Governments can fully develop the potential of these new markets.First, they can set high targets for reducing carbon emissions and targets for saving and reusing energy.Besides, stronger arrangement of public resources like forests can also help to speed up the development.Finally, governments can avoid the huge expenses that are taking us in the wrong direction, and redirecting some of those expenses can accelerate the change from traditional model to a sustainable one.
