Technical support for GHG scenario modeling, MACC development, and cost-benefit analysis for the update of the Dominican Republic's NDC 3.0

Project description

To achieve this, Climate Lead Group (CLG) provided technical support to the Government of the Dominican Republic for the update of its NDC 3.0 through the development of integrated, transparent, and policy-relevant analytical inputs. The work focused on generating quantitative evidence to inform mitigation ambition, prioritize measures, and assess economic feasibility. Key activities included the development of national and sectoral greenhouse gas emission trajectories for Business-as-Usual (BAU) and NDC scenarios for the 2025–2035 period, ensuring coherence with national inventories and long-term planning frameworks; the construction of Marginal Abatement Cost Curves (MACC) and the application of cost-benefit analysis to assess mitigation measures based on their emission reduction potential, costs, and co-benefits; and the integration of these analytical outputs to support the definition, justification, and internal consistency of the Dominican Republic’s NDC 3.0 targets and measures. Building on these technical results, the project concluded with targeted capacity-building and knowledge dissemination activities to strengthen institutional ownership and ensure effective use of the generated evidence. This included the design and delivery of training sessions for key national institutions on emissions modeling, interpretation of MACC and cost-benefit analysis results, and their application to climate policy planning and future NDC updates. In addition, the project supported the preparation of a technical-narrative blog proposal for publication by the Inter-American Development Bank, designed to communicate the value of evidence-based decision-making, translate complex analytical outputs into accessible messages, and highlight the role of data-driven tools in strengthening the Dominican Republic’s NDC 3.0.
