Satellite-based estimates of decline and rebound in China's CO emissions during COVID-19 pandemic

Bo Zheng, Guannan Geng, Philippe Ciais +13

Changes in CO emissions during the COVID-19 pandemic have been estimated from indicators on activities like transportation and electricity generation. Here, we instead use sate…

Low latency carbon budget analysis reveals a large decline of the land carbon sink in 2023

Piyu Ke, Philippe Ciais, Stephen Sitch +13

In 2023, the CO2 growth rate was 3.37 +/- 0.11 ppm at Mauna Loa, 86% above the previous year, and hitting a record high since observations began in 1958, while global fossil fuel C…

Carbon Monitor: a near-real-time daily dataset of global CO2 emission from fossil fuel and cement production

Zhu Liu, Philippe Ciais, Zhu Deng +15

We constructed a near-real-time daily CO2 emission dataset, namely the Carbon Monitor, to monitor the variations of CO2 emissions from fossil fuel combustion and cement production…

Low latency global carbon budget reveals a continuous decline of the land carbon sink during the 2023/24 El Nino event

Piyu Ke, Philippe Ciais, Yitong Yao +28

The high growth rate of atmospheric CO2 in 2023 was found to be caused by a severe reduction of the global net land carbon sink. Here we update the global CO2 budget from January 1…

COVID-19 causes record decline in global CO2 emissions

Zhu Liu, Philippe Ciais, Zhu Deng +37

The considerable cessation of human activities during the COVID-19 pandemic has affected global energy use and CO2 emissions. Here we show the unprecedented decrease in global foss…
