Each year, one-third of the total food for human consumption is either lost or wasted even as millions worldwide experience food insecurity. Similarly, over 25 percent of vaccines are wasted each year while millions die from vaccine-preventable illnesses Sustainable cold chain infrastructure can significantly reduce post-harvest food loss and vaccine wastage and deliver social and climate benefits. However, acknowledging the need for cold storage alone does not ensure food security or access to vaccines, and must be supported by policies and resources, including technologies. Cooperation among G20 countries on cold chains can help coordinate the policies and resources necessary to advance food security, public health, and climate change mitigation.

Heating and cooling demand for space conditioning and refrigeration accounts for around a fifth of global final energy consumption. Climate change, urbanization, and economic development have tripled electricity demand for cooling alone since the 1990s, with the majority coming from the use of inefficient cooling equipment, which burdens electricity grids, especially during peak hours. It is imperative to address the energy required to provide cooling. The Kigali Amendment to the Montreal Protocol addresses these needs by setting ambitious global targets to phase down refrigerants with high global warming potential while improving energy efficiency. Integrating energy efficiency and the refrigerant transition will contribute to economic security, well-being, energy access and security, and sustainability among the G20 countries.
