Below is a link to a paper savings calculator that Environmental Defense, a leading environmental organization, has created.
This is a great tool to use on projects to determine the environmental benefits of a specific paper with post-consumer content, versus its virgin fiber alternative. I prefer using this tool over other tools because it is a third-party resource, not affiliated with the paper/print/marketing industries. It’s transparent and backed by an organization that is not-for-profit focused on “tackling the most serious environmental problems.”
