Why partner with Callirius

There is a shortage of funding for high-quality climate projects in the voluntary carbon market. This is because the private sector is hesitant to finance projects due to lacking regulations and transparency. 

To solve this issue, Callirius offers your high-impact climate projects to corporate and institutional investors in our broad network. We first want to understand your needs to connect you to the right partners.
