Banking and Exchange Programs to Mitigate Vehicle Miles Traveled

Legal Planet

Lets fast forward to today; more than half a century of government housing policy favoring sprawling, car-dependent development has spawned long commutes, increased exposure to air pollution, and segregated communities. And across the United States, the transportation sector is now the largest source of greenhouse gas (GHG) emissions.

Fossil Fuels Must Go: Re-inventing US Transportation

Union of Concerned Scientists

Their contribution to local air pollution is also highly disproportionate, as heavy-duty vehicles are responsible for 45 percent of on-road nitrogen oxides (NOx) and 57 percent of on-road fine particulate matter (PM2.5) by 13 percent and other key pollutants such as nitrogen oxides and sulfur dioxide by 77 and 90 percent, respectively.

Inside the IPCC 61st Plenary Meeting: Debates and Decisions Shaping Climate Policy

Union of Concerned Scientists

The IPCC is a collaborative panel consisting of 195 member governments. Representatives of these member governments convene in Plenary Sessions, like the one we just attended. Each country sends delegations that can include both government officials and scientific experts, collectively forming the Panel.

California Ready to Take Giant Leap Toward Zero-Emission Trucks

Union of Concerned Scientists

million commercial trucks on California roads, and although they make up just seven percent of vehicles on the road, these trucks are responsible for more than one-quarter of greenhouse gas (GHG) emissions, more than 60 percent of smog-forming nitrogen oxides (NOx) and more than 55 percent of lung- and heart-harming fine particulate (PM2.5)

Clean Fleets Rule Slated to Deliver Healthier Air for Californians

Union of Concerned Scientists

Trucks and buses on California’s roads and highways are responsible for the majority of lung-damaging fine particulate and ozone-forming nitrogen oxide emissions, and a sizable amount of climate-warming greenhouse gas emissions as well. Both the state and federal governments have committed billions of dollars to spur this work.

These Are the Critical Issues to Track with the New “Tech-Neutral” Clean Electricity Tax Credits

Union of Concerned Scientists

Most prominently, because the approach is changing from rewarding specific technologies to rewarding anything that meets the greenhouse gas (GHG) emissions threshold of “clean”—hence the “tech-neutral” label—exactly how the government goes about determining whether or not something is actually eligible will be enormously important.

Changes to California’s Electric Truck Proposal Could Reap Huge Climate and Air Quality Gains

Union of Concerned Scientists

The Advanced Clean Fleets (ACF) rule has the potential to significantly reduce climate-warming greenhouse gas (GHG) emissions as well as harmful air pollutants like fine particulates (PM2.5) and nitrogen oxides (NOx) from the numerous commercial and government fleets of MHD vehicles in the state.
