Thus, the concept of an emissions budget is very useful to get the message across that the amount of CO2 that we can still emit in total (not per year) is limited if we want to stabilise global temperature at a given level, so any delay in reducing emissions can be detrimental — especially if we cross tipping points in the climate system, e.g trigger the complete loss of the Greenland Ice Sheet.
