Remaining Carbon Budget

The IPCC defines the world’s remaining carbon budget as the cumulative net global anthropogenic CO₂ emissions to the time that emissions reach net zero that would result in limiting global warming to a given level, accounting for the impact of other anthropogenic emissions. In other words, it allows us to calculate how much CO₂ can still be released to limit global warming to a maximum of 1.5°C and 2°C, respectively. Currently, emissions equivalent to 42 gigatonnes (Gt) of CO₂ are released globally every year. The following MCC Carbon Clock shows that time is ticking very fast and that we urgently would need to decarbonize our global supply chains.
