Carbonstack raises seed funding

The start-up wants to compensate CO2 emissions of companies with regional reforestation projects.

Hamburg-based start-up Carbonstack receives half a million euros in seed funding. The capital comes from Swedish business angel Per Liljenqvist.

"By investing in our technology, we can scale offsetting opportunities faster, document them more accurately and attract new customers," says co-founder and CEO Julian Kakarott. He co-founded Carbonstack 2022 with Noah Winneberger, Jesper Kolk and Jann Wendt. The start-up develops regional reforestation projects for companies that want to offset their CO2 emissions. According to its own information, the start-up has already planted over 45,000 trees in Germany this spring. The focus would be on forest areas that are already suffering from climate change. Currently, the company is planning projects in the Harz Mountains and in North Rhine-Westphalia.

The founding team has all forests monitored with satellite imagery and documents the compensation amounts on a blockchain, he said. "Our goal is to make this compensation as measurable and transparent as possible," Kakarott said. With blockchain technology, he said, companies' carbon offsets can be documented in a tamper-proof way and the impact can be made transparent.
