As global temperatures rise, demand for cooling is surging and with it, so are emissions. According to the World Economic Forum (2023), cooling equipment already accounts for about 7% of global greenhouse gas emissions, and without urgent intervention, those emissions are expected to triple by 2050.
At the heart of the issue lies a clear paradox: we cool to cope with the heat, but the way we cool is heating the planet even more.
The good news? Sustainable cooling solutions are already here. With better technology, cleaner systems, and smarter design, they offer a way to reduce harm, save energy, and help slow climate change.
Here are seven ways sustainable cooling is making a real difference:
1. Cuts Energy Use and Emissions
Cooling is one of the most energy-intensive activities in buildings and industry. Older systems often run inefficiently, leading to high electricity use and preventable carbon emissions.
According to the UNEP, improving the efficiency of cooling equipment alone could deliver 30% of the total energy savings needed to meet global climate targets.
By switching to systems that use less power—like inverter-based units or smart, demand-responsive cooling—we can cut energy use significantly without compromising comfort.
2. Breaks the Cooling–Warming Cycle
Here’s the problem: the hotter it gets, the more we rely on air conditioning. But most traditional ACs use a lot of electricity and release gases that trap heat in the atmosphere. This creates a dangerous cycle—we cool down, but in doing so, we warm the planet even more.
Sustainable cooling helps break that cycle. It uses cleaner refrigerants, energy-efficient systems, and smarter designs to reduce the harm caused by cooling. So even as demand grows, the impact on the planet doesn’t have to.
The UN Environment Programme estimates that these improvements could cut cooling-related emissions by up to 96% by 2050 (UNEP, 2023).
3. Replaces Harmful Refrigerants
Traditional cooling systems often rely on hydrofluorocarbons (HFCs) which are synthetic gases that can trap the same amount of heat as 12,400 kg (Environmental and Energy Study Institute). Even small leaks during maintenance or disposal can have a large climate impact.
Today’s sustainable systems are shifting toward lower-impact alternatives, including natural refrigerants like CO₂, ammonia, and hydrofluoroolefins (HFOs), which cool efficiently with much lower warming potential.
According to the Kigali Amendment Report (2019), reducing HFCs could avoid up to 0.4°C of global warming by the end of the century.
4. Reduces Cooling Demand at the Source
Another way to cut emissions is to reduce the need for cooling in the first place. That’s where passive and nature-based strategies come in.
Good building insulation, cross-ventilation, reflective materials, and smart layout can help maintain indoor comfort without relying heavily on ACs. Meanwhile, urban greenery—like trees, shaded walkways, and green rooftops—can lower outdoor temperatures.
The UNEP’s ‘Beating the Heat: A Sustainable Cooling Handbook for Cities,’ (2021) reports that these approaches can reduce city temperatures by up to 4°C, easing the pressure on mechanical cooling and the energy grid.
5. Cuts Emissions from Food and Medical Cold Chains
Cooling isn’t just about comfort—it’s essential for preserving food and medicines. But cold chains used to store and transport these goods are often powered by fossil fuels and built with leak-prone systems.
Sustainable Food Cold Chains report by UNEP shows that food-related cold chains contribute significantly to emissions and food loss—especially when systems are outdated or inefficient.
Sustainable cold chains use efficient, low-GWP systems and off-grid-compatible solutions to cut emissions while protecting critical goods, even in remote or high-temperature areas.
6. Fuels Innovation in Climate-Friendly Cooling
The shift to sustainable cooling is also sparking new innovation. From solar-powered chillers to smart temperature controls, cooling is evolving fast.
According to the Frontiers in Sustainable Cooling Report (2021), combining modern cooling with renewable energy—like solar panels—can dramatically lower total emissions and make cooling more widely accessible.
These innovations are not only lowering the climate impact of cooling, they’re also making it cheaper, smaller, and more efficient across different use cases and regions.
7. Delivers System-Wide Economic Benefits
Finally, sustainable cooling doesn’t just help the planet—it makes financial sense.
By using less electricity, avoiding system breakdowns, and cutting back on refrigerant losses, these systems reduce costs over their lifetime. They also reduce the need for expensive energy infrastructure upgrades as cooling demand grows.
The UNEP Cooling for All: Needs-Based Assessment (2023) estimates that switching to sustainable cooling could save end-users nearly $1 trillion annually, while helping the power sector avoid up to $5 trillion in infrastructure and fuel costs by 2050.
Aligns with Global Sustainability Goals
Sustainable cooling doesn’t exist in isolation, it’s deeply tied to global frameworks aimed at tackling the climate crisis. For instance, it supports at least four UN Sustainable Development Goals (SDGs):
- Goal 3: Good Health and Well-Being
- Goal 7: Affordable and Clean Energy
- Goal 10: Reduced Inequalities (through equitable access to cooling)
- Goal 13: Climate Action
More than 1.2 billion people around the world lack access to adequate cooling—putting their health, livelihoods, and food security at risk (Sustainable Energy for All, 2020). Making cooling more accessible and efficient is key to closing this gap—without creating more emissions in the process.
In this way, sustainable cooling doesn’t just reduce emissions—it helps build a more equitable, climate-resilient future.
The Future of Cooling Is Already Here
Sustainable cooling can cut emissions, reduce energy demand, replace harmful refrigerants, and even spark system-wide innovation. It’s a practical, proven way to slow climate change—and one we can’t afford to overlook.
What’s needed now is action. The kind that moves from theory to practice, from global goals to everyday decisions.
Circolife helps bridge that gap. By offering energy efficient cooling on subscription, we make it easier for businesses to adopt these solutions—without the complexity or cost of doing it alone.
Because solving the climate crisis means rethinking the systems we rely on. And cooling is one of the biggest, most powerful levers we have.
