NASA satellite images highlight US air quality improvement with reduction of NO2

Green Car Congress

After ten years in orbit, the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite has been in orbit sufficiently long to show that people in major US cities are breathing less nitrogen dioxide. The gas is produced primarily during the combustion of gasoline in vehicle engines and coal in power plants.

UMD-led study finds China’s SO2 emissions down 75% since 2007, India’s up 50%; India may now be the top SO2 emitter

Green Car Congress

Although China and India remain the world’s largest consumers of coal, a new University of Maryland-led study found that China’s sulfur dioxide emissions fell by 75% since 2007, while India’s emissions increased by 50%. Most of the two countries’ sulfur dioxide emissions come from coal-fired power plants and coal-burning factories.

EPA Proposes Transport Rule to Cut Pollution from Power Plants in 31 States and DC; New Approach for Pollution Reduction

Green Car Congress

This proposal reduces emissions contributing to fine particle (PM 2.5 ) and ozone nonattainment that often travel across state lines. By 2014, the rule and other state and EPA actions would reduce SO 2 emissions by 71% over 2005 levels. NO x emissions would drop by 52%. NO x emissions would drop by 52%. billion in 2014.

New Comprehensive Lifecycle Energy and Emissions Inventory Includes Non-Operational Components; Large Aircraft Can Perform Better than Light Rail

Green Car Congress

Mikhail Chester and Arpad Horvath inventoried on-road, rail, and air travel to determine energy consumption, greenhouse gas (GHG) emissions, and criteria air pollutant (CAP) emissions (excluding PM, lead, and ozone due to lack of data). 83% of rail passenger kilometers are performed by metropolitan systems (with Amtrak serving the remaining).
