"Green" must be understood as "sustainable".
means human society
in the balance with nature.
The balances are maintained if a resource is not consumed at a higher rate than needed for regeneration.
"Towards a Green Economy - A Synthesis for Policy Makers", UNEP 2011 (PDF 3 MB, new window)
Note: The "Green Economy" according to UNEP allows continued growth, increasing material well-being and even enhancing nature by so-called "green growth".
The report's leading authors yet have to understand that growth is always material and that growth therefore increases the speeds at which humanity is depleting the planet and growing towards final resource wars and collapse.
Ernst-Ulrich von Weizsäcker on "decoupling". Achim Steiner at slide 63 [PDF 4.8 MB]
"Decoupling" resource use from economic growth is one of the fallacies of economic theories.
Also note, for example, von Weizsaecker's fallacies about I=PAT. He claims Technology is the “decoupling factor” (slide 30). In reality, Technology is increasing the speeds of resource use, so it's a magnifying factor. In principle T is already included in A because more technology requires more resources. But T has been taken separately because of its additional effect. If T had been a reducing factor it should have been in the denominator of the equation.

"What is the IPAT Equation, or I = P X A X T?
One of the earliest attempts to describe the role of multiple factors in determining environmental degradation was the IPAT equation1. It describes the multiplicative contribution of population (P), affluence (A) and technology (T) to environmental impact (I). Environmental impact (I) may be expressed in terms of resource depletion or waste accumulation; population (P) refers to the size of the human population; affluence (A) refers to the level of consumption by that population; and technology (T) refers to the processes used to obtain resources and transform them into useful goods and wastes. The formula was originally used to emphasize the contribution of a growing global population on the environment, at a time when world population was roughly half of what it is now. It continues to be used with reference to population policy.
Holdren generally conclude that technology can
delay certain trends but cannot avert them" (p. 16)
