Is that product or service sustainability claim true?

Is that product or service sustainability claim true?



Sustainability is no longer a USP, but an integral part of any goods or service offered by good companies.  That is a good thing, a very good thing, in fact. It means the days when consumers do not care whether the product they buy was tested on animals or not. Whether children working in ghastly conditions, round the clock, thousands of miles are stitching buttons onto that fashionable shirt, you paid next to nothing is gone. 

An increasing number of consumers want to know how sustainable the product is, or how environmentally friendly the service is. Many large organisations, including government agencies, want sustainability certifications or statements from their suppliers before a deal can be done or a contract approved. This has led to manufacturers and suppliers making environmental claims about their products and services. 

How do you know that the environmental claim made by a product or service is true? How do you ensure a product is not jumping on the bandwagon by greenwashing its products or services?  

One of the best ways to ascertain a product’s or service’s environmental claims is through third-party certification. The thing is that there are an awful lot of green certification organisations out there. How do you know which is which?  This article looks at  some of the most widely known and respected sustainability certification organisations in the UK.
