International Day of Climate Action – 24 October 2026

The International Day of Climate Action is held annually on 24 October and is dedicated to raising awareness and taking action against climate change. The day brings together people, organisations and initiatives worldwide to draw attention to the consequences of global warming and the measures needed to mitigate these effects. From local campaigns and educational activities to climate marches and sustainable initiatives, the day offers an opportunity to reflect on the choices that help reduce greenhouse gas emissions. The day emphasises that climate change is not just an environmental issue, but also affects nature, the economy and society. Organisations use the International Day of Climate Action to share knowledge, highlight solutions and inspire people to take action themselves, such as saving energy, making transport more sustainable and supporting sustainable development.
