We rate Mexico’s mitigation targets “Insufficient.” The “Insufficient” rating indicates that Mexico’s climate commitment in 2030 is not consistent with holding warming to below 2°C, let alone limiting it to 1.5°C as required under the Paris Agreement, and is instead consistent with warming between 2°C and 3°C. If all countries were to follow Mexico’s approach, warming would reach over 2°C and up to 3°C. This means Mexico’s climate commitment is at the least stringent end of what would be a fair share of global effort, and therefore not consistent with the Paris Agreement’s 1.5˚C limit, unless other countries make much deeper reductions and comparably greater effort.
Furthermore, Mexico’s plans to not increase its 2030 mitigation ambition is contrary to the Paris Agreement’s requirement that each successive NDC should represent a progression on their mitigation efforts. This sends negative signals to the international community that Mexico is not serious about its commitment to reduce GHG emissions in line with the Paris Agreement climate goals.
The CAT ratings are based on climate commitments in NDCs. If the CAT were to rate Mexico’s projected emissions levels in 2030 under current policies, we would rate Mexico “Highly Insufficient,” indicating that Mexico’s current policies in 2030 are not consistent with holding warming to below 2°C, let alone limiting it to 1.5°C as required under the Paris Agreement, and are instead consistent with warming between 3°C and 4°C: if all countries were to follow Mexico’s approach, warming could reach over 3°C and up to 4°C. This means Mexico’s current policies are not in line with any interpretation of a “fair” approach to the former 2°C goal, let alone the Paris Agreement’s 1.5°C limit.
