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.
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.
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.
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.
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.
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.

Greenly is a complete, all-in-one sustainability suite that covers Carbon, ESG, LCA, and Supplier Engagement. While Sweep focuses on carbon management through its AI agents, Greenly provides a broader range of built-in capabilities - including automated LCA (which Sweep lacks) and faster, more intuitive deployment cycles.
Yes. Greenly is more cost-effective than Sweep’s enterprise-tier plans. We offer transparent, straightforward pricing with fewer additional fees, making high-level sustainability management accessible without the "premium" overhead often associated with Sweep’s model.
Greenly takes AI further. While Sweep’s agents are designed for specific manual interventions, Greenly’s EcoPilot is a unified system that automates your end-to-end compliance. It doesn't just help with tasks; it powers your entire ESG and LCA strategy, delivering deeper insights with significantly less manual oversight.
Expert guidance is part of the package. Every Greenly plan includes a dedicated project manager and ESG experts to guide you through the process. While Sweep often charges extra for flexible support tiers, we provide high-touch, human expertise as standard - so you get the help you need without the hidden fees.
Yes. Both platforms are built to handle the complexity of global organisations.
Yes. Both platforms are built for global complexity, offering multi-country reporting and investor-grade data that meets international assurance standards such as ISAE 3402 and SOC2.
