The State of the Air in 2024? Not Great

Union of Concerned Scientists

Since its inception, the report has effectively heightened the awareness of some hazardous air pollutants, and engaged the public, media, advocates, and policymakers in the ongoing fight against air pollution. The air quality for this report was calculated using data reviewed by EPA from 2020, 2021, and 2022.

A 100% Renewable Energy Future is Possible, and We Need It

Union of Concerned Scientists

And we’re still trying to recover from a pandemic that has made even more clear the disproportionate impacts of air pollution on overburdened communities, making them even more vulnerable to the negative impacts of COVID 19. A transition to 100 percent renewable energy is about more than just technology.

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.

Ask a Scientist: UCS Transportation Program Adds Equitable Mobility to its Portfolio

Union of Concerned Scientists

In 1963, a typical car—which ran on leaded gasoline without pollution control devices— emitted 520 pounds of hydrocarbons, 1,700 pounds of carbon monoxide, and 90 pounds of nitrogen oxide every 10,000 miles traveled. At the end of 2022, there were more than 283 million. In 1960, there were 61.6 That’s not healthy.

Are There Enough Materials to Manufacture All the Electric Vehicles Needed?  

Union of Concerned Scientists

Research shows there are enough explored or prospective reserves to electrify the global transportation sector using current technology if a high amount of battery recycling occurs. Reserve estimations are therefore much less than total resources and fluctuate based on material value, mineral exploration, and technological development.

Ask a Scientist: The US Has to Do More to Meet Its Carbon Emissions Reduction Goals

Union of Concerned Scientists

The legislation committed nearly $400 billion to support, among other things, wind and solar power, battery storage, electric vehicles, and other clean energy technologies that will make a significant dent in US heat-trapping emissions. Last year, Congress passed the most ambitious climate bill ever enacted, the Inflation Reduction Act.
