Impacts

> 80 %

of ecological processes that form the foundation for life on Earth are impacted by climate change

Solutions

37 %

of the mitigation needed between now and 2030 to meet the 2°C Paris goal can be provided by nature-based solutions

Communities

~ 25 %

of the world’s tropical forest carbon is managed by Indigenous Peoples and local communities


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.
