Total recordable injury frequency
Definition: The number of fatalities, lost-time injuries, cases of alternative work necessitated by an injury and other recordable injuries, excluding first-aid injuries per million working hours.
Developments: The total recordable injury frequency (including both StatoilHydro employees and contractors) decreased from 6.0 in 2006 to 5.0 in 2007. The frequency for StatoilHydro employees was 3.5 in 2007, the same as in 2006, while the frequency for our contractors decreased from 7.9 in 2006 to 6.1 in 2007. |

Lost-time injury frequency
Definition: The number of lost-time injuries and fatal accidents per million working hours.
Developments: The lost-time injury frequency (including both StatoilHydro employees and contractors) was reduced from 2.1 in 2006 to 2.0 in 2007. There has been an increase for StatoilHydro employees, from 1.6 in 2006 to 1.7 in 2007, and for our contractors the lost-time injury frequency decreased from 2.4 in 2006 to 2.2 in 2007.

Serious incident frequency Definition: The number of incidents of a very serious nature per million working hours. An incident is an event or chain of events which 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 where all undesirable incidents are categorised according to the degree of seriousness, and this forms the basis for follow-up in the form of notification, investigation, reporting, analysis, experience transfer and improvement.
Developments: The serious incident frequency (including both StatoilHydro employees and contractors) improved from 2.2 in 2006 to 2.1 in 2007. |
|
Sickness absence Definition: The total number of days of sickness absence as a percentage of possible working days (StatoilHydro employees).
Developments: The sickness absence in StatoilHydro has been stable at 3.5% for the last three years. |

Oil spills Definition: Accidental oil spills to the natural environment from StatoilHydro operations (in cubic metres). All accidental oil spills reaching the natural environment from StatoilHydro-operated activities are included in the figure. However, spills that did not reach the natural environment have also been included for downstream market operations before 2004.
Developments: The number of accidental oil spills was 387 in 2007, compared to 365 in 2006. The volume of accidental spills has increased from 181 cubic metres in 2006 to 4,989 cubic metres in 2007. The figure shows the volume of oil spills in cubic metres. There were two significant oil spills in 2007. One spill of 4.400 cubic metres at Statfjord A on 12 December and one spill of 441 cubic metres at Mongstad refinery on 7 September.

Carbon dioxide emissionsDefinition: Total emissions of carbon dioxide in million tonnes from StatoilHydro-operated activities.
Developments: Carbon dioxide emissions have increased from 12.9 million tonnes in 2006 to 14.6 million in 2007. The main reason for the increased CO2 emissions is the extraordinary flaring at the Snøhvit plant at Melkøya as a result of start-up problems.
Carbon dioxide emissions include CO2 from energy and heat production in own plants, transportation of products, flaring, rest emissions from carbon dioxide capture and treatment plants, process-emission and also emissions from own plants as a consequence of exported energy. Indirect emissions as a consequence of imported energy are excluded.

Nitrogen oxide emissions
Definition: Total emissions of nitrogen oxides in thousand tonnes from StatoilHydro-operated activities.
Developments: Emissions of nitrogen oxides have increased from 47.7 thousand tonnes in 2006 to 49.4 thousand tonnes in 2007. The flare at Melkøya during start-up has increased the nitrogen oxide emissions significantly. However, due to new guidelines the nitrogen oxide emission factor for offshore flare has been adjusted. This reduces the reported emissions from offshore flare in general, making the total increase smaller than for energy consumption and CO2 emissions.
Nitrogen oxide emissions embrace all emission sources and include Nitrogen oxides from energy and heat production in own plants, transportation of products, flaring and treatment plants.

Energy consumption Definition: Total energy consumption in terawatt-hours (TWh) for StatoilHydro-operated activities.
Developments: Energy consumption has increased from 62.4 TWh in 2006 to 69.8 TWh in 2007. The main reason for the increased energy consumption is the flaring at the Snøhvit plant at Melkøya as a result of start-up problems. In other respects, the energy consumption has been relatively stable. The business area Natural Gas has seen a small reduction due to transfer of responsibility of operations for receiving terminals at the European Continent from Statoil to Gassco. Also, from 2006, StatoilHydro took into consideration loss of energy production from external suppliers and losses related to transfer of energy when calculation total energy consumption.
The main reason for the increased energy consumption is the flaring at the Snøhvit plant at Melkøya as a result of start-up problems.
Energy consumption includes energy consumed in producing the facility's deliveries or by performing an activity, and includes gross purchases of electricity and thermal energy (steam), energy from gas and diesel-fuelled power generation, unused energy from flaring and sold/delivered energy. Energy based on the use of fossil fuels is deemed to be energy input. Prior to 2006, energy consumption was based on net purchase of electricity.

Recovery rate for non-hazardous waste Definition: The recovery rate for non-hazardous waste comprises non-hazardous waste from StatoilHydro-operated activities and represents the amount of non-hazardous waste for recovery in relation to the total quantity of waste.
Developments: There has been an increase in the amount of non-hazardous waste. Much of this increase is due to inclusion of Marketing/Energy & Retail in the reporting (2,4700 tonnes) and new activity in the Gulf of Mexico. The recovery rate is reduced because there is no recovery solution on the GoM. Energy & Retail also report no recovery. This is correct according to the definitions, but does not take into account the fact that E&R delivers through municipal systems where there is often in the next step of a recovery system. The recovery factor for 2007 is 41%, a decrease from 79% in 2006. The recovery factor without Energy & Retail included is 64%.
The quantity of non-hazardous waste for recovery is the total quantity of non-hazardous waste from the plant's operations which has been delivered for reuse, recycling or incineration with energy utilisation.
