Tesco will demand that its suppliers look at their carbon footprints and work towards cutting their impact on the environment, BWS head Dan Jago has said.
Jago told the London International Wine Fair
: " This will become a criteria for doing business with Tesco .
"We have to make it easier for customers to make green choices - we must empower everyone, not just the affluent or enlightened," he said.
Jago detailed Tesco's work to cut its environmental impact, such as giving customers extra Clubcard points if they use fewer carrier bags, promoting energy-efficient light bulbs at 1p and switching logistics from road to rail and shipping.
On the BWS side, Tesco has boosted bulk shipping and worked with the Waste & Resources Action Programme to lightweight its bottles. But Jago noted that some suppliers are "set in their ways around branded packaging".
He said: "We cannot achieve our ambitions unless the whole industry believes in the importance of this issue . It is clear that we have passed the point of choice, and Tesco is determined that it should be a leader in creating a low carbon economy."
