Virgin Earth Challenge
Encyclopedia
The Virgin Earth Challenge is a competition offering a $25 million prize for whoever can demonstrate a commercially viable design which results in the permanent removal of greenhouse gas
Greenhouse gas
A greenhouse gas is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. The primary greenhouse gases in the Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone...

"Entrants must submit a commercially viable design (the “Design”) to achieve the net removal of significant volumes of anthropogenic, atmospheric greenhouse gases each year for at least 10 years without countervailing harmful effects (the “Removal Target”). The removal achieved by the Design must have long term benefits (measured over say 1,000 years) and must contribute materially to the stability of the Earth’s climate."
