Robert Downey Jr has signed a deal to publish a new book about climate-solving food choices.

He will release Cool Food: Erasing Your Carbon Footprint One Bite at a Time with co-author Thomas Kostigen, reports Deadline.

“Our best global food future requires no hand-wringing, fad diets, or radical shame—just a perspective shift to discovering the many solutions in plain sight,” Downey, Jr. said.

Kostigen added: “As the great Yogi Berra once said, ‘The future ain’t what it used to be.’ Increasingly, we are presented with forecasts of a worsening climate. Cool Food shows how we can change that outlook for the better by making a few different choices at the grocery store, trying something new on the restaurant menu, and by keeping an eye out for foods that store more carbon in the ground rather than polluting the air.”

No details of when the book will be published have been announced yet.
