A score of 1-2 is given to countries described as an "unsustainable mixed system", while those with overall scores in the range of 2-3 fall in the "near sustainability" group.
Ocena od 1 do 2 daje se zemljama u kojima postoji sistem tzv. “mešovite neodrživosti”, dok one sa ocenom između 2 i 3 spadaju u grupu “blizu održivosti”.
