The tech giant, which says it has been "carbon neutral" for years, is vowing to go "carbon negative" — by cutting emissions, planting trees and investing in new carbon removal technology.
In the search for alternatives to coal and gas, some European countries have turned to a very old fuel. They're importing wood from the United States. Some environmentalists say it makes no sense.
Carbon emissions from global air travel are rising fast, and U.S. passengers make up the largest share. But some are vowing not to fly at all, motivated by guilt and concern for the environment.
SACRAMENTO, Calif. (AP) — Nevada has joined twenty-two other states in suing to stop the Trump administration from revoking California's authority to set emission standards for cars and trucks.
The young Swedish activist led a protest at the White House on Friday. But she wasn't looking to go inside. "I don't want to meet with people who don't accept the science," she says.
China has taken dramatic steps to fight climate change, including shutting major coal power plants. But now it plans to build hundreds of coal plants abroad.
After several years of nearly no growth in planetary carbon emissions, human-created carbon output is projected to rise again. That means the past few years were a pause, not a peak, researchers say.
The industry has been in decline for years, partly because burning coal creates CO2 and warms the atmosphere. But there's a way to capture it — which has drawn praise from traditional enemies.
The idea behind "clean coal" is technology that would capture for reuse most of the carbon dioxide emitted by coal-burning power plants. Entrepreneurs aim to use similar tech to clean natural gas.
Capturing carbon emissions from coal plants would reduce coal's effect on climate change. But high costs and other factors have stymied efforts to use that technology at more U.S. power plants.
A key piece of the Obama administration's efforts to cut back on carbon emissions faces a test in court on Tuesday. An appeals court is hearing arguments on regulations announced last year.
Biomass was rising a decade ago as a carbon-neutral energy. But the industry is sputtering as oil and natural gas booms, and some scientists are questioning if it's actually good for the environment.
A decision on the Clean Power Plan could be long in coming — meaning that the rules' fate might not be determined before a new presidential administration comes into power in 2017.
Renewable energy is only one of the steps toward achieving the goals set by the Paris climate deal. We take a trip around North America to explore other ways of keeping carbon out of the atmosphere.
The 20th century's biggest carbon emitter is also one of the few advanced democracies where climate change is not accepted as fact. This makes it hard for some to trust U.S. efforts on the issue.
Climate scientists say global emissions of carbon dioxide seem to have dipped a bit in 2015, though the world economy is still growing. China's reduced use of coal may be the main reason.
Companies, once seen as an obstacle to or even an enemy of curbing emissions, now realize that tackling climate change can be good for their bottom line.
Less than two weeks before climate talks in Paris, the U.S., Japan and other wealthy countries have reached agreement on one carbon-cutting issue: limiting financing for coal-burning power plants.
As resale prices drop, the emissions cheating scandal costs customers who want to sell their Volkswagen diesels. "I think it's a tainted product now," says analyst Dave Galvin.
The majority of Americans favor government action, but the candidates — and big donors — differ greatly. Here is what they've said on the topic, beginning with whether climate change is real.
