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.

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.
The same, however, cannot be said for inventions that remove GHGs from the atmosphere. As a result, human activity today generates about 50 more gigatonnes of GHG emissions annually than it did centuries ago (PDF). Enter Carbon Dioxide Removal (CDR), which is equivalent to generating negative GHG emissions.. That is, a CDR solution captures more CO2 and other GHGs from the atmosphere than it releases, and prevents it from returning to the atmosphere for long periods of time.
