The Global Sustainable Development Report (GSDR), requested by Governments at Rio+20, is the first and only comprehensive, global report on sustainable development. The present prototype global sustainable development report is the result of a collaborative effort of more than twothousand scientists and 50 staff from 20 UN entities from all world regions. The report illustrates a range of potential content and discusses potential overall directions for the Global Sustainable Development Report. The report maps sustainable development assessments and related processes, and identifies key remaining challenges: to eliminate poverty and hunger; to feed, nurture, house, educate and employ the global population; to ensure peace, security
and freedom; and to preserve the Earth’s basic life support systems.The report sketches an alternative sustainable development pathway for the future. It shows that, if we significantly adjust our current patterns of consumption and production, we can help build a more sustainable world in 2050.
