CCAC Science Policy Dialogue - HFCs


The CCAC's Scientific Advisory Panel will host its second virtual Science Policy Dialogue on Monday, 28 September 2020, under the theme "Catalyzing 2030 Mitigation Ambition – HFCs."

This event will bring together scientists, policymakers, practitioners, and regulators to review HFC emissions reduction potentials and the ways HFC mitigation can be leveraged to drive ambitious action this decade.

Discussions will focus on the opportunities and barriers for mitigating global emissions of HFCs consistent with a 1.5C pathway by 2030.

This is the second dialogue organized by the CCAC's Scientific Advisory Panel in 2020. The first dialogue, on 22 June, focused on mitigation opportunities for methane.

14:30 | Welcome and Instructions

  • Helena Molin-Valdes, Head of the CCAC Secretariat

14:35 | Session 1 – Equipment in Use and Avoiding the Need for Cooling: Opportunities and Challenges

This session will overview expected achievement in mitigation through the Kigali Amendment, in comparison with the mitigation expected in 1.5°C consistent scenarios under the Paris Agreement. It will also assess additional potential mitigation and benefits which could be achieved beyond the current level of KA ambition and discuss the opportunities for the CCAC to support greater ambition.

  • Durwood Zaelke, Institute for Governance & Sustainable Development (Moderator)
  • Pallav Purohit, Research Scholar, International Institute for Applied Systems Analysis (IIASA)
  • Engr. Idris Abdullahi, Assistant Director and National Ozone Officer, Federal Ministry of Environment, Nigeria
  • Helen Walter-Terrinoni, Vice President Regulatory Affairs, AHRI

  • Clarisse Durand, Policy Advisor,Ministry for an Ecological Transition, France
  • Philippe Chemouny, Manager, Montreal Protocol, Environment and Climate Change Canada
  • Ajiniyaz Reimov, Programme and Research Analyst, Montreal Protocol Unit, UNDP
  • Omar Abdelaziz, Assistant Professor, American University in Cairo, Egypt

15:35 | Session 2 – Life Cycle Management (refrigerant end of life)

This session will highlight on the current state of management of refrigerants at the end of life, opportunities for mitigation within the 2030 timeframe, and how the CCAC can support greater ambition within the 2030 timeframe. This session is co-organized with the Ministry of the Environment, Japan, which launched the Initiative on Fluorocarbons Life Cycle Management (IFL) at COP25 in 2019.

  • Bassam Elassaad, Senior Expert Member, Montreal Protocol Technology and Economics Assessment Panel (TEAP) (moderator)
  • Dr. Noboru Kagawa, National Defense Academy of Japan
  • Ms. Asako Toyozumi, Director, Office of Fluorocarbons Control Policy, Ministry of the Environment, Japan

  • Ms. Ratinasari, Directorate of GHG Inventory and Monitoring, Reporting, and Verification, Ministry of Environment and Forestry, Indonesia

  • Ole Kristian Kvissel, Senior Adviser, Section for Climate Science, Norwegian Environment Agency
  • Irene Papst, HEAT International
  • Asmau Jibril, Overseeing Head, Mitigation Division, Federal Ministry of Environment, Nigeria
  • Mr. Tetsuji Okada, President, Japan Refrigeration and Air Conditioning Industry Association (JRAIA)

16:35 | Session 3 – Cross Cutting Opportunities and Challenges

This session will focus on opportunities for enhancing near-term HFC mitigation through cross-cutting action, such as by focusing on cold food chains and by focusing on parallel energy efficiency improvements.

  • Natalia Alekseeva, Team Leader for National Climate Change Action, FAO (moderator)
  • A.R. Ravishankara, Colorado State University

  • Niurka Carvajal, Ministry of Environment and Natural Resources, Dominican Republic

  • Zerin Osho, Project Expert, International Solar Alliance

  • Patrick Blake, Programme Officer, UNEP

  • Kevin Fay, Executive Director, Alliance for Responsible Atmospheric Policy


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?
