Climate groups are challenging South Korea's National Pension Service (NPS), one of the world's largest retirement funds, to disclose discussions regarding limitations on coal investments. Three activist groups have jointly filed a case at the Seoul Administrative Court, accusing the welfare ministry, which oversees the fund, of withholding minutes of meetings where coal divestment policies were discussed. According to the campaigners, NPS is legally required to share details or documents related to management committee meetings, with the option to withhold minutes for up to four years if their publication is deemed to potentially impact the fund's performance or market stability. NPS, with assets worth approximately $751 billion, had been expected to provide details on reducing holdings in coal-related companies after pledging to adopt investment-restriction strategies in 2021. The fund currently holds stakes in companies such as Korea Electric Power Corp. and Posco Holdings Inc. Despite global pension funds aiming to align their portfolios with climate targets, the task has been complicated by the underperformance of environmental, social, and governance (ESG) funds, as well as increased profits for fossil fuel producers due to fuel supply disruptions caused by Russia's invasion of Ukraine. South Korea's government, led by President Yoon Suk Yeol, has also lowered short-term targets for renewable energy additions and eased emission reduction burdens on major polluters. NPS declined to comment on the case.
