But it’s more than just transitioning to renewable energies: it’s designing out waste and pollution before production and manufacturing even begin.

For example, in 2021, we entered into a VPPA in Europe that will produce 37.5 MW of solar energy with benefits beginning in 2023. · We have appointed a designated supply chain sustainability professional to lead proactive and targeted sustainability focused engagement efforts with suppliers to understand and mitigate market and value chain risk exposure.
