Many of the problems of the disposal of munitions at the end of their lives are a consequence of the decisions taken during the acquisition phase. The smart acquisition process; introduced by the UK Ministry of Defence in the past few years; seeks to address some of the disposability and environmental issues at the key decision points early in the acquisition process. The business case for any munition acquisition needs to consider the whole life costs; which include those for disposal as well as examining the implication of ownership on the environment. This paper describes some of the work underway in the UK to develop standards and methodologies to enable environmental and disposability requirements to be specified at the acquisition stage. In particular; it describes the application of Environmental and Safety Compliance Levels (ESCL’s) in munitions acquisition.
