Developments: The total recordable injury frequency (including both Statoil employees and contractors) increased from 4.2 in 2010 to 4.4 in 2011. The frequency for Statoil employees was the same in 2011 as in 2010 (3.3), but the total recordable injury frequency for our contractors increased from 4.8 in 2010 to 5.1 in 2011.

(2) An incident is an event or chain of events that has caused or could have caused injury, illness and/or damage to/loss of property, the environment or a third party. Matrices for categorisation have been established in which all undesirable incidents are categorised according to the degree of seriousness. This forms the basis for follow-up in the form of notification, investigation, reporting, analysis, experience transfer and improvement.

Sickness absence 

Definition: The total number of sickness absence hours as a percentage of planned working hours (Statoil employees) (3).

Developments:  S ickness absence increased from 3.6% in 2010 to 3.8% in 2011. The increase is most significant in our Norwegian operations.

(3) In 2010 and 2011, Statoil calculated sickness absence as a percentage of planned working hours. Previous years' sickness absence was calculated as a percentage of planned working days.

Oil spills

Definition: Unintentional oil spills to the natural environment from Statoil operations (in cubic metres) (4).

Developments:   The number of unintentional oil spills was 376 in 2011, compared with 374 in 2010, and the volume in 2011 was the same as in 2010 (44 cubic metres). 

(4) All unintentional oil spills reaching the natural environment from Statoil operations are included in the figure.

Other spills

Definition: Other unintentional spills to the natural environment from Statoil operations (in cubic metres) (5).

Developments:   The number of other unintentional spills was 146 in 2011, compared with 144 in 2010, and the volume in 2011 was 134 cubic metres compared with 5709 cubic metres in 2010.

CO2 emissions

Definition: Total emissions of carbon dioxide (CO2) in million tonnes from Statoil operated activities (6)

Developments:   Emissions of CO2 have increased slightly from 13.4 million tonnes in 2010 to 13.7 million tonnes in 2011. Emissions from our international operations have increased in 2011 due to increased activities, mainly Leismer (Canada) and Peregrino (Brazil). The emissions from our mid and downstream activities have increased, mainly due to the first year of ordinary operation of the combined heat and power plant at Mongstad. Emissions on the Norwegian continental shelf have decreased due to lower production. CO2 emissions from flaring have decreased from 1.3 million tonnes in 2010 to 1.2 million tonnes in 2011. 

(6) Carbon dioxide emissions include carbon dioxide from energy and heat production, flaring (including well testing/well work-over), rest emissions from carbon dioxide capture and treatment plants and process emissions.

NOx emissions

Definition: Total emissions of nitrogen oxides (NOx) in thousand tonnes from Statoil operated activities (7)

Developments: Emissions of NOx have decreased from 42.3 thousand tonnes in 2010 to 41.4 thousand tonnes in 2011.

(7) Nitrogen oxide emissions include nitrogen oxides from energy and heat production at our own plants, from the transportation of products, flaring (included well testing/well work-over) and treatment plants.

CH4 emissions

Definition: Total emissions of methane (CH4) in thousand tonnes from Statoil operated activities (8) 

Developments:   Methane emissions have decreased slightly from 33.4 thousand tonnes in 2010 to 33.1 thousand tonnes in 2011. Emissions from our international operations have increased due to increased activities, while emissions on the Norwegian continental shelf have decreased by 8.2 % from 2010 to 2011 due to lower production. 

(8) CH4 emissions include CH4 from energy and heat production at own plants, flaring (included well testing/well work-over), cold venting, diffuse emissions and also storage and loading of crude oil. The correction in the 2010 data compared with last year's report is due to missing registration of data for Åsgard A and Åsgard B. Figures at the corporate level from 2009 are verified by external auditors.

nmVOC emissions

Definition: Total quantity of non-methane volatile organic compounds (nmVOC) in thousand tonnes released to the atmosphere from Statoil operated activities (9) 

Developments:  Emissions of  nmVOC decreased from 45.4 thousand tonnes in 2010 to 41.6 thousand tonnes in 2011. The main reason for the reduced emissions is a 50% reduction in loaded volumes of oil from the Gullfaks A platform on the Norwegian continental shelf. 

(9) Includes emissions of nmVOC from energy and heat production, transportation of products, flaring (including well testing/well work-over), cold venting, diffuse emission sources, storage and loading of crude oil and products, and also rest emissions from nmVOC recovery plant. Figures at the corporate level from 2011 are verified by external auditors.

SOx emissions

Definition:  Total volume of sulphur oxides (SOx) in thousand tonnes released to the atmosphere from Statoil operated activities (10) 

Developments:   Emissions of sulphur oxides increased from 1.4 thousand tonnes in 2010 to 3.4 thousand tonnes in 2011. The main reason for the increase in SOx emissions is the start of production at the Peregrino field in Brazil, where diesel is currently used as an energy source.

(10) Includes emissions of SOx from energy and heat production and flaring (including well testing/well work-over). Figures at corporate level from 2011 are verified by external auditors.

Global warming potential (GWP)

Definition: Global warming potential (GWP) is Statoil's share of greenhouse gas emissions from Statoil operated activities and activities operated by others (11)

Developments:   GWP is reported on an equity share basis and has increased from 10.2 million tonnes in 2010 to 10.9 million tonnes in 2011. Equity share CO2 emissions have increased, but equity share methane emissions have decreased .

(11) The unit of measurement is "tonnes of carbon dioxide equivalent". This indicator is calculated based on Statoil's share of emissions of carbon dioxide and methane, using the following formula:[1*(emissions of CO2)]+[21*(emissions of CH4)].

Energy consumption

Definition: Total energy consumption in TWh for Statoil operated activities (12)

Developments:  Total energy consumption has increased from 64.5 TWh in 2010 to 66.5 TWh in 2011. Energy consumption in our international operations has increased in 2011 due to increased activity, mainly from Leismer and Peregrino. The energy consumption at our land-based facilities has increased, while energy consumption on the Norwegian continental shelf has decreased due to lower production.

(12) Energy consumption includes energy from power and heat production based on combustion, unused energy from flaring (including well testing/well work-over and venting), energy sold/delivered to third parties and gross energy (heat and electricity) imported from contractors.

Hazardous waste recovery rate

Definition: The hazardous waste recovery rate comprises hazardous waste from Statoil operated activities and represents the amount of hazardous waste for recovery as a proportion of the total quantity of hazardous waste (14)

Developments:  The hazardous waste recovery rate has decreased from 28.7% in 2010 to 17.2% in 2011.

(14) The quantity of hazardous waste for recovery is the total quantity of hazardous waste from the plant's operations that has been delivered for reuse, recycled or incinerated with energy recovery (the total amount of hazardous waste, excluding hazardous waste sent to an approved deposition facility). The figures at the corporate level from 2009 are verified by external auditors.

Regular discharges of oil to water

Definition: Regular discharges of oil to water in thousand tonnes represent the total amount of oil via regulated or controlled discharges to water environment (both freshwater recipients and sea) from Statoil operated activities (15)

Developments: The amount of regular discharges of oil to water is at a stable level, and was the same in 2011 as in 2010 (1.2 thousand tonnes).

(15) Figures at the corporate level from 2011 are verified by external auditors.
