Greenly

I tested Greenly for a 320-employee mid-market manufacturing company producing industrial packaging materials, needing to comply with new EU CSRD (Corporate Sustainability Reporting Directive) reporting requirements taking effect plus voluntary CDP (Carbon Disclosure Project) submission for the upcoming reporting cycle. The sustainability lead plus a CFO-office analyst had been tracking emissions manually in spreadsheets and wanted a structured carbon accounting platform handling Scope 1 plus 2 plus 3 emissions across manufacturing operations plus supply chain plus business travel.

Spend-based carbon accounting was the entry feature. Greenly auto-categorized 18 months of accounting transactions (4200 entries) from QuickBooks Online into emission categories using the EXIOBASE plus DEFRA emission factor database, producing an initial baseline Scope 3 estimate within 72 hours of integration. Activity-based refinement for Scope 1 plus Scope 2 used direct utility plus fuel consumption data from invoices plus meter readings, achieving more accurate emissions vs spend-based proxy. Supplier engagement module let the team send carbon questionnaires to top-20 suppliers (representing 70 percent of supply chain spend) tracking response rate plus emissions data quality scoring, vs the prior manual email outreach that hit 30 percent response. CSRD-aligned reporting templates plus CDP submission export formats covered the 1200 disclosure data points required, eliminating the manual mapping work the team had been planning for Q3. Industry benchmark comparisons against 80-plus peer manufacturing companies showed the company emission intensity per revenue dollar at 18 percent below industry median, a finding the marketing team used in customer sustainability conversations.

Setup complexity was the friction point. Initial onboarding required 24 hours of sustainability-lead time across 4 weeks to upload utility bills plus supplier lists plus fleet vehicle records plus business travel logs, slower than the marketing claim of 2-week onboarding. Emission factor accuracy varied by category - manufacturing-specific factors (steel, plastics, energy) were well-validated against scientific literature but office-services factors (cloud computing emissions, office cleaning services) lagged with broader ranges that the sustainability lead flagged as needing assumption documentation in disclosure. The CSRD reporting depth covered the EFRAG ESRS standards (E1 climate, E2 pollution, E3 water, etc.) but the materiality assessment workflow required workshop facilitation that Greenly provided as paid consulting add-on at 8000 EUR per engagement. Pricing at 12000 EUR per year for the 320-employee tier was higher than the Persefoni starter plan at 8000 USD but lower than Watershed Enterprise at 25000 USD-plus. Audit trail for third-party assurance by KPMG plus PWC plus Deloitte was clean but required manual export to PDF for auditor handoff.

Verdict: pick Greenly when the company is 50-1000 employees, EU-headquartered or EU-exposed for CSRD, budget per year is 8000-15000 EUR, and spend-based plus activity-based carbon accounting both matter for accuracy improvement over time. Pick Persefoni when North America-headquartered plus 100-500 employee SMB plus public-company reporting (SEC climate disclosure) drives the use case. Pick Watershed when 1000-plus employees plus enterprise sophistication plus integration depth (Salesforce, NetSuite, SAP) matters at 25000-plus USD annual budget. Pick Sweep when product-level carbon footprint per SKU matters for retail plus consumer goods. Plan A for compliance-first SBTi (Science Based Targets) alignment with strict scientific methodology.
