Climate Action 100+ is an investor initiative to ensure the world’s largest corporate greenhouse gas emitters take necessary action on climate change. More than 320 investors with more than $33 trillion in assets collectively under management are engaging companies on improving governance, curbing emissions and strengthening climate-related financial disclosures. The companies include 100 ‘systemically important emitters’, accounting for two-thirds of annual global industrial emissions, alongside more than 60 others with significant opportunity to drive the clean energy transition.   


Launched in December 2017, Climate Action 100+ is coordinated by five partner organisations: Asia Investor Group on Climate Change (AIGCC); CeresInvestor Group on Climate Change (IGCC); Institutional Investors Group on Climate Change (IIGCC) and Principles for Responsible Investment (PRI). These organisations, along with five investor representatives from AustralianSuper, California Public Employees’ Retirement System (CalPERS), HSBC Global Asset Management, Ircantec and Manulife Asset Management, form the global Steering Committee for the initiative.
