Tesco has installed wind turbines at three of its distribution centres in England and Wales.
The retailer, which wants to be carbon neutral by 2050, has put up two 90-metre turbines at Crick in the Midlands and Magor and Newport in Wales.
Tesco renewables manager Jake Ronay said: “The wind turbines will make a major contribution to our electricity needs at the distribution centres, in a clean and quiet manner.
“Each year the turbines will save approximately 3,200 tonnes of CO2 being emitted into the atmosphere.”
Earlier this year Tesco chief executive Sir Terry Leahy called on governments around the world to work with private companies to ensure that innovation in low-carbon growth is not hindered by red tape.
Announcing the opening of two zero-carbon stores in Thailand and the Czech Republic, he said governments needed to create the regulatory environment that will allow private companies to lead the way in bringing about economic growth that is sustainable in every sense, working to make green choices cheaper, simpler and more attractive to consumers.
“Regulation has its place in setting the right framework for action on climate change, for example through an effective carbon price. But I believe in the power of the market and in people’s creativity to tackle major challenges. Governments can help create the right framework, but they cannot match the energy and innovation of the market.”
