Quantitative performance indicators have been chosen, with external input, to reflect the most important sustainability issues for BP. Data is reported here only from operations under BP operational control, except for GHG emissions. We use consistent processes that seek to provide acceptable estimates to enable year-to-year comparisons.
DAFWCF and RIF are the annual frequency per 200,000 hours worked.
Oil spills are defined as any liquid hydrocarbon release of more than or equal to one barrel (159 litres, equivalent to 42 US gallons).
Tier 1 process safety events refer to losses of primary containment, from a process, of greatest consequence - causing harm to a member of the workforce or costly damage to equipment, or exceeding defined quantities. This is as defined by the American Petroleum Institute process safety indicator pyramid.
This year we are also disclosing tier 2 process safety events for the first time.
This data does not include the oil spill volume from the Deepwater Horizon incident. The US government and third parties have announced various estimates of the flow rate or total volume of oil spilled from the Deepwater Horizon incident. The multi-district litigation proceedings pending in New Orleans will address the amount of oil spilled. See BP Annual Report and Form 20-F 2012 for information about the volume used to determine our estimated liabilities.
Direct GHG emissions are the physical emissions from operations. Emissions represent all consolidated entities and BP's share of equity-accounted entities except TNK-BP.
In 2010, we did not report on GHG emissions or flaring associated with the incident or response. We have since estimated the gross CO2 equivalent emissions from response activities to be approximately 481,000 tonnes. We have estimated the gas flared during the response to be approximately 56,000 tonnes. We have not resated our 2010 numbers since our practice is only to restate historical emissions for material inaccuracies.
Indirect GHG emissions are a consequence of the import by operations of steam, electricity and heat from third-party sources. Emissions represent all consolidated entities and BP's share of equity-accounted entities except TNK-BP.
Based on BP's total reported production of natural gas, natural gas liquids and refinery throughputs.
Includes $1,753 million environmental expenditure costs relating to the Gulf of Mexico oil spill.
Minor amendments have been made to 2011
Employees are defined as individuals who have a contract of employment with a BP group entity.
Employee figures as at 31 December.
These figures relate to non-retail employees only. In 2012 voluntary turnover (resignations and retirements) was 5%.
Minor amendments have been made to comparative periods 2010-2011.
Combined basis of subsidiaries and equity-accounted entities, excluding acquisitions and disposals.
Petrochemicals production reported within Refining and Marketing. Minor amendments have been made to comparative periods.
Replacement cost profit or loss reflects the replacement cost of supplies. The replacement cost profit or loss for the year is arrived at by excluding from profit inventory holding gains and losses and their associated tax effect. Inventory holding gains and losses represent the difference between the cost of sales calculated using the average cost to BP of supplies acquired during the year and the cost of sales calculated on the first-in first-out method, after adjusting for any changes in provisions where the net realizable value of the inventory is lower than its cost. Inventory holding gains and losses, for this purpose, are calculated for all inventories except for those that are held as a part of a trading position and certain other temporary inventory positions. Replacement cost profit for the group is a non-GAAP measure.
