Once considered a luxury, cooling has become essential for survival as global temperatures rise and cities experience record-breaking heatwaves. However, the globe is approaching a perilous paradox, according to the UN Environment Programme’s (UNEP) Cool Coalition: the very mechanisms intended to shield people from heat could exacerbate climate change. The newly released Global Cooling Watch 2025 report warns that global cooling demand is to triple by 2050, potentially doubling related emissions to 7.2 billion tonnes of CO₂ equivalent unless nations adopt sustainable, inclusive, and low-carbon cooling solutions.

“We cannot air-condition our way out of the heat crisis,” warned Inger Andersen, Executive Director of UNEP. Cooling needs to be economical, fair, and ecologically responsible. The results, presented at COP30 in Belém, Brazil, view cooling as a crucial infrastructure, on par with energy, water, and sanitation, and call for swift action to transform how the world stays cool.

What Does a Sustainable Cooling Pathway Look Like?

UNEP’s Sustainable Cooling Pathway outlines a plan that could reduce emissions by 64% and save $43 trillion in avoided electricity and system expenditures by the middle of the century, helping offset the climate costs of rising demand. Cooling-related emissions might drop by 97% and approach net zero when paired with rapid decarbonization of the electricity sector.

Three primary pillars are supporting this pathway:

• Passive Cooling Measures: Using shade, ventilation, reflective roofs, and green areas to lower indoor temperatures without using electricity is known as passive cooling.
• Low-Energy and Hybrid Systems: To reduce energy consumption, fans and energy-efficient air conditioners are combined.
• High-Efficiency Equipment: Accelerating the Kigali Amendment‘s global phase-down of HFC refrigerants.

When combined, these actions can help three billion more people, especially in the Global South, have access to sustainable cooling while easing the burden on already vulnerable electrical systems.

How Can Equity and Access Be Ensured in the Cooling Transition?

Currently, over 1 billion people lack adequate access to cooling; if nothing is done, this number is expected to increase to 1.5 billion by 2050. The growing gap between those who can afford heat protection and those who cannot is shown by the global cooling demand to triple by 2050.

As stated in the report:

• The most vulnerable groups include women, smallholder farmers, and the elderly, particularly in South Asia and Africa.
• The most significant improvements in comfort come from passive and low-energy cooling, which can reduce interior temperatures by up to 8°C and household energy use by at least 30%.
• To provide fair access, inclusive funding, and technology transfer are essential.

According to Somalia’s Minister of Environment and Climate Change, Bashir Mohamed Jama, “sustainable cooling is not a luxury — it’s a lifeline.” Somalia and other developing countries are striving to make cooling accessible, economical, and practical by participating in UNEP’s Beat the Heat campaign.

How Are Cities Leading the ‘Beat the Heat’ Movement?

Dense buildings trap heat and increase health concerns in urban areas, which are at the forefront of rising temperatures. The “Beat the Heat” implementation push, a global coalition of 187 cities from Rio de Janeiro to Nairobi dedicated to sustainable cooling action, was introduced at COP30 by UNEP and the Brazilian Presidency.

So far:

• The Global Cooling Pledge, which aims to reduce cooling-related emissions by 68% by 2050, has been signed by 72 nations.
• The Sustainable Cooling Pathway aligns with national policies in 54 nations.
• Green corridors, microparks, and reflective surfaces are being prioritized in cities like Fortaleza, Brazil, as they improve social well-being and cooling.

“Green corridors are not just cooling spaces – they are about equity, health, and livability,” stated Fortaleza Mayor Evandro Leitão. These regional efforts show how cooling can be used as a technique for both adaptation and mitigation of climate change.

What Policy Shifts Are Needed to Treat Cooling as a Public Good?

The research calls on governments to incorporate cooling and heat protection into housing, health, education, and urban planning as public goods. It suggests including sustainable cooling into building regulations, National Adaptation Plans (NAPs), and Nationally Determined Contributions (NDCs).

Key recommendations include:

• Urban greening and design: Reflective materials, water features, and trees can reduce city temperatures by up to 25%.
• Encouraging local governments: Cities should take the lead in implementing passive design and enforcing heat-resistant building standards.
• Innovation and data sharing: Singapore, for example, is providing its digital climate modeling tools to help other cities efficiently plan for and anticipate the effects of heat.

“We can’t keep treating heatwaves as isolated disasters,” stated Andersen of UNEP. Cooling must be incorporated into our economies and health systems, as these hazards are predictable and persistent.

This comparison shows that switching to sustainable cooling is both economically and environmentally sound, providing long-term savings and increased equity.

From Crisis Response to Systemic Cooling Governance

The UN stresses that as global cooling demand is to triple by 2050, nations must shift from crisis response to systemic governance. This entails investing in regional innovation, coordinating with decarbonization objectives, and institutionalizing cooling in climate adaptation.

This new way of thinking is embodied in the Brazilian COP30 program, Mutirão Contra o Calor Extremo (Collective Effort Against Extreme Heat). To ensure that cooling becomes a climate solution rather than a burden, the program focuses on integrating cooling solutions into city planning.

These days, cooling is a worldwide equality issue, a development challenge, and a public imperative. The global cooling demand to triple by 2050 is a warning and a roadmap: without swift action, cooling might exacerbate the heat catastrophe it seeks to address; with the correct response, it could become a pillar of a more secure and sustainable future.

Frequently Asked Questions (FAQs)

Q1. Why is it anticipated that demand for cooling would triple by 2050?

The demand for air conditioning is increasing due to urbanization, global population expansion, and rising temperatures, particularly in emerging nations. This will triple emissions and triple the world’s cooling needs in the absence of sustainable designs.

Q2. Describe passive cooling solutions and explain their significance.

For low-income areas with limited access to power, passive cooling techniques—such as shade trees, ventilation, and reflecting roofs—are essential because they naturally reduce temperatures without using energy.

Q3. What role can people play in sustainable cooling?

Adopting energy-efficient appliances, using natural ventilation, planting greenery around dwellings, and supporting neighborhood initiatives that boost urban greening and heat resilience are all actions people can take.
