An IDDRI-IDB affiliated event of the Latin America and Caribbean Climate Week Thematic Sessions. 

Net-zero CO2 and large reductions in other GHGs are needed by 2050-‘70 to meet the Paris Climate Agreement goals of maintaining +1.5-2°C over preindustrial temperatures. This is technically feasible in Latin America and would have significant air quality, economic and social benefits. The Paris Agreement, by design, puts countries firmly in charge of how to define and accomplish their contribution to the global net-zero effort, and most of the power to achieve it lies with them. The Long-Term Strategies (LTS) asked for in the Paris Agreement, and the process for creating them, can be helpful for the planning, stakeholder engagement and policy package formation required to deliver the Paris climate goals while meeting other development priorities.

At the occasion of the publication of the Spanish translation of the final report of the Deep Decarbonization Pathways in Latin America (DDPLAC) project, this session will present the main policy lessons from this exercise. This project convened and funded by the Interamerican Development Bank (IDB), with the support of the 2050 Pathways Platform and the French Development Agency (AFD), and coordinated by the Institut du Développement Durable et des Relations Internationales (IDDRI), was conducted in Argentina, Costa Rica, Colombia, Ecuador, Mexico and Peru. It was designed to:

  • i) organize technical capacity building on LTS,
  • ii) start building a regional modelling community of practice,
  • iii) develop narrative and quantitative analysis of country-driven  scenarios aligned with domestic socio-economic priorities and deep decarbonization,
  • iv) conduct a structured and sustained engagement with domestic policymakers and stakeholders.

This session will notably discuss how the analysis of long-term transformation pathways towards deep decarbonization and the structured engagement with domestic policymakers and stakeholders around them can be used to inform domestic climate policy processes, their LTS and eventually revised NDCs to the Paris Agreement.
