Mexico submitted its third NDC in November 2025.
Key highlights from the NDC
- Mexico’s third NDC sets a new benchmark for ambition and coherence in climate policy, expanding its implementation horizon to 2035.
- In terms of mitigation, the country commits to a net emissions target of 364–404 MtCO₂e by 2035, unconditionally. In parallel, Mexico introduces absolute targets for black carbon emissions, ranging from 35,800 to 39,700 tons unconditionally.
- The NDC frames adaptation around six axes, including a new one that recognizes climate security as a national priority, linking climate impacts to issues of resource conflicts, migration, and stability.
- For the first time, the NDC includes loss and damage as a dedicated component, addressing climate-induced displacement, risk-transfer mechanisms, and resilient reconstruction.
- Developed under the leadership of SEMARNAT and with the support of UNDP, Mexico’s third NDC is the result of a broad participatory process that engaged subnational authorities, academia, civil society, the private sector, and youth organizations. This inclusive approach ensures that the document reflects both the country’s development priorities and its climate responsibilities, demonstrating how policy coherence and multi-stakeholder dialogue can turn ambition into implementation.
