Global Cooling Initiative
What is it?
Cooling is essential to modern life, from air conditioning in buildings to preserving food and managing data. It includes technologies like air conditioners and refrigerators as well as the use of refrigerants and their management. As global temperatures rise, efficient and affordable cooling solutions are crucial to keeping people healthy and safe, while reducing energy consumption and minimizing climate pollution for a sustainable future.
Why it Matters
Cooling is a defining issue of our time, with 4 billion people facing extreme heat by 2030. Access to cooling is vital for health, productivity, and economic development. But current cooling technologies operate far below best possible efficiency levels and also use refrigerants that are potent greenhouse gases and often leak from the equipment. By accelerating energy-efficient cooling, using eco-friendly refrigerants, and improving refrigerant lifecycle management, we can provide cooling for all without warming the planet.
What We’re Doing
The RMI-led Global Cooling Prize, concluded in 2021, demonstrated residential AC technologies with five times lower climate impact and dramatically lower operating costs. Now, through the Global Cooling Efficiency Accelerator, RMI and partners are shaping the market to commercialize these solutions. Additionally, we’re advancing research on life-cycle refrigerant management.
