Areas of outstanding natural beauty

What are AONBs?

Areas of outstanding natural beauty (AONBs) are areas of countryside in England and Wales outside national parks which are designated in recognition of their significant landscape value. The primary purpose of AONB designation is 'to conserve and enhance the natural beauty of the landscape'.

Two secondary aims complement this purpose:

•
to meet the need for quiet enjoyment of the countryside
•
to have regard for the interests of those who live and work there

On 22 November 2023, all designated AONBs in England and Wales were rebranded as ‘National Landscapes’, although they are still referred to as AONBs in legislation and policy.

See Practice Notes: Areas of outstanding natural beauty (National Landscapes), Biodiversity and nature—protected sites and Non-statutory designated areas.

Responsible authorities

Natural England, Natural Resources Wales, Department of the Environment, Food and Rural Affairs (Defra), and local planning authorities (LPAs) all play a role in designating and enforcing AONBs.

DfT launches consultation on proposals to support transition to ZEVs

The Department for Transport (DfT) has launched a consultation, seeking views on proposals supporting the UK's transition to zero emission vehicles (ZEVs). The consultation is divided into two parts. The first, conducted solely by the UK government, focuses on phasing out the sale of new petrol and diesel cars from 2030. It seeks input on ending the sale of new internal combustion engine cars from 2030, potential requirements for new non-zero emission vans to be sold from 2030 to 2035, considerations for small volume manufacturers, and measures to support ZEV uptake. The second part, conducted in collaboration with devolved administrations, examines the ZEV Mandate, delivered though vehicle emissions trading schemes. It seeks views on existing flexibilities and potential technical updates to the Mandate, which will inform future amendments to the Mandate and CO2 emissions regulation. The consultation closes on 18 February 2024.

NESO submits connections reform proposals to Ofgem

The National Energy System Operator (NESO) has submitted a series of connections reform proposals to Ofgem, including Code Modifications CMP434, CMP435, and CM095, along with three proposed connections reform methodologies. If approved, these reforms will prioritise projects based on readiness and alignment with the government's Clean Power 2030 (CP30) Action Plan 2030, introduce new delivery requirements, and eliminate stalled projects from the queue. Ofgem is expected to make a decision on these proposals in Q1 2025. Subject to approval, these changes, along with associated licence modifications, will facilitate the implementation of a reformed connections process starting in May 2025. An evidence submission window will open in Q2 2025, providing project developers in the current queue a minimum of two weeks to submit a Gate 2 declaration/application. NESO will then review submissions and work with network companies to establish the new connections queue via the ‘Gate 2 to Whole Queue’ exercise. NESO plans to begin issuing Gate 1 offers from Q2 2025 and aims to issue Gate 2 offers as soon as possible in 2025.
