6 reasons companies choose Greenly
over Persefoni
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.
Accessible Pricing
While Persefoni’s high-tier budgets often hide heavy implementation fees and long setup cycles, Greenly offers a transparent, scalable model. By leveraging EcoPilot AI, we reduce deployment costs by up to 80%, ensuring your budget goes toward actual decarbonization rather than software overhead.
Advanced Climate AI
While legacy providers often rely on manual data processing behind the scenes, Greenly’s EcoPilot AI is a true self-service engine. We eliminate the need for slow, manual checks, providing audit-ready results with the precision and speed.
Global Regulatory Expertise
Persefoni is primarily built for US-centric frameworks. Greenly offers a truly global approach, combining the rigor of European CSRD standards with deep expertise in North American regulations like IFRS and TCFD. We ensure your data meets the requirements of every region where you do business.
High-Precision Emission Factors
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.
Smooth Onboarding and Intuitive Design
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.

Pros & Cons
From real user reviews on G2.
- Speed of Implementation: While Persefoni often requires several months for setup and implementation, Greenly enables full, group-wide deployment in just a few weeks.
- Automation vs. Manual Work: Persefoni's premium rates can often include manual data processing. Greenly’s EcoPilot AI automates 90% of the workflow, significantly reducing operational costs while eliminating human error.
- Product-Level Depth: Greenly provides built-in Life Cycle Assessment (LCA) capabilities - a feature Persefoni lacks- to help companies drive actual Scope 3 reductions at the individual product level.
- Global Compliance: Unlike Persefoni’s US-centric model, Greenly supports both CSRD (EU) and SEC (US) frameworks, powered by a massive global database of 300k+ activity factors.
