2. “Meeting the Needs” 2002 “Sustainable development is about holistic thinking and promoting integration rather than about making trade-offs. It will not be achieved simply by weighing competing demands in the balance. It is not a matter of economic development versus environment but of development based on proper management of environmental resources and consideration of full life cycle impacts and costs. We are committed to development but it must be development which both protects our environment and enhances our quality of life.”

3. National Planning Framework for Scotland 2004 “The Executive is committed to integrating the principles of sustainable development into all of its policies.” “Action is required to address the threat posed by climate change and on the sourcing and use of materials and waste recycling. There is a need to use resources more efficiently, reduce energy consumption and CO2 emissions, and develop renewable sources of energy. We need to move towards more environmentally sustainable and socially inclusive modes and patterns of transport.”

4. UK sustainable development strategy - March 2005 Priorities: Sustainable consumption and production Climate Change and Energy Protection of Natural Resources & Environment enhancement Creating sustainable communities And three key themes: Involving people Government leading by example Getting serious about delivery

5. One future – different paths The UK’s shared framework for sustainable development 2005 “The goal of sustainable development is to enable all people throughout the world to satisfy their basic needs and enjoy a better quality of life without compromising the quality of life of future generations.” “that goal will be pursued in an integrated way through a sustainable, innovative and productive economy that delivers high levels of employment, and a just society that promotes social inclusion, sustainable communities and personal well-being. This will be done in ways that protect and enhance the physical and natural environment, and use resources and energy as efficiently as possible.”

26. Flexibility and future proofing: Average residency is 7 years (home.co.uk). Length of residency increases with age (require less mobility) People often have to move to increase the size of their family – but frequently move locally (JRF) Less well off tends to mean less mobile Importance of garden increases and then decreases with age 91% of single pensioners and 53% of pensioner couples do not own a car and are dependent on public transport (DFT) Turn over of housing stock Embedded energy and water in materials Climate change
