German supermarket chain Tengelmann opened its first "green" supermarket yesterday (2 December), as part of the company's bid to cut CO2 emissions by 20%.

The new supermarket produces 50% fewer carbon emissions and uses less energy than a regular outlet by utilising solar panels, geothermal power, daylight-controlled lighting systems and LED lighting, the company said.

A spokesperson for Tengelmann told just-food that the move was in-line with the group's wider strategy to tackle climate change, which encompasses a number of other initiatives.

"This is an important step," the spokesperson said.

"We also aim to reduce our impact on the environment by taking such actions as using green electricity and forming annual emissions balance sheets."
