6 reasons companies choose Greenly over
Sweep
The All-in-One Sustainability Solution
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.
Industry-Leading Climate AI
Shifting from a service-first to a tech-first approach, Greenly delivers results with precision and speed. Our AI agent, EcoPilot, handles the heavy lifting: it automates complex data ingestion and eliminates guesswork by selecting audit-ready emission factors for you.
Accessible Pricing
Sweep’s premium positioning often comes with significant upfront fees and high entry costs. Greenly offers a value-driven model designed to scale with you, ensuring your budget goes toward actual decarbonisation rather than expensive setup fees.
LCA and PCF Capabilities
Corporate footprinting is only the beginning. To drive real change, you need to look at your products. While Sweep lacks built-in Life Cycle Assessment (LCA) tools, Greenly provides the granular data you need to track and reduce the impact of every product you sell.
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.
Ease of use
While Sweep’s complex configuration often requires a lengthy setup and dedicated internal resources, Greenly is built for speed. We replace months of implementation with an intuitive platform that empowers your team to start reporting in weeks - not months.
