The Government has made no assessment of the direct relationship between the North sea oil and gas tax regime and the sector's UK employment base. The latter is influenced by a number of factors, including the management and procurement decisions made by individual companies. Assessments of any anticipated investment effects of changes to the oil and gas tax regime in the forecast period are included in the policy costings for such measures which are certified by the Office for Budget Responsibility. The package of oil and gas measures which the Government introduced in 2012 is expected to increase investment over the forecast period. Following these measures, we have already seen a number of significant new projects being announced, which are together expected by the industry to support thousands of UK jobs.
