The vehicle auction giant was awarded the certification following a two-year assessment programme that involved employees across the organisation taking part in training days and internal reviews.

“We have achieved a significant reduction in our environmental impact across all of our locations,” said Pete Lacey, Manheim’s group risk manager.

“The focus has been on recycling at every opportunity, carefully disposing of hazardous material and looking at ways to reduce the total fuel used across the business.”

In addition, PJM Valeting, which operates vehicle preparation facilities across Manheim’s UK sites, has been awarded the five star mark by the Green Achiever Scheme, which endorses businesses that work towards environmental best practice. PJM has limited the temperature of its washes to save fuel, reducing energy consumption by setting machinery on timers and recycling a wide range of waste streams.

In 2011 Manheim said it removed over one million square feet of sign writing from commercial vehicles as well as over 25,000m3 of rubbish.
