This guide supports HelpAge staff and network members in using Agenda 2030 to advance older people’s rights and inclusion in development policy and practice. It explains how global development must meet older people’s needs and rights if it is to be sustainable and provides key arguments to make this case with policy makers. The 2030 Agenda for Sustainable Development is the world’s plan to end poverty, reduce inequalities and tackle climate change. Inclusion is at the heart of this agenda, with a key pledge to leave no one behind and reach the furthest behind first. These ideals align with HelpAge’s vision for 2030 of a world where every older person leads a dignified, healthy and secure life.
