An unprecedentedly broad and diverse coalition of global civil society organizations and social movements (see list here) has just released a joint assessment of countries' INDC-based mitigation pledges.
This assessment is done with eyes towards both adequacy and equity. Fundamentally, it asks what the various INDCs add up to in relation to a 1.5C / 2C degree goal, and if each country pledging to its fair share of the necessary mitigation action, based on its historical emissions and its capacity to act. When it comes to public mitigation finance, adaptation, and loss & damage, the assessment restricts itself to estimating total global needs.
Technically, the Civil Society Review draws upon the analysis and modeling of the Climate Equity Reference Project. It defines "fair shares" by way of a transparent range of “equity settings” that was agreed within the coalition. On the adequacy side, it is referenced to a challenging global mitigation pathway that represent a widely used distillation of the most stringent category of pathways in the IPCC scenario database.
Importantly, the point of the Civil Society Review is not to argue that countries should only do their fair shares. Rather, it seeks to identify which countries are offering to do their fair share, which need to do more to meet their fair share, and which must be supported to do even more than their fair share if the world is to reach a below 2C or even 1.5C pathway.
