In accordance with Article 4, para. 19, of the Paris Agreement, all Parties should strive to formulate and communicate long-term low greenhouse gas emission development strategies, mindful of Article 2 taking into account their Common But Differentiated Responsibilities and Respective Capabilities, in the light of different national circumstances. The Conference of the Parties to UNFCCC (COP), by its decision 1/CP 21, para. 35, invited Parties to communicate such strategies by 2020. Conducting a scoping study focusing on the development of LTS in AMS was identified as one of the key activities under the ASEAN Working Group on Climate Change (AWGCC) Action Plan within the Action Line “Strengthening science and policy interface in climate change related decision-making process” led by Indonesia, which is one of three Action Lines prioritised by the EU and the AWGCC.

The main purpose of the study is to identify the priorities, the direction and the extent of ASEAN interventions related to LTS as well as to lay out the specific stepping stones to advance the LTS agenda in the ASEAN region. Doing so, the study aims to provide an answer to the question: How can ASEAN and AMS best move forward in the LTS formulation process, taking into consideration good global practices and the regional circumstances?
