GSA’s industry partners and peers — including (among others) dozens of major retailers, automakers, electronics manufacturers, financial companies, and hospitality companies — consistently share with us that working with suppliers to reduce their energy and environmental footprints can increase efficiencies and reduce business risks for all parties, generating cost savings and other forms of financial value. GSA is working to adopt these industry best practices for supply chain management as an important best-value component of solutions that vendors provide to the federal government.
In 2015, GSA supplemented these efforts by joining CDP Supply Chain, a third-party supply chain disclosure system. Contractor participation in GSA’s CDP Supply Chain program is by invitation only, and is voluntary for invited contractors, unless separately required by contract.
GSA develops contract requirements for energy and environmental management based on anticipated cost savings and impact opportunities, unique to each procurement and market sector. GSA believes that a market sector approach is best, since it aligns with other GSA strategic sourcing practices and recognizes that opportunities to reduce costs via energy and environmental management differ between market sectors, depending on the relevant impacts and practices of each sector. GSA tracks, via an annual survey and analysis process, actions that major federal contractors are taking to reduce their emissions and the impacts of these actions. GSA also includes and monitors contract requirements for contractors to track and reduce emissions in several dozen contracts within the FAS Alliant 2 GWAC program.
To assist vendors in identifying relevant sustainable management practices, the following tables provide links to resources and information.
