In 1998, Bentley became the first automotive company to achieve the ISO 14001 environmental management standard. This is an internationally recognised tool that helps organisations to manage and reduce their environmental impacts. Building on this, in 2018 Bentley was re-accredited to the ISO 5001 standard, which helps organisations manage energy use through the implementation of an energy management system. Bentley also has several certifications with the Carbon Trust. This independent organisation helps companies such as Bentley contribute to, and benefit from, a more sustainable future through carbon reduction and energy efficiency strategies. Bentley has achieved the Carbon Trust Standard in: Energy, Waste, Carbon and Carbon Neutrality.
