Stanford Professor Urges EPA to Include Black Carbon in Endangerment Finding

Green Car Congress

In testimony for the US Environmental Protection Agency (EPA) public hearing ( earlier post ) on the proposed endangerment finding for greenhouse gas emissions under the Clean Air Act ( earlier post ), Stanford Professor Mark Jacobson urged the EPA to include black carbon in the finding. C increased Arctic warming from 1890 to 2007.

CRC ACES Phase 2 report finds emissions from modern heavy-duty diesels well below required levels

Green Car Congress

2010 engines emissions reduction relative to 2010, 2007, and 2004 US emission standards. For a number of the most important pollutants, levels were substantially lower than required by regulations. Emissions of carbon monoxide and hydrocarbons were also significantly below required 2010 levels: 97% and more than 99.9%, respectively.

Study Finds Controlling Soot May Be Fastest Method to Reduce Arctic Ice Loss and Global Warming; Second-Leading Cause of Global Warming After CO2

Green Car Congress

Results of the study suggest that soot is second only to carbon dioxide in contributing to global warming. Jacobson used a computer model of global climate, air pollution and weather that he developed over the last 20 years and updated to include additional atmospheric processes to analyze how soot can heat clouds, snow and ice.

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.

HEI ACES study of lifetime animal exposure to New Technology Diesel Engine exhaust finds no lung cancer

Green Car Congress

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.

EPA Issues Proposed Endangerment Finding for Greenhouse Gases; Proposed Cause or Contribute Finding Identifies Motor Vehicles as Contributing Source

Green Car Congress

After a thorough scientific review ordered in 2007 by the US Supreme Court, the US Environmental Protection Agency (EPA) issued a proposal with two distinct findings regarding greenhouse gases. Climate change has the potential to produce increases in ground-level ozone in many regions, according to the report.

EPRI-NRDC report finds widespread vehicle electrification and a cleaner grid could lead to substantial cuts in GHG by 2050

Green Car Congress

This study builds on the 2007 Environmental Assessment of Plug-in Hybrid Electric Vehicles by EPRI and NRDC ( earlier post ), which showed that plug-in hybrid electric vehicles could contribute to reductions in national greenhouse gas emissions, while also leading to improved air quality. levels throughout the United States.
