Climate Change

IUCN engages on this issue from multiple perspectives, from assessing the risks that climate change poses to biodiversity, to advancing practical nature-based solutions centred on the better conservation, management and restoration of the world’s ecosystems

How we engage

IUCN assesses the impacts of climate change on species and ecosystems. Through its work on ecosystem-based mitigation, adaptation and disaster risk reduction, it also highlights the important role of nature-based solutions to climate change. It also works to ensure that climate policy and action are gender-responsive, socially inclusive and take into account to the needs of the most vulnerable.
