What’s Happening with California’s Gasoline Supply?

Union of Concerned Scientists

In the next few years, California should modernize its gasoline regulations to reflect changes in vehicle emissions technology and the latest science, which can make the gasoline market more flexible and competitive while protecting air quality and public health. emissions by slightly more than the increase associated with the fuel change.

Ask a Scientist: What’s the Future for Trucks?

Union of Concerned Scientists

These vehicles make up just over 1 in 10 of the vehicles on our roads but emit around half of the fine particulate and nitrogen oxide pollution among on-road vehicles. The technology to enable widescale electrification has grown at impressive rates over a short amount of time, as our new report shows.

Diesel is the Reason for the Sneezin’: Cleaner Holiday Deliveries are on the Horizon

Union of Concerned Scientists

But while greenhouse gas emissions may be reduced, a delivery fulfilled by a diesel-burning truck may lead to increases in emissions of smog-forming nitrogen oxides and lung-damaging particulate matter. The number of available electric truck models in the US and Canada has surpassed 180.

Rural Drivers vs. Disinformation: Three Facts about Electric Vehicles to Set the Record Straight

Union of Concerned Scientists

Electrification involves a transition away from a technology which people have become accustomed to, and change is always challenging. Because EVs are a relatively recent technology, statistics are still being collected on the frequency of maintenance and repairs, but there are some estimates of the cost of predicted repairs and maintenance.
