Industry support for the GBTA Sustainable Procurement Standards

AMC Networks International

Andrew Cassidy, Corporate Travel Manager

“As corporate travel leaders increasingly work towards reducing their organisations’ environmental impact, a major challenge for both buyers and suppliers is the lack of any agreed industry-wide framework for sustainability. Through harmonization of multiple sets of standards, GBTA’s Sustainable Procurement Standards is an impactful progression towards all stakeholders being aligned across multiple verticals. In addition to the flexible approach enabling buyers to focus on what’s most important to their organisations, and the ability to finally all be ‘on the same page’, these resources provide a way for Suppliers to effectively communicate their credentials in an efficient manner. The information can be embedded into procurement processes and/or used for reporting purposes.”
