Monitoring Sustainability

The indicators in this sustainability report are complementary to Stena’s annual report. As the Group’s operations differ in nature and therefore have different material topics, the environmental key figures are partly reported by business area. The financial and social indicators are reported at an aggregate level for the Group.

Environmental indicators

Ferry Operations, Offshore Drilling and Shipping

For Stena’s shipping operations, the most important issue in terms of environmental impacts is CO2 emissions. As Stena operates a wide range of vessel types, the environmental indicators are reported in absolute figures for the total fleet. In 2017, total fuel consumption increased, but total distance sailed increased more, and fuel consumption per nautical mile declined by 5.6%. This shows a continuing improvement in fuel efficiency and a corresponding reduction in carbon dioxide emissions. 

Energy consumption 1) 2015 2016 2017
Number of vessels in the report 109 105 111
Total distance sailed (1,000 nm) 2) 6,945 6,919 7,487
Total fuel consumption on vessels (1,000 tonnes) 1,118 1,066 1,084
Total energy consumption on vessels (TJ) 47,097 44,470 45,150
Greenhouse gas emissions 1)  2015 2016 2017
CO2 (1,000 tonnes) 3,484 3,346 3,382
Other emissions 1)  2015 2016 2017
NOx (1,000 tonnes) 76 74 74
SOx (1,000 tonnes) 26 26 24

1) Refers to Ferry Operations, Offshore Drilling and Shipping. The vessels in this report have been limited to those for which Stena has operational control over fuel purchasing, speed etc. Vessels that are leased to external customers are not included. For the 2016 reporting, the formulas for emissions calculation were updated in order to improve precision and quality. The data for 2015 has therefore been retrospectively recalculated in accordance with the updated formulas.  2) For Stena Drilling’s units, distances sailed are not registered.

Stena Property

Stena Property’s largest environmental impact is the consumption of electricity, heating and water in homes and premises. The overall target is to reduce electricity consumption by 30%, and heating and water consumption by 20% between 2010 and 2020. At the end of 2017, electricity consumption had decreased by 40%, heating ­consumption by 15% and water consumption by 6% compared with the 2010 levels. Issues concerning social ­sustainability are also very important for Stena Property.

Energy consumption kwh/m2 25 23 22
Heating consumption kwh/m2 2 2 2
Water consumption m3/m2 129 126 120

  Sustainability objectives 2017 Outcome 2017
Transport Provide drivers with eco-driving training with individual follow-up In progress
Energy consumption Conduct a company-wide energy survey Completed  
  OEE* measurement for energy-intensive resources Completed 
  Energy consumption for solvent cleaning <2.0 kWh/m2 painted surface 1.88 kWh/m2 painted surface (1.93 kWh/m2 painted surface 2016) 
Emissions into air Maintain >90% efficiency for existing solvent cleaners Efficiency of 96%, (95.8% in 2016) 
Waste  Reduce the proportion of waste for destruction The increased production volume in 2017 meant that a reduction of the amount of waste in absolute figures was not achieved. 

OEE = Overall Equipment Effectiveness – a key indicator form easuring production effectiveness or totalt effective equipment performance


  Sustainability objectives 2017 Outcome 2017
Transport Provide drivers with eco-driving training In progress
Energy consumption   As far as possible buy green electricity to all operations Completed
Energy consumption   Reduce energy consumption in stores within the projekt “Energijägarna”  In progress
Product offering Reduce sales of environmentally hazardous products Completed
Work & human rights Continue to use the employer survey for business development In progress

The Shipping Operation's Vessels



Large reductions of SOx emissions through the introduction of the sulphur directive in January 2015. Efforts to reduce sulphur emissions ­continued in 2017 with scrubber installations and increased use of low-sulphur fuel.



The graph shows an indexed average value for the fleet’s fuel consumption per nautical mile in 2017. Consumption in 2017 decreased by 5.6% compared with the previous year. Stena Drilling’s units are not included above.
