Energy in Aviation

View from an Aerospace company

what do we include in aviation
What do we include in ‘aviation’
  • Civil commercial:
    • Passenger travel
    • Freight
  • Civil government agency
    • Search and rescue
    • Police
    • Medical
  • Military
    • Training
    • Refugee relief
    • warfare
effects of aviation on society
Effects of aviation on society


  • Air travel
    • Business
    • Holidays
  • Freight movements
  • Safety & rescue
  • Aerospace/aviation industry jobs; exports; wealth in economy


  • Green-house gas emissions
  • Noise
  • Land-use
  • Crashes/danger
aircraft effects on the environment
Aircraft effects on the environment
  • Aircraft fuel combustion gases:
    • CO2; NOX; O3; hydrocarbons
    • Contrails; cirrus formation
  • Aircraft noise
  • Aircraft manufacturing processes
  • Aircraft servicing processes
related impacts
Related impacts
  • Land use for airports
  • Ground transportation to airports eg car travel
  • Freight transport to airports
industry sbac actions
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
focus for this discussion
Focus for this discussion
  • Energy use for flying aircraft
  • Land use for an airport
energy use for aircraft
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
mechanisms for energy co 2 reduction
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


progress on co 2 reduction
Progress on CO2 reduction
  • 1960 – 1990 = 70% reduction in fuel per RTK
  • 1990 – 2004 = 24% reduction in fuel RTK

RTK = revenue tonne kilometre

acare emission targets
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
land use for cambridge airport
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)
change of zoning
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
  • 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
environmental issues
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
summary aviation
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
summary marshall
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
