report title

Reveal the imbalance between global carbon removal responsibilities and capabilities

report summary

Under the framework of the Paris Agreement, countries have successively proposed carbon neutrality goals, but few countries have mentioned the carbon removal responsibilities required for carbon neutrality. We allocated the amount of carbon removal required for the global 1.5 ° C goal to 170 countries based on common but differentiated responsibilities, and compared the resulting fair carbon removal path with national carbon removal capabilities. It was found that in order to achieve the 1.5℃ target, carbon removal will account for about 4% of each country's emissions in 2030 and reach 100% around 2060, achieving carbon neutrality. However, there is a huge imbalance between countries 'carbon removal responsibilities and carbon removal capabilities: 25 countries do not have the appropriate environment in terms of soil and climatic conditions to implement carbon removal through traditional methods;71 countries lack the necessary geological storage capacity to safely store captured carbon dioxide. Over time, the potential for countries to achieve carbon removal will gradually diminish. A 10-year delay in action will cause the carbon removal capacity of 36 countries to be unable to meet their responsibilities, which will nearly triple the carbon removal quota gap in 2050 to 15 billion tons. China has significant potential for carbon removal and carbon sequestration. On the basis of meeting domestic demand, there are still about 5.7 billion tons of traditional carbon removal potential and up to 89.4 billion tons of carbon sequestration potential. There are broad opportunities for international cooperation and carbon removal trading.
