(a) Application of Principles of Convention
Equity, including a dynamic approach to common but differentiated responsibilities and respective capabilities (CBDRRC), must be at the very heart of the Durban Platform for Enhanced Action Workstream 1 if it is to be able to deliver adequately for the climate. The internationally legally binding protocol now under negotiation must include common and accurate accounting, MRV, strong compliance and enforcement, all respecting the principles of equity, including CBDRRC. It must have fair targets and actions that are consistent with the strong likelihood of meeting a 2°C global carbon budget, and thus keeping 1.5°C budget within reach. It should build on, develop and improve the rules already agreed under the Convention and the Kyoto Protocol.
The failure to consider equity principles for a global effort sharing agreement – an equitable approach to sharing the costs of mitigation and adaptation amongst countries – has been a stumbling block to agreeing sufficient ambition. Adaptation must be treated with the same importance as mitigation. Countries are concerned that they will be asked to do more than is their fair share, and conversely that other countries will ‘free ride’ off their efforts. A common understanding of fair shares can help overcome this trust barrier and lead to higher levels of ambition from all. Countries must urgently start their work to increase understanding of, and further agreement on, ways and options for the allocation of fair shares of the global effort.
