As fancy microbrews slowly make the transition to 16oz pounder cans, let us take pause and celebrate the macro forefathers that pioneered the God-given right to slug back a watery beer, then slam their containers over your head. They are the beers that guided you through college, the beers that make tailgates possible.
greenhouse gas - a gas that contributes to the greenhouse effect by absorbing infrared radiation. greenhouse emission. CFC, chlorofluorocarbon - a fluorocarbon with chlorine; formerly used as a refrigerant and as a propellant in aerosol cans; the chlorine in CFCs causes depletion of atmospheric ozone.
GHG emissions are often measured in carbon dioxide (CO 2) equivalent. To convert emissions of a gas into CO 2 equivalent, its emissions are multiplied by the gas's Global Warming Potential (GWP). The GWP takes into account the fact that many gases are more effective at warming Earth than CO 2, per unit mass.
