Ruminating on sustainable food systems in a net-zero world

For as long as sustainable food systems have been on the global agenda, the meaning of ‘sustainable’ has been hotly debated.

A contextual, transparent and nuanced debate can avoid policies informed by vested interests and straw-man arguments, which can backfire and hurt many of the very interests that the sector and policies aim to protect.
