About CarbonFix

The organisation is led by a group of professionals who are passionate about improving Earth’s climate. CarbonFix invest in climate solutions differently to other organisations as we’re not here to see a return on our investment. Instead, our success is measured by attributable emission reductions – by making a difference.
