reducing emissions

Scientists have produced additional evidence confirming that greenhouse gas emissions by humans are the primary force driving global warming.

One in seven new cars sold in California in 2025 must be zero-emission or plug-in hybrid, according to new regulations recently approved by the California Air Resources Board.

A new study in Science identifies 14 key air pollution control measures that, if implemented, could slow mean global warming by 0.9 degrees F by 2050, as well as increase global crop yields and prevent premature deaths. The control measures target black carbon and methane emissions.

On the heels of a great victory for the California Air Resources Board (ARB) with a superior court ruling giving the go-ahead to implement its cap-and-trade system, a federal district judge in Fresno has now ruled that California’s Low Carbon Fuel Standard violates the U.S. Constitution.

A new study published in Nature Climate Change finds that policies focused on mitigating climate change would provide an effective means to simultaneously reduce air pollution, improve energy security, and achieve energy sustainability.

Aerosols—small atmospheric particles such as soot and dust—can alter precipitation frequency and intensity, according to a recent study published in Nature Geoscience. Science Daily explains that the scientists used at

New studies both confirm global warming and warn there is little time left to keep warming below 2˚C from pre-industrial levels, the target needed to avert dangerous climate change. Berkeley Earth has submitted four papers for peer review that confirm the amount of warming determined by earlier studies.

The Department of Energy finalized a loan guarantee to support the Ormat geothermal power generation project in Nevada, which is expected to produce enough electricity to power about 88,000 homes from three different facilities in the western part of the state.

A recent study in Climatic Change finds that the substitution of natural gas for coal initially increases global warming for many decades, rather than decreasing it as previously thought.
