Ecovadis
Our partner in sustainability
Environmental, social, and ethical performance—or sustainability—is an essential factor for Calix, and the supply chain is one of the biggest levers for impact. Partnering with EcoVadis, the world’s most trusted provider of sustainability ratings, we create transparency in our supplier network and to build a more sustainable future for all.
Sustainability has become a key part of our supplier onboarding process. Most Calix suppliers not only participate in assessing themselves with EcoVadis, but have also completed almost 100 classes in the EcoVadis academy.
