What are Scope 1, 2, and 3 Greenhouse Gas Emissions?
A greenhouse gas (GHG) is a gaseous compound with the ability to trap heat (or longwave radiation) in the Earth’s atmosphere. This results in high temperatures being retained in the lower atmosphere, thus allowing less heat to escape back to space. Common GHGs present in the atmosphere include fluorinated gases (chlorofluorocarbons (CFCs) (e.g., tetrafluoromethane (CF4)) and ...
