KEY POINTS:
British supermarket giant Tesco's has pledged to label every product with its "carbon footprint" - the amount of carbon dioxide generated during its production and distribution - to help customers choose environmentally-friendly goods.
The moves, which are designed to appeal to the growing number of "green shoppers" as well as help cut Tesco's overheads, follows a pledge from Marks & Spencer to be carbon neutral within five years, according to a report in the Telegraph newspaper today.
Other UK supermarkets are expected to unveil their green agendas over the next few months.
Sir Terry Leahy, Tesco's chief executive officer, announced the plans during a speech on climate change in which he promised to lead a "revolution in sustainability".
The Telegraph reported Sir Terry as saying Tesco would bring down the cost of being green and provide better information to help shoppers make green choices.
