TL;DR: In this paper, an analysis of emissions inventories shows that per capita emissions from cities are lower than the average for the countries in which they are located, and the role and potential for cities to reduce global greenhouse gas emissions.
Abstract: Cities are often blamed for high levels of greenhouse gas emissions. However, an analysis of emissions inventories shows that - in most cases - per capita emissions from cities are lower than the average for the countries in which they are located. The paper assesses these patterns of emissions by city and by sector, discusses the implications of different methodological approaches to producing inventories, identifi es the main drivers for high levels of greenhouse gas production, and examines the role and potential for cities to reduce global greenhouse gas emissions.

TL;DR: In this article, the authors used the same set of income and population growth assumptions as the Intergovernmental Panel on Climate Change (IPCC) and found that the IPCC's widely used emissions growth projections exhibit significant and substantial departures from the implications of historical experience.
Abstract: Emissions of carbon dioxide from the combustion of fossil fuels, which may contribute to long-term climate change, are projected through 2050 using reduced-form models estimated with national-level panel data for the period of 1950–1990. Using the same set of income and population growth assumptions as the Intergovernmental Panel on Climate Change (IPCC), we find that the IPCC's widely used emissions growth projections exhibit significant and substantial departures from the implications of historical experience. Our model employs a flexible form for income effects, along with fixed time and country effects, and we handle forecast uncertainty explicitly. We find clear evidence of an “inverse U” relation with a within-sample peak between carbon dioxide emissions (and energy use) per capita and per-capita income.

TL;DR: In this paper, the decoupling effect between carbon emissions and economic growth in China has been analyzed, showing that the reduction effect of inhibiting factors of carbon emissions was less than the driving effect of economic growth, and the economy grew with increased carbon emissions.
Abstract: In order to find the efficient ways to reduce carbon emission intensity in China, we utilize the LMDI method to decompose the changes of China׳s carbon emissions and carbon emission intensity from 1996 to 2010, from the perspectives of energy sources and industrial structure respectively. Then we introduce the decoupling index to analyze the decoupling relationship between carbon emissions and economic growth in China. The results indicate that, on the one hand, economic growth appeared as the main driver of carbon emissions increase in the past decades, while the decrease of energy intensity and the cleaning of final energy consumption structure played significant roles in curbing carbon emissions; meanwhile, the secondary industry proved the principal source of carbon emissions reduction among the three industries and had relatively higher potential. On the other hand, when the decoupling relationship is considered, most years during the study period saw the relative decoupling effect between carbon emissions and economic growth, which indicated that the reduction effect of inhibiting factors of carbon emissions was less than the driving effect of economic growth, and the economy grew with increased carbon emissions; there appeared the absolute decoupling effect in 1997, 2000 and 2001, which implied that the economy grew while carbon emissions decreased; whereas no decoupling effect was identified in 2003 and 2004.

TL;DR: Although energy consumption in China went up continuously during the past two decades, annual emission of PAHs fluctuated depending on the amount of domestic coal consumption, coke production, and the efficiency of energy utilization.
Abstract: Emission of 16 polycyclic aromatic hydrocarbons (PAHs) listed as US Environmental Protection Agency (US EPA) priority pollutants from major sources in China were compiled Geographical distribution and temporal change of the PAH emission, as well as emission profiles, are discussed It was estimated that the total PAH emission in China was 25 300 tons in 2003 The emission profile featured a relatively higher portion of high molecular weight (HMW) species with carcinogenic potential due to large contributions of domestic coal and coking industry Among various sources, biomass burning, domestic coal combustion, and coking industry contributed 60%, 20%, and 16% of the total emission, respectively Total emission, emission density, emission intensity, and emission per capita showed geographical variations In general, the southeastern provinces were characterized by higher emission density, while those in western and northern China featured higher emission intensity and population-normalized emission A

TL;DR: Zhang et al. as discussed by the authors quantitatively studied the impact of China's economic growth, industrial structure and urbanization on carbon emission intensity based on the historical data from 1978 to 2011.
Abstract: China’s macroeconomic policy framework has been determined to ensure steady growth, adjust the industrial structure and advance the socioeconomic reforms in recent years. And urbanization is supposed to be one of the most important socioeconomic reform directions. Meanwhile, China also committed to reduce carbon emissions intensity by 2020, then it should be noted that what kind of impact of these policy orientations on carbon emission intensity. Therefore, based on the historical data from 1978 to 2011, this paper quantitatively studies the impact of China’s economic growth, industrial structure and urbanization on carbon emission intensity. The results indicate that, first, there is long-term cointegrating relationship between carbon emission intensity and other factors. And the increase in the share of tertiary industry [i.e., the ratio of tertiary industry value added to gross domestic product (GDP)] and economic growth (here we use the real GDP per capita) play significant roles in curbing carbon emission intensity, while the promotion of population urbanization (i.e., the share of population living in the urban regions of total population) may lead to carbon emission intensity growth. Second, there exists significant one-way causality running from the urbanization rate and economic growth to carbon emission intensity, respectively. Third, among the three drivers, economic growth proves the main influencing factor of carbon emission intensity changes during the sample period.
