As a service provider, DNV’s operations have limited environmental impact. Nevertheless, DNV will work to improve its environmental performance through energy conservation and waste handling in all countries.
Environmental Management System
In 2006 DNV further developed an Environmental Management System in accordance with ISO 14001, where energy consumption and waste handling are the most important focus areas. This system will be implemented throughout the organisation in 2007.
Energy Consumption
A survey of five DNV offices (Høvik, Rio de Janeiro, London, Singapore and Houston), covering approximately 34 per cent of DNV’s employees, has been conducted in order to map energy consumption and waste handling. The average energy consumption per person in the selected offices was 14 040 kWh in 2006, a decrease from 15 000 kWh in 2005. Of this, 12 per cent was renewable energy produced by a heat pump at Høvik (11 per cent in 2005). When hydropower is included, renewable energy constitutes 77 per cent of consumption (the same level as in 2005).
Waste Handling
The laboratories of DNV Petroleum Services (DNVPS) reported the disposal of 112 tonnes of hazardous waste in 2006 (a decrease from 138 tonnes in 2005), of which 2 per cent (2.37 tonnes) consisted of oil that was burned off to the air.
Travel
Visits to customer sites and offices are an important part of the execution of DNV’s services, including for meetings, audits and surveys, and require travel that has a negative impact on the environment. The fact that DNV is organised with offices located all over the world, and has locally employed staff, reduces the need for air travel. Furthermore, alternatives such as video conferences are used when practical.
