We’re honored to be among the Sustainability Award Winners for Operational Excellence by Puget Sound Business Journal!
Three years ago, MacDonald-Miller signed both The Climate Pledge and MEP 2040, formalizing a long-term commitment to reduce carbon impact across the full life cycle of the mechanical, electrical, and plumbing systems we design, build, and support.
Since then, we’ve focused on turning that commitment into real, measurable action. We’re using our own footprint across 13 buildings in the Pacific Northwest as a proving ground for solutions like smart building services and sub-metering, helping us learn faster and apply what works in the field.
From transitioning our 800-vehicle fleet toward zero-emission options, to exploring reusable air filter alternatives, to mapping the carbon impact of the products we specify across the supply chain, we’re pushing for practical progress that reduces emissions today while building momentum for what’s next.
