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 multi-equity map currently only assesses the ambition of countries’ first NDC.
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.
