The researchers analyzed extensive satellite and ground-based measurements of nitrogen oxides and carbon monoxide. They found that levels of pollutants that can contribute to the formation of ground-level ozone, or smog, have failed to continue a fairly steady decline as estimated by the US Environmental Protection Agency.

Since 1990, nationwide air quality has improved significantly for the six common air pollutants: ground-level ozone; particle pollution; lead; nitrogen dioxide; carbon monoxide; and sulfur dioxide, according to the US Environmental Protection Agency (EPA) report “Our Nation’s Air - Status and Trends through 2008”. annual PM 2.5

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). Peak urban diesel buses showed the best overall energy consumption and GHG emissions per PKT.

In 2005, Congress enacted the Renewable Fuel Standard as part of the Energy Policy Act (EPAct) and amended it in the 2007 Energy Independence and Security Act (EISA). All volumes, except for volumes of biomass-based diesel, are in gallons of ethanol-equivalent. Economic effects. Barriers and opportunities.
