EPA Issues Final Rule on Air Toxics from Existing Stationary Diesel Engines

Green Car Congress

The US Environmental Protection Agency (EPA) has issued a final rule setting the first standards that will reduce emissions of formaldehyde, benzene, acrolein and other toxic air pollutants from certain stationary diesel engines. The emission limits apply to existing diesel engines meeting certain criteria for age, size, and use.

Oxford University Study Finds Downscaling of Vehicle Size and Weight the Best Way to Reduce Transport GHG Emissions in the Short Term

Green Car Congress

An new study from the Smith School of Enterprise and the Environment at Oxford University suggests that best way to reduce transport greenhouse gas (GHG) emissions in the short term is a “drastic downscaling of both size and weight” of conventional gasoline and diesel cars.

Study on Greenhouse Gas Emissions from Global Cities Highlights Importance of Geophysical and Technical Factors

Green Car Congress

By including upstream emissions from fuels, GHG emissions from cities exceed those attributed to direct end-use by up to 24% (for Toronto). By including upstream emissions from fuels, the researchers found that GHG emissions attributable to cities exceed those from direct end use by up to 24%. Tonnes CO 2 e/capita.

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.

Belfer Center report calls for policymakers to begin taking steps to change policies for funding US transportation infrastructure

Green Car Congress

But fuel tax revenues have not kept pace because the federal government and most states have not increased gasoline tax rates since early 1990s, while inflation has eroded their real buying power. User Charges Based on Fuel Consumption (Gasoline and Carbon Taxes). In the meantime, cars and trucks have become more fuel-efficient.
