Our Planet


Improving Our Planet

At McKesson, we know that the health of our planet directly influences the health of patients and our communities. That understanding guides our commitment to environmental stewardship as a core pillar of our impact strategy. By embedding sustainability into how we operate and evolve, we aim to reduce environmental risk, strengthen resilience across healthcare and create healthier futures for the patients we serve.

Our Green Building Standards

McKesson’s Green Building Standards (GBS) continue to drive consistency in how we design, build and operate our real estate portfolio.. GBS is a customized framework that delivers measurable environmental benefits across McKesson’s diverse global portfolio, including supporting our commitment to achieving our Science Based Targets initiative (SBTi) targets for greenhouse gas reduction. Our GBS continues to drive consistency in how we design, build and operate our real estate portfolio. Since inception, we've assessed 52 buildings and achieved 17 GBS certifications, including three Platinum, two Gold, 11 Silver and one Compliant.

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 11,000 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 suitability initiatives.

In FY26, approximately 32% of the electricity used for McKesson buildings was from renewable energy, marking continued progress toward our enterprise-wide goals. This progress is driven by a diversified approach to renewable energy procurement and investment. We combine investments in wind and solar projects with green energy purchases, including Virtual Power Purchase Agreements (VPPAs) that add new clean energy to the grid as a part of our broader approach towards meeting our emission reduction goals. Through these investments, we’re expanding renewable energy while reducing annual carbon emissions by about 48,000 metric tons — equivalent to the emissions from powering nearly 6,500 homes — a reflection of our commitment to doing what’s right for our planet.

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 NAM, 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.
