Regular reminder that it is an ESTIMATE of emissions across an enormous variety of industries, businesses and individuals over the whole year. A real factual and measurable metric is not some calculated rate of change of a value, but a measure of a value itself - in this case an amount of CO2 in the atmosphere.
Go to https://keelingcurve.ucsd.edu/, open "Full record" and see an objective and factual data (and not some politically motivated estimates) - amount of actually emitted gas is increasing, and the rate of increase is accelerating both for lowest points and highest points.
