Food Giants Try Carbon Labels to Solve Their Climate Problem

How green are those breakfast sausages on your plate? What about the Lay’s potato chips you’ll snack on later? And that Perrier to wash them down?

Nestle SA, Pepsico Inc. and local brands are among the 27 companies backing a project that calculates a product’s environmental impact from farm to store and then grades it with a color-coded label. It’s the first time a partnership this big is working to find a one-size-fits-all way to assess the supply chain.

The global economy must reduce CO2 emissions to keep the planet from frying, and the food industry is responsible for as much as 35% of those. With investors scrutinizing environmental bona fides and governments publishing net-zero mandates before the COP26 climate summit, producers are being pushed to reduce their carbon food-prints.

“We’re looking to transform the food industry,” said Cliona Howie, chief executive officer of Foundation Earth, a London-based nonprofit organization leading the project.

The World Bank estimates it will cost $350 billion a year over the next 10 years to green up the supply chain and boost productivity.

Emissions start with the methane belched by cows and pigs, the gases released by rice rotting in paddies, or the chemicals spread in fertilizer. Animal-based products generate 57% of the industry’s greenhouse-gas emissions, according to a study published in the journal Nature.
