Focus on Nature-Based Projects

Callirius focuses on nature-based climate protection projects thanks to their scalability, and positive impacts on the climate, nature, and sustainable development.

Why Tree.ly

Support Sustainable Projects

For Callirius, supporting climate protection projects that are both - regional and effective - is of essential importance. Therefore, Callirius has opted for forest climate protection projects by Tree.ly, as their high-quality and effective work has been proven to make the forest ecosystem more climate-resilient.

Earmarked use of funds

The money goes directly to the forest owners, who reinvest them entirely in the maintenance and care of the forest.

The forest climate protection projects by Tree.ly are local and offer added value for you and your environment.


The Supported Projects

The projects by Tree.ly have successfully passed the quality assessment by Callirius. The science-based methodology, independent validation and verification by TÜV, sustainable project development, restricted use of funds, and transparent communication are just some of the aspects that were decisive for Callirius.

European Project Portfolio

Callirius offers a selection of projects from the Tree.ly portfolio that are customized to the location of the interested party. This way, climate protection can be implemented directly in the region.
