How we ranked them

What counts

Official roles published by summit organizers since 2020: B20 task force chairs and co-chairs, COP principal, strategic and industry partners, and APEC host committee members and sponsors.

How the order is set

Companies are ranked by the number of summits they have backed, then by how many different forums, then by the seniority of their roles (chair before co-chair before partner), then by the most recent summit. Companies with equal scores share a rank (shown with =). Where a tie crosses the 100 mark, tied companies are listed alphabetically.

G7 and W20

The G7 and the W20 rarely publish corporate partner lists, so few companies appear for them yet. We will add them as rosters are published.

Is your company missing?

If your company has held an official role at a G7, G20, B20, W20, COP or APEC summit, tell us and we will review it for the next update.
