UNITED NATIONS – The delegates on Tuesday are weighing a paradox at the heart of climate innovation: how to harness powerful tools like artificial intelligence and advanced cooling systems without deepening the very crisis they aim to solve as the planet heats up, so does the race for smarter, cleaner technology at COP30 in Belém, Brazil.
AI is helping farmers predict droughts and manage crops more efficiently, but the environmental cost of training large models and running vast data centres is raising alarms, the COP3- stated.
The cooling seen as a luxury, a survival need in many parts of the world – remains one of the fastest-growing sources of greenhouse gas emissions.
From passive cooling architecture to solar-powered refrigeration, sustainable alternatives are gaining traction but scaling them up is another story.
Technology Implementation Programme, is at the centre of the negotiations at COP30 is the long-delayed a blueprint for getting life-saving innovations into the hands of those who need them most.
The progress is slow. Intellectual property rules, commercial restrictions, and financing hurdles continue to block access for developing countries – even as the urgency grows.
COP30 Executive Director Ana Toni said that she had joined discussions on technological innovations that could accelerate climate solutions from flood warning systems and methane-monitoring satellites to breakthroughs in energy efficiency.
The launch of the Beat the Heat Implementation Drive, a joint push by Brazil’s COP30 Presidency, the UN Environment Programme and partners in the Cool Coalition.
The initiative is to make cooling more accessible and less polluting in a world where deadly heat waves are becoming the norm.
The cooling demand is expected to triple by 2050, driven by rising temperatures, growing populations, and expanding access to inefficient cooling systems. Without intervention, emissions from cooling could nearly double, overwhelming power grids and pushing climate goals out of reach.
UNEP’s new Global Cooling Watch 2025 report warned that business-as-usual cooling could generate 7.2 billion tonnes of CO₂-equivalent emissions by mid-century.
The Beat the Heat drive promotes a Sustainable Cooling Pathway a mix of passive design, nature-based solutions, and clean technologies that can slash emissions by up to 97 per cent when paired with rapid decarbonization.
It’s not about air conditioners: cool roofs, urban green spaces, and low-energy systems are central to the plan.
Two-thirds of the potential emissions cuts come from passive and low-energy solutions, many of which are affordable and scalable.
UNEP Executive Director Inger Andersen said cooling must be treated as essential infrastructure, alongside water and energy,”. “But we cannot air condition our way out of the heat crisis.”
Over 185 cities from Rio to Nairobi have signed on to Beat the Heat, with 72 countries backing the Global Cooling Pledge.
The initiative is designed to bridge gaps in finance, policy, and delivery, especially for vulnerable communities on the frontlines of climate change.
The artificial intelligence isn’t part of the formal negotiations at COP30, it’s gaining traction in the Action Agenda a platform designed to mobilize voluntary climate action from civil society, businesses, investors, cities, and states.
These actors may not sign treaties, but they’re essential to turning climate commitments into reality.
Brazil’s Government is mapping successful examples of how AI can support climate resilience, a growing trend among other UN Member States.
Lao People’s Democratic Republic, where researcher Alisa Luangrath developed an AI-powered irrigation system in Savannakhet Province, a region hit hard by water shortages and climate stress.
She was named the 2025 winner of the UNFCCC “AI for Climate Action” Award.
Ms. Luangrath explained that the system integrates soil moisture sensors, groundwater monitors, and meteorological data with AI-driven analytics. The technology processes this information to forecast land conditions, water availability, and risks of flooding or heat extremes. Farmers receive real-time updates via a mobile app, helping them plan planting and irrigation cycles more efficiently.
She told that she hopes her participation in COP30 will help forge partnerships to bring the innovation to other countries and communities vulnerable to climate shocks.
All AI models and data tools developed under her project will be made available under open-source licenses, ensuring free access for reuse and improvement.
But as AI use expands, so does concern over its environmental footprint.
Luã Cruz, Coordinator for Telecommunications and Digital Rights at Brazil’s Consumer Defense Institute warned that even everyday digital activities from mobile phone use to online interactions rely on massive data centres.
“These facilities consume vast amounts of energy and water for cooling, occupy extensive land areas, and require significant mineral extraction for their electronic components,” he explained.
Mr. Cruz added that many data centres “ignore planetary boundaries, seeking locations with minimal environmental regulation and generous tax exemptions.”
Brazil and several other countries, is racing to attract such facilities a move Mr. Cruz believes could worsen water stress.
He pointed to the Netherlands’ moratorium on new data centres, and the removal of installations in Chile and Uruguay that exacerbated local droughts.
Idec is involved in two legal cases in Brazil. One concerns a planned TikTok data centre in Caucaia, Ceará, near Indigenous territory.
Other involves a proposed facility in Eldorado do Sul, Rio Grande do Sul a city that was more than 80 per cent submerged after last year’s devastating floods.
