The government has made a commitment to ensure that sustainable development is placed at the heart of decision-making. The UK's strategy has primarily involved the development of voluntary measures to achieve sustainable development in policy-making. These measures are monitored by a Sustainable Development Commission and, most importantly, a parliamentary Environmental Audit Committee. However, a number of public bodies also have a statutory duty in respect of sustainable development. These duties do not create enforceable legal obligations, but may have significant value as a clear statement of policy on the achievement of sustainable development – providing political leadership at the highest level. It is essential to this aim that the government provides a clear message regarding the objective of sustainable development. However, close investigation of these duties reveals not only a partial legal framework, but a number of inconsistencies in the government's approach to the achievement of sustainable development.
