The year 2013 set a pace and raised the bar on what IUCN can achieve in a short time. The Union helped nations use natural defences to boost resilience against disasters, showed companies how to value natural capital, mobilized governments to curb the recent spike in illegal wildlife trade, and produced the world's first gender and environment index. As the global voice of nature and sustainability, IUCN helped craft the Sustainable Development Goals and continued to maintain strong links with multilateral environmental agreements and their Secretariats. We were delighted to welcome a new Framework Partner, the Republic of Korea, and we also stabilized the financial situation. This annual report documents the highlights and the achievements of the Union in 2013.
