Reduce food waste
Food waste is a huge problem. In Guildford alone, 50,000 slices of bread are wasted every day (Zero Carbon Guildford), which is enough to provide three sandwiches per day for the number of people struggling with the cost of living.
Food waste is also a major contributor to climate change, as it decomposes, it creates methane, a greenhouse gas that is about 30 times more effective at trapping heat than carbon dioxide (CO₂). If food waste were a country, it would be the 3rd largest emissions producer.
About one-third of food grown never even makes it off the farm, in part due to the aesthetics rules of supermarkets.
