![]() The findings highlight the scale of the impact that Covid-19 has had on the world’s economies. This year’s study, published in Earth System Science Data, uses four different methods to assess regional and global emissions across the world. The provisional estimate of CO2 emissions in 2020 is the GCP’s 15th in an annual series of “global carbon budgets” produced by an international group of scientists. What is the impact of Covid on 2020’s CO2 emissions? While a drop in emissions in a single year will not slow the pace of global warming, the researchers say, there is a “unique opportunity” to secure long-term emissions cuts by following an economic recovery “aligned with tackling climate change”. This will see atmospheric CO2 levels increase to an annual average of 412 parts per million – 48% higher than before the Industrial Revolution. This annual decline is the largest absolute drop in emissions ever recorded, the researchers say, and the largest relative fall since the second world war.įossil CO2 emissions have fallen in all the world’s biggest emitters, the study estimates – including by 12% in the US, 11% in the EU, 9% in India and 1.7% in China.Ĭombined with the impacts of land-use change, human-caused CO2 emissions this year will total 40GtCO2, the estimates suggest. The latest estimates from the Global Carbon Project (GCP) suggest that these emissions will clock in at 34bn tonnes of CO2 (GtCO2) this year – a fall of 2.4GtCO2 compared to 2019. Global carbon dioxide (CO2) emissions from fossil fuel and industry are expected to drop by 7% in 2020, new analysis shows, as economies around the world feel the effects of Covid-19 lockdowns.
