How we picked
Every tool here is published on Toolradar with an editorial score of 62 or above, the working bar for this vertical, out of 64 tracked in this category. Ordering follows that score, then third-party review volume, so a tool with one glowing review does not outrank one with a thousand. Scores in specialised business software run lower than in developer tooling, where public review volume is far higher, so this bar is calibrated to the category rather than borrowed from another. The figures update as the catalog does.
FAQ
How many sustainability & esg tools are there?
We track 64 published sustainability & esg tools, of which 63 clear our editorial bar. 64 were added during 2026, which reflects when we indexed them rather than when each vendor launched.
Are there free sustainability & esg tools?
Fewer than you might expect: 6 of 64 offer a free tier, 9%. This is a category where the serious options are paid, and free tiers are trials in practice.
How should I shortlist?
Start from the constraint that will not move: budget, an existing stack you must integrate with, or a compliance requirement. Filter on that first, then compare the two or three that survive. Ranking by feature count leads to the most expensive tool every time.
