How does CO2 compensation work?

Sustainable and verified projects in developing and emerging countries are compensated for avoided or reduced CO2 emissions. The compensation is made through the sale of certificates for CO2 compensation. By purchasing and retiring the verified certificates, you offset your own emissions that could not have been avoided in the past and thus make a contribution to global climate protection.

Individual branding

Customize public pages, like the certificate pages, with your logo and host them on your own domain. Send individually designed e-mails and compensate the calculated emissions with your customers under your brand.

Experience the possibilities in action
