The way ahead for sustainable cooling

(Eco Business, 21 Feb 2023) With sustainable cooling added to the COP28 agenda, stakeholders need to examine what has already been done, what has not worked, and what must change.

The last eight years were the hottest on record. Almost 1 billion people are at high risk from extreme heat due to lack of cooling access - the vast majority living in Africa and Asia. 

The need to come up with cooling solutions has reached a critical point, yet ironically, conventional cooling methods such as air conditioning are responsible for over seven per cent of global greenhouse gas (GHG) emissions.

Last month, the United Nations Environment Programme (UNEP) announced the development of a Global Cooling Pledge and a “Cool COP Menu of Actions” will be prioritised at the COP28 climate talks in November.

Sustainable cooling strategies are imperative but meaningful progress has been hampered by a range of obstacles.

What is sustainable cooling?

Sustainable cooling refers to the efficient and climate-friendly lowering of ambient temperatures and refrigeration. It can be achieved in several ways, such as lowering the energy consumption of cooling solutions, by utilising environmentally-friendly refrigerants, and through building design.
