Greenly alternatives and Greenly carbon accounting compared with a ledger-first option for US companies

Greenly is a real and capable product, and this page says where it wins as well as where it does not fit. Both tools do genuine Scope 1, 2 and 3 carbon accounting. The difference is starting point and buyer. Greenly is questionnaire- and data-collection-first, with deep European regulatory coverage and a factor library it puts at around 300,000 factors. We are ledger-first and US-regulation-first: the inventory is postings built from your AP and utility exports, and the design center is the evidence trail an assurance review samples against.

If you are a European SME doing carbon accounting for the first time, want an established vendor with a broad factor library and a mature CSRD double-materiality workflow, and you value a guided data-collection experience with advisory support, Greenly is a strong pick and probably the more complete product for that job today. It has been built around exactly that user for years. We are not going to claim a European SME is better served by a US-regulation-first tool than by one designed for them.

The fit flips when your trigger is American and your data lives in your ledger. If you are a US company over $1 billion in revenue facing the SB 253 deadline, or a supplier answering a customer's emissions questionnaire, the fastest path to a defensible number is to classify the AP export you already have rather than launch a data-collection project. That is what our carbon accounting software does: AI drafts the scope and category for every line with a confidence level, a human reviews the low-confidence tail, and every figure keeps a link to the invoice behind it. You can watch that happen on your own data in the demo above.

Greenly does not publish standard pricing; like most carbon accounting vendors it quotes based on company size, scope coverage and the modules you need, so the real figure comes from a sales conversation. Anyone printing an exact Greenly price is guessing. We take the opposite approach on transparency: our pricing is published on the pricing page. Compare the wider field on best carbon accounting software, the enterprise-heavy option on the Sweep alternative page, or the accountant-led model on the Sumday alternative page.

Greenly carbon accounting fits a US company that wants a guided first footprint with advisory help and may later need CSRD or product LCAs. It fits less well when the trigger is California SB 253 and the auditor will test US-specific methods. Greenly states it serves 4,000 customers in more than 30 countries, and it has a US site with US pricing pages.

One detail worth asking about in the demo: Greenly's own US pricing FAQ says the accounting export is converted from dollars into CO2 "via the ADEME emissions factors," the French agency's database. That is a sound European method. For a US inventory, most assurance providers expect US-based spend factors, typically EPA's USEEIO supply chain factors, for the spend-based part of Scope 3. Ask which factor set Greenly applies to US spend and whether you can see the factor behind each line. Our spend-based carbon reporting software guide explains why that choice matters.

For a larger enterprise program, compare Persefoni alternatives and Watershed alternatives. For another European platform with a strong CSRD focus, see the Sweep alternative page. For US small and mid-sized companies on a budget, Aclymate alternatives covers a US vendor with published prices, and simple carbon accounting software covers the tools a team without a sustainability function can run itself.
