Welcome to Sheffield Environment Weeks

Since 1984 Sheffield Environment Weeks has been promoting the groups we work with and their environmental events. Whether you're a group who is already involved with us, a new group looking for ways to promote yourself, or someone looking for something to do we hope you'll find this a useful resource.

This year's Sheffield Environment Weeks dates are from Saturday 2nd May 2026 to Sunday 14th June 2026. We're going one week later in 2026 to incorporate both World Environment Day and the Great Big Green Week, which runs 6th - 14th of June.

You can add a group or an event by registering to the site. We will check anything you upload.
