2021 is a big year for sustainability policy, with several major climate conferences on the horizon. In the run-up to this autumn’s COP26 and UN Food Systems Summit meetings, we’re sitting down with some of the world’s leading sustainability scholars to get their perspective on what these conferences can achieve and how the public can push for better sustainability outcomes. In our first interview, we spoke with Professor Sir Charles Godfray, director of the Oxford Martin School.
