Action targets: a new approach to international greenhouse gas controls

This article introduces and explores a new form of international commitment to limit greenhouse gas (GHG) emissions, called an action target. Action targets differ from other forms of targets, such as the Kyoto Protocol's fixed targets, in that they define a quantity of GHG abatement to be achieved, rather than a future emission level to be reached. This article explains the basic mechanics of how action targets might operate, and analyses the approach across a range of criteria, including uncertainty management and contributions to sustainable development in non-Annex I (developing) countries. The analysis suggests that action targets might improve the prospects of widening and deepening developing country participation in the international climate regime.
