How this list was built

The recorded descriptions help you assess these company matches. Check a company’s website for its current services and locations.

What qualifies
Company records associated with Barcelona, Spain whose business descriptions match “green building energy consultants” by meaning at the Exact setting.

Match quality
RevenueBase's August 25, 2026 study assessed 4,198 description/company pairs across matching settings. The publisher reports 86% good or better at Exact. This evaluates the method across queries; it does not audit this individual list. Recorded company descriptions, where available, help you judge each match yourself. Read the full methodology: how the lists are built and what the study measures.
