Food & Farming

Producing food takes land, water and fertiliser and causes about a quarter of all emissions. Food that is wasted carries the same footprint.
Who may be affected
Farmers with thin margins, people who cannot afford healthy food, and communities affected by fertiliser pollution in water.
