We're mobilising $10B towards climate projects.
That starts with making every single credit trustworthy.

Carbon credits are a polarising topic.
We understand why.
Providers push projects from their own balance sheets without telling you. Due diligence is a black box. Prices are opaque. And when something goes wrong, when a journalist calls, or an auditor starts asking questions, the sustainability manager who signed off is the one left standing in the room alone.
What we believe in
Extreme selectivity
Structural independence
Face-to-face partnership
FAQ
Senken is a carbon credit procurement platform that delivers high-quality carbon credits with no greenwashing risk. We help companies implement carbon neutrality strategies from selection to reporting. We analyze every climate project using 600+ data points and select only the top 5% of the market.
Senken differs from other carbon credit providers and platforms through three core pillars:
1. Quality assessment through proprietary Sustainability Integrity Index (SII) - we assess every project based on 600+ datapoints and select only the top 5% of all available projects on the market.
2. End-to-end platform - unlike traditional providers, we support clients from strategy planning to reporting and communication.
4. CSRD-compliant documentation with full traceability for auditors and public,
3. Buyer Protection - if any project in customer's portfolio underdelivers, we replace the credits with a comparable project from our buffer pool.
All Senken credits come from projects certified by top registries including Gold Standard, Verra, and Puro.earth. However, registry certification alone isn't enough - in fact, more than 84% of carbon credits in registries are low quality according to Max Planck Institute study. That's why every project passes through multiple layers of verification:
1. Senken's proprietary 600-data-point Sustainability Integrity Index (SII) due diligence process,
2. Independent third-party ratings from BeZero, Sylvera, and other verification platforms,
3. Oxford Offsetting Principles alignment for client's portfolios,
4. CSRD and SBTi compliance requirements.
We recognize that registry certification is necessary but not sufficient for carbon quality. Our additional screening ensures we find the 5% of credits that deliver real 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 smaller purchases, customers can use self-service Senken Checkout to buy high-quality projects in minutes. For larger programs, we work with companies aiming to neutralise more than 1,000 tCO2 per year. Budgets typically start around €100,000, depending on emissions and strategy. Senken structures cost-effective, compliant portfolios with transparency, traceability, and clear impact.
Yes. Senken works with companies of all sizes, from SMEs to corporations like Vodafone and Deutsche Telekom. For smaller businesses or those getting started with carbon credits, Senken Checkout offers a streamlined self-service option to purchase pre-vetted, high-quality carbon credits instantly - no lengthy procurement process required. For larger organisations or those needing customised portfolios, our end-to-end platform provides full strategy consultation, due diligence, and CSRD-compliant reporting.
CSRD-ready means Senken delivers all documentation and evidence required for the EU Corporate Sustainability Reporting Directive: exportable audit trails, full traceability from purchase to retirement, and structured evidence packs for auditors. This protects against penalties of up to 4% of annual revenue under consumer protection laws.
Senken offers two ways to work with us depending on your needs:
Senken Checkout (Self-Service): Purchase pre-vetted, high-quality carbon credits instantly through our streamlined checkout process - ideal for companies getting started or needing quick procurement.
Full-Service Platform: Our comprehensive 5-step process includes:
1. Strategy consultation and portfolio design based on Oxford Principles,
2. Procurement of high-quality credits, verified by our 600-datapoint Sustainability Integrity Index,
3. Transaction and retirement with full traceability,
4. CSRD-compliant reporting with audit trail,
5. Communications support. Customers get access to a dedicated portfolio manager to track everything on one platform - from discovery to retirement and reporting.
Both options deliver the same quality standards with only the top 5% of credits on the market, with full documentation and traceability.
The availability of high-quality carbon credits is becoming scarcer while regulatory requirements (CSRD, SBTi) are increasing. Companies investing now secure access to the top 5% of projects before everyone rushes to the small supply of quality credits. Speed matters, but never at the expense of quality - with Senken you get both.
Senken works with sustainability leaders including Vodafone, DZ Bank, R+V and Deutsche Telekom, as well as numerous other companies across Germany and Europe. Founded in 2022 in Berlin, we've become a go-to partner for organisations seeking high-quality, audit-ready carbon credits without greenwashing risk.
The timeline depends on your requirements and chosen approach:
Senken Checkout: Instant purchase of pre-vetted credits - complete your procurement in minutes.
Full-Service Platform: With all requirements clarified upfront, we can typically deliver a customized portfolio within 1-2 weeks. For clients needing extensive strategy consultation or complex portfolio design, we can work together over a longer timeframe to ensure the approach fully aligns with your targets and compliance needs.
Our AI-supported 600+ data point due diligence and single-platform approach (from discovery through retirement) significantly accelerates the process compared to traditional multi-vendor procurement, which can take months.
Senken's proprietary Sustainability Integrity Index (SII) evaluates each project across 600+ data points covering: additionality, permanence, leakage prevention, co-benefits, third-party validation from platforms like BeZero and Sylvera, registry status (Gold Standard, Verra, Puro.earth), vintage, geographic risk factors, technology readiness, and financial stability. Only projects passing all criteria make it into our portfolio. This AI-supported, yet human-verified, due diligence process filters out the 85% of questionable credits on the market. Even though projects come from top registries, we recognize that registry certification alone isn't sufficient - our additional SII screening ensures only the highest-quality credits with verified impact are available to our clients.
