Implementing sustainability across one large company is substantial feat on its own. Yet for AT&T, we are not just working on sustainability at our own company but trying to embed sustainable business practices at hundreds of companies all at the same time. That is part of what it means to work on supply chain sustainability, from setting a goal to reduce our customers’ emissions 10x our own footprint, to setting goals to reduce energy intensity at our operations, to working with our suppliers to ensure they are living up to the standards we have set for ourselves.
