Presentation Transcript

  1. Energy in Aviation View from an Aerospace company

  2. What do we include in ‘aviation’ • Civil commercial: • Passenger travel • Freight • Civil government agency • Search and rescue • Police • Medical • Military • Training • Refugee relief • warfare

  3. Effects of aviation on society Good • Air travel • Business • Holidays • Freight movements • Safety & rescue • Aerospace/aviation industry jobs; exports; wealth in economy Bad • Green-house gas emissions • Noise • Land-use • Crashes/danger

  4. Aircraft effects on the environment • Aircraft fuel combustion gases: • CO2; NOX; O3; hydrocarbons • Contrails; cirrus formation • Aircraft noise • Aircraft manufacturing processes • Aircraft servicing processes

  5. Related impacts • Land use for airports • Ground transportation to airports eg car travel • Freight transport to airports

  6. Industry/SBAC actions • Impact of aviation is important • Industry and SBAC seeking solutions • Established working committees and action groups • Reports; programmes; commitments for action and change

  7. Focus for this discussion • Energy use for flying aircraft • Land use for an airport

  8. Energy use for aircraft • Greenhouse gas production from aircraft: • CO2; NOX; O3; hydrocarbons • About 36 million tonnes of CO2 are produced by aircraft in the skies over the UK • This represents about 5% of the CO2 generated in the UK • Growth rate of about 6% per annum

  9. Mechanisms for energy/CO2 reduction • New engine technology • Better aerodynamic design • Larger aircraft • ‘better’ air traffic control • Bio-fuels • Carbon offsets • Carbon trading • Fuel tax

  10. Or…. FLY LESS

  11. Progress on CO2 reduction • 1960 – 1990 = 70% reduction in fuel per RTK • 1990 – 2004 = 24% reduction in fuel RTK RTK = revenue tonne kilometre

  12. ACARE emission targets • 50% improvement in fuel efficiency per seat kilometre • 80% reduction in NOX generated • By 2020 on new aircraft of 2020 vs aircraft of 2000

  13. Land use for Cambridge airport • Cambridge Airport covers about 730 acres of land within the Cambridge City green-belt • Has a 1965 metre Category 1 runway • About 130 aircraft movements a day (on average)

  14. Change of ‘zoning’ • Cambridge Airport has been in the ‘green-belt’ and therefore not eligible for housing development • There has been a local campaign to stop flying from Cambridge Airport • The UK government wants to see an increase in housing in the South East, eg Cambridge • Current plans are to remove Cambridge Airport from the green-belt and ‘re-zone’ it for housing

  15. Status • These plans are under development and have not been confirmed • Marshall Aerospace would move to another location; possibly Alconbury, Wyton or Mildenhall • Other locations are all pleased to have Marshall re-locate

  16. Environmental issues • Marshall Aerospace has an environmental team to ensure compliance with all relevant legislation • In addition, there is an Environmental Committee that aims to identify changes that will reduce environmental impact

  17. Summary: aviation • The aviation industry is a major contributor to the UK economy • Air travel; holidays; business trips • New aerospace products • Businesses and jobs • Wealth in the economy • Air travel is here to stay: we need • New technologies to reduce impact • A sustainable growth rate

  18. Summary: Marshall • Focus on higher value-add products and service lines • Introduce energy saving and environmental savings wherever possible • Work with aircraft manufacturers to make aircraft more environmentally sustainable
