A range of carbon-labelled citrus fruits have been rolled out in Tesco.

Jaffa-branded oranges, clementines and mandarins with packs featuring the Carbon Trust logo and a number showing the environmental footprint in grams hit shelves this week. Final preparations are also being made to add grapefruit to the line-up.

"We are the first company to cover the whole life cycle of the product, from the field all the way to the peel in the bin," said Dov Warmen, business development manager at Jaffa supplier Mtex.
