Paris Equity Check
The Paris Agreement includes bottom-up pledges and a top-down warming threshold. Under this setting where countries effectively choose their own fairness principle, Paris-Equity-Check.org presents scientifically peer-reviewed assessments the ambition of countries’ climate pledges (the Nationally Determined Contributions or NDCs) and address the question:
What is a fair and ambitious contribution to achieving the Paris Agreement?
Pledged warming map
The Pledged Warming Map provides an assessment of global warming when all countries follow the ambition of a given one. This warming assessment assumes a self-interested approach of equity where each country follows the least stringent of three equity concepts (historical responsibility, capacity to pay and equality). This warming assessment reconciles the bottom-up architecture of the Paris Agreement with its top-down warming threshold.
The Equity Map shows how ambitious are countries’ climate pledges under the Paris Agreement across five commonly discussed visions of equity. Concretely, a country can be considered ambitious from more perspectives, and potentially more ambitious, when its climate pledge aligns with multiple visions of equity.
