Measuring and Reducing Supply Chain Emissions (Scope 3, categories 1 and 2)

In Stage 4, “Measuring and Reducing Supply Chain Emissions (Scope 3, categories 1 and 2),” health care organizations focus on the greatest sources of their overall greenhouse gas emissions: the goods and services they buy, including capital goods (supply chain). In the supply chain, greenhouse gas emissions accumulate much like a food chain. The extraction and production of raw materials generate emissions, which are then carried into the manufacturing of supplies and equipment, introducing additional embedded greenhouse gases. This process continues through distribution, use, and final disposition, with each phase adding its own emissions. Health systems that purchase goods may not have control over the entire chain, but they can choose suppliers who actively work to reduce greenhouse gas emissions throughout the entire product life cycle.

This stage involves quantifying supply chain emissions and initiating measurement and reporting. Engaging supply chain partners, advocating for sustainable practices, and adopting relevant metrics and standards are essential components of this stage. Through these actions, health care organizations can significantly reduce their greenhouse gas emissions and contribute to a more sustainable, equitable, and resilient environment.
