Interested in joining?

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

Climate Action 100+ is an initiative that facilitates engagement between institutional investors and the companies in which they invest. It has grown rapidly since its 2017 inception. As a result, many of the engagements with focus companies are at capacity, particularly in Europe. Engagement teams are limited in size to ensure effectiveness. For this reason, it may not be possible to accommodate all prospective signatories.

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—available only to asset owners.)


Please complete the following form to register your interest. A network representative will respond regarding options to get involved. 

  • Participants engage with focus companies directly. Asset managers and engagement service providers are required to join as participants. Supporters are asset owners who publicly support Climate Action 100+ as well as its goals and objectives, but do not participate directly in engagements with focus companies.
  • One of the investor network coordinators will get in touch to review whether the engagements you select remain open to new signatories. Given the unprecedented level of support and participation from investors in Climate Action 100+, new signatories may be asked to consider joining engagement groups that are relatively less well-resourced, where possible and appropriate.

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