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? cancel the launch.

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.

The California Air Resources Board released the draft proposed first update to the AB 32 Scoping Plan, which guides development and implementation of California’s greenhouse gas emission reduction programs. The Air Resources Board is required to update the Scoping Plan every five years. —Draft Scoping Plan Update.

That ranks the effects of soot ahead of methane, an important greenhouse gas. Soot could be further reduced by converting vehicles to run on renewable electric power. Black carbon can also absorb light reflecting from the surface, which helps make it such a potent warming agent. Dessler et al., 2008] and methane [Schutz et al.,

Low-input cultivation of perennial plants, e.g. from short-rotation forestry and grasslands, may be an effective source of cellulosic biomass and provide environmental benefits (reduced pollution and lower greenhouse gas emissions). However very few studies include water use impacts. Ravindranath et al. Nitrogen effects: N 2 O and run-off.
