The 'HCFC adder' in the Kigali Amendment baseline calculation

Report
A problematic feature of the Kigali Amendment baseline is the ‘HCFC adder’. Developing countries can add 65% of the HCFCs consumed in 2009-2010 to the actual HFC consumption in the baseline period. However, many developing countries have reduced HCFC consumption much faster due to financial support from the MLF. The countries with a strong HCFC reduction therefore get a severely overestimated Kigali Amendment baseline. This paper discusses baseline definitions.
