New study tracks corn’s impact county by county

A first-of-its-kind study lays out, on a county-by-county basis, the environmental impact of growing corn in the United States, offering the industry an unprecedented tool for improving sustainability along its supply chain.

Swiss company announces first ‘commercial carbon dioxide capture plant’

The Swiss company Climeworks says it’s the first to develop a “commercial carbon dioxide capture plant” that can suck the greenhouse gas directly out of the air. It’s the kind of solution, some experts say, that is imperative given the dire pace of climate change.

New U.S. look at mileage standards may be an opening for biofuels

An ethanol industry trade group says President Trump's decision to review fuel economy standards for automobiles set by his predecessor could mean a larger role for "high octane, low carbon fuels" such as renewable fuels. Trump announced "the big news that we're going to work on the CAFE (corporate average fuel economy) standards, so you can make cars in America again" during a speech in Detroit.

Last five years were the hottest on record

Biofuels are smaller factor than thought in land conversion

For the most part, farmers put their cropland to more intense use rather than convert forests and grasslands because of demand for biofuels in recent years, says a study by the Center for Agricultural and Rural Development.

Wetlands have role in methane production

Eat less meat, reduce climate change gases

The executive summary of a European study, "Nitrogen on the Table," says if Europe reduced its meat consumption, it "would reduce nitrogen air and water pollution, and greenhouse gas emissions, while freeing up large areas of farmland for other purposes such as food export or bioenergy."
