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.

So what would it take for environmental labelling to become widespread? Jaega Wise talks to non-profit organisation Foundation Earth about their plans to establish an eco-impact label that could be used across Europe. We look at how a more harmonised approach could encourage more companies to get on board, increase public trust, and trigger change across food supply chains as companies look for more eco-friendly ways of producing, manufacturing, transporting and packaging food.
