Waste Recycling Group has been ranked in the top 10% of a carbon-fighting league table.
The firm was placed 140th out of more than 2,000 organisations in the Carbon Reduction Commitment league table.
The CRC Energy Efficiency Scheme, introduced by the government three years ago, requires qualifying companies to record efforts to tackle carbon emissions.
WRG environment manager Paul Stokes said: “This was a very significant achievement for WRG and it acknowledges the hard work that our carbon reduction team has undertaken since the Energy Efficiency Scheme was introduced in 2008.
“From the start, our focus has been on reducing our energy use and developing initiatives within the business to ensure that we continue to drive down costs.
“The benefit, of course, is two-fold – improved efficiency and profitability for the business, and the reduction in carbon emissions which helps to offset damaging climate change.”
