Klimaktiv Ggmbh

What Klimaktiv Ggmbh does

KlimAktiv gGmbH, headquartered in Tübingen, Germany, is a non-profit organization (gemeinnützige GmbH) founded in 2008 that, together with its commercial sister company KlimAktiv Consulting GmbH (founded 2003), develops the CO2-Rechner.PRO SaaS platform and delivers corporate carbon accounting and climate strategy consulting. The dual-entity structure separates the non-profit mission work (public-sector calculators, citizen engagement) from the commercial consulting practice, sharing leadership under founders Stephan Schunkert and Norbert Schmid. The company has operated for over 20 years and reports 11-50 employees across both entities.

The company's core product is CO2-Rechner.PRO, a browser-based carbon footprint calculator that supports Corporate Carbon Footprint (CCF), Product Carbon Footprint (PCF), and full Scope 3 emissions calculation according to GHG Protocol standards. The platform is differentiated by a proprietary database of nearly 2,000 emissions factors (annually updated and GUTcert-certified), trade-corrected electricity factors validated for cross-border flows, and certified methodology supporting CSRD ESRS E1, DNK, and GRI reporting. An integrated Climate Strategy Tool and Plausibilisierung (quality check) service extend the platform into strategy and verification use cases. The product has progressed through five major releases (V5.0 to V5.4) between January 2025 and May 2026.

KlimAktiv generates revenue through three streams: SaaS licensing for CO2-Rechner.PRO delivered in three tiers (Basic, Corporate, Value Chain) on annual subscriptions; professional services including CCF, PCF, CSRD/VSME reporting, climate strategy development, and Future Readiness risk analysis; and customized/white-label CO2 calculators for events, employee engagement, and audiovisual productions. The go-to-market is primarily sales-led for consulting work and product-led for the SaaS tool (with a free demo), supplemented by distribution channels such as ÖKOPROFIT municipal partnerships and a UBA-maintained public calculator. Customers span large enterprises (GLS Bank, DIE ZEIT, Nomad Foods, multiple AOK regional entities, DIEFFENBACHER, WPD, Erwin Hymer) and mid-market firms (RHEINTACHO, Weiling, Arnold Umformtechnik), with several multi-year relationships dating back to 2018-2019.
