Last week’s article does not quite capture our position.

We have set ourselves demanding targets: to reduce carbon emissions in the products we sell by 30% by 2020, and to find ways to help customers reduce their carbon footprints by 50% by 2020. We believe carbon labelling plays a really important role. What is correct is that the scheme we developed with the Carbon Trust, although it has many merits, has not yet been widely adopted by others.

So we are not withdrawing from carbon labelling, an important innovation. We plan to continue carbon footprinting. This process helps us understand where emissions arise and identify opportunities to reduce carbon. It also helps our customers, giving them information to help them choose the greener option. We’re proud to have footprinted over 1,100 products, more than any other UK company by sales volume. We have labelled 500 of these since 2008 and are committed to continuing our footprinting.

We want to find faster and cheaper ways to footprint and label. We are learning from the labelling we are doing and working with the Carbon Trust and other partners so we can do even more to help customers live greener lives.
