• #### China's CO2 emissions estimated from the bottom up: Recent trends, spatial distributions, and quantification of uncertainties ﻿

(Elsevier BV, 2012)
China’s emissions of anthropogenic CO2 are estimated using a bottom-up emission inventory framework based on a detailed categorization of economic sectors and provincial economic and energy data. It includes a newly compiled ...
• #### CO emissions in China: Uncertainties and implications of improved energy efficiency and emission control ﻿

(Elsevier BV, 2012)
A bottom-up methodology and an improved database of emission factors combining the latest domestic field measurements are developed to estimate the emissions of anthropogenic CO from China at national and provincial levels. ...
• #### CO2 and its correlation with CO at a rural site near Beijing: implications for combustion efficiency in China ﻿

(Copernicus GmbH, 2010)
Although China has surpassed the United States as the world's largest carbon dioxide emitter, in situ measurements of atmospheric CO2 have been sparse in China. This paper analyzes hourly CO2 and its correlation with CO ...
• #### The effects of energy paths and emission controls and standards on future trends in China's emissions of primary air pollutants ﻿

(Copernicus GmbH, 2014)
To examine the efficacy of China’s actions to control atmospheric pollution, three levels of growth of energy consumption and three levels of implementation of emission controls are estimated, generating a total of nine ...
• #### The effects of recent control policies on trends in emissions of anthropogenic atmospheric pollutants and CO2 in China ﻿

(Copernicus GmbH, 2013)
To examine the effects of China's national policies of energy conservation and emission control during 2005–2010, inter-annual emission trends of gaseous pollutants, primary aerosols, and CO2 are estimated with a bottom-up ...
• #### Emission trends and mitigation options for air pollutants in East Asia ﻿

(Copernicus GmbH, 2014)
Emissions of air pollutants in East Asia play an important role in the regional and global atmospheric environment. In this study we evaluated the recent emission trends of sulfur dioxide (SO<sub>2</sub>), nitrogen oxides ...
• #### Evaluating the effects of China's pollution controls on inter-annual trends and uncertainties of atmospheric mercury emissions ﻿

(Copernicus GmbH, 2015)
China’s anthropogenic emissions of atmospheric mercury (Hg) are effectively constrained by national air pollution control and energy efficiency policies. In this study, improved methods, based on available data from domestic ...
• #### The impact of Production Tax Credits on the profitable production of electricity from wind in the U.S. ﻿

(Elsevier BV, 2011)
A spatial financial model using wind data derived from assimilated meteorological condition was developed to investigate the profitability and competitiveness of onshore wind power in the contiguous U.S. It considers not ...
• #### An inventory of primary air pollutants and CO2 emissions from cement production in China, 1990–2020 ﻿

(Elsevier BV, 2011)
Direct emissions of air pollutants from the cement industry in China were estimated by developing a technology-based methodology using information on the proportion of cement produced from different types of kilns and the ...
• #### Multiple effects and uncertainties of emission control policies in China: Implications for public health, soil acidification, and global temperature ﻿

(Elsevier BV, 2011)
Policies to control emissions of criteria pollutants in China may have conflicting impacts on public health, soil acidification, and climate. Two scenarios for 2020, a base case without anticipated control measures and a ...
• #### Optimal Integration of Offshore Wind Power for a Steadier, Environmentally Friendlier, Supply of Electricity in China ﻿
