How functional economy would be an environmental economy? Mode of endogenization of environmental issues in functional economy

How functional economy would be an environmental economy? And more particularly: What is the mode of endogenization of environmental issues in Functional Economy? This paper reveals the ambiguity of environmental issues integration in Functional Economy through discussion of three proposals: environment is consecutive to Functional Economy; environment is necessary to Functional Economy, and Functional Economy is not correlated to environment. Our research methodology uses business models to evaluate if Functional Economy leads to environmental performances improvements. Business models typology reveals different levels of Functional Economy implementation. Then a correlation between those levels of Functional Economy integration and environmental issues is discussed. High-level Functional Economy has indeed a positive impact on environmental performances (for example companies with an “activist approach”) and low-level Functional Economy (still targeted on the good production) does not lead to environmental improvements. This research also reveals that economical issues drive Functional Economy implementation rather than environmental ones.
