How this list is ranked

By verified substance, not opinion: published attendance counts, named speaker line-ups, sponsor and exhibitor floors, public discussion, and an organiser-stated audience. The events the catalogue knows most about rank first, which favours the events with real gravity. An event missing from this list may not publish those numbers, and the full Energy & Cleantech listing carries every one we track.
