Our Planet
Improving our Planet
As an impact-driven organization, we are guided by our purpose of Advancing Health Outcomes for All® and are committed to creating solutions for a healthier environment.
Our Green Building Standards
The introduction of the McKesson Green Building Standards (GBS) marks a significant milestone in our sustainability journey. GBS is a customized framework that delivers measurable environmental benefits across McKesson’s diverse global portfolio—including supporting our commitment to achieving our SBTi targets for GHG reduction.
In FY25, nine sites have achieved GBS certification, and McKesson continues to expand GBS assessments to ensure facilities meet the rigorous standards the GBS provides. By combining energy efficiency, flexibility and occupant wellness, the GBS empowers teams with a clear, actionable path to positive environmental impact and enhanced wellbeing of employees and patients alike.
Our Progress Toward Supplier Engagement
We continue to make progress in reducing greenhouse gas (GHG) emissions across our value chain. In FY25, we achieved our goal of having 70% of our suppliers, by spending on purchased goods and services, set SBTi-approved GHG reduction targets. Our climate targets align with limiting global warming to 1.5°C, joining more than 10,000 companies worldwide committed to reducing GHG emissions.
Reducing Our Carbon Footprint Across Our Business Operations
From increasing our use of renewable energy to deploying more sustainable packaging and reducing waste, we are moving forward with green initiatives.
McKesson’s Virtual Power Purchase Agreements (VPPAs) can be useful tool to help procure energy from renewable sources in support of our GHG emissions reduction strategy.
In FY25, McKesson invested in a new VPPA and became a virtual customer of Recurrent Energy’s new 100-MWac/134-MWdc Liberty Solar plant in Liberty County, approximately 50 miles northeast of Houston. The Liberty Solar plant reached commercial operation in October 2024 and can generate enough electricity to power around 15,000 homes annually. Through the Liberty Solar plant, McKesson is helping to reduce annual carbon emissions by an impressive 182,000 metric tons—equivalent to taking 39,000 cares off the road.
Greenhouse Gas Emissions Reduction
We know that we have a pivotal role to play in reducing greenhouse gas (GHG) emissions across our value chain. That’s why we have committed to working with our suppliers in connection with our Science-Based Target initiative (SBTi) targets.
SBTi, a collaboration between CDP (formerly the Carbon Disclosure Project), the United Nations Global Compact, World Resources Institute and the World Wide Fund for Nature, drives climate action in the private sector by encouraging companies to set targets to limit global warming to 1.5°C. McKesson has joined companies across the globe committed to setting and achieving targets to reduce GHG emissions toward this goal.
We also engage with the National Academy of Medicine, Collaborative for Healthcare Action to Reduce MedTech Emissions, Sustainable Purchasing Leadership Council and The World Business Council for Sustainable Development WBCSD on reducing GHG emissions.
We are taking steps designed to reduce both our direct GHG emissions and those produced in our upstream and downstream value chain.
