Tesco is hoping to claw back some media attention from Marks & Spencer, with an announcement of further plans to combat climate change due later this week.
Sir Terry Leahy, Tesco's chief executive, will address environmentalists at an event hosted by the sustainable development charity Forum for the Future on Thursday (January 18).
He is expected to unveil ways in which consumers can help cut their own carbon footprints by buying homegrown produce.
Tesco has already pledged to invest £100 million in sustainable environment technology but this falls well short of the ambitious£200m plan unveiled yesterday by M&S.
Meanwhile, not all NGOs are wholly pleased with the retailers' green schemes.
Friends of the Earth food campaigner Sandra Bell said the multiples are still failing to tackle the "fundamental issue about the way they do business and the way they treat their suppliers", leaving farmers with "far less money to invest in environmental improvements".
