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.

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.

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.

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.

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.

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.

We rate Australia’s NDC target for 2030 “Insufficient”. The “Insufficient” rating indicates that Australia’s climate commitment in 2017 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 Australia’s approach, warming would reach over 2°C and up to 3°C. This means Australia’s climate commitment is at the least stringent end of what would be a fair share of global effort, and is not consistent with the Paris Agreement’s 1.5˚C limit, unless other countries make much deeper reductions and comparably greater effort.

The CAT ratings are based on climate commitments in NDCs. If the CAT were to rate Australia’s projected emissions levels in 2017 under current policies, we would rate Australia “Highly insufficient,” indicating that Australia’s current policies in 2017 are not consistent with holding warming to below 2°C, let alone limiting it to 1.5°Cas required under the Paris Agreement, and are instead consistent with warming between 3°C and 4°C: if all countries were to follow Australia’sapproach, warming could reach over 3°C and up to 4°C. This means Australia’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.
