As a sustainability manager, I want to be able to invite my suppliers to collaborate on reducing emissions within the collaboration tab, so that we can work together to improve the sustainability of our supply chain.

To implement this, you could add a new feature to the collaboration tab that allows the sustainability manager to invite their suppliers to join the collaboration. The feature could include an input field for entering the email address of the supplier, as well as a button for sending the invitation.

Once the supplier has accepted the invitation, they will be able to access the collaboration tab and share data and insights on their emissions with the sustainability manager.
