Why Report Carbon Footprints?

• Building credibility public confidence is the
  key
• aviation must be seen to be playing its part
• Without public support there is likely to be
• opposition to airport expansion
• people opting to travel using other modes
• withdrawal of investment

Footprinting Tools

• The big models such as SAGE AERO2K
• most accurate comprehensive
• slow expensive expert black box
• data input/output issues
• City pair calculators
• uncertain accuracy limited application
• readily accessible rapid computation
• commonly not transparent

TNIP Carbon Counter

• Key design features
• readily available input data sets
• rapid access to computations
• non-expert tool
• ICAO fuel computation engine
• Other similar carbon footprinting tools for
  aviation
• Eurocontrol
• Official Airline Guide (OAG)

Potential Applications

• Routine carbon footprint reporting
• total net carbon footprint
• tracking progress to targets
• Environmental assessment (eg EIS, Master
  Plans)
• Assessing policy options
• Computing offsets for corporate travel
• Determining sector footprint (eg tourism,
  mining)

8
Challenges/Issues

• How accurate is this type of approach?
• challenges from black-box modellers airlines
• Transparency how much information should be
  published?
• need to avoid unjustified choices between
  airlines
• What is the carbon footprint of an airport?
• should it include aircraft?
