The CO2 questionnaire problem
Every week, SMBs across Europe receive sustainability questionnaires from large corporate customers. The questionnaires ask for Scope 1, 2 & 3 data, GHG Protocol methodology, and a verified report they can pass to their own auditors.
The existing tools were either built for multinationals with dedicated ESG teams, or required a consultant costing tens of thousands of euros. Small businesses had no practical path.
We built co2.expert to give any business — from a 10-person logistics company to a regional manufacturer — the ability to measure, report, and share a complete carbon footprint in days, not months.

What we stand for
Three principles guide every decision we make.
Transparency
Every emission figure is traceable to a specific data input and calculation. We publish our methodology openly so anyone can verify our numbers.
Science-based
Our measurement framework follows GHG Protocol and ISO 14064. We stay aligned with IPCC guidance and CSRD requirements.
Built for business
We designed for SMBs with real deadlines, not for multinationals with ESG teams. Fast to set up, easy to maintain, and ready to share with your customers.
What we build
co2.expert is a carbon footprint measurement platform for small and medium businesses. It covers Scope 1, 2 & 3 emissions, follows GHG Protocol methodology, and produces a verified, customer-ready PDF report your team can actually share.
It is designed for companies that receive sustainability questionnaires from large customers — manufacturers, logistics providers, food producers, professional services firms — and need to respond quickly without hiring a consultant or building an ESG team from scratch.
