Following the progress made under the Millennium Development Goals, which guided global development efforts in the years 2000-2015, the world's governments are currently negotiating a set of Sustainable Development Goals (SDGs) for the period 2016-2030.

The MDGs focused on ending extreme poverty, hunger and preventable disease, and were the most important global development goals in the United Nations' history. The SDGs will continue the fight against extreme poverty, but will add the challenges of ensuring more equitable development and environmental sustainability, especially the key goal of curbing the dangers of human-induced climate change.

But will a new set of goals help the world shift from a dangerous business-as-usual path to one of true sustainable development? Can U.N. goals actually make a difference?
