Team upgrades technology for monitoring methane emissions

Researchers at the National Institute of Standards and Technology (NIST) have upgraded a highly precise technology designed to monitor emissions of methane, a critical greenhouse gas, and other trace gases, even in harsh field conditions. Measuring methane emissions and pinpointing their source is an important step toward reducing them—the goal of the Global Methane Pledge recently signed by more than 150 nations at the 2023 United Nations Climate Change Conference.
