The Climate Action Community is an IES Challenge-Led Community focussed on championing the work of professionals in the environmental sciences in climate action, promoting the work of experts and evidence around climate change and driving change to ensure adaptation and mitigation measures are accurate, ambitious and achievable. The Community champions interdisciplinary working and a systems approach to the interlinked crises of climate change, biodiversity loss and pollution.

This Community was established as the time-limited COP26 Community and transitioned into the permanent Climate Action Community after COP26.
