Swiss researchers pioneer new approach combining satellite data and AI to provide more accurate greenhouse gas emission measurements and strengthen climate action efforts.

"AI can process a lot of information about what the specific GHG emissions are, where they come from and their impact on climate change."
"AI can help us to interpret this data and give us additional context."
The era of estimating climate damage is over; the era of verification has begun. For years, the Paris Agreement has relied on a sluggish, resource-heavy system where nations self-report their greenhouse gas (GHG) emissions based on theoretical calculations. This outdated method is fraught with uncertainty and gaps. Now, Swiss researchers are shattering this status quo. By fusing cutting-edge satellite imagery with advanced Artificial Intelligence, scientists at the Swiss Federal Laboratories for Materials and Technology (Empa) are pioneering a method to measure the planet's pulse with unprecedented precision.
This is not merely about watching the weather. It is a fundamental shift in how humanity holds itself accountable. Gerrit Kuhlmann and his team at Empa are developing systems that bypass bureaucratic estimates to provide hard, undeniable data. As the climate crisis accelerates, this Swiss-led initiative offers a critical tool for transparency, promising to transform vague national reports into verifiable, real-time climate action.
Raw data is useless without the intelligence to interpret it. That is where the new Swiss approach changes the game. "AI can process a lot of information about what the specific GHG emissions are, where they come from and their impact on climate change," asserts Gerrit Kuhlmann. The integration of AI allows researchers to do more than just map general atmospheric trends; they can now zoom in with lethal accuracy to identify specific polluters.
The technology is designed to detect carbon dioxide, methane, and nitrogen dioxide (NO2) with such granularity that it can pinpoint individual hotspots—be it a sprawling oil facility, a gas leak, or a coal-fired power plant. This capability turns satellites into orbital detectives, capable of validating or debunking national policies in near real-time. By feeding satellite observations into complex AI models, Empa is creating a system where problematic emissions can no longer hide behind averages or aggregate data.
The skies above us are becoming crowded, and the planet is better for it. We are witnessing a staggering surge in orbital infrastructure. In 2013, there were roughly 200 Earth-observing satellites circling the globe. By 2023, that number had skyrocketed to nearly 1,200—an explosive 500% increase in just one decade. Today, these vigilant eyes in the sky represent almost 20% of all orbiting satellites.
This is a fiercely competitive space race focused on planetary health. Titans of the private sector, including SpaceX, Blue Origin, and Planet Labs, are jostling for dominance, launching fleets of small satellites that push the boundaries of imaging resolution. Just this January, Blue Origin’s massive New Glenn rocket roared into the Florida skies, signaling the next chapter in heavy-lift capabilities. This constellation of technology ensures that no corner of the Earth remains unmonitored, providing the raw feed that Swiss scientists need to power their AI models.
The convergence of space tech and climate science is not just an environmental imperative; it is a massive economic engine. The World Economic Forum projects that by 2030, the Earth observation sector will contribute a colossal $700 billion (CHF 640 billion) to the global economy. This is a market driven by the desperate need for actionable data.
Beyond the financial windfall, the ecological return on investment is even more critical. These technologies are expected to facilitate the reduction of greenhouse gases by a staggering 2 billion metric tonnes annually by the end of the decade. This dual impact—generating wealth while saving the biosphere—positions the Earth observation industry as a cornerstone of the future economy. As nations grapple with the costs of climate mitigation, the data provided by these satellites offers the most efficient path to slashing emissions where it counts most.
Switzerland is once again proving that its influence extends far beyond its borders. By leading the charge in the Copernicus Carbon Dioxide Monitoring mission (CO2M), Swiss experts are ensuring that the world has a reliable, neutral arbiter for climate data. The work being done at Empa does more than just advance science; it provides the diplomatic and political leverage needed to enforce international agreements.
As the constellation of satellites grows and AI models become smarter, the margin for error—and the room for excuses—shrinks. Switzerland's contribution ensures that when world leaders meet to discuss climate progress, they will be armed with facts, not guesses. In the fight against a warming planet, Swiss innovation is turning the lights on, ensuring that the world can finally see the true scale of the challenge and the precise location of the solutions.
