Construction of abatement cost curves: The case of F-gases [PDF]
Most of scientific research on Greenhouse Gases (GHG) focuses on CO2 emissions. But non-CO2 gases (mainly F-gases in the form of HFCs, PFCs, and SF6) are more potent at trapping heat within the atmosphere. Currently, F-gases constitute a small proportion
