As the use of artificial intelligence grows, there’s a risk that it could boost emissions as it drives up demand for energy at data centers. But AI also has the potential to help find new ways to shrink humanity’s giant carbon footprint. At Google, research teams are working on more than 20 AI tools to fight climate change and deal with impacts like flooding and wildfires.

“We all know that we need climate breakthroughs, and we need them quickly. We also know that we’re seeing an extraordinarily fast pace of innovation in the field of AI,” says Juliet Rothenberg, the product lead for Google’s climate AI work. “What’s so exciting about our work in climate AI is that we’re bringing the pace of AI innovation to tackle the climate challenge, and we’re seeing very meaningful results very quickly.” Google recently partnered with Boston Consulting Group on an analysis that suggested AI could help eliminate as much as 10% of emissions by 2030.

While AI can be used in a multitude of ways, the company looks for areas that could have a particularly large climate impact and where Google “has a special sauce to bring to the space,” Rothenberg says.

For its work on climate AI, Google is Fast Company’s World Changing Company of the Year. Here are a few of the company’s tools that are already in use.
