CO2 emissions,energy consumption and economic growth in China: A panel data analysis

This paper examines the causal relationships between carbon dioxide emissions, energy consumption and real economic output using panel cointegration and panel vector error correction modeling techniques based on the panel data for 28 provinces in China over the period 1995–2007. Our empirical results show that CO₂ emissions, energy consumption and economic growth have appeared to be cointegrated. Moreover, there exists bidirectional causality between CO₂ emissions and energy consumption, and also between energy consumption and economic growth. It has also been found that energy consumption and economic growth are the long-run causes for CO₂ emissions and CO₂ emissions and economic growth are the long-run causes for energy consumption. The results indicate that China's CO₂ emissions will not decrease in a long period of time and reducing CO₂ emissions may handicap China's economic growth to some degree. Some policy implications of the empirical results have finally been proposed.     

Economic growth,energy conservation and emissions reduction: A comparative analysis based on panel data for 8 Asian-Pacific countries

This study was conducted to evaluate the causality between energy consumption, GDP growth and carbon emissions for eight Asia-Pacific countries from 1971 to 2005 using the panel data. The results indicate that there are long-run equilibrium relationships between these variables. Additionally, causality from energy consumption to CO₂ emissions was observed generally, but there were some opposite relationships also. Parameter estimations of the panel data model indicate that there are great differences in the carbon emissions, the efficiencies of energy use, carbon emissions of unit GDP and unit energy consumption between developed and developing countries. The base carbon emissions, per capita energy consumption and efficiency of energy use in developing countries are far lower than in developed countries; however, the CO₂ emissions per unit of energy use is higher. Although developing countries may reduce their CO₂ emission per unit energy use, total energy consumption will rise rapidly with economic development. Thus, developing countries must determine how to undergo economic growth while conserving energy and reducing emissions. To respond to global climate change, it is necessary to develop innovative technology for energy use, transform the energy structure and conduct the clean development mechanism.     

Carbon emissions,energy consumption and economic growth: An aggregate and disaggregate analysis of the Indian economy

This study investigates the long and short run relationships among carbon emissions, energy consumption and economic growth in India at the aggregated and disaggregated levels during 1971–2014. The autoregressive distributed lag model is employed for the cointegration analyses and the vector error correction model is applied to determine the direction of causality between variables. Results show that a long run cointegration relationship exists and that the environmental Kuznets curve is validated at the aggregated and disaggregated levels. Furthermore, energy (total energy, gas, oil, electricity and coal) consumption has a positive relationship with carbon emissions and a feedback effect exists between economic growth and carbon emissions. Thus, energy-efficient technologies should be used in domestic production to mitigate carbon emissions at the aggregated and disaggregated levels. The present study provides policy makers with new directions in drafting comprehensive policies with lasting impacts on the economy, energy consumption and environment towards sustainable development.     

Greenhouse gas emission reduction perspectives in the Baltic States in frames of EU energy and climate policy

The goal of this paper is to estimate the perspectives of the Baltic States: Estonia, Latvia and Lithuania on meeting the new European Union climate commitments, i.e., to reduce greenhouse gas emissions by 20% to the year 2020 in comparison with 1990. This ambitious target could be reached based on other EU climate and energy package commitments: increase of the share of renewables and improvement of energy efficiency as tools for fulfilling the GHG emissions reduction target.The paper gives an overview on the current situation and future plans of the Baltic States in the field of energy efficiency, consumption of renewables and reduction of GHG emissions.     

A multivariate causality test of carbon dioxide emissions,energy consumption and economic growth in China

This paper uses multivariate co-integration Granger causality tests to investigate the correlations between carbon dioxide emissions, energy consumption and economic growth in China. Some researchers have argued that the adoption of a reduction in carbon dioxide emissions and energy consumption as a long term policy goal will result in a closed-form relationship, to the detriment of the economy. Therefore, a perspective that can make allowances for the fact that the exclusive pursuit of economic growth will increase energy consumption and CO₂ emissions is required; to the extent that such growth will have adverse effects with regard to global climate change.     

