84% of carbon credits have no real climate impact. We help you buy from the 16% that do.
Senken is a carbon credit procurement partner for European enterprises. We screen every project against our 600-point Sustainability Integrity Index (SII) and build your portfolio from the top 5% that pass, so every credit you claim holds up in an audit and in public.
German companies unknowingly spent over €100M on low-impact climate projects.
Bought by German Companies
68% of DAX40 companies bought carbon credits that failed to deliver real impact. Many have already faced greenwashing accusations. For the rest, it's only a matter of time.
We screen this risk out before you buy.Every credit is checked for real climate impact and a clean public record before it reaches your portfolio, so when an auditor or a journalist reviews it later, they find the same answer we gave you upfront.

The audit happens before you buy, not after.
We give you the answers to every question an auditor, a journalist or your board will ask, before the credit is in your portfolio.
We test the impact
We evaluate additionality, permanence and leakage with AI models and geospatial data before a credit enters your portfolio. 95% of credits fail this test.
We check the record
External ratings, press coverage and ICVCM methodology status are all checked before purchase, so your company never appears next to a greenwashing headline.
We hand you the evidence
Every credit comes with CSRD-ready documentation and a per-project integrity assessment, built to follow the ICVCM Core Carbon Principles, SBTi requirements and the incoming EmpCo Directive.
Meet the standard behind every credit we sell.
We analyze 600+ data points per project, scored before it is offered and rescored as new data comes in.
We confirm a project's registry, methodology, location, and foundational documentation. Any red flags here end the conversation before it starts — ensuring only legitimate projects enter our pipeline.
We dig into additionality: What would have happened if the project didn't take place? Our AI models cross-reference historical data and geospatial imagery to confirm the project's baseline and measure real gains. We also test for Leakage (shifting emissions elsewhere) and Permanence (the project's ability to withstand disruptions like wildfires or political instability).
True climate solutions do more than cut carbon. We review how the project affects local water sources, soil health, biodiversity, and community livelihoods. If it helps achieve UN Sustainable Development Goals (SDGs), so much the better.
This stage checks whether data collection is transparent, ongoing, and verifiable — often with third-party digital MRV (Measuring, Reporting, and Verification) tools. Regular updates prove the project's impact isn't just a one-time claim.
Even a technically sound project can tarnish your brand if it's accused of wrongdoing. We verify alignment with the ICVCM's Core Carbon Principles, check for compliance with European CSRD mandates and comb through public records and press coverage to catch any potential corruption, compliance violations, or emerging controversies.
We filter out 95% of projects on the market, leaving only the top 5% for your portfolio.
What the rest of the market does instead.

- A complete audit trail for every tonne, from project to retirement
- Retirement certificates on the public registries, in your name
- The full SII score and underlying data for each project
- Ongoing MRV updates as projects report against their targets
- Executive summary and board slides, in non-technical language
