Study on the carry-over of AAUs from CP1 to CP2: future implications for the climate regime

The report finds a significant surplus of Assigned Amount Units (AAUs) from the first Kyoto commitment period (CP1), totaling 12,637 Mt, which vastly exceeds the estimated demand of 11.5 Mt. It notes that the ability to carry over these surpluses to the second commitment period (CP2) depends on a country's participation in CP2, meaning Russia's stated intent not to join would remove 5.8 Gt CO2e from the available surplus.

• The total balance of AAUs from the first Kyoto commitment period (CP1) is estimated at 12,637 Mt in surplus. If Canada is excluded due to its withdrawal from the Kyoto Protocol, the net surplus increases to 13,127 Mt, a figure that is over three magnitudes higher than the estimated demand of 11.5 Mt.
• Under current Kyoto rules, only countries participating in a commitment period with an emissions reduction target can trade AAUs. Because Russia has indicated it does not plan to join the second commitment period (CP2), its 5.8 Gt CO2e surplus would be removed from the amount of CP1 AAUs carryable to CP2, resulting in a remaining CP1 total of 7.3 Gt CO2e.
