Mobile air-conditioning systems (MACs)
The European Directive on mobile air-conditioning systems (MACs) aims at reducing emissions of specific fluorinated greenhouse gases in the air-conditioning systems fitted to passenger cars (vehicles of category M1) and light commercial vehicles (category N1, class 1).
In practical terms, the use of the gas that is currently used for filling MAC systems (HFC-134a) is not permitted for newly type-approved vehicles since January 2011. The Commission is informed that automotive manufacturers have decided, in 2009, on the use of refrigerant HFO-1234yf as the technical solution to comply with the Directive's targets. In April 2012, and in light of the exceptional circumstances and exclusively with respect to supply problems of HFO-1234yf, the European Commission accepted to refrain from launching infringement procedures in cases where vehicle production would continue to be done with the gas HFC-134a until 31 December 2012. This solution was inextricably linked to the exceptional circumstances of lack of supply of the refrigerant. Since that problem has been solved, as expected, in the last quarter of 2012, there will be no extension of this solution. Vehicles that have been type-approved for the use of gas HFO 1234yf cannot be registered if they use gas HFC-134a, given that, according to Framework Directive 2007/46/EC, it is not possible for motor vehicles to be registered and marketed in the EU if they are not in conformity with the relevant legislation.
