Justin King has ruled out the possibility of introducing carbon labelling to Sainsbury’s products in the near future.

Speaking exclusively to The Grocer, King said Sainsbury’s was sceptical as to the benefit of any such logo.

“We don’t see imminently that we’ll be in a place where we’d put anything on pack,” he said.

King claimed that carbon labelling could, to some extent, be misleading for the consumer as existing models only mapped the carbon footprint up to the shelf. Much of the carbon footprint of a potato, for example, was created in preparing it after purchase.

“We are yet to see a model proposed that would provide consumers with information that would allow them to make a decision.”

He said Sainsbury’s approach would be to communicate the message more generally rather than through on-pack labelling.
