Doing a complete audit of your supply chain involves not only environmental, but social and ethical considerations.
In addition to checking your suppliers are operating in an environmentally responsible manner, with minimal packaging, and products are manufactured using ethically sourced materials and without harm caused to people, animals, or the planet, a thorough supply chain audit also covers slave labour, fraud, bribery and corruption.
