Hitting US Climate Targets: Will Electric Trucks Deliver the Goods?

Lewis Fulton and Marshall Miller, , UCS

It was exciting to be part of the discussion in Paris this past December when countries came together to make a renewed commitment to limit climate warming to two degrees or less, with each country committing to what it felt it can deliver. The United States, for its part, has committed to cutting CO2 by 26-28% by 2030 (compared to 2005 levels).

This should be achievable, but there’s one sector in the U.S. that is increasing its CO2 emissions at a rapid pace—trucking. Read more >

Ozone in Houston: Combatting Misinformation and Protecting Public Health

, lead analyst, Center for Science and Democracy

As I’ve been following, the Environmental Protection Agency is in the process of updating the national ambient air quality standard for ozone pollution. The standard is likely to be strengthened below the current standard of 75 ppb, due to the compelling scientific evidence linking ozone to adverse health impacts at this concentration. The EPA has proposed a standard between 65 and 70 ppb, narrowing the range advised by its independent science committee of 60-70 ppb, and the agency will issue a final rule by October. Read more >
