Addressing waste While our emissions footprint has the most direct connection to our climate change impacts, we also seek to reduce our overall environmental impact, which includes our work to reduce the waste we generate and increase our use of recycled and recyclable products. Waste in our operations We generate waste in our offices, warehouses, distribution centers and pharmacies. In every McKesson location, we aim to reduce the amount of waste we produce. Where we cannot reduce, we try to reuse materials and seek to avoid sending waste to landfill by donating, recycling or composting. For example, when consolidating office space or moving to a new location, furniture and other office items often go to landfill; but since 2018, we have partnered with a vendor that recycles, resells and donates these items instead. To date, we have completed projects in Houston, Texas; Pittsburgh, Penn.; San Francisco, Calif.; Jacksonville, Fla.; Stoughton, Mass., Farmington, Conn., and Charlotte, N.C. Projects in FY21 diverted 213 tons of furniture and other office items from the landfill. Of the items, 15.5% were donated to nonprofits, 35.2% were resold, 47.8% were recycled, and just 1.3% were landfilled. In addition, as part of our LEED certifications, McKesson aims to divert 75% (or more) of demolition and construction waste from landfills. In 2020, we achieved this goal during the construction of the Jacksonville, Fla., office building.

The year-over-year increase in reported hazardous waste is largely due to improved data quality.
