On July 6 mayors from around the world came together with representatives of national governments and UN officials at an official side event of the United Nations High-Level Political Forum on Sustainable Development (UN HLPF 2021) to discuss the pressing development challenges related to climate change and related migration in cities, as well as the interrelated Sustainable Development Goals (SDGs), including SDG 10 (Reduced Inequalities) and 13 (Climate Action).

The event was a joint initiative of several organizations working together to address climate-related migration, including the British Council under the Climate Connection program, the C40 Cities-Mayors Migration Council Global Mayors Task Force on Climate and Migration (C40-MMC Task Force), the Global Parliament of Mayors (GPM), the International Organization for Migration (IOM), and the UN Refugee Agency (UNHCR).
