0.00014% Given the varied scale and types of operations on the UKCS, benchmarked rankings may not truly reflect some individual environmental performances, but allow a general understanding to be developed. of production have been falling since 2013 The analysis is presented anonymously with each company allocated a letter in each category. A single operator’s performance cannot be tracked from one graph to another. Operators are informed of their rankings in each category, without t e ability to attribute the environmental performance of other companies. The average concentration of oil in produced water fell in 2016 The total volume of produced water discharged to sea under permit fell by 6 per cent In Summary I mp oving asset st wardship has led to a decrease in produced water and drill cuttings discharged to sea, and GHG emissions across the UK offshore oil and gas sector in 2016 (see section 3). These gains in environmental performance, during a period of significant production i reas , highlight the industry’s commitment to effectively managing its emissions and discharges to the environment. Each year, Oil & Gas UK carries out a benchmarking exercise for operators reporting data into EEMS to gain an overview of thei individual performance in the context of the overall industry. Areas of concerning or promising performance can be identified, with the aim of achieving better sector-wide performance. to 155 million cubic metres in 2016
