This elegant system, put together by Friends of the Earth EWNI and Jubilee South Asia Pacific Movement on Debt and Development, is based on the “responsibility and capacity index” analysis embodied in the Climate Equity Reference Calculator. Its map interface is very cool, and simple to use, for it presents only a single Equity Settings profile. This is, for the record, a “high equity” profile defined by the Strong 2C pathway, high progressivity settings (including a $50,000 luxury threshold), a 1850 historical responsibility start date, a 50/50 responsibility/capacity weighting and “capacity adjusted” domestic emissions.
