Our certificate

ONCRA is an initiative of The Climate Cleanup Foundation and stands for Open Natural Carbon Removal Accounting. ONCRA is dedicated to removing CO2 from the atmosphere, a process known as Carbon Dioxide Removal (CDR). Our bamboo plantation in Uganda serves as a natural removal method, harnessing the power of plants. In collaboration with ONCRA, we have calculated how much CO2 our bamboo plantation can extract from the atmosphere. For this established quantity, we can issue carbon removal certificates, also known as carbon credits.

How were our carbon removal certificates

ONCRA follows a strict approach to certify our bamboo plantations. There is a lot of greenwashing in today's world. So ONCRA - and we, of course - aim to stay away from this.

Amount of bamboo

First, we calculated how much bamboo can be grown on our plantation. An estimate was also made of the expected amount of bamboo to be harvested.

CO2 storage in the soil

Bamboo stores CO2 in the plant itself as well as in the soil. Hence, we calculated the amount of CO2 present in the ground before and after bamboo planting. This allowed us to determine how much CO2 our bamboo plants can store in the soil. CO2 storage in the ground is re-measured every 4 years to monitor if the actual storage aligns with the calculation.

Original state of the area

We also assessed the condition of the plantation before we began planting bamboo. We determined how much CO2 was already stored in the ground due to the previous vegetation. A systemic approach requires subtracting the previous carbon storage potential from the storage potential of our bamboo plantation.

Bamboo harvesting

Bamboo is currently growing on our plantation, but what happens to the bamboo? Once the bamboo plants mature (which varies depending on the bamboo species), typically after 4 to 5 years, we can start annual harvesting. This is one of the unique characteristics bamboo has compared to trees. A bamboo plant has a long lifespan, and we can harvest them every year for up to 100 years. From the harvested bamboo, we can create bamboo products. Only the long-term CO2 storage, such as in construction materials, is considered. When the time comes, we calculate how much CO2 remains stored in the bamboo products we have created.

Local emissions

Nothing is overlooked in the certification process. We also calculated how much CO2 is locally emitted to maintain the plantation. This includes harvesting mature bamboo, transporting employees to and from the bamboo plantation, and maintaining the plantation. We minimize the use of heavy agricultural machinery and involve only local residents in the project. The cultivation of bamboo plants is also carried out by us with the assistance of the local population, keeping emissions to a minimum and providing local employment.

Risk percentage

We have done everything in our power not to issue more credits than is actually possible. It is possible that a future harvest may be disappointing or that less bamboo grows than estimated. To account for this, a risk percentage is considered. ONCRA mandates this consideration to accommodate unforeseen circumstances.

What does it mean for you

We all

We are very proud that our plantation in Uganda is certified by ONCRA for removing CO2 from the atmosphere. This way, we play our part in the fight against climate change. Do you have questions about our certification or are you curious about what we can do for your CO2 emissions?
