Human Development Index is one of the (if not the) most widely used measure of well-being, still missing, however, an "environmental dimension" (as suggested during the Rio+20-United Nation Conference on Sustainable Development, as part of Millennium Development Goals post-2015). This paper tackles this issue and introduces an original quantitative measure, named Environmental Human Development Index. The proposed index augments the Human Development Index with the Environmental Performance Index (a complete indicator of environmental quality of countries and a benchmark of policy goals achievement). The paper eventually simulates a country ranking using the new index.
