6 reasons companies choose Greenly
over Sami
Better platform capabilities
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.
Advanced Climate AI with EcoPilot
EcoPilot automatically categorises complex accounting and logistics data, eliminating the manual work that slows teams down and making your reporting 10x more efficient.
Ease of use
Greenly’s interface is designed for organisation-wide adoption, ensuring that Finance, Procurement, and HR teams can contribute without needing a PhD in carbon accounting.
High-Precision Emission Factors
Decarbonising 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.
True Product Granularity
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.
Proven Scale & Global Ecosystem
With 3,500+ 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.

Pros & Cons
From real user reviews on G2.
- Automation vs. Manual Consulting: Sami often relies on manual data entry and expensive consulting hours to fill the gaps. Greenly’s EcoPilot AI automates up to 90% of data processing, delivering audit-ready ESG reports 10x faster with live "What-If" scenario modeling.
- Complete ESG Platform vs. Basic Carbon Tools: Sami is primarily a carbon calculator. Greenly is a comprehensive ESG platform that goes beyond corporate footprints by integrating Product LCAs and automated CSRD compliance to drive real eco-design.
- Global Reach vs. Local Limits: Sami lacks the infrastructure for global supply chains. Greenly leverages a network of 3,500+ clients across 29 countries, allowing you to instantly collect primary Scope 3 data from suppliers who are already active on the platform.
