A study has found that supermarkets, publishing and the waste and water sector have done best among companies in reducing carbon.
When scored against its metrics for carbon reduction, the report from Carbon Clear found that these three sectors scored best, while engineering and machinery, manufacturing and transport and logistics were bottom of the list.
Marks & Spencer came top out of individual FTSE100 companies for its carbon reduction practices and was followed by BT Group and National Grid.
The remainder of the top ten was formed by Aviva, Unilever, Reed Elsevier, TUI Travel, Sainsbury’s, BSkyB and British Land Company.
Companies were measured by Carbon Clear on to what degree carbon reduction could be measured, an assessment of plans to achieve targets and whether the company offset its carbon emissions.
They were also assessed on engagement with customers and supply chain as well as achievement of certification standards.
