HFC Background Science Video - CCAC Science Policy Dialogue
A Q&A with CCAC Scientists, A.R. Ravishankara and Pallav Purohit, as they answer questions about the latest HFC science, impacts and opportunities to mitigate emissions and help put the world on a safe pathway to 1.5°C.
1. What are the major sources of HFC emissions globally, and what are the main uses of HFCs and their drivers today and into the future?
2. What would have been the contribution of HFC emissions to climate change without the 2016 Kigali Amendment and how much mitigation is it expected to achieve in the next two decades?
3. Are HFCs still an issue now that we have the Kigali Amendment?
4. How substantial are indirect emissions of CO2 from energy production compared to direct HFC emissions from refrigerant and cooling equipment?
5. How much additional mitigation is possible by moving from the Kigali scenario to a maximum technically feasible scenario of mitigation, and what implications does this have for the climate?
6. What are the implications for air pollution emissions mitigation by moving to full compliance with the Kigali phasedown in parallel with the application of technically available efficient technologies?
7. Where does HFC-23, which is a byproduct of HCFC production, fit in this broader picture of HFC management?
