Section 6 under Part 1 of the Environment (Wales) Act 2016 introduced an enhanced duty (the S6 duty) for public authorities in the exercise of functions in relation to Wales.

The S6 duty requires that public authorities must seek to maintain and enhance biodiversity so far as consistent with the proper exercise of their functions and in so doing promote the resilience of ecosystems.


To follow the S6 duty public authorities should embed the consideration of biodiversity and ecosystems into their early thinking and business planning, including any policies, plans, programmes and projects, as well as their day to day activities. 

We have produced guidance to assist and support public authorities to follow the S6 duty in the exercise of functions in relation to Wales.  

Public authorities must have regard to this guidance and any other guidance given to it by the Welsh Ministers.
