THE UK’s “greenest grocer” has launched an appeal to companies across North Wales to join the carbon zero crusade to help save the planet. The call to arms from Richard Walker, the managing director of pioneering eco-aware supermarket Iceland which has stores across the region, came ahead of Net Zero 2021, a major online business conference. Themes at the conference include Energy and Transport, Manufacturing, Tourism and Hospitality, Food and Retail and Buildings and Construction and the event runs from 9:30am to 3.45pm on Thursday, May 20. Iceland was the first supermarket to sign up to the worldwide Carbon Pledge to become carbon neutral by 2040, ten years ahead of the UK Government’s 2050 target.
