“Partnering with Carlyle AlpInvest will help add the scale and execution expertise needed to advance our investment objectives,” said Nick Abel, Portfolio Manager of CalSTRS Sustainable Investment and Stewardship Strategies. “This collaboration aligns with our long-term outlook and mission to provide a secure retirement for California’s public educators and their beneficiaries. The collaboration enhances the way we access opportunities to further position CalSTRS as a global partner of choice and supports our commitment to delivering financial results alongside positive sustainability outcomes.” 

The initiative will seek to identify climate-related opportunities that demonstrate positive sustainability outcomes across a range of themes. The approach is rooted in a flexible, intent-based framework designed to reflect a wide spectrum of global opportunities.
