Caroline PETIGNY, AFYREN's Chief Sustainability Officer, stated: "These new ratings place us in the exclusive circle of the most committed companies. They provide strong recognition of the relevance of our circular, low carbon greentech model and are a testament to our commitment to continuous improvement.
