This guidance provides recommendations to policy makers on how to approach the development of a long-term low greenhouse gas emission development strategy (LTS) given the unique circumstances of individual countries in 2020, and future revisions thereof. It provides country specific cases and introduces three concepts to approach LTS:
- Harmonised revision cycles of LTSs and NDCs can improve the alignment of a country’s long-term vision and medium-term targets and make sure that strategies are grounded in the latest science.
- Three levels of comprehensiveness for LTS development—Base, Intermediate, and Detailed—allow countries to develop LTSs appropriate to their circumstances and can build the scope and detail of their LTS with each revision cycle.
- Eight key aspects for consideration when developing an LTS in a country-specific context informed by recently published literature on LTS development—process, theoretical long-term scenario analysis, long-term GHG and non-GHG target(s), sectoral coverage, link to immediate steps and interim targets (NDC), mobilisation of finance and technology, sustainable development and just transition, and outlook.
