Abstract
We propose that the Group of Twenty (G20) enhance voluntary collaboration on cooling. International cooperation for energy-efficient and sustainable cooling requires enhanced G20 joint leadership that strengthens existing initiatives, helps develop synergies, and addresses the new cooling challenges presented by the COVID-19 pandemic. Safer air conditioning systems and cold chains for vaccines are urgently needed. Stimulus measures can retrofit old buildings and equipment to boost efficient cooling while phasing out harmful refrigerants and promoting a circular economy. To be led by countries with the greatest interest, enhanced collaboration can pool together experiences and expertise enabling more effective policy coordination and impact.
