It has been 20 years since the United Nations Conference on Environment and Development, which shone a spotlight on the serious ecological deterioration of our planet and its implications for human well-being, and yet we are still facing the same problems, compounded by new challenges that have resulted from the absence of a global perspective and the limited action taken. Some progress has been made, but we are still far from achieving sustainable development. The United Nations Conference on Sustainable Development (Rio+20) emphasized the great importance of growth (but from the perspective of a green economy), as well as the need for institutional arrangements that foster sustainability.
