A key goal of mercury policy is the reduction in mercury emissions, particularly to atmosphere. However, it is now recognised that the contribution of anthropogenic and natural emissions to our understanding of the global mercury budget is not sufficiently comprehensive to make accurate and confident assessments.
A recognised knowledge gap hindering the construction of mercury budgets is the release of mercury into the environment from the activities of the oil and gas industry. Consequently, the IKIMP initiative has produced a report synthesizing the knowledge available in the public domain to inform UK policymakers and regulators, and other stakeholders.
The report considers:
A key, overarching conclusion of the study is that the paucity of data available in the public domain means that there are large uncertainties in the quantities of mercury contained in the oil and gas processed and used in the UK, and in consequent releases to the environment. These difficulties of estimation are exacerbated by substantial variations in the mercury contents of oil and gas derived from different sources.
The final report is available for download.
