Jaega Wise explores how environmental-impact labels on food and drink products could help lower the carbon footprint of the food industry. Although there’s been an increase in the number of companies using different kinds of carbon and eco labels, they still appear on a small minority of products. There are growing calls for there to be a unified system for calculating the environmental impact of food production – one that not only measures carbon emissions, but also other impacts like water use and biodiversity loss, all using the same internationally agreed method so shoppers can compare products fairly and accurately.

Presented by Jaega Wise and produced by Sophie Anton for BBC Audio in Bristol.
