Senken

Carbon credits are no longer marketing claims, they're legal statements challenged by auditors, boards, and journalists. In an era where a single greenwashing accusation can cost millions and destroy reputations, sustainability leaders need more than credits. They need a defensible case. 

Senken is the partner for audit-ready carbon procurement. We equip sustainability leaders with high-integrity carbon portfolios where every credit is backed by scientific and legal proof — not vague assurances, but evidence that withstands C-suite questions and regulatory review. 

Unlike legacy brokers who push inventory from their own balance sheets, Senken operates as a structurally independent platform. We curate based solely on data merit. Through our proprietary Sustainability Integrity Index (SII), we vet every credit against 600+ data points and reject 95% of market projects. Only top-tier credits, aligned with Oxford Principles and CCP-approved methodologies, reach your portfolio. 

But rigorous selection is only half the story. Senken delivers a Champion's Kit: executive summaries, project vetting reports, and compliance documentation, everything sustainability managers need to answer any question before it's asked. Whether facing internal auditors, the board, or external regulators, you'll have the evidence ready. 

Our approach has resulted in zero audit challenges across our customer base. Companies like Deutsche Telekom, Lufthansa, DZ Bank, Vodafone, and R+V partner with Senken to protect their climate strategy and reputation. 

For sustainability leaders navigating CSRD reporting deadlines, year-end audits, and growing regulatory pressure, Senken provides the confidence to lead. We don't just sell credits, we build defensible climate strategies that survive audits, boards, and headlines.
