Supply Chain Sustainability School

Briggs Amasco Ltd is a Gold member of the Supply Chain Sustainability School.

We joined in 2012 when the School was launched by a small group of main contractors, as an approach to addressing sustainability within the construction industry supply chain.

It now has more than 50 partners and 10,000 members, and provides free practical support in the form of e-leaning modules, tailored self assessment and action plans, sustainability training and networking opportunities.

The School continues to be delivered by an independent third party, Action Sustainability, maintaining confidentiality of the information we provide.

Janice Tyler, BriggsAmasco’s Environment & Supply Chain Manager, leads our involvement with the School and manages the assessments and action plans. Janice has presented at a number of supplier days, including the launch of the new Welsh school in Cardiff during March 2017, where we received very positive feedback from the partners.

As a Gold member we have attended “invitation only” workshops where partners and selected members have discussed the vision of the School and also its values.

Training workshops we have attended include the Modern Slavery Act, Fairness, Inclusion and Respect, Sustainable Procurement, The Apprenticeship Levy, Waste Management. The learning from these, and from on-line resources, is then used to provide in-house training and information for our staff, operatives and sub-contractors.
