REEF x CCSI Present: The Refrigerant, Circularity, & Efficiency Nexus

​Join REEF and the Columbia Center on Sustainable Investment on May 19 at 12pm PT for an interactive Call to Comment exploring the HVAC nexus: an integrated framework connecting refrigerant transition, circularity, and energy efficiency. Grounded in CCSI’s recent report, this session invites participants to actively engage with the material through live polls, discussion prompts, and audience reflection woven throughout each section of the webinar.

​Together, we’ll examine how the HVAC sector can decarbonize the built environment while meeting growing heating and cooling demand through a transition to low-GWP, PFAS-free refrigerants, stronger refrigerant circularity practices (including recovery, reuse, and leakage prevention), and accelerated deployment of high-efficiency technologies like heat pumps.

​Rather than a traditional webinar, this event is designed as a collaborative learning experience—giving attendees the opportunity to weigh in on key questions, compare perspectives with peers, and contribute live commentary on the challenges and opportunities shaping HVAC transition planning. Participants will leave with a stronger understanding of why these three pillars function as a mutually reinforcing nexus, and how integrated transition plans can reduce emissions in practice, avoid stranded assets, and support long-term system performance.
