Greenly provides a comprehensive ESG platform that scales far beyond basic carbon accounting. While Sami focuses primarily on footprinting, Greenly integrates automated CSRD compliance and built-in Product LCAs - delivering the technical depth required for global organisations.
EcoPilot automatically categorizes complex accounting and logistics data, eliminating the manual work that slows teams down and making your reporting 10x more efficient.
Greenly’s interface is designed for organization-wide adoption, ensuring that Finance, Procurement, and HR teams can contribute without needing a PhD in carbon accounting.
Decarbonizing Scope 3 requires precision. Greenly leverages a library of 300k+ activity-based factors and 25k+ supplier-specific emission factors, providing the localised intelligence needed to engage global supply chains accurately.
Unlike solutions that focus solely on enterprise-level reporting, Greenly offers integrated Life Cycle Assessment (LCA) features. This allows you to measure impact at the product and material level, identifying the hotspots where you can drive the most significant reductions.
With 4,000+ companies already on the platform, many of your suppliers are likely already active on Greenly. This built-in network makes it much simpler to collect high-quality data than starting from scratch with smaller, local tools.
