Climate agents: The next frontier of AI for a sustainable world?

A boom meets a crisis

The rapid rise of artificial intelligence (AI) agents marks a major shift in the digital landscape. These autonomous systems are already transforming how people work, consume, and interact. But their expansion coincides with another defining force of our century: the escalating climate crisis. Despite their power, agents are not yet designed with sustainability as a core purpose — a gap that could either accelerate ecological harm or unlock unprecedented progress toward resilience and equity.

Their appeal is clear: agents streamline decisions, reduce workloads, and scale operations – often with minimal human input. They promise faster responses to complex challenges, higher efficiency, and the ability to coordinate across multiple systems in real time. But this rapid expansion also invites critical reflection. The infrastructure that powers AI is energy-intensive, resource-hungry, and largely concentrated in the Global North. Without intervention, the growth of agents risks deepening ecological and social inequalities, especially in the Global South. Realizing the potential of AI agents for climate action requires robust governance that balances innovation with accountability.

As we face converging crises of climate change, biodiversity loss, and widening inequity, the key question has become: Why are AI agents not already designed with contributions to sustainability as a primary focus?

From labs to the mainstream

AI agents are autonomous systems that interpret their environment, make decisions, and act to achieve goals. Unlike traditional software, they adapt, learn, and interact with other systems in real time. They draw on techniques like machine learning (ML), natural language processing (NLP), or computer vision, enabling them to analyze data and act in real time. 

While the concept is decades old, the rise of generative AI unlocked agents’ ability to understand language, handle complex data, and operate in open-ended environments — sparking today’s rapid adoption. Companies are embedding them across industries, from customer service bots that resolve complex queries to supply chain agents that forecast demand and optimize logistics

Across industries, agents automate routine work, process vast datasets, and optimize decisions in real time. Beyond efficiency, their autonomy opens a new frontier: targeted applications for climate action.

Turning autonomy into climate action

Agents go beyond efficiency: across industries they already automate routine work, process vast datasets, and optimize decisions — and their autonomy opens a new frontier: targeted applications for climate action. While AI has been recognised as an enabler of sustainability — optimizing energy systems, improving agricultural yields, and supporting healthcare innovation — the agentic approach adds a shift. These systems are not just analytical tools; they can monitor, analyze, and act on climate-related data in real time.

According to Google and BCG, AI could help reduce global greenhouse gas emissions by 5 - 10% by 2030 – the equivalent of the annual emissions of the European Union. Agents can help make this possible by connecting disparate datasets, coordinating responses across sectors, and embedding climate priorities into everyday decisions. 

What makes agents especially powerful is their autonomy: rather than waiting for instructions, they can act proactively within defined boundaries. This capability is not abstract; it translates into practical applications across sectors with the greatest potential for climate action. Consider autonomous systems embedded across industries, continuously optimizing decisions through a sustainability lens:

• Monitoring & reporting

• Risk monitoring and early-warning agents could track climate-related hazards — from extreme weather to regulatory shifts — and issue alerts to industries or governments, helping coordinate logistics and limit damage

• Emissions agents could consolidate, verify, and standardize real-time emissions data across companies, cities, and nations, reducing the reporting gaps that undermine climate accountability

• Finance & innovation

• Green investment agents could evaluate opportunities based on both financial return and climate impact, accelerating the flow of capital into sustainable projects

• Sustainable innovation agents could guide R&D teams in designing low-impact products, simulating new materials, and ensuring compliance with environmental standards from the earliest stages

• Operations

• Circularity agents could identify waste streams and propose reuse or redesign pathways, linking local resource data with circular economy strategies

• Scope 3 transparency agents could track indirect emissions across suppliers and logistics networks, reshaping corporate supply chains — responsible for the majority of emissions

If developed and scaled responsibly, these climate-focused agents could reshape how businesses, governments, and communities respond to the climate crisis, embedding sustainability into every process and decision.

