Signals of the Pandemic Seen in Greenhouse Gas Levels at the Harvard-Tsinghua Observatory near Beijing?

May 11, 2020

The below figures show cumulative probability distributions of carbon dioxide (CO2) and methane (CH4), the two leading greenhouse gases, as measured in March of 2019 (red) and 2020 (green) at the Harvard-China Project’s joint observatory with Tsinghua University at Miyun, north of Beijing.

Study finds that as cities become wealthier, per capita emissions drop

China, the world’s largest carbon emitter today, may be on track to meet its emission goals up to a decade early, according to a recent study on the cover of Nature Sustainability led by researchers from Nanjing University in Nanjing, China, and Harvard University.

The research focuses the relationship between urban economic growth and CO2 emissions. Fifty cities...
