Critically Insufficient4°C+
World
NDCs with this rating fall well outside of a country’s “fair share” range and are not at all consistent with holding warming to below 2°C let alone with the Paris Agreement’s stronger 1.5°C limit. If all government NDCs were in this range, warming would exceed 4°C. For sectors, the rating indicates that the target is consistent with warming of greater than 4°C if all other sectors were to follow the same approach.
Highly insufficient< 4°C
World
NDCs with this rating fall outside of a country’s “fair share” range and are not at all consistent with holding warming to below 2°C let alone with the Paris Agreement’s stronger 1.5°C limit. If all government NDCs were in this range, warming would reach between 3°C and 4°C. For sectors, the rating indicates that the target is consistent with warming between 3°C and 4°C if all other sectors were to follow the same approach.
Insufficient< 3°C
World
NDCs with this rating are in the least stringent part of a country’s “fair share” range and not consistent with holding warming below 2°C let alone with the Paris Agreement’s stronger 1.5°C limit. If all government NDCs were in this range, warming would reach over 2°C and up to 3°C. For sectors, the rating indicates that the target is consistent with warming over 2°C and up to 3°C if all other sectors were to follow the same approach.
2°C Compatible< 2°C
World
NDCs with this rating are consistent with the 2009 Copenhagen 2°C goal and therefore fall within a country’s “fair share” range, but are not fully consistent with the Paris Agreement long term temperature goal. If all government NDCs were in this range, warming could be held below, but not well below, 2°C and still be too high to be consistent with the Paris Agreement 1.5°C limit. For sectors, the rating indicates that the target is consistent with holding warming below, but not well below, 2°C if all other sectors were to follow the same approach.
1.5°C Paris Agreement Compatible< 1.5°C
World
This rating indicates that a government’s NDCs in the most stringent part of its “fair share” range: it is consistent with the Paris Agreement’s 1.5°C limit. For sectors, the rating indicates that the target is consistent with the Paris Agreement’s 1.5°C limit.
Role model<< 1.5°C
World
This rating indicates that a government’s NDC is more ambitious than what is considered a “fair” contribution: it is more than consistent with the Paris Agreement’s 1.5°C limit. No “role model” rating has been developed for the sectors.

Fair share

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.
