As the urgency for green transformation grows, the question of whether finance capital can be harnessed to promote green transformation has been raised. Public pension funds are of particular interest since they are publicly governed, have long-term interest, and are growing in proportion to the global investment capital. However, transformative change demands a reprioritization of fundamental values in terms of trade-offs among economic, environmental, and social ends. This article identifies shifts in value judgments in public pension fund investments and particularly focuses on the institutional constraints by which value (re)priorities are resisted by investigating Swedish public pension funds. While there are signs of environmental embedding of the economy, I also note neutralization of the role and investment strategies of the funds, which has a stabilizing rather than a transformative function. The neutralization constrains deep green transformation, which demands politicization of the role of institutional investors.
