Cozero

Cozero is a Berlin climate software company founded in 2020, registered as Cozero GmbH at Amtsgericht Berlin-Charlottenburg under HRB 218586 B.

It pitches a shift from carbon accounting to carbon controlling: data collection by bulk upload, API or direct supplier input, a calculation engine with more than one million vetted emission factors, and dashboards designed so finance and sustainability teams work from the same data. Beyond the accounting layer, Cozero offers target setting, forecast building with carbon price scenarios and an evaluation of reduction actions by ROI, payback period and marginal abatement cost.

Reporting covers CSRD, CDP and internal governance with audit management and read-only access for auditors. Separate solution pages cover corporate and product carbon footprints, supplier engagement and CBAM.

Be precise about the CSRD claim: the vendor’s own CSRD page scopes it to ESRS E1 climate data, not the full set of ESRS standards. Hosting is stated as an AWS cloud environment without a named region. Pricing is not published and goes through a demo request. It sits well for an enterprise with an emissions focus, less so for a full sustainability statement.

What Cozero does well

• Carbon controlling approach with forecasting, carbon price scenarios and ROI-ranked actions
• Over one million vetted emission factors and custom factor support
• Supplier engagement for Scope 3 and PCF solutions
• Audit management with read-only access and an immutable audit trail

Where Cozero falls short

• CSRD coverage is scoped to ESRS E1 climate data on the vendor’s own page
• Hosted on AWS with no region named on the security page
• No published pricing; demo request only
• No Cozero-specific certification stated; only its cloud providers’ attestations are listed

Standout feature. Carbon treated as a financial variable: forecasts, carbon prices and ROI-ranked reduction actions inside the same platform that produces the disclosure data.
