The Millennium Development Goals (MDG) were adopted in 2000 and were the UN's vision of a new anti-poverty partnership. The eight main goals set targets for 2015. According to the UN ( http://www.undp.org/content/undp/en/home/sdgoverview/mdg_goals.html) "the 15-year effort has produced the most successful anti-poverty movement in history ... Yet the job is unfinished for millions of peopleŚwe need to go the last mile on ending hunger, achieving full gender equality, improving health services and getting every child into school. Now we must shift the world onto a sustainable path." The page also provides a link to the final MDG report.
The Sustainable Development Goals (SDG) followed the MDGs immediately. They expanded the number of main goals to 17, each with sub-goals, these are to be implemented by 2030. According to the UN's main SDG page (https://www.un.org/sustainabledevelopment/sustainable-development-goals/) "the Sustainable Development Goals are the blueprint to achieve a better and more sustainable future for all."
