The ambition of this chapter is to present a sustainability economics largely compatible with normal ideas of democracy. Rather than rely on expertise and technocracy as in neoclassical enonomics, different actors in the economy are made visible with their ideological orientation. How do they understand sustainable development for example? Institutional inertia as well as institutional change is discussed. It is argued that the dominance of neoclassical economics with connected ideology is one of the main explanations of the current ecological crisis.
