methane

New Zealand's government on Tuesday proposed taxing the greenhouse gasses that farm animals make from burping and peeing as part of a plan to tackle climate change. Farmers quickly condemned the plan.

The Nord Stream pipeline leak might be the single largest release of methane, a powerful greenhouse gas. Experts say it pales in comparison to ongoing methane emissions from the oil and gas industry.

Scientists took a dozen research flights over major U.S. oil and gas fields to sample flare emissions. They found more methane than was supposed to be there.

A study builds on research that shows landfills are the third-largest source of methane emissions globally, after oil and gas systems and agriculture.

New Zealand has announced a plan to tax livestock burps in an effort to curb the country's greenhouse gas emissions. It would be the first time a country has done this.

Landfills are among the nation's largest sources of methane, a greenhouse gas far more potent than carbon dioxide. But accurately measuring methane is a major challenge to reducing it.
