Carbalytics is a decision-support tool for marketing and acquisition teams. It enables media planners and digital marketing directors to pilot their advertising investments across all major digital channels (Search, Social, Display, YouTube, DOOH) by combining performance indicators (ROAS, CPA, CPM) with estimated carbon emissions per channel, in a single interface. Built on recognized methodologies including GMSF v1.2 (Ad Net Zero), SRI France V2, NégaOctet 2024 and ADEME Base Carbone, Carbalytics produces scenario simulations (growth, cost savings, decarbonization) and generates CSRD-ready exports aligned with GHG Protocol Scope 3 Category 11. Carbalytics is designed for marketing teams that need to go beyond optimization and make strategic trade-offs between performance and environmental impact. All calculations are performed client-side. No data is shared with third parties.
