FAQ
Unlike other carbon credit providers, we use technology like AI or Big Data in order to thoroughly analyse more than 600 data points in every project. That enables us to offer only the top 5% of projects around the world.
Based on your requirements of impact projects like regionality, social impact or price we then chose the perfect portfolio of 3-5 projects of this top 5% pool. Furthermore we offer every customer our buyer protection, for extra safety - no one in the DACH region can beat this.
The minimum requirement for us to even consider a project is official registration with standards such as the Gold Standard, Verra and Puro.earth. This is followed by our five-step quality verification through Sustainability Integrity Index (SII), which ensures that all carbon credits are of the highest integrity. Each project is analysed using 600+ data points, including assessments from independent rating agencies such as Sylvera, BeZero and Renoster. This means that only the top 5% of climate projects will be offered to companies.
Senken offers a diverse portfolio of high-quality climate protection projects that either avoid (Avoidance) or remove (Removal) emissions.
We curate an Oxford-compliant portfolio for you comprising both nature-based solutions (NbS) such as Afforestation and Reforestation, regenerative agriculture, and peatland rewetting, as well as technology-based solutions (TbS) such as biochar, enhanced weathering, and Direct Air Capture. Each project undergoes comprehensive credibility assessment to ensure maximum climate and social impact.
A defensible, Oxford-aligned portfolio typically costs at least €25 per tonne, reflecting a strategic mix of:
- High-quality reduction credits (€8–€25/tonne) from nature-based projects
- Carbon removal credits (€20–€400/tonne) from technology and nature-based removal projects like biochar, enhanced weathering, or regenerative agriculture
For companies procuring more than 1,000 tCO2 annually, we work as your strategic partner to structure cost-effective, audit-ready portfolios with transparent pricing and full contracting execution. Budgets typically start around €100,000 depending on emissions and compliance requirements.
For smaller purchases, use Senken Checkout to access pre-vetted, high-integrity projects in minutes.
