The Eco-Lighthouse certification is based on a set of general requirements (General Industry Criteria), which apply to enterprises in all industries, and over 50 sets of criteria applicable to specific industries.
The general requirements are available here: General Criteria (PDF)
Industries are classified according to the Norwegian Standard Industrial Classification (SIC2007). To achieve certification under the Eco-Lighthouse scheme, enterprises must satisfy both the General Industry Criteria and the criteria specific to their respective industries.
