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

Union of Concerned Scientists

How would that change if I hopped on the electric bus route at the end of my block? A 2021 meta-analysis of over 40 peer-reviewed studies on the subject concluded that “there is no particular type of shopping that has an absolute environmental advantage and it is in no way possible to shop ourselves out of the environmental crisis.”

The State of the Air in 2024? Not Great

Union of Concerned Scientists

The air quality for this report was calculated using data reviewed by EPA from 2020, 2021, and 2022. That means it includes the extreme wildfires exacerbated by the fossil fuel industry that burned more than 4% of California in 2021 and 2022. We need to reverse climate change.

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

Union of Concerned Scientists

IRA clean energy investments also will protect public health by cutting key toxic air pollutants, such as nitrogen oxides and sulfur dioxide, by more than 50 percent by 2050, and drastically reduce fine particulate matter, which will save hundreds of billions of dollars in 2035 alone from avoided premature deaths. Your thoughts?

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. Even so, cars and trucks are still making us sick—and killing us. I recently caught up with Kevin X.

Ask a Scientist: Gas Plants Disproportionately Harm Marginalized Communities

Union of Concerned Scientists

But in fact, gas power plants are unreliable in extreme temperatures, which—thanks to climate change—have been occurring more frequently. Gas plants and infrastructure emit nitrogen oxides (NOx) during combustion, which degrade local air quality. First, there’s air pollution.

Ask a Scientist: Two Dozen States Can Meet 100 Percent of Electricity Demand with Renewables by 2035

Union of Concerned Scientists

To help avoid the worst possible consequences of climate change, however, the alliance states need to reach that 100-percent objective much more quickly. Emissions of sulfur dioxide and nitrogen oxides from power plants in alliance states drop 88 percent and 77 percent respectively by 2040.

Ohioans Stuck Burning Coal, Burning Cash

Union of Concerned Scientists

Although the nuclear bailout was repealed and refunded in 2021, some of the law’s other egregious provisions requiring ratepayers across the state to subsidize money-losing coal plants and gutting renewable energy and energy efficiency standards are still in place today. Even if you don’t live in Ohio, you may have heard about H.B.
