EFE will validate engine technologies in the increasingly important area of environmental performance - delivering significant reductions in carbon dioxide and nitrous oxide emissions and engine noise - to move future engines closer towards goals established by the Advisory Council for Aeronautics Research in Europe (ACARE). These seek to achieve (by 2020, based on a 2000 datum):

• A 50 per cent reduction in carbon dioxide emissions - 20 per cent from engines alone
• An 80 per cent reduction in emissions of nitrous oxides
• A halving of perceived noise levels

The EFE programme is aimed at developing UK aerospace capabilities in the following fundamental technologies:

• High temperature materials
• High efficiency turbine components
• Low emissions combustion
• Advanced manufacturing technologies
• Engine controls and actuation technologies
• Nacelle aerodynamic technologies
