This Handbook aims to give Parliamentarians and other decision-makers a concise overview of where we stand in the process to design a new global development agenda and how they may interact and influence the sustainable development agenda. Priority will be laid on the role and contribution of Parliamentarians in promoting, advancing and implementing the sustainable development goals with a focus on environmental sustainability in the post-2015 development agenda. The Handbook looks at how Parliamentarians can create ownership for these goals at national level and within their constituencies and provides concrete and hands-on examples of what Parliamentarians can realistically do at this stage of the process and beyond.
