This quality assurance checklist aims to support governments, civil society and other stakeholders during the design, review and revision of Long-Term Low Greenhouse Gas (GHG) Emission Development Strategies (LTSs). The checklist provides a set of guiding questions to be considered when assessing the quality of an LTS, including underlying processes and supporting transformative LTS planning. The guiding questions are organized into three categories: Country Ownership and Inclusiveness; Robustness and Ambition; and Feasibility.
