• Corporate carbon footprint: GHG Protocol and ISO 14064 accounting with reduction planning.
• Product carbon footprint: ISO 14067 PCFs with a TUV Rheinland-certified method.
• ESG reporting: CSRD/ESRS, VSME, EU Taxonomy and double materiality modules.
• CBAM software: automatic goods classification, emissions by CN code and cost simulation.
• Supplier portal: collects primary emissions data without supplier registration.
• Tanso KI: AI agents for factor mapping, document extraction, questionnaires and report drafting.

A Vietnamese mechanical parts supplier to German machine builders can calculate ISO 14067 product footprints for its customers. A metal products exporter can prepare emissions data per CN code for EU importers under CBAM. A European-owned factory in Vietnam can feed site data into the group's CSRD report.

A TUV Rheinland-certified methodology gives product and corporate footprints credibility with customers and auditors. The CBAM module classifies goods and origin countries automatically from ERP data and simulates cost scenarios when import volumes or countries change. Suppliers can submit primary data through a portal without registering, and one dataset feeds CSRD, CBAM and customer questionnaires.

European industrial buyers increasingly require certified product carbon footprints and CBAM-ready data from their suppliers, including manufacturers in Asia. Vietnamese mechanical, electronics and metal exporters to Germany and the wider EU are among those asked to provide this data.
