Your Sustainability Portal account isn't just for Project Gigaton. It's your one-stop-shop to manage participation and reporting for Walmart's major sustainability initiatives, including Project Gigaton, THESIS (formerly The Sustainability Index), Packaging and Forests.

Watch this video if you need help creating a Sustainability Portal account. To create a Sustainability Portal account, you’ll first need a Retail Link account which you can create or reset a password for here. If you're not sure what Retail Link is, or need to find out your vendor number, ask your company's sales team. If you previously had a Project Gigaton account, this has already been transitioned into a Sustainability Portal account for you – so go ahead and sign in!
