Environmental management

In this chapter:

The Volvo Group’s energy consumption was 2,518 GWh in 2012, an increase of 47 GWh compared with 2,471 GWh in 2011. The use of energy was less efficient last year and the energy efficiency index is 8.5 MWh/SEK M, compared with 8.1 MWh/SEK M in 2011. But the 2012 efficiency index is still lower compared to the previous years, following the reduction trend over a longer period. The energy efficiency index in 2011 was exceptionally low mainly due to very high production volumes. Most of the recorded energy usage is for heating and production processes, and approximately 20 percent of energy usage is used at the engine and driveline production facilities.

Approximately 20 percent of energy usage is used at the engine and driveline production facilities.

Emissions of carbon dioxide, nitrogen oxides and sulphur oxides are dependent on the fuel used. The decrease of carbon dioxide emissions despite increasing energy use is a result of change in energy sources.

Reducing energy usage per manufactured unit is a priority target which means both reduced costs and lower emissions. Between 2004 and 2012, energy consumption has decreased by 36 percent and the carbon dioxide emissions by 47 percent per unit produced. Energy efficiency initiatives, such as controlled lighting and ventilation, turning off equipment from idle running and replacing old machinery have contributed to the result.

The environmental requirements for the plants include a mapping of all energy ­consuming processes, implementation of efficiency utilization on a continuous basis and a focus on energy usage in new projects.
