CLUSTER CARBON-FOOTPRINT-WEB · 31 ENTRIES · EARLIEST ENTRY 2025-06-18

Carbon footprint calculators

This cluster consists of web-based greenhouse gas and carbon footprint calculators spanning personal, product, transport, and AI/LLM emissions, often with visualization or reporting features. Dated entries appear sporadically from March 2025 to June 2026, with no discernible trend, and most members are undated. Traction is negligible, as the leading activity member (colflux-backend-ia) has zero stars.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
