The Fair Mitigation Finance Explorer is the webapp that accompanies our Science paper on fairness in global mitigation investments (Pachauri, Pelz et al., 2022). The paper argues that least-cost abatement shows where mitigation should happen, not who should pay for it. The tool lets users work through the second question themselves, making their own value judgements rather than taking our indicator choices on trust.
Users choose one indicator for each of three equity considerations and weight them. Responsibility is cumulative CO2 from fossil fuels and industry over 1850–2019 or 1990–2019. Capability is per capita GDP or per capita capital stock in 2019. Need is multidimensional deprivation in decent living standards, or acute multi-sector climate risk in 2030. The weights are normalised, and the resulting fair-share allocation is applied to regional cost-effective investment needs for 2020–2030. These come from Figure TS.25 of the IPCC AR6 WGIII Technical Summary, at either the lower or upper bound. Where a region's fair-share contribution exceeds its own need, the difference is an interregional outflow; where it falls short, the gap is met by inflows. The dashboard shows both the allocation and the transfers it implies across the ten IPCC regions.
Built in 2022 as an R Shiny app, it has since been rebuilt as a static site with the same data and arithmetic. It is preserved as a legacy tool within the paper's replication archive.