Achieving deep reductions in US transport greenhouse gas emissions: Scenario analysis and policy implications

This paper investigates the potential for making deep cuts in US transportation greenhouse gas (GHG) emissions in the long-term (50–80% below 1990 levels by 2050). Scenarios are used to envision how such a significant decarbonization might be achieved through the application of advanced vehicle technologies and fuels, and various options for behavioral change. A Kaya framework that decomposes GHG emissions into the product of four major drivers is used to analyze emissions and mitigation options. In contrast to most previous studies, a relatively simple, easily adaptable modeling methodology is used which can incorporate insights from other modeling studies and organize them in a way that is easy for policymakers to understand. Also, a wider range of transportation subsectors is considered here—light- and heavy-duty vehicles, aviation, rail, marine, agriculture, off-road, and construction. This analysis investigates scenarios with multiple options (increased efficiency, lower-carbon fuels, and travel demand management) across the various subsectors and confirms the notion that there are no “silver bullet” strategies for making deep cuts in transport GHGs. If substantial emission reductions are to be made, considerable action is needed on all fronts, and no subsectors can be ignored. Light-duty vehicles offer the greatest potential for emission reductions; however, while deep reductions in other subsectors are also possible, there are more limitations in the types of fuels and propulsion systems that can be used. In all cases travel demand management strategies are critical; deep emission cuts will not likely be possible without slowing growth in travel demand across all modes. Even though these scenarios represent only a small subset of the potential futures in which deep reductions might be achieved, they provide a sense of the magnitude of changes required in our transportation system and the need for early and aggressive action if long-term targets are to be met.     

An energy balance and greenhouse gas profile for county Wexford,Ireland in 2006

In this paper an energy balance and a greenhouse gas profile has been formulated for the county of Wexford, situated in the south east of Ireland. The energy balance aims to aggregate all energy consumption in the county for the year 2006 across the following sectors; residential, agriculture, commerce and industry, and transport. The results of the energy balance are compared with the previous energy balance of 2001 where it is found that the residential sector is the biggest emitter of CO₂ with 38% of total emissions with the transport and industry/commerce sectors sharing second place on 28%. Consumption of oil is seen to have increased significantly in nearly all sectors, accounting for over 70% of the total final energy consumed (TFC) while the total primary energy requirement (TPER) sees oil consumption accounting for 91% of all fuels consumed. To take into account the contribution of agriculture in total GHG emissions the gases CH₄ and N₂O will be estimated from the agricultural and waste sectors. The results show that methane contributes 25% of total GHG emissions with agriculture being the primary contributor accounting for 36% of total emissions.     

Rice straw as a renewable energy source in India, Thailand, and the Philippines: Overall potential and limitations for energy contribution and greenhouse gas mitigation

Rice is a widely grown crop in the South and South-East Asia that leaves substantial quantity of straw in the field. The aim of this paper is to assess the quantity of rice straw produced, estimate Greenhouse Gas (GHG) emissions based on its current uses, and assess its possible energy potential and related GHG emissions mitigation potential. Updated statistics on rough rice production are used in this study in combination with the literature values on Straw-to-Grain Ratio (SGR) to quantify the amount of rice straw produced in the three countries of focus. It is estimated that 97.19, 21.86, and 10.68 Mt of rice straw residue are produced in India, Thailand, and the Philippines, respectively.In India, 23% of rice straw residue produced is surplus and is either left in the field as uncollected or to a large extent open-field burnt. About 48% of this residue produced is subjected to open-field burning in Thailand, and in the Philippines it is 95%. The GHG emissions contribution through open-field burning of rice straw in India, Thailand, and the Philippines are 0.05%, 0.18%, and 0.56%, and the mitigated GHG emissions when generated electricity is used would be 0.75%, 1.81%, and 4.31%, respectively, when compared to the total country GHG emissions.     

Strategies for carbon dioxide emissions reductions: Residential natural gas efficiency,economic, and ancillary health impacts in Maryland

As part of its commitments to the Regional Greenhouse Gas Initiative (RGGI), the State of Maryland, USA, auctions emission permits to electric utilities, creating revenue that can be used to benefit consumers and the environment. This paper explores the CO₂ emissions reductions that may be possible by allocating some of that revenue to foster efficiency improvements in the residential sector’s use of natural gas. Since these improvements will require changes to the capital stock of houses and end use equipment, efficiency improvements may be accompanied by economic and ancillary health impacts, both of which are quantified in this paper.     

Causal links between renewable energy,environmental degradation and economic growth in selected SAARC countries: Progress towards green economy

The objective of the study is to investigate the short-run and long-run causality relationship among energy (electricity production from renewable sources), carbon dioxide emissions, natural resource depletion, Gross Domestic Product (GDP) and poverty in selected SAARC countries, namely, Bangladesh, India, Nepal, Pakistan and Sri Lanka, over a period of 1975–2010. The results show that there is bidirectional Granger causality between carbon dioxide emissions & natural resource depletion in Nepal and between energy production & poverty in Pakistan. For the other three countries, the Granger causality runs from energy production to poverty in Bangladesh and India, and from poverty to energy production in Sri Lanka. The results of panel group Fully Modified OLS (FMOLS) indicates that GDP and poverty has a positive impact while carbon dioxide emission has a negative impact on energy production. Similarly, an increase in energy production leads to decrease in carbon emissions, where as, natural resource depletion increase carbon emissions in selected SAARC countries. Subsequently, an increase in energy production leads to increase in GDP which further increase carbon dioxide emission in SAARC region.     

