Norway’s position in the Environmental Performance Index 2006

In the Environmental Performance Index released last week at the annual meeting of the World Economic Forum, Norway has fallen from second to eighteenth place. The ranking is partially based on a Productivity Overfishing Index, defined as a relationship between biomass production and fish catches in a given area. Research carried out by IMR shows that it is not correct to use this index in the same way in different ocean regions as the transfer efficiency between different levels in the food chain varies widely from one type of ecosystem to another.
