The certification process acts to identify inefficiencies in resource use and provides a framework for improving management processes, reducing waste and costs.

Achieving the Carbon Trust Standard provides independent and internationally recognised verification of your achievements in reducing resource use and waste and offers tangible proof to customers, employees, shareholders and suppliers that you are committed to sustainability.

There’s a clear business case for managing and reducing our own impact on the environment. It saves money, helps us become more efficient and better prepares M&S for the future. Working with the Carbon Trust gives us the knowledge and confidence to push ourselves further and supports us in achieving our ambitious Plan A goals.

Carbon Trust Product Footprint Certification

A product footprint provides an independent and accurate assessment of the total sum of greenhouse gas emissions (CO2e) or water used throughout a product’s lifecycle, including manufacture, distribution, use and disposal.

Footprinting provides real benefits, including the identification of carbon hotspots and water intensities in the product lifecycle, which typically lead to improvements in resource efficiency and subsequent costs savings.

The Footprint Label can be used to publicly brand footprinted products to communicate their sustainability credentials, build your reputation and drive sales with today’s ever more environmentally aware consumers and business buyers.

Products as diverse as bread, milk, crisps, wine, smart-phones, hand dryers, paper & envelopes, packaging, bins and even corrosion inhibitors have all been footprinted by the Carbon Trust and awarded the Footprint Label.
