. For every US$1000 dollar of Chinese exports in 2007 (2002), DVA and employment are estimated to be US$591 (US$466) and 0.096 (0.242) person-year, respectively. To implement these estimations, we use hitherto unpublished Chinese government data to construct several completely new datasets, including an input-output table with separate input-output and employment-output coefficients for processing exports, non-processing exports, and output for domestic use. We hypothesize that, in comparison with the export sector, China's domestic sector would be relatively autarkic due to China's history of central planning. We expect that exports would generate less DVA and employment than output for domestic use. Processing exports, which are highly dependent on imported inputs, would similarly generate less DVA and employment than non-processing exports. Our findings support these expectations. For both 2002 and 2007, the DVA and employment effects of domestic final demand were higher than those of non-processing exports, which were in turn higher than those of processing exports. However, with the progress of economic reforms, we found that the total DVAs of exports and domestic final demand have converged from 2002 to 2007.

| Summary/Abstract |
Despite differences in their implementation, most carbon policies aim to have similar outcomes: effectively raising the price of carbon-intensive products relative to non-carbon-intensive products. While it is possible to predict the simple broad-scale economic impacts of raising the price of carbon-intensive products-the demand for non-carbon-intensive products will increase-understanding the economic and environmental impacts of carbon policies throughout the life cycle of both types of products is more difficult. Using the example of a carbon tax, this study proposes a methodology that integrates short-term policy-induced consumer demand changes into the input-output framework to analyze the environmental and economic repercussions of a policy. Environmental repercussions include the direct and the indirect impacts on emissions, materials flow in the economy, and the reliance on various ecosystem goods and services. The approach combines economic data with data about physical flow of fossil fuels between sectors, consumption of natural resources and emissions from each sector. It applies several input-output modeling equations sequentially and uses various levels of aggregation/disaggregation. It is illustrated with the data for the 2002 U.S. economy and physical flows. The framework provides insight into the short-term complex interactions between carbon price and its economic and environmental effects.

| Summary/Abstract |
To address the climate change issue, developed nations have considered introducing carbon pricing mechanisms in the form of a carbon tax or an emissions trading scheme (ETS). Despite the small number of programmes actually in operation, these mechanisms remain under active discussion in a number of countries, including Japan. Using an input-output model of the Japanese economy, this article analyses the effects of carbon pricing on Japan's industrial sector. We also examine the impact of a rebate programme of the type proposed for energy-intensive trade-exposed (EITE) industries in U.S. legislation, the Waxman-Markey Bill (H.R. 2454), and in the European Union's ETS. We find that a carbon pricing scheme would impose a disproportionate burden on a limited number of sectors - namely, pig iron, crude steel (converters), cement and other EITE industries. Out of 401 industries, 23 would be eligible for rebates according to the Waxman-Markey-type programme, whereas 122 industries would be eligible for rebates according to the E.U.-type programme, if adopted in Japan. Overall, despite the differences in coverage, we find that the Waxman-Markey and E.U. rebate programmes have roughly similar impacts in reducing the average burden on EITE industries.

| Summary/Abstract |
Global warming mitigation has recently become a priority worldwide. A large body of literature dealing with energy related problems has focused on reducing greenhouse gases emissions at an engineering scale. In contrast, the minimization of climate change at a wider macroeconomic level has so far received much less attention. We investigate here how to mitigate global warming by performing changes in an economy. To this end, we make use of a systematic tool that combines three methods: linear programming, environmentally extended input output models, and life cycle assessment principles. The problem of identifying key economic sectors that contribute significantly to global warming is posed in mathematical terms as a bi-criteria linear program that seeks to optimize simultaneously the total economic output and the total life cycle CO2 emissions. We have applied this approach to the European Union economy, finding that significant reductions in global warming potential can be attained by regulating specific economic sectors. Our tool is intended to aid policy makers in the design of more effective public policies for achieving the environmental and economic targets sought.

| Summary/Abstract |
The aim of this paper is twofold: first, to calculate the "green" energy investments, by industrial sector, that Greece would need in order to satisfy a number of energy and environmental targets adopted in the context of the European Commission's energy and climate change package; and second, to calculate the macro-economic impacts of these "green" investments on production and employment in the Greek economy. To this end, the input-output analysis has been exploited for estimating the direct, indirect and induced macroeconomic effects associated with the implementation of selected energy conservation measures, the promotion of renewable energy technologies, etc. Our findings show that the required investments would reach the amount of €47.9 billion, over the period 2010-2020. These investments will result in an average annual increase of the national product by €9.4 billion, creating simultaneously 108,000 full-time equivalent jobs for the entire period under consideration. The employment generated per €1 million investment is relatively higher in energy saving projects in buildings and transport in comparison with the development of RES in power generation sector.

