Since the beginning of international climate change negotiations, civil society has worked alongside governments in shaping global agreements and keeping an eye on the implementation (and sometimes the lack of implementation) of these agreements. This report is the first joint product of the Southern Voices capacity building programme. More than 20 climate networks and their member organisations have contributed to the report with their experiences of advocacy on climate change issues. The report presents numerous case studies and policy analyses from a wide range of countries in Africa, Asia, Latin America and the Pacific. The purpose of the report is to share lessons, advice and recommendations from climate change advocates in the Southern Voices programme and beyond.
