Quick Summary

Making Carbon Accounting Accessible

The enterprise carbon accounting market — Sweep, Persefoni, Watershed — serves organizations that have already made sustainability a strategic function with dedicated teams and budgets. But the majority of companies required to report under CSRD are not in that category. They are mid-market organizations with one or two sustainability professionals, limited internal data infrastructure, and a compliance deadline that is now real.

Greenly was built for that majority.

Founded in Paris in 2019 and now serving over 2,500 clients across Europe, the United States, and the United Kingdom, Greenly has positioned itself as the most accessible serious carbon accounting platform on the market. It is not a spreadsheet replacement or a simple carbon calculator — it covers all three GHG Protocol scopes, supports CSRD and SBTi alignment, includes product-level Life Cycle Assessments, and integrates with over 100 enterprise systems. But it does all of this through AI guidance and tiered onboarding that significantly reduces the technical burden on small sustainability teams.

The result: Greenly is ranked #1 in Sustainability Management software on G2, reflecting strong user satisfaction among the SME and mid-market segment that represents its primary audience.

EcoPilot — AI That Guides, Not Just Automates

Most AI features in ESG software are invisible — anomaly detection running in the background, automated factor mapping happening without user interaction. Greenly’s EcoPilot is different. It is a conversational AI copilot embedded throughout the platform that actively guides users through carbon accounting, CSRD compliance, and decarbonization strategy.

For sustainability teams without deep technical carbon expertise — which describes most SME and mid-market teams — EcoPilot reduces the learning curve that typically makes carbon accounting feel inaccessible. Rather than navigating a complex system of emission factors, calculation methodologies, and framework requirements independently, users can ask EcoPilot questions and receive guidance tailored to their specific situation.

This AI-native approach is what distinguishes Greenly from platforms like Plan A or Normative in the accessible mid-market segment — and it is directly reflected in the platform’s #1 G2 ranking, where ease of use and intuitive design are the most frequently cited strengths.

Key Capabilities

Scope 1, 2, and 3 carbon accounting. Greenly covers all three scopes using both spend-based and activity-based methodologies. The platform defaults to spend-based approaches for rapid initial assessment — connecting to financial systems and calculating emissions based on expenditure data — with activity-based options for organizations requiring greater granularity, particularly for Scope 3 hotspot identification.

CSRD module — 1,000 hours to under 100. Greenly’s CSRD feature streamlines compliance with European disclosure requirements, supporting automated data collection, double materiality assessments, XBRL tagging, and xHTML exports. The platform includes expert guidance and claims to reduce reporting time from 1,000 down to under 100 hours — a meaningful reduction for teams managing CSRD alongside other responsibilities.

Product carbon footprints (LCA). Beyond organizational reporting, Greenly includes Life Cycle Assessment tools for product-level emissions analysis — enabling companies with both internal and product-level sustainability requirements to manage both within the same platform. This is a differentiator in the mid-market segment where product carbon footprints are increasingly required by customers and regulators.

EcoVadis preparation. The platform makes it easy to participate in EcoVadis assessments by streamlining data collection and reporting — gathering sustainability data from suppliers and internal teams, organizing it centrally, and enabling direct EcoVadis submission. For companies that need both their own carbon footprint and their EcoVadis scorecard, this integration reduces duplication.

100+ enterprise integrations. Greenly integrates with financial systems, ERPs, energy platforms, and operational data sources via API — enabling both spend-based and activity-based data collection without manual extraction. Real-time emissions tracking based on actual expenditure data is a consistently praised feature among users.

Employee engagement. The platform includes tools for raising employee awareness — sustainability challenges, training content, and engagement features that make sustainability visible beyond the sustainability team. For SMEs where building internal culture is as important as compliance, this is a practical differentiator.

Pricing

Greenly offers tiered pricing plans. Standard plans are available for SMEs, with enterprise options for larger organizations. Pricing is not publicly listed in full — multiple users flag that pricing details can be unclear, making budget assessment challenging without direct engagement.

The platform is consistently described as costly for small organizations and small businesses, though the long-term benefits are acknowledged to outweigh the initial investment for those who use it effectively.

What Users Consistently Report

Across 103 verified G2 and Capterra reviews, the pattern is clear on both strengths and weaknesses.

What works well: User-friendly interface. Responsive and knowledgeable support team. Real-time analytics. Effective carbon tracking automation. EcoPilot guidance through complex processes.

What needs improvement: Some users report data inconsistencies — including positive amounts not included in totals, incorrect currency handling, duplicate data, and categories inconsistently assigned emissions. Strong internal verification was necessary, as several mistakes could have slipped into the GHG inventory. This is honest feedback that prospective users should factor into their evaluation — Greenly is a strong starting point, but data quality management requires active involvement from the client team.

The best thing about working with Greenly isn’t in the platform — it is the people. The Greenly team is incredible to work with: responsive, direct, friendly, and available over video chat to dig into the nuances of a company’s operations. This people-first support model is a consistent theme across reviews.

Strengths

• #1 rated Sustainability Management software on G2 — strong peer validation in the SME and mid-market segment
• EcoPilot AI copilot reduces the technical burden on small sustainability teams materially
• CSRD module with XBRL tagging and double materiality assessment — reduces reporting time from 1,000 to under 100 hours (vendor claim)
• Product-level LCA alongside organizational carbon accounting — broader scope than most mid-market alternatives
• EcoVadis preparation integration — valuable for companies managing both their own footprint and supplier ratings
• 100+ enterprise integrations for automated data collection
• Tiered pricing provides a lower entry point than enterprise platforms

Limitations

Data quality requires active client involvement. User reviews flag data inconsistencies in automated calculations — positive amounts missing from totals, duplicate data, currency handling errors. Organizations that require audit-ready outputs for CSRD assurance should plan for significant internal validation alongside Greenly’s outputs.

Less suited for Fortune 500 complexity. Greenly’s strengths — accessibility, AI guidance, tiered pricing — reflect a product designed for SME and mid-market needs. Organizations managing hundreds of entities, complex multi-framework disclosure obligations, or supplier engagement programs at scale will typically outgrow the platform. Sweep or IBM Envizi serve those requirements.

Pricing opacity. Multiple users note that it can be difficult to figure out what features are included at which price point. This creates friction during budget planning.

Scope 3 granularity defaults. The spend-based default for Scope 3 is faster but less granular than activity-based methods for identifying value chain hotspots. Organizations with specific Scope 3 Category 1 requirements should clarify methodology depth during evaluation.

Where It Fits in the Market

Greenly occupies a well-defined and valuable position: the best-rated accessible carbon and ESG platform for organizations that are serious about sustainability but are not yet operating at enterprise scale.

For a company with 200–2,000 employees that needs to measure its carbon footprint, prepare a CSRD disclosure, engage with EcoVadis, and build internal sustainability culture — without a six-month implementation project or a six-figure software budget — Greenly is among the strongest options available in 2026.

For organizations that have outgrown this profile — managing complex supply chains, multiple regulatory frameworks simultaneously, or thousands of suppliers — the step-up platforms are clearly Sweep, Watershed, or Plan A, depending on whether multi-framework ESG breadth, climate program management, or decarbonization strategy is the priority.
