Policy Brief: The EU’s hot air – lifting the fog
A key consideration for the Paris treaty is how to incentivize real additional climate action while avoiding the laundering of bogus hot air credits. Under the Kyoto Protocol the lack of environmental integrity in market mechanisms has resulted in an 11 gigatonne hot air loophole. These hot air units are called AAUs which will not pose a problem for the Paris climate treaty since they cannot be used after 2020. However, the fate of the hot air units of existing domestic emissions trading systems still hangs in the balance.
