Inequitable Exposure to Air Pollution from Vehicles in Maryland

, Senior vehicles engineer

Most people know that cars, trucks, and buses from our highways and city streets are a significant source of harmful air pollution. While this pollution impacts all communities in the state to some degree, Marylanders who face the greatest exposure to transportation pollution are those who live near highways, along major freight corridors, and in urban areas.

TCI is a Strategy to Enforce Limits on Transportation Pollution

, policy analyst

The Baker administration may be on the verge of leading the Northeast towards a major advance in climate policy.

The Transportation and Climate Initiative (TCI), if successful, would establish the region’s first mandatory and enforceable limits on pollution from transportation, now the largest source of emissions.in Massachusetts and the Northeast.

Trump Administration Goes After States for Protecting the Environment

, research and deputy director, Clean Vehicles

The Trump administration has been on a collision course with California, and it appears that collision is imminent. An administrative action to undermine the authority granted to the state by the Clean Air Act to protect its citizens from vehicle pollution appears to be imminent. This illegal attack is not just harmful for the nation’s most populous state—it is an attack on the 13 states and the District of Columbia that follow California’s lead and, ultimately, the entire country. The American auto industry and the American public will be worse off as a result.

Why Colorado Needs a Zero Emission Vehicles Standard

, Senior vehicles engineer

Colorado is poised to enact requirements for automakers to sell “Zero Emission Vehicles” (ZEVs) in the state. In 2018, Colorado was already in the top 5 states in terms of percent of vehicle sales that are electric in the country, so why is this important? It’s because despite progress, Colorado could be moving even faster to switch from gasoline to electricity to power cars and trucks, if there were more models of electric vehicles available.

New Electric Options for Drivers Looking to Cut Carbon Emissions

, Senior vehicles engineer

Electric vehicles can significantly reduce the emissions from driving by substituting increasingly cleaner electricity for gasoline. At UCS we’ve been tracking how the difference between gasoline and electric car emissions have been changing and where in the US has the lowest electric vehicle emissions.  In 2018, UCS updated our estimates of the carbon emissions of electric vehicles with latest electricity data and now we’ve updated our vehicle emissions calculator with the latest models to reflect the carbon emissions savings from these new vehicles.
