What is it? • Tool for computing CO 2 emissions from passenger air travel
What is it used for? • Knowing your aviation carbon footprint • Can be used with offset programs • Verification of reported emissions 3
Climate Neutrality “Climate neutrality” is defined by the entire set of policies that an institution uses when it estimates its known GHG emissions, takes measures to reduce them, and purchases carbon offsets to “neutralize” those emissions that remain - UNEMG (Environmental Management Group) EMG/AM.07/05/Rev.2 The ICAO Carbon Calculator is used UN-wide in support of the Climate Neutral UN Initiative 4
How was it developed? • Methodology developed through technical committee (CAEP) • Experts from ICAO, States, IATA, ICCAIA (manufacturers), NGOs and Universities • Fully documented and best publicly available data • Suitable for use with offset programmes • Methodology is internationally accepted 5
Methodology Origin and Destination Airports Multilateral Pax:Cargo Load CORINAIR Schedules Ratio Factor Database Simple to use CO 2 for Only inputs are airports Selected Trip Great Circle Number of Weighted Average and class of service Distance + Economy Fuel Burn Correction Factor Passengers CO 2 per Class of Service Class of Economy Service Factor Passenger 6
Web Interface www.icao.int • Transparent • Easy-to-use Link to • Publicly available Methodology • Delivers consistent unbiased estimates of CO 2 – suitable for use FAQ with offset programs • Available since June 2008 7
Customization Possible • Designed to facilitate inventory preparation • Desktop interfaces (e.g. Excel) • Direct integration with travel approval systems • Direct integration with Global Distribution Systems 8
Primary Users • The UN system • Amadeus (about 37% of global airline bookings, more than one million per day) • Travelling public • Member States 9
Next Steps • Phased approach for updating methodology and data through CAEP • Formulation of a methodology for air cargo Try it at www.icao.int 10
