How researchers measure wildfire smoke exposure doesn’t capture long-term health effects − and hides racial disparities

Which is riskier for your health: a few days of very bad PM₂.₅ exposure or many more days of slightly bad exposure? Researchers developed new metrics to provide better answers.

Utilities rely on dirty ‘peaker’ plants when power demand surges, but there are alternatives

As renewables account for a growing share of electricity supply, fossil fuel plants are increasingly used to balance fluctuations in renewable generation – emitting health-threatening pollutants.

Native American voices are finally factoring into energy projects – a hydropower ruling is a victory for environmental justice on tribal lands

The Federal Energy Regulatory Commission recently ruled that it won’t approve energy projects on Native lands without tribal consent. But many more applications are pending.

The world is not moving fast enough on climate change — social sciences can help explain why

Climate change is often seen as solely a technical problem. This is a misguided belief. Understanding how to build a better world begins, and ends, with understanding the societies which inhabit it.

Heart attacks, cancer, dementia, premature deaths: 4 essential reads on the health effects driving EPA’s new fine particle air pollution standard

On Feb. 7, 2024, the EPA strengthened the federal limit for annual levels of fine particulate air pollution, or PM2.5. Many serious health effects have been linked to PM2.5 exposure.

Biden’s ‘hard look’ at liquefied natural gas exports raises a critical question: How does natural gas fit with US climate goals?

The US, a minor liquefied natural gas supplier a decade ago, now is the world’s top source. That’s good for energy security, but bad for Earth’s climate. An energy scholar explains the trade-offs.

Citizen science projects tend to attract white, affluent, well-educated volunteers − here’s how we recruited a more diverse group to identify lead pipes in homes

For a project on identifying lead water pipes in homes, outreach through partner groups produced a more representative set of volunteers.

Biden’s strategy for cutting carbon emissions from electricity generation could extend the lives of fossil fuel power plants

After the Supreme Court overturned the Obama administration’s strategy for reducing power plant carbon emissions in 2022, the Biden administration is taking a narrower but still ambitious approach.

Environmental justice has the White House’s attention, building on 40 years of struggle – but California suggests new funding won’t immediately solve deeply entrenched problems

Poor communities of color have spent decades battling US industrial and agricultural pollution. A new EPA office is designed to support their struggle, but history suggests reason for caution.

How to steer money for drinking water and sewer upgrades to the communities that need it most

Congress has approved billions of dollars to fix water and sewer systems across the US. But getting that money to needy communities depends on how states define a key word.

People of color are as interested in buying electric cars as white consumers – the biggest obstacle is access to charging

Reducing air pollution from cars and light trucks would pay big health dividends for low-income and minority communities. A new survey shows how to get more drivers of color into electric vehicles.
