China News Service, Beijing, October 25 (Liu Wenwen) On the 25th, the China Carbon Accounting Data Team led by Guan Dabo, a professor at the Department of Earth System Science of Tsinghua University, put forward a new view on global climate change emission reduction at a press conference, that is, small and medium-sized emerging emissions. Economies (hereinafter referred to as "emerging emitting economies") will be the main contributors to the increase in global carbon dioxide emissions in the future.
The "Emerging Economies Carbon Dioxide Emissions Report 2022" (hereinafter referred to as the "Report") compiled by the team was released at a press conference held on the same day.
The report adopts international authoritative accounting methods to build a unified, transparent and scientific accounting system, and forms the carbon dioxide emission inventory of 50 emerging economies around the world from 2010 to 2019.
The report shows that the fossil energy-related carbon emissions of the 50 emerging economies increased from 6.3Gt (1Gt=1 billion tons) in 2010 to 7.8Gt in 2019, with an average annual growth rate of 3.9%.
Among them, India's fossil energy carbon emissions increased from 1.4Gt to 2.3Gt (an annual increase of 6.0%), and Russia's fossil energy carbon emissions in 2019 remained at 1.5Gt (an annual increase of about 0.3%).
Fossil energy carbon emissions in the other 48 countries rose from 3.5Gt to 3.9Gt during this period (an increase of 1.3% per annum), a trend associated with high carbon energy use and ongoing industrialization processes, both effectively stimulating economic growth and increasing corresponding carbon dioxide emissions.
The team's latest research results show that between 2010 and 2018, the annual emission growth rate of more than 50 emerging emitting economies was higher than the global average. Although the emissions of each economy were less than 1% of the total global emissions, the overall emissions were 1.6 times that of India.
The infrastructure construction driven by the future industrialization process of these countries will lead to continuous growth of carbon emissions, which undoubtedly poses a serious challenge to the goal of controlling the temperature rise within 1.5 degrees Celsius by the end of the 21st century.
The team found that if the global temperature target of 1.5 degrees Celsius is to be achieved, and there is enough room for carbon emissions in emerging emitting economies, other countries need to reduce carbon emissions by 7.2% per year. However, between 2010-2018, the European Union and the United States The average annual decline rate of carbon emissions in China is only 1.4% and 0.9% respectively.
Guan Dabo said that this has put forward more urgent requirements for the emission reduction of developed countries mainly in Europe and the United States.
On the one hand, developed countries should provide economic and technical support to emerging emitting economies; on the other hand, they need to strengthen their own emission reduction targets to make room for emissions for emerging emitting economies.
