Our findings show that the annual average CO2 concentrations will still increase through this year, even though emissions are reducing. Across the whole year, we estimate CO2 levels will rise by 2.48 parts per million (ppm). This increase is 0.32ppm smaller than if there had been no lockdown – equivalent to 11% of the expected rise.
