Carbon Factor Matcher

Intelligent emission factor matching for carbon accounting & LCA

What It Does

Hybrid Search Engine

Combines keyword scoring (0.3) with embedding-based semantic similarity (0.7) for precise factor matching. No manual database browsing needed.

5-Dimension Quality Rating

Each factor rated on technology representativeness, source reliability, geographic fit, time relevance, and factor type — so you pick the best data, not just the first result.

21,000+ Factors

Access the full ecoinvent 3.10 database (Pro) plus 600+ ELCD factors (Free). Covers electricity, fuels, transport, chemicals, metals, construction, and more.
