The fuel economy of gasoline vehicles will increase to meet 2025 corporate average fuel economy standards(CAFE). However, dedicated compressed natural gas(CNG) and battery electric vehicles (BEV) already exceed future CAFE fuel economy targets because only 15% of non-petroleum energy use is accounted for when determining compliance. This study aims to inform stakeholders about the potential impact of CAFE on life cycle greenhouse gas(GHG) emissions, should non-petroleum fuel vehicles displace increasingly fuel efficient petroleum vehicles.
The European Commission has published the first European Aviation Environmental Report, the result of close collaboration between the EC, the European Aviation Safety Agency (EASA), the European Environment Agency (EEA) and EUROCONTROL.
Road transport is an important source of both greenhouse gases and air pollutants. Despite improvements in vehicle efficiencies over past decades, today the sector is responsible for almost one fifth of Europe's greenhouse gas emissions.