| Summary/Abstract |
Electricity has played an important role in the economic development of Korea and, thus, has become a critical factor in sustaining the well-being of the Korean people. This study attempts to investigate the impact of electricity price changes on industrial prices and the general price level using input-output (I-O) analysis. To this end, we apply the I-O price model to the 2011 I-O table recently produced by the Bank of Korea, paying particular attention to the electricity sector by considering it as exogenous and then investigating its impacts. The impacts of the electricity price changes on each industrial sector's prices and the general price level are quantitatively derived. For example, the overall impact of a 10% increase in electricity price on the Korean national economy is estimated to be 0.4367%. We also report the results from the model with the electricity sector endogenous and the model with endogenous electricity and labor sectors. This information can be usefully utilized in decision-making regarding price management for electricity.

| Summary/Abstract |
Fossil fuel-related CO2 emissions are regarded as the primary sources of global climate change. Unlike direct CO2 emissions for each sector, CO2 emissions associated with complex linkages among sectors are usually ignored. We integrated the input-output analysis with the hypothetical extraction method to uncover the in-depth characteristics of the inter-sectoral linkages of CO2 emissions. Based on China's 2007 data, this paper compared the output and demand emissions of CO2 among eight blocks. The difference between the demand and output emissions of a block indicates that CO2 is transferred from one block to another. Among the sectors analyzed in this study, the Energy industry block has the greatest CO2 emissions with the Technology industry, Construction and Service blocks as its emission's primary destinations. Low-carbon industries that have lower direct CO2 emissions are deeply anchored to high-carbon ones. If no effective measures are taken to limit final demand emissions or adjust energy structure, shifting to an economy that is low-carbon industries oriented would entail a decrease in CO2 emission intensity per unit GDP but an increase in overall CO2 emissions in absolute terms. The results are discussed in the context of climate-change policy.

| Summary/Abstract |
With an increase in China's oil imports, China's oil supply will also continue to be effected by the socio-economic stability of oil-exporting countries and the safety of oil transport routes. This paper introduces a systematic and quantitative method to evaluate the influence of China's oil import risks (OIR) on the national economy and industrial sectors from a perspective of apply chain process. For this analysis, China's OIR is quantified by integrating oil exporting country risk and the risks from oil transportation routes. Country risk is defined as the oil-exporting country's political risk caused by political changes or internal conflicts. Transport risk is defined as the risk of shipping routes affected by pirate attacks and geopolitics. Second, the relationship between China's OIR and oil import costs is analyzed using a multiple linear approach. Third, an input-output analysis method is used to research the effect of the cost of China's oil imports on the cost of investment within China's domestic sectors. This research finds that the corresponding impact on GDP is 3494.5 million dollars given an increasing by 10% of China's OIR. And the impact on domestic sectors differs from sector to sector. Finally, this paper puts forth recommendations to improve long-term oil supply security in China.

| Summary/Abstract |
The decline of China's energy intensity slowed since 2000. During 2002-2005 it actually increased, reversing the long-term trend. Therefore, it is important to identify drivers of the fluctuation of energy intensity. We use input-output structural decomposition analysis to investigate the contributions of changes in energy mix, sectoral energy efficiency, production structure, final demand structure, and final demand category composition to China's energy intensity fluctuation during 1997-2007. We include household energy consumption in the study by closing the input-output model with respect to households. Results show that sectoral energy efficiency improvements contribute the most to the energy intensity decline during 1997-2007. The increase in China's energy intensity during 2002-2007 is instead explained by changes in final demand composition and production structure. Changes in final demand composition are mainly due to increasing share of exports, while changes in production structure mainly arise from the shift of Chinese economy to more energy-intensive industries. Changes in energy mix and final demand structure contribute little to China's energy intensity fluctuation. From the consumption perspective, growing exports of energy-intensive products and increasing infrastructure demands explain the majority of energy intensity increase during 2002-2007.

| Summary/Abstract |
We compare energy use and greenhouse gas (GHG) emissions associated with total household expenditures and activities in Canada and US in 1997, the first detailed estimate of environmental burdens for Canadian households. We estimate direct burdens from published government data and indirect burdens using an industry-by-commodity, bi-national economic input-output life cycle assessment model developed in this study. Comparing 30 expenditure and two activity categories, per capita US household expenditures were 70% higher, while per capita household energy use and GHG emissions were only 10% and 44% higher, respectively. Energy use/dollar of expenditure was higher in most Canadian categories, while the average ratio of GHG emissions/energy use was higher in the US (65 vs 50 kg Eq. CO2/GJ) due largely to a higher proportion of electricity from nonrenewable sources. Indirect environmental burdens represented 63-69% of total burdens and 62-70% of total burdens were associated with household operation and transportation. Key drivers of differences between energy profiles were: higher per capita electricity use by Canadian households, and higher US household private health care expenditures and motor fuel use. Energy-intensive production for export represented a higher proportion of Canadian production, resulting in less agreement between consumption and production-based analyses for Canada than US.
