Environment (Principles, Governance and Biodiversity Targets) (Wales) Bill

A Welsh Government Bill, introduced by Huw Irranca-Davies MS, Deputy First Minister and Cabinet Secretary for Climate Change and Rural Affairs, in June 2025. The Business Committee has remitted the Bill to the Climate Change, Environment, and Infrastructure Committee.

About the Bill

The aim of the environmental principles provisions is to establish a robust framework for environmental governance in Wales. This framework seeks to addresses three core challenges: combating the combined impact of climate and nature emergencies, protecting the environment from harm, and responding to changes in environmental governance structures following the UK's departure from the EU.

The key purposes of the Bill are to:

>>>>

>>>Establish certain environmental principles and an environmental objective. It will require the Welsh Ministers and NRW, when making policy, and certain other public authorities, when carrying out environmental assessment under the Environmental Assessment of Plans and Programmes (Wales) Regulations 2004 (or any corresponding provision replacing those Regulations), to apply the principles, and to integrate environmental protection.

>>>Establish an independent environmental governance body, the Office of Environmental Governance Wales (“the OEGW”) to provide strategic oversight of requirements on public authorities to: comply with environmental law; make effective environmental law; implement / apply environmental law effectively; and to hold those public authorities to account, in a similar way to the Office for Environmental Protection established by the Environment Act 2021.

>>>Amend the Environment (Wales) Act 2016 to establish a biodiversity target setting framework aimed at halting and reversing the decline in biodiversity in Wales, as well as imposing a duty on the Welsh Ministers to promote awareness in Wales of the importance of, and the threats to, biodiversity.
