This past week saw the Global Goals for sustainable development adopted by world leaders at the United Nations, replacing the Millennium Development Goals (MDGs) which have driven the global development agenda for the past 15 years.

While imperfect, the MDGs were an unprecedented global effort to tackle challenges such as global poverty, lack of access to education and healthcare, environmental degradation, and women's equality.

In a recent blog post, B Team Leader Kathy Calvin explains that many of the major successes in the last 15 years were a result of strong collaboration and partnership across sectors. She tells stories of how adolescent girls are able to avoid marriage and stay in school through partnerships between the government, local communities and activists working to change local laws, and how pregnant women in rural villages are able to get vital health information through their mobile phone, thanks to partnerships between business, government and local groups focused on healthcare for mothers.

Indeed one of the major lessons learned form the MDGs is that the challenges we face are immense and cross-cutting. Partnerships, commitment and energy from all sectors will be key to the success of the Global Goals.