The hidden costs

AI agents hold enormous promise, but innovation at this scale is never free. Their rapid expansion brings environmental and social costs that must be acknowledged and managed if the technology is to fulfill its potential responsibly.

Environmental impacts

Training and running AI models demand vast amounts of energy, projected to reach 4.4% of global electricity by 2035. Cooling servers requires enormous water volumes — a single state-of-the-art training run can consume 700,000 liters. The carbon emissions of training one large model can rival the lifetime footprint of dozens of cars. These pressures are compounded by related impacts such as resource extraction for chips and batteries, and the growing tide of e-waste from short hardware lifecycles.

Social impacts

None of the world’s top 100 high-performance computing clusters are located in developing countries, and around 90% of leading AI publications originate in the Global North — leaving the Global South dependent on external solutions. This imbalance risks excluding local realities from climate models and limiting innovation where adaptation is most urgent. Job displacement, projected to affect up to 30% of workers, could further weaken vulnerable communities’ capacity to adapt to climate impacts. And algorithmic biases, inherited from skewed datasets, may distort environmental decision-making, reinforcing inequalities rather than reducing them.

Harnessing the power of AI agents means confronting these externalities head-on. With deliberate governance, ethical design, and sustainable infrastructure, innovation can drive progress without deepening inequality or environmental harm. The challenge is not whether to build AI agents, but how to build them responsibly. 

Yet risks are only half the story. To balance the ledger, we must also imagine the opposite trajectory — one where agents are harnessed as allies of climate resilience.

If agents served the planet

Looking ahead, scenario-building shows what climate-conscious agents could achieve if designed with sustainability at their core. 

Imagine agents continuously optimizing decisions through a carbon-budget lens and reshaping how societies act on climate.

What could the world look like if AI agents were fully harnessed for climate action? A global ecosystem where agents consolidate, verify, and report real-time emissions data from civil society, governments, and industries, leaving no gap for greenwashing. Autonomous systems optimizing every process and decision — from manufacturing and logistics to energy grids and urban planning.

Even global negotiations could be transformed. With agents providing real-time data, simulations, and accountability insights, policymakers could make faster, evidence-based decisions — shifting climate diplomacy from reactive to proactive.

The challenge is clear: agents could help build the systemic intelligence humanity needs for climate action, but without systemic, sustainable design, their potential could be lost — or even turn counterproductive.

Rules for resilience

Governance is the hinge between potential and peril. Whether agents serve climate goals will depend on the rules, standards, and human oversight we build today.

Design inclusively. Agents must operate transparently, equitably, and sustainably across all sectors.

Set binding standards. Policies should embed sustainability criteria into AI development — from energy-efficient algorithms to low-impact hardware and lifecycle rules.

Keep humans in the loop. Even autonomous agents need oversight to verify outputs, prevent unintended consequences, and ensure accountability, safety, and fairness.

Cooperate globally. Shared frameworks for climate AI can promote best practices, reduce inequalities in access, and encourage collaboration between governments, businesses, and civil society. Capacity-building in the Global South is particularly critical to ensure equitable participation.

By integrating these principles, we can unlock AI agents’ transformative potential while safeguarding both people and the planet. This is what it means to design with purpose: keeping planetary resilience at the center of innovation. These principles make the difference between agents as accelerators of extractivism, or as guardians of resilience.

Choosing the frontier

AI agents are no longer speculative — they’re here, powerful, and expanding rapidly. Their potential to accelerate climate action is immense: from optimizing energy systems and supply chains to guiding sustainable innovation and climate finance. Their autonomy makes them powerful — but only if guided by deliberate design, governance, and human oversight.

The path forward requires integrating sustainability into the core of AI agent development, promoting equitable access, and embedding humans in the loop to ensure accountability. By combining innovation, policy, and global cooperation, we can create a future where AI agents actively support climate resilience, transparency, and planetary health.

The next frontier is not technological but ethical: will agents accelerate extractivism, or will we design them as guardians of resilience? The answer will depend on choices we make today — choices that can align autonomous intelligence with planetary survival.
