Managing carbon emissions in your supply chain is a constant challenge. You may have control over your own facilities and operations, but it's hard to influence the sustainability practices of third-party carriers and 3PLs. Your request for proposal (RFP) process provides a powerful (and frequently untapped) lever. By including language about registering with EPA's SmartWay Transport Partnership, you can use your RFPs to encourage truck, rail, logis-tics, and multimodal carriers to participate in SmartWay and help you quantify your supply chain’s carbon footprint at the same time.
