• COP 10 Side event on 15 December 2004
• Methodology for offsetting the warming impact
  from aviation by Atmosfair
• Manfred Treber, Germanwatch

2
Difference between carbon neutral and climate
neutral

• IPCC 1999 Special Report on Aviation and the
  Global Atmosphere
• Introduction of Radiative Forcing Index
  (RFI)with RFI 2.7 as best estimate
• This means
• To quantify the warming effects of aviation
  emissions the CO2-effect has to be multiplied by
  2.7

• Testcase WSSD Johannesburg, 2002
• German Environment Ministry (BMU)Demand for
  high quality methodology - call for tender
• Germanwatch, Forum anders Reisen (80 travel
  agencies), 500ppm (service provider) -gt
  atmosfair
• Dietrich Brockhagen - expert reviewer IPCC (SR
  Aviation and Global Atm.), german negotiator
  kyoto mechanisms and bunker fuels (1999-2001)

Atmosfair

• Start June 2004 - First references
• Methodology for offset of Renewable Energy
  Conference, Bonn
• German Environmental Ministry
• British Embassy for British-German Climate
  conference (November)
• 80 travel agencies in Germany

Simplicity and Integrity
To remind From scientific viewpoint is is not
possible to offset the emissions completely
because the warming effects of contrails and
cirrus clouds are inevitably there Simplicity
User can opt only 1. relation of those that fly
on average or more specificly 2. on aircraft and
engine type Integrity 1. including the
radiative forcing index (IPCC, 1999) for flights
higher than 9000 m -gt multiply CO2-warming effect
by 2.7 2. Complete emissions (roundabouts,
emissions from rolling on landing fields)

Calculations for Comparison

• Return Flight Heathrow - Cape Town
• Future forests 2130 my climate 3800 atmosfair
  6700
• Return Flight London - Edinburgh
• Future forests 190 my climate 600 atmosfair
  180
• Return Flight London - Tenerife (Charter)
• Future forests 1060 my climate 1800 atmosfair
  1200
• calculated equivalent CO2-emissions to offset

7
Projects to offset the emissions

• For reasons of integrity only CDM-Projects
  which satisfy the Gold Standard are chosen
