Study: National climate pledges and the resulting Global Warming by 2100 (The Pledged Warming Map)

Study: National climate pledges and the resulting Global Warming by 2100 (The Pledged Warming Map)

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).

IPCC Report: Limiting Global Warming to 1.5ºC requires 45% CO2 reductions by 2030 compared to 2010 – and zero emissions by 2050 (but which countries are to reduce how much per capita?)

IPCC Report: Limiting Global Warming to 1.5ºC requires 45% CO2 reductions by 2030 compared to 2010 – and zero emissions by 2050 (but which countries are to reduce how much per capita?)

The IPCC Report ‘Global Warming of 1.5°C‘ released October 2018, finds that limiting global warming to 1.5°C would require reductions of global human-caused CO2 Emissions (carbon dioxide) of 45% by 2030 compared to 2010, and reach zero emissions around 2050¹.

However, since global Fossil CO2 Emissions increased 6.4% between 2010 and 2016, and the world population is expected to grow 1.2% annually the years to come, the required 45% global CO2 reductions by 2030, is equivalent to 53% reduction per capita by 2030 compared to 2016, or in only 14 years. In other words, an average world citizen must cut Fossil CO2 Emissions from 4.8 tons in 2016 to around 2.3 tons by 2030 and zero by 2050 (if limiting global warming to 1.5°C). Note that forest cover growth, removing CO2 from the air, etc. can substitute Fossil CO2 reductions in the IPCC scenarios².
