Ranges in passenger occupancy can easily change the relative performance of modes, with large aircraft performing better than light rail in some of the areas investigated. Samples of the findings include: Off-peak urban diesel buses has the largest energy consumption and GHG emissions per PKT, followed by the three light-duty vehicles.

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather? Not everyone agrees.

Soot—black and brown particles that absorb solar radiation—comes from two types of sources: fossil fuels such as diesel, coal, gasoline, jet fuel; and solid biofuels such as wood, manure, dung, and other solid biomass used for home heating and cooking around the world. For perspective, net warming in the Arctic has been at least 2.5

Finally, our results demonstrate that improving our knowledge of aerosol-climate interactions is important not only for better understanding the aerosol contribution to past and future climate change, but even for correctly evaluating the effects of long-lived greenhouse gas emissions from methane-oxidant-aerosol interactions.

Increased use of coal relative to other energy sources has reversed the long?standing term potential as electric buses, light duty and 2?wheel Additionally, reducing transport emissions of particulate matter (including black carbon), tropospheric ozone and aerosol precursors (including NO x ) can have human health and mitigation co?benefits

Researchers at the University of Colorado, Boulder and the National Renewable Energy Laboratory (NREL) modeled the emissions impact had plug-in hybrid electric vehicles (PHEVs) replaced light duty gasoline vehicles in the Denver, Colorado area in summer 2006. Ozone concentration increases were modeled for small areas near central Denver.

The bill also directs the President to work with the relevant Federal agencies and California to harmonize, to the maximum extent possible, the federal fuel economy standards, any emission standards promulgated by EPA, and the California standards for light-duty vehicles. light duty vehicles—e.g., Clean Fuels and Vehicles.
