Development of MAC Emission Test Procedure by the European Commission

Learn about the European Commission's effort to reduce CO2 emissions from vehicles through a MAC test procedure. This initiative aims to incentivize emission reductions and ensure cost efficiency for MAC usage in real driving conditions.

  1. European Commission Enterprise and Industry Directorate General Mobile Air-conditioning (MAC): Development of an Emission test procedure Nikolaus Steininger Automotive Industry Unit Enterprise and Industry Directorate-General European Commission Nikolaus.steininger@ec.europa.eu

  2. MAC test procedure: why? • Communication of the Commission on the review of the Community Strategy to reduce CO2 emissions from passenger cars and light-commercial vehiclesof 2 February 2007 => • Euro 5/6 Regulation 715/2009: pollutant emissions to be limited under normal conditions of use (e.g. use of MAC in “real driving” conditions) • Commission has to prepare a regulatory proposal for the reduction of emissions from the use of MAC systems • Basis of this proposal is a MAC test procedure

  3. MAC test procedure: objectives • Cost-efficient • Should incentivise reduction of emissions resulting from MAC use in real driving: • No “academic” exercise trying to provide the best possible accuracy for environmental impact of MAC use • But designed such that technical measures reducing/not-reducing “MAC emissions” established by the test procedure reduce/do-not-reduce “MAC emissions” in real driving • Suitability for “virtual testing”, which may be developed in parallel or at a latter stage (i.e. availability of virtual testing is no condition for future legislation!) • Assessment of the whole vehicle, including the impact of non-MAC components such as glazing or insulation

  4. MAC test procedure: agenda • Consortium of contractors led by TNO, including partners like TUG and the JRC • Wide participation of stakeholders: Member State experts, vehicle manufacturers, relevant suppliers, consumer organisations (automobile clubs etc.),… • Draft MAC test procedure should be available by August 2010 • Purpose of today’s meeting: • Presentation of a technical project draft by contractors • Contributions of stakeholders to the process • Discussion and consensus on boundary conditions and how to tackle possible barriers
