Short answer
Choose Greenly if you need one tool for carbon accounting plus a long list of ESG and regulatory frameworks, especially EU ones such as CSRD and CBAM, or if you need product life cycle assessment.
Choose Ecologi if you want your emissions data to turn into credible climate action. That means expert-led measurement in Ecologi Zero, carbon credits scored through a published assessment framework, multi-year portfolio planning and UK reporting such as SECR and PPN 006, all in one place.
Already using Greenly for measurement? You can add Ecologi for carbon credits and nature restoration without switching tools.

What is the difference between Greenly and Ecologi?
Greenly is built for breadth of reporting. Ecologi is built for depth of climate action. Both measure Scope 1, 2 and 3 emissions and report on them. Greenly takes that data across many ESG frameworks, including EU ones. Ecologi turns it into reduction plans, CPAF-scored carbon credits, nature restoration and a public record of impact.
What is Greenly designed for?
Multi-framework ESG reporting. Named modules for CSRD, CBAM, EUDR, EcoVadis, VSME and more, aimed at businesses with heavy EU reporting obligations.
Product life cycle assessment. ISO-aligned product-level footprints.
Automated data processing. An AI assistant and automated emission-factor matching. Greenly says its database holds more than 500,000 emission factors.
International operations. Offices in Paris, London and New York. After acquiring Normative, Greenly says it serves 4,000 customers in more than 30 countries.
Where does Ecologi have the edge?
Carbon credit due diligence. We score every project ourselves through CPAF on Climate, Nature and People impact, combining BeZero Carbon, Calyx Global, Renoster and Sylvera ratings. Only projects scoring 80/100 or above are eligible.
Multi-year planning. Portfolio Builder models an Oxford Principles-aligned credit plan against your emissions trajectory, shifting towards durable removals as your net zero date approaches.
Public proof. Our Impact Ledger and registry traceability let customers verify claims themselves. On 12 October 2026 it showed 1.22 million tCO2e under management and 95 million trees funded.
PPN 006 built in. Carbon Reduction Plans are part of the platform, not a separate expert engagement.
Expert-led Scope 3. Our team collects supplier data directly rather than relying on spend-based estimates alone.
Is Greenly or Ecologi better for SECR and PPN 006?
Both cover SECR. Greenly's UK pages describe "UK SRS and SECR-ready reports". For PPN 006, which requires suppliers bidding for UK central government contracts above £5 million a year to publish a Carbon Reduction Plan, Greenly lists no named module. Its PPN 06/21 guide says its climate experts help clients create a tailored plan. Ecologi builds Carbon Reduction Plans into the platform, using the same data as your SECR, SBTi and B Corp reporting. If you are bidding, ask both for a sample plan. See our guide to the UK Carbon Reduction Plan.
