Mexico

During COP29 Mexico announced its commitment to achieve net zero emissions by 2050 (Gobierno de México, 2024d). Among the world’s 20 largest economies (G20), Mexico was the last to announce its commitment to net zero emissions by 2050 (ICM, 2025). Mexico, under the National Strategy on Climate Change, set up the guiding principles for the next 10, 20 and 40 years to be aligned with the Mexican 2030 NDC and the announced 2050 net zero target (Gobierno de México, 2025b).

Aiming for climate neutrality by 2050 is a step in the right direction: transitioning to a low-emissions development pathway in compliance with international climate change commitments. However, Mexico should clearly state its plans for reducing emissions across all sectors of the economy, including LULUCF and update its Long-Term Strategy (LTS) to the UNFCCC to be aligned with the new target.

Given the preliminary nature of the announcement and the lack of detailed information, Mexico’s net zero target is not assessed in this analysis and is rated as “Target information incomplete.” As a result, nine out of the ten key elements used by the Climate Action Tracker to assess good practice in net zero target setting cannot be evaluated.

For further information on the targets Mexico has adopted, see the Targets tab.

The Climate Action Tracker has defined the following good practice for all ten key elements of net zero targets. Countries can refer to this good practice to design or enhance their net zero targets.

Scope

• Target year – Mexico aims to reach net zero by 2050.
• Emissions coverage – Mexico provides no information on the target’s emission coverage.
• International aviation and shipping – Mexico provides no information on its intention to cover international aviation and shipping.
• Reductions or removals outside of own borders – Mexico provides no information on its intention to use international offset credits to meet its net zero target.

Target architecture

• Legal status – José Luis Samaniego and Alicia Bárcena announced the net zero target on 21 November 2024 at COP29 in Baku. As of January 2026, Mexico has not submitted an updated LTS.
• Separate reduction & removal targets – Mexico provides no information on its intention to communicate separate emission reduction and removal targets.
• Review process – Mexico provides no information on its intention to establish a review cycle for its net zero and intermediate targets.

Transparency

• Carbon dioxide removal – Mexico provides no information on its intention to communicate transparent assumptions on carbon dioxide removals.
• Comprehensive planning – Mexico provides no information on its planning to reach its net zero target.
• Clarity on fairness of target – Mexico provides no information on its intention to explain the target’s fairness.
