Energy Consumption


Energy consumption per employee 7.4  MWh 

Due to problems with data collection 5 locations with more than 40 employees are not included in the energy consumption statistics. In 2014 a total of 77 locations comprised of 11 928 employees reported energy consumption. Based on number of employees by the end of 2014, the environmental reports represent approximately 76 % of the Group. Total reported energy consumption for 2014 was 87.5 GWh.  23.4 GWh was consumed by locations that did not participate in the environmental reporting for 2013. Locations that did report energy consumption in 2013 but not in 2014 are include in the 2013 figures with  0.3 GWh. Together, the locations that reported for both years experienced an increase in the  reported energy consumption of approximately 4.8 % compared to 2013. There is an increase in district heating from external suppliers of 422% compared to 2013, this is mainly due to reporting from locations that did not report last year. 

Renewable energy on site has decreased to 2.9 GWh, down 29% compared to 2013. This is due to changes in use of the heat pump at Høvik which was earlier used both for heating and cooling, but which is now only used to produce heat. Water for cooling, temperature 7-9 degrees, is now pumped directly from the sea.  Specific energy consumption decreased to about 7.4  MWh per person in 2014 – down  10,0 %  from 8.2 MWh per person in 2013. This decrease in consumption per employee is affected by an improved energy measuring process for one large location that has reported too high figures in 2013, energy saving initiative at several locations, and underreporting by some of the locations that are reporting for the first time. 

Specifically ordered renewable electricity off-site was 10.1 GWh in 2014 increased from 3.0 GWh in 2013. The locations reporting for the first time in 2014 are the main contributer to this significant increase in consumption of renewable electricity off site. Non-renewable energy produced on-site at the reporting locations increase by about 14 % compared to 2013. This increase relates to the consumption of  6.3 GWh produced by combustion of  gas on site at the locations reporting for the first time in 2014. Together, the locations that have reported consumption of gas for both years have a decrease of 33.3 % in their consumption compared to 2013. The main contributors to this substantial reduction is the test site facilities in Groningen that has not been using  their high natural gas consuming test facilities in 2014, and the Barendrecht office building where significant improvement to the controls of the  HVAC  (Heating, ventilation and air-conditioning) system has been implemented.

Energy-consumption-location
Energy consumption in the reporting locations: Ordered renewable electricity off-site and electricity off-site. Renewable electricity off-site covers renewable electricity from grid that has been ordered specifically by the locations. Electricity off-site covers all other electricity from grid, general electricity from grid delivered when no action has been taken to select the source of energy desired.

Emissions to air from operation at DNV GL’s locations


 The calculated emissions to air include the following sources:
  • Direct emissions (Scope 1): Emissions from operations owned or controlled by DNV GL, including the combustion of oil and gas for the production of heat.
  • Indirect emissions (Scope 2): Emissions from the production of heat or electricity procured by DNV GL, but produced at sites not managed by DNV GL.

The emissions of CO2 equivalents at the reporting locations in 2014 were approximately 26 335,8 tonnes. Locations reporting for the first time represented about 6 196 tonnes of the overall emissions. Locations that did report in 2013 but not in 2014 are included in the 2013 figures with 234 Tonnes. Locations reporting both in 2013 and 2014 showed an increase in CO2 emissions of about 57% compared with 2013. This increase is a result of an increase in reported energy consumption in countries with relatively high emission from energy production, emissions from use of Sulfur Hexafluoride (SF6) gas of 202kg corresponding to 4 484 tonnes CO2 equivalents, and the direct emissions of natural gas of 74 tonnes CO2 equivalents. The SF6 gas is used at DNV GL’s test sites inside customers’ test objects and in DNV GL’s auxiliary breakers. Emissions result both from test failures of the customers’ objects and through handling of the SF6 gas. The emission of this substance is 0,56% of the total usage of SF6 gas at DNV GL’s premises. The natural gas is emitted at a test facility, when the installations are depressurized in case of an emergency shutdown it is blown off into the air. 

The specific emission of CO2 for all the reporting locations increased to 2.2 tonnes of CO2 per person in 2014, up 22% compared to 2013. The CO2 emission per person in 2014 from energy consumption at the reporting locations is 1.8 tonnes same as for 2013.  

Estimated emissions of NOx increased by 13% compared with 2013, due to an increase of gas combustion while emissions of SOx remain 0.

Note: The CO2 emissions have been calculated from the consumption of energy reported by the locations. The recommendations set out in the Greenhouse gas protocol (World business Council for Sustainable Development and World Resources Institute). Indirect emissions from electricity and district heating have been calculated using country specific grid average emissions factors published by the International Energy Agency and retrieved from their data service website (http.//data.iea.org) Direct emissions for SOx and NOx have been calculated using source specific emission factors retrieved from Norwegian Climate and Pollution Agency (Norwegian Emission Inventory 2011) Due to the lack of region and source specific emission factors, the emissions of nitrogen oxides (NOx) and sulphur oxides (SOx) have been estimated at a high level only. SOx and NOx have not been calculated for electricity from grid and district heating.

CO2 emission from air travel

DNV GL has implemented a common global tool accounting for mileage and CO2 emissions related to business flights. Air travel is an integral part of DNV GL’s work, so the intention is not to stop travelling, but rather to increase employees’ awareness of their travel footprints.  It has not been possible to verify the reported figures. The calculated of CO2 emissions from business air travel decreased to 0.92 tonnes per employee in 2014 down from 1.15 tonnes in 2013. This decrease is assumed mainly to reflect underreporting due to delays in implementation of the recording system in the merged organisation.
