The first peer-reviewed study to directly quantify how emissions from oil and natural gas (O&NG) activities influence summertime tropospheric ozone (O 3 ) pollution in the Colorado Front Range confirms that chemical vapors from oil and gas activities are a significant contributor to the region’s chronic ozone problem.

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%. The country opened its largest coal-fired power plant in 2012 and has yet to implement emission controls like China.

1 from shipping in 2007, corresponding to 3.3% 1 of the total ship emissions in 2007. In addition to CO 2 , other compounds such as ozone (O 3 ) precursors (nitrogen oxides (NO x =NO+NO 2 ), carbon monoxide (CO), and volatile organic compounds (VOCs)) and aerosols such as black carbon (BC) and organic carbon (OC) are emitted by ships.

exhaust from heavy-duty diesel engines meeting EPA 2007 and later emissions requirements—has found no evidence of carcinogenic lung tumors. The study exposed laboratory rats 80 hours a week, for up to 30 months, to emissions from a heavy-duty diesel engine meeting 2007 US EPA standards using new filters and other control technology.

Meeting the full requirements of the 36 billion gallons per year of biofuel required by the US Energy Independence and Security Act (EISA) of 2007 entirely with ethanol fuel. This is accompanied by a modest regional decrease in surface ozone (of order 1%). Numbers inset give the total North American ethanol source. Click to enlarge.

power from renewable sources—wind, solar, geothermal, biomass or landfill gas, hydropower, and marine and hydrokinetic—for retail electricity suppliers beginning at 6% in 2012 and gradually rising to 25% in 2025 and continuing at that level through 2039. The draft establishes a Renewable Portfolio Standard—i.e., Industrial Energy Efficiency.

A new study led by researchers at the University of Michigan compared regulated and unregulated emissions from both light-duty passenger car (1.7 Unregulated pollutants also include ozone precursors and bioaccumulative and toxic compounds. L engine was operated under both 2004 and 2007 calibrations. Credit: ACS, Chin et al.
