Sustainable Procurement Key to Lowering Carbon Footprint Credit: iStock/Tryaging As more companies focus on reducing their carbon footprint, there’s one element that is key but often overlooked — reducing emissions from their supply chains. Anastasia O’Rourke ’09 PhD who is managing director of the Yale School of the Environment’s Carbon Containment Lab, focuses on advancing sustainable and green purchasing, and helping organizations look for opportunities in their own supply chains to make a positive impact on reducing carbon emissions. She is a founding board member of the nonprofit Sustainable Purchasing Leadership Council (SPLC) and will be delivering a workshop on buying credible carbon offsets during its Deep Dive series this week, which is open for public participation.
