Take control of your Scope 3 carbon exposure.
Scope 3 emissions represent up to 90% of an enterprise's total carbon footprint, and are now subject to mandatory disclosure under CSRD and supply chain due diligence obligations. Survey-based supplier portals consistently fail because suppliers don't engage with them. Cozero takes a different approach: structured supplier data sharing through the Cozero platform, combined with customer success engineering to build programs that actually work, calibrated to your supply chain reality, not a templated workflow.

Scope 3 is where your largest carbon risk lives, and where CSRD and LkSG require action.
The regulatory reality
Under CSRD, Scope 3 disclosure is mandatory for companies in scope. Under LkSG, supply chain due diligence covers human rights and specific environmental obligations, and the trajectory across EU and German legislation is toward broader carbon-related scope. Scope 3 is no longer optional, and estimating it from industry averages is no longer sufficient for audit or investor scrutiny.
The commercial risk
Suppliers with no carbon data are a liability in customer tenders, ESG ratings, and CSRD audits. Procurement teams increasingly face supplier carbon clauses. Without primary data, your Scope 3 figures are estimates, and estimates do not hold up under regulatory or commercial scrutiny.
The management layer
Cozero provides the platform and the program expertise to collect primary supplier data at scale, through the Cozero PCF module, supported by customer success engineering. Scope 3 data structured with GHG Protocol methodology and the traceability that CSRD, LkSG, and procurement audits require.
