We Live Sustainability

For us, sustainability means making responsibility tangible. Through our regional biochar production, we have established a cycle that demonstrably removes CO2 from the atmosphere—not just on paper, but in reality. Behind every gram of our biochar lies our unwavering commitment to genuine climate protection—without detours, right here on the ground, and secured in the soil for millennia. When you choose Sonnenerde, you’re not just buying a certificate; you’re buying the certainty that you’re making a genuine, lasting contribution to preserving the foundations of our existence.

20 Years of Research

The production of premium biochar allows for no shortcuts. The technology that has been proven to remove CO2 from the atmosphere today is the result of over 20 years of dedicated research and development. For nearly two decades, we at Sonnenerde have been optimizing the thermal processes of pyrolysis to create biochar that meets the highest scientific standards and binds carbon permanently and safely. This in-depth understanding of the production process makes our facility one of the most efficient in Europe today—and our certificates the gold standard in CO2 offsetting.

Highest Quality

We don’t just produce biochar; we meet the strictest European standards. Our facility and our biochar are certified under the rigorous European Biochar Certificate (EBC). We have not only met the basic standards but have achieved the highest premium classes: EBC-Agro, EBC-AgroBio, and even EBC-FutterPlus. This means that our biochar is so pure, free of contaminants, and of such high quality that it is even permitted for use in strictly regulated organic agriculture and animal feed.

Biochars certified with EBC-Agro meet all requirements of the latest EU fertilizer Regulation (EU) 2019/1009.

Biochar: The Great Hope

Not all CO2 storage solutions are created equal: While most approaches are risky or only short-term, one method offers the perfect solution to the climate crisis.

❌ CCS (Carbon Capture & Storage): Injecting CO2 deep underground is extremely energy-intensive, potentially risky (leaks), and offers absolutely no environmental benefit.

❌ Biomass (e.g., reforestation): Forests are only temporary storage sites. If the wood rots or the forest burns, the stored CO2 is immediately released back into the atmosphere.

❌ Humus formation: While extremely important for the soil, the CO2 bound in humus is lost back into the air in conventionally managed agriculture.

✅ The solution: Biochar: It has none of these drawbacks! The carbon is chemically stabilized for millennia by our carbon-binding process. It can no longer escape and additionally acts in the soil as a highly effective sponge for water and nutrients.

Sonnenerde Premium Certificates

We engage in Carbon Dioxide Removal (CDR)

  • Guaranteed Permanence: Our high-tech pyrolysis process converts regional biomass into biochar. This stabilizes the carbon at the molecular level, ensuring it remains securely bound in the soil for thousands of years—resistant to decomposition or fire.
  • Active Reduction: You pay for real, measurable carbon removal from our atmosphere. Every ton is physically bound in the biochar.
  • No double counting: We guarantee that there is no double counting with us. Each certificate is uniquely assigned and is retired from the official registry after sale. Anyone who purchases climate credits from us receives 100% genuine, physically achieved CO2 reduction that is fraud-proof and fully documented.
  • Highest standards: Our entire production process and the resulting biochar are subject to the strictest controls in the world. We are officially certified by CSI (Carbon Standards International).

CO2 sink statistics

Global C-Sink Registry

When it comes to CO2 sink certificates, the highest quality is essential. That is why we operate exclusively in accordance with the strict guidelines of the Global C-Sink Standard—the world’s most important and leading standard for carbon sinks. To guarantee you complete transparency and security, every credit is officially and fully documented in the Global C-Sink Registry.
