The alliance was originally known as the Population and Climate Change Alliance (PCCA), as members first came together to raise awareness of the linkages between population and climate change, when the alliance was particularly active around the Copenhagen Climate Change Summit (COP15) in October 2009.
In 2011 members came together during preparations for the 2012 Rio+20 UN Conference on Sustainable Development. The alliance undertook a comprehensive advocacy programme to promote a focus at the summit on the links between population dynamics, sexual and reproductive health and rights, and sustainable development, and in the emerging post-2015 framework. This included a strong presence at the Rio+20 summit and prior informal negotiations, and work to influence the outcome document The Future We Want. As part of this work the alliance grew to encompass additional NGOs.
In late 2012 the decision was taken by members to rename as the Population and Sustainable Development Alliance; a name which reflects the more recent, wider focus of the alliance, not only on the links between population, SRHR and climate change but also on other social, environmental and sustainable development issues. Since then, building on our work at Rio+20, the main purpose and strategic direction of the alliance has been to ensure prioritization of population dynamics and SRHR in the Sustainable Development Goals and post-2015 international development agenda. This current work programme has seen the alliance continue to grow, particularly with the addition of several new Southern members.
