Tesco, Marks & Spencer and Sky front green campaign
B&Q has come together with seven UK businesses as the Climate Group to help reduce the UK's carbon dioxide emissions.
Companies in the group are B&Q, Barclaycard, British Gas, Marks & Spencer, O2, Royal Sun Alliance, Sky and Tesco.
Each member is offering measures to encourage households to reduce their emissions by one tonne over the course of a campaign, 'We're in this together'.
As a member of the group, B&Q has pledged to help consumers reduce their carbon dioxide footprint with a range of easy-to-install insulation products.
Ian Cheshire, CEO of B&Q, said: "We're delighted to be part of the 'We're in this Together' campaign, and enable our customers to make a real difference to the environment, whilst saving themselves up to £220 a year."
