Some Evergreen projects share several variables among them. At present, Evergreen offers two REST routes to manage variables which allows copying variables to an existing project and rotating variables .
However, there's currently no UI-driven mechanism to share variables across projects. Lack of cross-project variables management creates administrative burden for project owners as they need to copy/paste variables across projects and update variables across several projects manually. Evergreen could potentially provide an interface to allow cross-project variable administration easier.
