Evaluation of eco-efficiency.

Decoupling trends				Level	Trends
Strong positive decoupling	<0	>0	<−0.5	A: excellent	Economic growth increases while pollution decreases at a rate not less than half the rate of economic growth
Weak positive decoupling	<0	>0	>−0.5	B: very good	Economic growth increases while pollution decreases at a rate less than half the rate of economic growth
Expansive decoupling	>0	>0	<1	C: satisfactory	Economic growth increases while pollution increases at a rate not higher than the rate of economic growth
Declining decoupling	<0	<0	>1.2		Economic growth decreases while pollution decreases at a rate more than 1.2 times the rate of economic growth
Expansive negative decoupling	>0	>0	>1	D: poor	Economic growth increases while pollution increases at a rate higher than the rate of economic growth
Declining negative decoupling	<0	<0	<1.2		Economic growth decreases while pollution decreases at a rate less than 1.2 times the rate of economic growth
Strong negative decoupling	>0	<0	<0	E: unsatisfactory	Economic growth decreases while pollution increases
