Amid rising heatwaves and surging cooling demand, adopting sustainable cooling – with a robust deal with passive methods low-energy and hybrid cooling that mixes followers and air conditioners that eat little or no energy – might minimize greenhouse gasoline emissions, save trillions of {dollars} and increase life-saving cooling entry to those that want it, based on a brand new UN Setting Programme (UNEP) report.
Global Cooling Watch 2025, launched at present at COP30 in Belém, Brazil, finds that cooling demand might greater than triple by 2050 underneath enterprise as common, pushed by will increase in inhabitants and wealth, extra excessive warmth occasions and low-income households more and more having access to extra polluting and inefficient cooling.
This could virtually double cooling-related greenhouse gasoline emissions over 2022 ranges – pushing cooling emissions to an estimated 7.2 billion tons of CO2e by 2050 – regardless of efforts to enhance vitality effectivity, part down climate-warming refrigerants and overwhelm energy grids throughout peak load.
The report suggests adopting a ‘Sustainable Coling Pathway’, which might scale back emissions to 64 per cent – 2.6 billion tons of CO2e – under the degrees anticipated in 2050. When mixed with fast decarbonization of the worldwide energy sector, residual cooling emissions might fall to 97 per cent under business-as-usual ranges.
“As lethal warmth waves turn into extra common and excessive, entry to cooling have to be handled as important infrastructure alongside water, vitality and sanitation,” stated Inger Andersen, Government Director of UNEP.
“However we can’t air situation our manner out of the warmth disaster, which might drive greenhouse gasoline emissions larger and lift prices. Passive, vitality environment friendly and nature-based options can assist meet our rising cooling wants and maintain individuals, food-chains and economies protected from warmth as we pursue world local weather objectives. We have now no excuse: it’s time we beat the warmth”.
Sustainable Cooling Pathway
Printed by the UNEP-led Cool Coalition, the report is essentially the most complete evaluation so far of the quickly rising world demand for cooling and the necessity for climate-friendly options to the difficulty.
A Sustainable Cooling Pathway can present entry to house cooling or refrigeration, resilient buildings and concrete inexperienced areas to all – together with low-income and susceptible teams – akin to smallholder farmers, ladies and the aged – with out exacerbating the local weather disaster.
This Pathway combines passive cooling methods, low-energy and hybrid cooling that mixes followers and air conditioners, fast adoption of high-efficiency tools and accelerated phase-down of hydrofluorocarbon (HFC) refrigerants underneath the Kigali Modification.
Almost two-thirds of the emissions cuts obtainable come from passive and low-energy options, reinforcing the urgency of embedding them in nationwide insurance policies and concrete planning. Such options are additionally extremely inexpensive and demanding for enhancing entry to cooling for 3 billion extra individuals by 2050.
If adopted, the Pathway might save US$17 trillion in cumulative vitality prices via to 2050 and keep away from as much as US$26 trillion in grid funding via lowered electrical energy demand.
Beat the Warmth
These measures underpin the Mutirão Contra o Calor Extremo / Beat the Warmth implementation drive – a collective effort of led by the Brazil COP30 presidency and UNEP Cool Coalition – to localize the World Cooling Pledge and bridge gaps in coverage, finance and supply of warmth resilience and concrete cooling. Right now, over 185 cities from Rio de Janeiro to Jakarta to Nairobi and 83 companions have joined Beat the Warmth -alongside the 72 World Cooling Pledge signatories.
“Beat the Warmth is a type of initiatives that reveals that mutirão works, that means that individuals have to return collectively and work on what they perceive. And that’s what Beat the Warmth is all about. It raised a difficulty in an interesting manner that can deliver individuals collectively to take the time we have to fight local weather change,” stated Ambassador André Corrêa do Lago, COP30 President-Designate.
Progress being made, however uneven
Some 72 nations have joined the Global Cooling Pledge to scale back cooling-related emissions by 68 per cent by 2050 following this Sustainable Cooling Pathway. As of mid-2025, 29 international locations had established particular greenhouse gasoline discount targets for the cooling sector, with an extra 5 creating such targets.
In whole, 134 international locations have included cooling into their Nationally Decided Contributions (NDCs), Nationwide Adaptation Plans (NAPs), Lengthy-term Low Emission Improvement Methods (LT-LEDS), vitality plans, or different nationwide local weather methods.
Nonetheless, solely 54 international locations have complete insurance policies throughout all three precedence areas for cooling: passive cooling in constructing vitality codes, minimal vitality efficiency requirements, and refrigerant transition. An extra 78 international locations cowl two of those pillars, 40 cowl just one, and 20 have but to start.
The most important gaps are in African and Asia-Pacific international locations, the place a lot of the worldwide rise in demand for cooling will be anticipated.
The report points a collection of suggestions to extend motion, together with transferring from emergency response mode to proactive, multi-level governance on excessive warmth and cooling, treating warmth safety and cooling as a public good, and prioritizing passive and Nature-based Options– together with city design – to chop cooling masses, mitigate the city warmth island impact and scale back grid stress.

“As a World Cooling Pledge signatory, Singapore is taking concrete steps in the direction of Pledge implementation and is proud to assist the Beat the Warmth initiative by sharing our technical experience and expertise in sustainable cooling and concrete warmth resilience and offering platforms for international locations to change information and finest practices.
Singapore will deliver collectively World Cooling Pledge focal factors, policymakers and practitioners from world wide for a overview of Pledge progress and a deep-dive on sustainable cooling and warmth resilience options. Singapore will even share our technical capabilities from our Digital City Local weather Twin to empower cities globally to raised mannequin, predict, and mitigate city warmth. These concrete contributions to Beat the Warmth displays our dedication to advance sensible, inclusive options for a cooler and extra climate-resilient future”
Dr. J Jeyaranjan, Government Vice-Chairman, State Planning Fee, Authorities of Tamil Nadu
“From taking the pioneering step of declaring warmth as a state-specific catastrophe to creating Warmth Motion Plans for main cities, Tamil Nadu has established a complete mannequin for warmth governance.
By becoming a member of fingers with the worldwide neighborhood via the ‘Beat the Warmth’ initiative, we’ve the chance to study from various experiences whereas sharing our personal data-driven governance approaches. I consider this co-learning partnership will mutually profit all collaborating cities in turning into heat-resilient, inclusive, and climate-ready.”
H.E. Evandro Leitão – Mayor of Fortaleza, Brazil
“Fortaleza is placing nature on the coronary heart of local weather adaptation and mitigation. We’re dedicated to scaling inexperienced corridors and microparks that cool our metropolis and shield essentially the most susceptible. That is about fairness, well being, and livability—and thru Beat the Warmth we wish to share and study with cities in Brazil and worldwide to speed up this transformation.
