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 carbon dioxide (CO2) as a refrigerant in passenger cars, and the chemical industry is developing new chemical blends.〔(The Choice Today - New Chemical Blends or CO2 )〕 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.〔(Car Air Conditioning & the Climate Change Challenge - Made Simple )〕 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. ==Background== The Cool War has emanated from the decision of the European Union to phase out the current high global warming refrigerant HFC-134a in car air conditioning from January 2011 onwards.〔(European Directive 2006/40/EC relating to emissions from air-conditioning systems in motor vehicles )〕 To comply with the legislation, carmakers have to decide today on a new refrigerant, as they typically need 3–4 years to develop and introduce a new car platform including the air conditioning system. (It would take much less time to design merely a new air conditioning system to install in a new version of an existing model.) The current total value of the car air conditioning market is estimated to be $14.5 billion in 2007.
