Allocators write their own climate rules as regulators retreat

La Caisse anchored $164 billion, just under a third of its assets, to staying the course—a public commitment that North American headwinds have made scarce and that the pension wrote without asking anyone's permission. No rule in Ottawa or Quebec City requires a Canadian pension to define a climate allocation, set transition metrics, and hold itself to them. The board and investment committee decided on their own that the institution should be measured against a standard of its own making, and the amount is the figure attached to that commitment.

BlackRock's €70 billion mandate from bpfBouw is the same phenomenon in a different key. The asset manager won the fiduciary assignment by promising ESG data and analysis—reporting capability rather than stewardship posturing or new exclusion screens. The mandate defines ESG alignment as the ability to measure and disclose, a different contract from the one shareholder-proposal fights assumed.

The two announcements land as the formal rulebook is being pulled apart. The SEC has proposed rescinding Rule 14a-8, the 1942 mechanism that puts climate and pay resolutions on US ballots, and the EU is narrowing CSRD, stripping double materiality from its mandated filing without a deadline. The proposals still leave the proxy plumbing intact and require disclosure from thousands of companies, but they abandon the idea that public regulators would set one common standard for what counts as climate-aligned capital. If a definition emerges now, it will be made inside the allocation committee.

The largest money is already choosing to write its own standards. New York City's comptroller has put a $5 billion climate pitch before three separate fiduciary boards—BERS, TRS, and NYCERS—and the number becomes an allocation only after each board prices it separately. That makes it a self-defined climate mandate: three fiduciary reviews will decide what the city can underwrite, with no single compliance department to settle the question.

The comptroller's number matters less as a target than as a procedure. The three boards will each decide, from their own fiduciary duties, whether to anchor a pipeline that the comptroller says federal inaction has starved; no regulatory taxonomy is on the table. That question will be answered three times, possibly three different ways, and that dispersion is the price of self-definition.

Schroders is building a similar bespoke instrument for adaptation. Its work with CalPERS rates 95 of 102 cost-benefit cases as investable, and the real contribution is the screen itself: a framework that says what adaptation looks like for a public pension, built by the institution that will be judged by it.

In the day's charity mandates, selling a fossil-fuel holding changes who owns it, not the emissions it produces. The effect test, rather than the label, is what matters, and it only bites at scale. A foundation that sells an oil-weighted equity stake has not removed a tonne of carbon from the atmosphere; it has moved the claim on that tonne to someone else's balance sheet. If the buyer has no stewardship program, the sale may even increase emissions over time.

If stewardship only bites at scale, then a mandate must define what scale means, who reports on it, and what happens when the reporting shows nothing; those are contract terms rather than compliance checkboxes. BlackRock's bpfBouw win suggests those terms are now being priced: the mandate went to the manager that could supply the reporting infrastructure, ahead of any particular voting record.

The danger in this shift is fragmentation. When La Caisse defines its climate allocation one way, New York's three boards define theirs three ways, and bpfBouw contracts for a particular reporting capability, there is no common yardstick for the capital market as a whole. Managers will have to run multiple reporting systems, and small allocators will find the bespoke standards of large pensions expensive to replicate. That cost, rather than any reason to mourn a centralized rulebook, is what the current direction imposes.

The asset management industry will adapt, because it must. BlackRock's win shows that ESG capability is now a commercial requirement for large fiduciary mandates, a condition of the bid rather than a public-relations add-on. Every manager that wants a €70 billion Dutch pension book has to build the data plumbing first; that may be a better incentive than any disclosure directive.

The regulators were better at judging disclosure than at judging climate ambition. By stepping back, the SEC and the EU may be surrendering standard-setting to institutions that actually have money at stake. Those institutions are now writing standards that reflect their own investment horizons—La Caisse's allocation and bpfBouw's mandate are both promises measured in decades. The standards will be less uniform, but they will be owned by the people who bear the risk.

The next test is whether the self-defined standards hold under stress. La Caisse has allocated $164 billion to staying the course, but the market has not yet priced whether that course survives a fossil-fuel rally or a green-asset drawdown. BlackRock's reporting-based ESG contract will be tested when the data shows an uncomfortable result. The allocators are writing the rules now; they will also have to live under them, starting with the first data report under bpfBouw's contract and the first drawdown in that book.
