We're mobilising $10B towards climate projects.

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 through three core pillars: (1) Quality assessment through our proprietary Sustainability Integrity Index (SII) — we assess every project on 600+ datapoints and select only the top 5% of all available projects on the market; (2) An end-to-end platform that supports clients from strategy planning to reporting and communication, with CSRD-compliant documentation and full traceability for auditors and the public; (3) Buyer Protection — if any project in a 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 — more than 84% of carbon credits in registries are low quality according to a Max Planck Institute study. That’s why every project passes through multiple layers of verification: Senken’s proprietary 600-data-point Sustainability Integrity Index, independent third-party ratings from BeZero, Sylvera and others, Oxford Offsetting Principles alignment, and CSRD and SBTi compliance requirements.

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 and 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. For larger programs (neutralising more than 1,000 tCO2 per year), budgets typically start around €100,000, depending on emissions and strategy.

Yes. Senken works with companies of all sizes, from SMEs to corporations like Vodafone and Deutsche Telekom. For smaller businesses or those getting started, Senken Checkout offers a streamlined self-service option to purchase pre-vetted, high-quality carbon credits instantly. 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. Senken Checkout (self-service) lets you purchase pre-vetted, high-quality carbon credits instantly — ideal for companies getting started or needing quick procurement. The Full-Service Platform follows a 5-step process: (1) strategy consultation and portfolio design based on Oxford Principles, (2) procurement of high-quality credits verified by our 600-datapoint SII, (3) transaction and retirement with full traceability, (4) CSRD-compliant reporting with audit trail, and (5) communications support, with a dedicated portfolio manager throughout.

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.

With Senken Checkout, you can complete an instant purchase of pre-vetted credits in minutes. With the Full-Service Platform, once requirements are clarified upfront, we can typically deliver a customised portfolio within 1–2 weeks. Our AI-supported 600+ data point due diligence and single-platform approach 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, human-verified due diligence process filters out the questionable credits on the market and ensures only the highest-quality credits with verified impact reach our clients.
