We measure and report on our overall carbon emissions, energy, water use, and waste disposed. We include data gathered from 16 manufacturing, R&D, and distribution facilities located in North America, South America, Asia, and Europe, representing (based on square footage) approximately 88% of our operations. For the remaining 12% of square footage, primarily administrative offices, we estimate energy usage to calculate carbon emissions. We measure progress toward our targets by quantifying results independent of growth or contraction of our business. We do not include facility or building closures or recently acquired facilities in our target progress. Our 2021 environmental data have undergone a reasonable assurance audit.



We're data driven and strategic in our approaches to reduce carbon emissions.


Water is a vital resource for our business that we are working to conserve.


We are studying ways to eliminate waste at its source.


We're making progress towards achieving our 2027 conservation targets.
