What we hear from health systems

Commitments are easy to make. Knowing what to do first is harder.

Pledges need a plan

Many health systems have made decarbonization commitments, but lack a clear, prioritized roadmap with measurable KPIs.

Supply chain and clinical care dominate

Much of healthcare's footprint sits in purchased goods and clinical practice — areas that energy audits alone don't address.

Leadership wants the business case

Sustainability initiatives compete for budget. Leaders need to see operational and financial returns alongside environmental ones.
