1 MAC generated GHG emissions
Enterprise and Industry Directorate-General MACTP-03-03 European Commission European strategy on MAC generated GHG emissions GRPE, UNECE Geneva 17 January 2012

2 MAC & GHG emissions Direct greenhouse gas (GHG) emissions:
Typical refrigerants have very high greenhouse warming potential (GWP) Release of refrigerant during operation, maintenance end of life Indirect greenhouse gas (GHG) emissions: MAC operation leads to significantly increased fuel consumption/CO2 emissions of the vehicle

3 MAC: direct GHG emissions
MAC Directive 2006/40/EC: Greenhouse warming potential (GWP) of passenger car refrigerants < 150 x GWP(CO2) - As of 1 January 2011 for all new types of vehicles approved - As of 1 January 2017 for all new vehicles registered Various provisions on handling of refrigerant (training etc.) NB: Today’s standard refrigerant R-134a has a GWP of about 1430 x GWP(CO2)

4 MAC: indirect GHG emissions
Operation of MACs leads to substantial, additional fuel consumption/CO2 emissions Technically there is a great potential for improvement at small costs, “low hanging fruits” Commission Communication of February 2007 on the integrated approach for reducing automotive CO2 emissions identifies MAC as target of regulation

5 MAC: indirect GHG emissions
Type approval test procedure for MAC energy efficiency in vehicle developed by TUG/TNO with stakeholders on behalf of Commission (test with MAC on/off on chassis dyno) Test can be performed in “normal” test lab without special facilities (heating, humidification, solar lamps,..) => low costs Potential for virtual testing (numerical simulation) of defined test procedure in the future Pilot test phase ongoing, to be finished in 3rd quarter 2012 MAC test procedure drafting & regulatory amendments in early 2013 Should be applied to Euro 6 vehicles, MAC CO2 emissions to be recorded in certificate of conformity (CoC)

6 MAC: indirect GHG emissions
MAC CO2 emissions in CoC. So what. And then? Consumer awareness => incentive for improving MAC energy efficiency. Sufficient? Specific limit values for MAC energy efficiency? Probably not in the near future… Include MAC CO2 emissions in value for overall CO2 emissions of the vehicle for the purposes of CO2 fleet limits. Possible after revision of automotive CO2 Regulation 443/2009/EC Political decision is necessary, discussion to be started by end 2012
