In July 2012 the Commission published its proposal to review Regulation 443/2009 which sets CO2 emission targets for new passenger cars. The Environment Committee leads the deliberations in the European Parliament and Thomas Ulmer (EPP) has been appointed rapporteur. This briefing appraises proposals within his report and quantifies how these could lead to a weakening of the target in excess of 10g, raising the target to more than 105g/km.
