a This represents reported incidents occurring within BP’s operational HSSE reporting boundary. That boundary includes BP’s own operated facilities and certain other locations or situations. b DAFWCF and RIF are the annual frequency per 200,000 hours worked. c We report tier 1 process safety events, which are losses of primary containment of greatest consequence – causing harm to a member of the workforce, costly damage to equipment or exceeding defined quantities. Tier 2 events are those of lesser consequence. d Loss of primary containment is an unplanned or uncontrolled release of oil, gas or other hazardous materials from a tank, vessel, pipe, truck, rail car or other equipment used for storage, separation, processing or transfer. Historical and current data for the LOPC metric was restated in 2017 to exclude incidents where there is a safe release of gas to the atmosphere from our US Lower 48 operations, from a hung dump valve in a remote location. e Oil spills are defined as any liquid hydrocarbon release of more than, or equal to, one barrel (159 litres, equivalent to 42 US gallons). f The 2016 and 2017 figures are based on our new definition which aligns with industry practice. g Comprises 100% of emissions from activities that are operated by BP. Data for emissions on an operational control basis was not reported in 2013. h This includes the methane emissions from our operations where gas goes to market as a percentage of that gas – accounting for more than 90% of methane emissions from our operated oil and gas assets. We do not include methane emissions that result from gas that is only reinjected, recycled or associated with assets where BP does not produce the gas. Data was not reported prior to 2016. i Previously referred to as real sustainable reductions (RSRs). This measure reflects actions taken by our businesses that reduce their GHG emissions. See page 13. j Indirect emissions are those associated with the purchase of electricity, heat, steam or cooling into our operations. k We report the total hydrocarbons flared from our upstream operations. l Comprises our share of BP's consolidated entities and equity accounted entities, other than BP's share of Rosneft. m Based on BP’s total reported production of natural gas, natural gas liquids and refinery throughputs. n Based on BP’s total ethanol production and wind generating capacity. The 2017 figure decreased primarily due to the divestment of two wind farms and lower wind power generation overall in the US. o This includes dividends paid in cash and scrip dividends. p Water consumption intensity and mass of produced water were not reported in 2013. q Includes employees who are group leaders, senior level leaders or in other management positions. r The 2013-16 figures have been restated as our calculation now divides the number of UK and US racial minorities by the total population of these nationalities, instead of the total number of group leaders. s Figures for 2013-16 have been amended. t These figures relate to non-retail employees only. In 2017 voluntary turnover (resignations and retirements) was 4%. u Any employee, contractor or other third party can contact our confidential helpline, OpenTalk. v This excludes dismissals of staff employed at our retail sites.
