Interested in joining?

If you are an institutional investor (investment manager, asset owner, or engagement service provider) please use the form below to express your interest in joining Climate Action 100+. Applications are subject to engagement availability.

Climate Action 100+ has grown rapidly since its 2017 inception. As a result of the unprecedented level of support and participation from investors in Climate Action 100+, many of the engagements with focus companies are at capacity, particularly in Europe.

Given that engagement teams are limited in size to ensure effectiveness, it may not be possible to accommodate all prospective signatories. We will periodically review company engagement availability and notify prospective investor participants when suitable openings arise.

To join, you must be:

  • An asset owner, an asset manager, or a service provider that is formally representing assets and that typically conducts engagements with companies.
  • A member of one of the coordinating investor networks: AIGCC, Ceres, IGCC, IIGCC, or PRI
  • Able to participate in engagements with focus companies (unless you join as a
    supporter — note that this option is only available only to asset owners.)


Complete the form below to express your interest. A network representative will respond regarding options to get involved.

If you have questions about the sign-on process or about joining one of the five investor networks that support Climate Action 100+, please contact [email protected].
