# CalPERS Reaches $71 Billion Climate Investment Milestone Amid Calls for Transparency Sierra Club urges the pension fund to stop financing fossil fuel expansion projects. - **Source:** [CleanTechnica](https://cleantechnica.com) - **Published:** 2026-11-10 - **Topic:** [Finance](https://brifing.si/c/finance) - **Original article:** - **On Brifing:** https://brifing.si/s/ffe91060-3fa9-4f68-a341-815feb425e9b ## Pension Fund Climate Milestone The California Public Employees’ Retirement System, known as CalPERS, reported its climate-focused investments reached $71 billion by June 30, 2026. This figure represents a significant increase from the $59.7 billion recorded one year prior. The fund aims to hit a $100 billion target for climate-related assets by the year 2030. ## Sierra Club Advocacy Efforts The Sierra Club acknowledged the progress made by CalPERS but demanded stricter transparency standards regarding these investments. They argue that the total dollar amount does not clearly indicate how much new capital is actively supporting clean energy projects. The organization continues to push for clearer definitions of what qualifies as a solution. ## Portfolio Risk and Emissions Despite the growth in green investments, CalPERS reported that financed emissions across its analyzed asset classes rose by approximately 6 percent last year. The fund attributes this increase to holding higher-emitting assets that it intends to decarbonize over time. Currently, the implied temperature rise for its public equity holdings is 2.9°C. ## Demands for Policy Reform Sierra Club officials are urging the pension fund to stop financing fossil fuel expansion entirely. They suggest that CalPERS should prioritize projects that require new capital for development rather than existing assets. The group emphasizes that reducing climate risk requires a comprehensive review of the fund's entire global investment portfolio. ## Transparency and Credibility Concerns The Sierra Club has consistently challenged the credibility of CalPERS' climate reporting through board meetings and public op-eds. They previously collaborated with the California Common Good coalition to demand a full list of investments counted toward the $100 billion goal. They seek science-based standards to ensure real-world emissions reductions occur. ## Historical Context of Standards In 2025, the Sierra Club published its Principles for Climate Solutions Investments to guide institutional investors. Their January 2026 Climate Solutions Gap report specifically highlighted CalPERS as a case study for why ambitious targets require rigorous eligibility criteria. These documents serve as the foundation for their ongoing lobbying efforts with the fund. ## Mechanisms of Investment Growth CalPERS clarified that the $11.3 billion increase in climate-related assets resulted from both new capital deployments and market gains on existing holdings. This dual growth path complicates the assessment of how much actual new infrastructure is being built. The fund remains the largest public pension system in the United States today. ## Future Outlook for Pensions The tension between fiduciary duty and climate impact remains a central theme for large institutional investors like CalPERS. As the fund approaches its 2030 target, the pressure to align financial returns with environmental goals will likely intensify. Stakeholders will continue monitoring whether the fund adopts more restrictive policies against fossil fuels. ## Sources covering this story - https://cleantechnica.com/2026/11/09/sierra-club-welcomes-calpers-71-billion-climate-solutions-investment-milestone-urges-fund-to-end-financing-of-fossil-fuel-expansion/ — --- _Summary written by Brifing from the original reporting.
