Energy in Aviation

View from an Aerospace company

What do we include in aviation l.jpg
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 l.jpg
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 l.jpg
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 l.jpg
Related impacts

  • Land use for airports

  • Ground transportation to airports eg car travel

  • Freight transport to airports

Industry sbac actions l.jpg
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 l.jpg
Focus for this discussion

  • Energy use for flying aircraft

  • Land use for an airport

Energy use for aircraft l.jpg
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 l.jpg
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

Slide10 l.jpg


Progress on co 2 reduction l.jpg
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 l.jpg
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 l.jpg
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 l.jpg
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

Status l.jpg

  • 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 l.jpg
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 l.jpg
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 l.jpg
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
