Climate Action 100+ (CA100+) is an investor-led initiative to ensure the world’s largest corporate greenhouse gas emitters take appropriate action on climate change in order to mitigate financial risk and to maximise the long-term value of assets.

As of 2025, the initiative has more than 600 investor signatories and focuses on engagement with more than 160 focus companies across the globe.

Launched at the end of 2017, CA100+ has since become the largest global investor engagement initiative on climate change.

The work of the initiative is coordinated by five investor networks: Asia Investor Group of Climate Change (AIGCC); Ceres; Investor Group on Climate Change (IGCC); Institutional Investors Group on Climate Change (IIGCC); and Principles for Responsible Investment (PRI). It is supported by a global Steering Committee.

As per the goals of Climate Action 100+, investors seek to ask companies to:

  • Implement a strong governance framework which clearly articulates the board’s accountability and oversight of climate change risk.
  • Provide enhanced corporate disclosure and implement transition plans to deliver on robust targets. This should be in line with the final recommendations of the Task Force on Climate-related Financial Disclosures (TCFD) and other relevant sector and regional guidance, to enable investors to assess the robustness of companies’ business plans and improve investment decision-making.
  • Take action to reduce greenhouse gas emissions across their value chain, including engagement with stakeholders such as policymakers and other actors to address the sectoral barriers to transition. This should be consistent with the Paris Agreement’s goal of limiting global average temperature increase to well below 2 degrees above pre-industrial levels, aiming for 1.5 degrees. Notably, this implies the need to move towards net-zero emissions by 2050 are sooner.

Engagement with companies are coordinated via five regional working groups, reporting to the global initiative on a periodic basis:

  • AIGCC-PRI Asia Engagement Group – 33 companies
  • Ceres North America Engagement Group – 33 companies
  • IGCC Australasia Engagement Group – 15 companies
  • IIGCC European Engagement Group – 46 companies
  • PRI Global Engagement Group – 42 companies

In addition the coordinating investor-company engagement, CA100+ undertakes the following global strategic projects:

  • Net-Zero Company Benchmark – helps investor signatories to evaluate company ambition in tackling climate change and inform engagement priorities.
  • Sectoral Engagements - supports sector engagements with a broad set of stakeholders to enable companies to set and deliver on ambitious targets through the removal of sectoral ecosystem barriers.
  • Thematic Engagements - supports a range of thematic engagements to encourage enhanced performance from companies on a defined theme, for example an indicator under the Net Zero Company Benchmark, or a topic such as State-Owned Enterprises.
