Key Takeaways
  • • Washington Policy Center opposes Senate Bill 6304, which would require the Washington State Investment Board (WSIB) to apply statutory ESG exclusions to public pension investments, including fossil fuels, prisons, immigration detention, and tobacco.
  • • According to WSIB data cited in the piece, about $7.4 billion is invested in the energy sector, including $5.5 billion in oil and gas, and the bill's coal provision would force divestment from companies deriving 10% or more of revenue from coal.
  • • The author argues the bill's vague "unacceptable greenhouse gas emissions" standard could sweep in far more holdings and that mandated exclusions would reduce investment flexibility at a time when the board must hit a 7.25% assumed return.
  • • The piece cites CalPERS' 2000 tobacco divestment, which it says cost $3.5 billion in foregone returns, as evidence of divestment risk.
  • • SB 6304 is scheduled for a public hearing on Thursday, January 29, in the Senate Committee on Ways & Means at 4:00 PM.
Summary
Washington Policy Center, a think tank, argues that Senate Bill 6304 would convert Washington's public pension investment strategy into a political exercise by mandating a list of environmental, social, and governance (ESG) exclusions. The bill would require the Washington State Investment Board (WSIB) to exclude fossil fuels, prisons, immigration detention, tobacco, and companies meeting vague criteria such as "unacceptable greenhouse gas emissions," and to support shareholder resolutions calling for reduced "violations of responsible investment principles." The article notes WSIB's stated mission to "maximize returns at a prudent level of risk" and says the board evaluates ESG factors only as they affect long-term performance, adding that WSIB has rejected divestment in favor of active ownership.

According to WSIB data cited in the article, roughly $7.4 billion is invested in energy, including $5.5 billion in oil and gas. The coal provision would force divestment from companies deriving 10% or more of revenue from coal, and the author contends the greenhouse gas language could expand that scope considerably.

The article draws on several precedents and data points to argue ESG-linked investing has weakened. It cites CalPERS' 2000 decision to divest from tobacco, which it says cost $3.5 billion in foregone returns, and a Pacific Research Institute study finding a $10,000 ESG portfolio would be 43.9% smaller than an equivalent S&P 500 investment over 10 years. It also reports that sustainability funds saw $13 billion in outflows in 2023 and that the Big Three asset managers sharply reduced support for ESG shareholder proposals in 2024: Vanguard supported none of 400 evaluated environmental and social proposals, BlackRock's support fell from 41% to 4%, and State Street's fell from 43% to 6%. The article also references Larry Fink's 2023 statement that he would no longer use the term ESG.

On Washington's fiscal position, the article notes the legislature raised the pension systems' assumed rate of return to 7.25% in 2025 and deferred payments on Plan 1 unfunded liabilities. The author argues this makes the board's need for investment flexibility greater, not less. The piece is an opinion advocating against the bill, and its claims are presented as the author's position rather than independently verified. SB 6304 is scheduled for a public hearing on January 29 in the Senate Committee on Ways & Means.
