Where Noissime goes further
Four areas where capabilities diverge at the same price.
Full Scope 3 vs limited coverage
Noissime covers all 15 Scope 3 categories from day one, including purchased goods, business travel, employee commuting, and end-of-life treatment. Greenly's Scope 3 support is limited and often relies on spend-based estimates only.
Document intelligence
Upload utility bills, fuel receipts, and invoices — Noissime's AI extracts quantities, fuel types, and dates, then calculates emissions automatically. Greenly has no equivalent feature, requiring manual data entry for all records.
Supplier automation
Automated outreach campaigns, magic-link portals for suppliers to submit data directly, and AI extraction from supplier responses. Greenly lacks supplier engagement tools entirely, leaving you to chase data manually.
UK compliance built in
SECR and ESOS reporting alongside CSRD, with UK-specific emission factors and regulatory templates. Greenly focuses on French and EU frameworks — UK support is absent, making compliance harder for British businesses.
Similar cost, different value
What you get at each price point.
Noissime
- Free tier available
- Professional from £299/mo (early bird, normally £599)
- Full Scope 3 + supplier tools
- Document intelligence included
Greenly
- No free tier
- Similar price range
- Limited Scope 3
- No document or supplier tools
More capability, same budget
Three reasons SMEs choose Noissime over Greenly.
Same price, more features
At similar pricing, Noissime includes full Scope 3, document intelligence, and supplier automation that Greenly charges extra for or doesn't offer at all.
Ready for UK compliance
If you report under SECR or ESOS, Greenly can't help. Noissime has these frameworks built in alongside CSRD, with UK-specific emission factors and templates.
AI that does the work
From natural language input to document extraction to supplier data processing — Noissime's AI automates what Greenly requires manually, saving hours every week.
Automated supplier outreach that Greenly cannot match
Scope 3 emissions typically represent the largest portion of an organisation's carbon footprint, yet Greenly offers no supplier engagement tools at all. In this Noissime vs Greenly comparison, the automated supplier outreach funnel is the single biggest capability gap.
As the closest SME competitor, Greenly matches Noissime on price but falls short on Scope 3 supplier data collection. With Greenly, you are left to chase supplier emissions data manually through spreadsheets and emails. As a Greenly alternative, Noissime automates the entire process: import your supplier list and the carbon management platform runs an automated outreach funnel. Each supplier receives a free Noissime account showing only the data fields relevant to their category — not a generic form or a confusing enterprise questionnaire. Supplier data flows directly into your Scope 3 carbon accounting without re-entry. In this Noissime vs Greenly comparison, the free supplier accounts and automated data pipeline represent capabilities that Greenly simply does not offer. For SMEs that need credible Scope 3 data, this makes Noissime the clear Greenly alternative.
Free supplier accounts
Every supplier gets a tailored, free account. No sign-up costs, no overwhelming questionnaires — just the relevant data fields for their category.
No manual data chasing
Automated reminders and a direct data pipeline eliminate the spreadsheet round-trips that Greenly forces you to manage manually.
Free carbon reduction plans — a Greenly alternative advantage
Greenly offers basic action plans, but detailed AI-generated carbon reduction plans prioritised by impact and cost-effectiveness are unique to Noissime in this Noissime vs Greenly price bracket.
Every paid Noissime account includes free carbon reduction plans generated by AI. These plans go beyond generic suggestions: they analyse your specific emissions data across Scope 1, 2, and 3, then recommend actions ranked by tCO2e savings potential and scored by cost-effectiveness. As a Greenly alternative, Noissime provides this level of reduction intelligence without charging extra for advisory or consulting. Greenly's action plans are basic and lack the AI-driven prioritisation that makes Noissime's approach actionable. For SMEs comparing Noissime vs Greenly at similar price points, the included free carbon reduction plans represent a substantial additional value that no other carbon accounting software in this bracket delivers.
Impact-ranked actions
AI prioritises every recommendation by potential carbon savings, so your team tackles the highest-impact changes first within budget.
Beyond basic suggestions
Where Greenly offers generic action lists, Noissime delivers personalised, data-driven reduction plans that evolve with your emissions profile.
