• #### Accelerated Reduction in $SO_2$ Emissions from the U.S. Power Sector Triggered by Changing Prices of Natural Gas ﻿

(American Chemical Society, 2012)
Emissions of sulfur dioxide ($SO_2$) from the U.S. power sector decreased by 24% in 2009 relative to 2008. The Logarithmic Mean Divisia Index (LMDI) approach was applied to isolate the factors responsible for this decrease. ...
• #### Advantages of a city-scale emission inventory for urban air quality research and policy: the case of Nanjing, a typical industrial city in the Yangtze River Delta, China ﻿

(Copernicus GmbH, 2015)
With most eastern Chinese cities facing major air quality challenges, there is a strong need for city-scale emission inventories for use in both chemical transport modeling and the development of pollution control policies. ...
• #### Analyzing Carbon Price Policies Using a General Equilibrium Model With Household Energy Demand Functions ﻿

(Elsevier, 2020)
Multi-sector general equilibrium models are used to simulate the effects of environmental policies on industry output and consumption at disaggregated levels. The specification of household demand in such models often use ...
• #### Asian emissions of CO and NOx: Constraints from aircraft and Chinese station data ﻿

(Wiley-Blackwell, 2004)
Observations of CO and NOy from the Transport and Chemical Evolution over the Pacific (TRACE-P) aircraft mission over the northwest Pacific and from two Chinese ground stations (Hong Kong and Lin An) during spring 2001 are ...
• #### Black carbon and its correlation with trace gases at a rural site in Beijing: Top-down constraints from ambient measurements on bottom-up emissions ﻿

(Wiley-Blackwell, 2011)
The mass concentrations of black carbon (BC) were measured continuously at Miyun, a rural site near Beijing, concurrently with some trace gases (CO, CO2, NOy, SO2) during the nonheating seasons of 2010 (April to October). ...
• #### Challenges faced by China compared with the US in developing wind power ﻿

(Springer Nature, 2016)
In the 21st Conference of the Parties held in Paris in December 2015, China pledged to peak its carbon emissions and increase non-fossil energy to 20% by 2030 or earlier. Expanding renewable capacity, especially wind power, ...
• #### 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 ...
• #### Constraint of anthropogenic NOx emissions in China from different sectors: a new methodology using multiple satellite retrievals ﻿

(Copernicus GmbH, 2010)
A new methodology is developed to constrain Chinese anthropogenic emissions of nitrogen oxides (NOx) from four major sectors (industry, power plants, mobile and residential) in July 2008. It combines tropospheric NO2 column ...
• #### The Contemporary and Historical Budget of Atmospheric $CO_2$ ﻿

(NRC Research Press, 2012)
Observations of $CO_2$ and $O_2$ are interpreted to develop an understanding of the changes in the abundance of atmospheric $CO_2$ that have arisen over the period 1995–2007. Fossil fuels accounted for an addition ...
• #### Contributions of the Hadley and Ferrel Circulations to the Energetics of the Atmosphere over the past 32-years ﻿

(American Meteorological Society, 2014)
The Hadley system provides an example of a thermally direct circulation, the Ferrel system in contrast an example of a thermally indirect circulation. In this study, we develop an approach to investigate the key thermodynamic ...
• #### Costs for Integrating Wind into the Future ERCOT System with Related Costs for Savings in $CO_2$ Emissions ﻿

(American Chemical Society, 2011)
Wind power can make an important contribution to the goal of reducing emissions of $CO_2$. The major problem relates to the intrinsic variability of the source and the difficulty of reconciling the supply of electricity ...
• #### Designing walkable cities and neighborhoods in the era of urban big data ﻿

(2019)
In this paper, we discuss walkable cities from the perspective of urban planning and design in the era of digitalization and urban big data. We start with a brief review on historical walkable cities schemes; followed by ...
• #### Detection from space of a reduction in anthropogenic emissions of nitrogen oxides during the Chinese economic downturn ﻿

(Copernicus GmbH, 2011)
Rapid economic and industrial development in China and relatively weak emission controls have resulted in significant increases in emissions of nitrogen oxides (NOx) in recent years, with the exception of late 2008 to mid ...
• #### The effects of energy paths and emission controls and standards on future trends in China's emissions of primary air pollutants ﻿
