European countries say they may pull out of weakened aviation CO2 scheme

T&E has obtained letters from six EU countries informing the UN aviation agency ICAO that they may pull out out of a global carbon offsetting scheme for aircraft emissions if its environmental safeguards are weakened any further. In separate letters, France, the Netherlands, Belgium, Austria, Finland and Norway state that if sustainability rules governing the use of offsets and alternative fuels are watered down any more in negotiations, they will reconsider their participation. The letters are available to download here. T&E has also seen documents that suggest six other EU countries have similarly told ICAO that they will pull out of the scheme, known as CORSIA.

UPDATE: Portugal subsequently made its letter to ICAO available, becoming the seventh European country to publicly state it will reconsider its participation in CORSIA if sustainability rules are further weakened.
