What Carbon Tool does

CarbonTool is a SaaS carbon accounting and sustainability platform developed by the BuildGreen team in Bucharest, Romania, which has delivered 500+ BREEAM, LEED, and EDGE building certifications since 2010. The platform measures, reports, and reduces Scope 1, 2, and 3 emissions on a GHG Protocol-aligned foundation, and produces reports for CSRD, VSME, GRI, CDP, ISSB, SBTi, TCFD, and PCAF from a single data backbone. Its primary commercial customers are enterprise real estate owners, manufacturers, financial institutions, healthcare operators, logistics providers, and SMEs across Europe, with Real Estate & Construction listed as the principal vertical.

The product is built around three integrated modules: Carbon Accounting (Scope 1, 2, 3 measurement with 200+ pre-built emission source templates and AI Upload for extracting data from invoices and bills), Reporting (CSRD, VSME, GRI, CDP, ISSB from the same data structure with audit-ready trails), and Decarbonisation (scenario modelling, CAPEX estimates, SBTi/CRREM targets, and an initiative library). Pathfinder AI guides users through setup decisions, multi-entity consolidation supports group-level reporting, and API/MCP connectivity enables integration with ERP, BI, and data warehouse systems. The company is independently owned and bootstrapped, with no venture capital and no acquisition roadmap.
