Study: Fossil fuel CO2 emissions reached max daily decline of 17% in April

Green Car Congress

The analysis, published in Nature Climate Change , was conducted by researchers from the University of East Anglia, Stanford University, the CICERO Center for International Climate Research and CSIRO as part of the Global Carbon Project. Estimates were then compared against daily emissions data from the same period in 2019.
