Executive Summary
Executive Summary
The Met Office is a unique global institution, delivering integrated weather and climate services. This analysis estimates it will deliver a net economic value 1 of £29.5bn 2 to the UK over the next ten years. There are additional benefits which have been identified, but for which quantified estimates cannot be produced. These include benefits in the areas of defence and security, international leadership, healthcare, and diplomacy. In relation to the key sector of civil aviation the analysis has deliberately taken a cautious estimation approach. Alternative methodologies would deliver £175bn over the next five years, as opposed to the £8.4bn included in the estimate above. There are also very large benefits which accrue globally from the provision of better climate information, which is excluded as this analysis is undertaken from a UK perspective in line with HM Treasury guidance.
The purpose of the study
The Met Office has several distinctive characteristics which make it difficult to compare with other National Meteorological Services (NMS):
