The Paris Agreement collectively committed the countries to limit Global Warming to well below 2°C and pursue efforts to limit warming to 1.5°C above preindustrial levels. However, how much Global Warming by 2100 is each country’s climate pledge leading to, if all countries adopted the same national approach and ambition? This question is being tried answered for the world’s countries on the new website ‘paris-equity-check.org‘ (Pledged Warming Map). The underlying ‘Peer-reviewed study‘ is published November 2018 in Nature Communications.
The site says: “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?” Read ‘Ambition of pledges‘ and ‘The science‘.
The table below shows 155 countries’ 1) ‘Per capita Climate Debt‘ in 2017, accumulated since 2000 in ClimatePositions, 2) per capita Fossil CO2 Emissions 2016, and 3) the pledges estimated effect on Global Warming by 2100 (Pledged Warming Map).
