We believe carbon accounting shouldn't break the bank. Greenly provides enterprise-grade features with a streamlined cost structure, allowing you to reallocate your budget toward actual decarbonisation actions.
Watershed’s model relies on professional services, while Greenly’s AI handles the heavy lifting. This tech-led approach ensures high accuracy and faster results without the premium price of a consultant-heavy solution.
Unlike US-focused legacy players, Greenly offers a truly global database. We empower companies to navigate the world’s strictest regulations with ease. Our platform features a specialized US database and is trusted by over 200 US companies, making us the preferred choice for organizations with complex, international footprints.
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.
Complexity is the enemy of speed. Greenly provides a user-friendly experience that simplifies data collection for your entire team, removing the friction that typically slows down reporting cycles.
Stop juggling disconnected tools. Greenly is the only platform that unifies GHG accounting, LCAs, and ESG reporting (CSRD/IFRS) into a single, streamlined workflow - giving you total transparency without the operational overhead.
