The negotiations under workstream 1 of the Ad hoc Working Group on the Durban Platform for Enhanced Action (ADP) , on a regime which is “applicable to all”, offer an opportunity for LDCs to ensure that the ambition of all Parties is raised. “Applicable to all” does not, however, mean uniformity of action. Of particular importance to the LDCs is the differentiation of approaches to commitments, and the provision of ways to deal with the special circumstances of Small Island Developing States and the LDCs.
