At this year's New York Climate Week, artificial intelligence has become the unavoidable topic. UN Secretary-General António Guterres framed the issue as a double-edged sword, noting that AI could either help solve climate challenges or make them worse. The backdrop is a recent UN Environment Program report indicating that the world has nearly missed the 1.5°C warming target, making the debate over AI's role more urgent.
The technology's energy appetite is a central concern. Data centers needed for AI are driving a surge in natural-gas power plants, which could operate for decades and lock in emissions. At the same time, climate-tech investment has jumped 55% in the first half of 2026, with data-center-related products and services capturing a large share. However, sectors like carbon management and low-carbon fuels have seen venture capital plummet, raising questions about whether AI's benefits are reaching the most critical climate solutions.
Some experts remain optimistic, pointing to AI's potential to accelerate research in areas like catalyst discovery. But the overall mood among climate leaders is skeptical. UN climate chief Simon Stiell warned that 'AI leaders are now on thin ice' regarding public support, and urged tech titans to demonstrate that AI's benefits outweigh its skyrocketing costs for the many, not just the few.
