Nature – Lamboll et al. (2023): Assessing the size and uncertainty of remaining carbon budgets

The remaining carbon budget (RCB), the net amount of CO₂ humans can still emit without exceeding a chosen global warming limit, is often used to evaluate political action against the goals of the Paris Agreement. RCB estimates for 1.5 °C are small, and minor changes in their calculation can therefore result in large relative adjustments. Here, the authors evaluate recent RCB assessments by the IPCC and present more recent data, calculation refinements and robustness checks that increase confidence in them.
