Google has one of the most ambitious climate targets in the tech world, but what happens if it falls short of its goals? How does the company balance innovation with environmental responsibility? And can AI really help reduce emissions?

This week on Cleaning Up, Bryony Worthington sits down with Kate Brandt, Google's Chief Sustainability Officer, to unpack these critical questions. Brandt offers an insider's view of how one of the world's most influential companies is tackling the climate crisis, from tackling its own emissions to the impact of misinformation on its platform. Brandt has a fascinating background, having spent time in both the Pentagon, and advising President Obama on energy security and sustainability issues. In her current role, she oversees the team working to reduce Google's environmental impact.

Google has set itself an ambitious company-wide climate goal of halving their 2019 emissions by 2030 but their latest sustainability report showed that they were off track, as the company has grown and increased their investment in energy-hungry artificial intelligence. As providers of curated information at a global scale, Google has a unique intersection with the climate problem. Primarily, their impact comes from the electricity they buy, but they're also able to guide customers' decisions through the provision of information and through their parent company Alphabet.

They've made some pretty bold investments in innovative, disruptive companies, so measuring their impact is arguably more than the sum of their Scope 1, 2 and 3 emissions. Nevertheless, missing a clear target can't be very comfortable. Brandt discusses the company’s ambitious yet challenging emissions reduction targets, the transformative potential of AI in environmental solutions, and the innovative clean technologies that might just help us reimagine our energy future.

From predicting floods and reducing aircraft emissions, to molten salt batteries and grid optimization technologies, this conversation reveals how Google thinks about innovation and the climate.
