China's climate goal needs negative emissions tech

摘要

CHINA'S pledge to reach carbon neutrality by 2060 may depend on extracting greenhouse gases from the air at massive scales. President Xi Jinping announced the target in September at the UN general assembly, saying that China's aim was "to have CO_2 emissions peak before 2030". To do so would require significant use of negative emissions technologies, such as capturing carbon dioxide directly from the air and the planting of new forests, according to an analysis led by Shreekar Pradhan at the University of Virginia.
