Climate change has been described as the biggest threat to global health in the 21st century. Last year’s UN Climate Change Conference in Glasgow, COP26, saw large-scale mobilisation in the UK across a wide range of civil society and led to the creation of the COP26 coalition. This coalition included environment and development NGOs, trade unions, grassroots community campaigns, faith groups, youth groups, migrant and racial justice networks — to name a few. The unifying ambition has been to highlight the intersectionality of climate justice and how this issue shows the need for systemic change in our current political and economic systems.