Welfare distribution effect of a price reduction in the Dutch gas transport market: A scenario analysis of regulatory policy, market form and rent allocation

As part of the larger energy market deregulation program, the Dutch energy authority—DTe—has developed the habit to force the Dutch gas transport enterprise—Gas Transport Services, or GTS—to lower its prices. DTe's key argument is that lower gas transport prices will benefit the end-user. Indeed, that might well be the case. This policy, in general, is in line with European legislation on the liberalization of the gas market. We model and simulate the (domestic) welfare effects of a 5 percent transport price reduction. From this, we conclude that at least three observations complicate matters substantially. First, GTS is government-owned, and the dominant shipper—Gasunie Trade & Supply (or GasTerra, as it was recoined recently)—is partly so (50%). Second, shippers enter into the competitive game to make profits. Third, not only is the majority of gas transported in the Netherlands exported to foreign end-users, but also foreign owners have a large stake in Dutch shippers. As a result, part of the rents will always be distributed, or will ‘leak’ away, to foreign consumers and shippers (or their shareholders). These three observations together have three important implications. First, state ownership implies that much rent allocation is simply a matter of circulating money from one government sub-budget to the other. Second, given that the industry is imperfectly competitive, part of the rents will not be passed on to the end-consumers. Third, it is unavoidable that a substantial part of the rents are transferred abroad. A general conclusion for policy-makers is that market liberalization might not bring ex post what they expected ex ante.     

Economic growth,energy consumption and CO2 emissions in India: a disaggregated causal analysis

This study examines the long-run and short-run causal relationships among energy consumption, real gross domestic product (GDP) and CO₂ emissions using aggregate and disaggregate (sectoral) energy consumption measures utilising annual data from 1971 to 2011. The autoregressive distributed lag bounds test reveals that there is a long-run relationship among the variables concerned at both aggregate and disaggregate levels. The Toda–Yamamoto causality tests, however, reveal that the long-run as well short-run causal relationship among the variables is not uniform across sectors. The weight of evidences of the study indicates that there is short-run causality from electricity consumption to economic growth, and to CO₂ emissions. The results suggest that India should take appropriate cautious steps to sustain high growth rate and at the same time to control emissions of CO₂. Further, energy and environmental policies should acknowledge the sectoral differences in the relationship between energy consumption and real gross domestic product.     

Regional energy efficiency,carbon emission performance and technology gaps in China: A meta-frontier non-radial directional distance function analysis

At present, China is the largest primary energy consumer and carbon emitter in the world. Meantime, China is a large transitional economy with significant regional gaps. Against such backgrounds, the calculated results of energy and carbon performance indicators may be biased, without considering heterogeneity across regions. To this end, after incorporating region-heterogeneity, this paper provides detailed information, regarding energy efficiency, carbon emission performance and the potential of carbon emission reductions from regional perspectives, which may be important and useful for policy makers. Our main findings are as follows. Firstly, there is significant group-heterogeneity across regions in China, in terms of energy efficiency and carbon emission performance. Secondly, there are no considerable differences between total-factor and single-factor performance indices, since there is limited substitutability between energy inputs and other production inputs. Finally, significant carbon emission reductions can be made by “catching up” for regions with low energy efficiency and carbon emission performance. Looking ahead, the Chinese government should adopt measures to promote improvements in terms of energy efficiency and carbon emission performance in the short term.     

Estimation of the potential for reduced greenhouse gas emission in North-East Russia: A comparison of energy use in mining,mineral processing and residential heating in Kiruna and Kirovsk-Apatity

The energy demand at Murmansk Oblast in North-East Russia is covered at 60% by fossil fuels and at 40% by electricity. This study estimates the potential for reduction of fossil fuel consumption and CO₂-emissions at Murmansk Oblast. The study focus on the municipalities of Apatity and Kirovsk and the apatite ore mining company Apatit JSC . The potential for energy efficiency, reduced fossil fuel consumption and greenhouse gas emissions is estimated by comparison with the of city Kiruna in Northern Sweden, with a climate similar to that of North-East Russia, and with the iron ore mining company LKAB. This study shows that the potential for reduced CO₂-emissions is about 630,700 tons CO₂ annually in the municipalities of Apatity and Kirovsk or 6.3 tons of CO₂ per capita, Apatit JSC not included. These results applied on Murmansk Oblast gives a potential for reduced CO₂-emissions of about 6 Mtons annually in the municipalities together. The specific energy consumption at Apatit JSC is 6–7 times per ton product compared to LKAB. The mining has 4 times higher specific energy consumption per ton raw ore compared to LKAB.
