This White Paper sets out the Government's detailed proposals for the reform of the planning system, in light of the recommendations made by the Barker Review of Land Use Planning (2006, ISBN 9780118404853) and the Eddington Transport Study (2006, ISBN 9780118404877). These proposals are designed to ensure the planning system can meet a number of challenges including: climate change, supporting sustainable economic development, increasing the supply of housing, protecting and enhancing the environment and natural resources, improving local and national infrastructure and maintaining security of energy supply. For the first time, the reforms cover all development consent regimes, including those for major energy, water, transport and waste development, as well as the town and country planning system. The proposals are based on five core principles: i) responsiveness and integration of economic, social and environmental objectives to deliver sustainable development; ii) a planning system which is streamlined efficient and predictable; iii) full and fair opportunities for public consultation and community engagement; iv) transparency and accountability; and v) planning decisions taken at the right level of government, whether national, regional or local.
