Sustainable automotive air conditioning is the subject of a debate – nicknamed the Cool War – about the next-generation refrigerant in car air conditioning. The Alliance for CO2 Solutions supports the uptake of sustainable carbon dioxide (CO2) as a refrigerant in passenger cars, and the chemical industry is developing new chemical blends.
The Alliance and its supporters – scientists, NGOs and business leaders – urge the car industry to replace high global warming chemical substances with the natural refrigerant carbon dioxide (CO2, R744/ R-744) in car cooling and heating. This, they argue, would lead to 10% less car emissions, and knock out 1% of total greenhouse gas emissions worldwide. If CO2 Technology is applied in other sectors, such as commercial and industrial refrigeration, heat pumps for water heating etc., it may even save up to 3% of the world’s greenhouse gases.
Opponents of the Alliance claim that CO2 Technology is not cost-efficient and safe, hence seeking to postpone the global industry decision to be taken to develop new chemical blends instead.

Famous quotes containing the words air and/or conditioning:
“Ancient history has an air of antiquity. It should be more modern. It is written as if the specator should be thinking of the backside of the picture on the wall, or as if the author expected that the dead would be his readers, and wished to detail to them their own experience.”
—Henry David Thoreau (1817–1862)
“The climacteric marks the end of apologizing. The chrysalis of conditioning has once for all to break and the female woman finally to emerge.”
—Germaine Greer (b. 1939)
