a and Uganda (b) as examples. The successive update of continuous allocations emissions allocations, here illustrated with the addition of a transition period starting 2015 (dashed red) and 2020 (red), rewards countries with insufficient Nationally Determined Contributions (NDCs) by decreasing the 2030 gap (gray dashed line) with the emissions allocation. Cumulatively over the transition period, the allocation difference with a discontinuous allocation (green area), here based on Approach 2, affects the additional effort, and possible climate finance, needed to align NDC with fair allocations.
