Greenhouse Gas (GHG) Emissions

Gases that absorb infrared radiation and trap heat in the atmosphere.

GHGs include carbon dioxide, methane, nitrous oxide, ozone, chlorofluorocarbons, hydrochlorofluorocarbons, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride. Release of GHGs into the atmosphere is described as GHG emissions (colloquially referred to as emissions in Project Frame). High concentrations of GHGs in the atmosphere lead to an increase in thermal energy and rising temperatures in the Earth’s land and water.

Project Frame focuses on assessing how innovations we invest in today may result in lower concentrations of atmospheric GHGs in the future. See the EPA definition for more information.
