(1) Aircraft and Engine Technology Aspects of Emissions Reduction

• Future developments in aircraft & aero- engine technologies and their impact on emissions
• Aviation fuels - composition, additives and alternatives - and their impact on emissions
• Engine exit emissions, including particulates, aerosols and aerosol precursors
• Emissions measurement and modelling capabilities
• Emissions prediction methodologies
• Emissions - noise interactions and dependence upon technology

• Emissions Inventories and long term scenarios
• Future developments in CNS/ATM and aircraft operations and their impact upon emissions
• The potential of green route networks
• Aircraft operations in relation to contrail formation
• Emissions predictions for whole flight profile and future regulations
• Optimised fuel and emissions per passenger or ton- kilometers
• Airport operations

• Future developments in the air transport system, including aircraft and engine technology, aircraft operations and infrastructure, institutional aspects in relation to atmospheric impact requirements
• Regulatory or market- based options/measures to reduce aviation emissions versus uncertainties in atmospheric science
• Inter- modal transport or substitution
• Green route networks
• Airport issues

• Dialogue between policy makers and AERONET partners
• Information exchange in both directions:
  Consultation and advice on:
  • Policy drivers - environmental lobby, political pressures
  • Regulation and legislation situation - EU, ICAO, ECAC
  • Gaps and needs in RTD activities for the definition and in the execution of the Work Programme.
