Low GWP Refrigerants

October 9, 2023, 12:00 pm - 1:30 pm

Electrify Now is honored to have this webinar as part of the 6th annual Sustainable Building Week – a week devoted to decarbonizing our homes and buildings. Check out all events happening during this week here.

Refrigerants are used in many familiar products from refrigerators to air conditioners, automobiles and of course, heat pumps. They already play a crucial role in our lives and are becoming more important as we transition to the all electric future. Refrigerants are required in any heat pump and are the secret to their efficiency as they capture and move heat to condition our spaces and heat our water.

Currently, most refrigerants have a high global warming potential (GWP) which means that if they escape to the atmosphere they can have negative climate impacts. While heat pumps still produce vastly lower emissions than their fossil fuel counterparts even when considering refrigerant leakage, reducing the GWP of refrigerants could significantly curb the planet’s warming. The Kigali Amendment internationally and the Environmental Protection Agency’s AIM act in the US both seek to reduce the GWP of refrigerants over the coming years. This means that common refrigerants like R410A will be phased out and replaced by the next generation of lower GWP refrigerants .

Join us as we explore the world of refrigerants with our panel of experts. We will answer the following questions and more:

  • What is the current state of refrigerants used in heat pumps and other devices?
  • How much of these refrigerants are estimated to be leaking into the atmosphere?
  • What is the Kigali Amendment and the AIM act and what does it require?
  • What are the new refrigerants that are coming and when will they be phased in?
  • What are the estimated climate benefits of these new refrigerants?
  • What are the implications for manufacturers and for consumers?
