Disclosure is not allocation
A decade of sustainability reporting has produced an enormous quantity of measurement and a much smaller quantity of redirected capital. On the difference, and why it matters.
The theory of change underlying mandatory sustainability disclosure is straightforward and largely unexamined. Firms disclose. Investors observe. Capital reallocates. Emissions fall.
The first link is well documented. Disclosure regimes produce disclosure, in volume, rapidly. The second is plausible. The third is where the evidence becomes uncomfortable.
What the data show. Studies exploiting the staggered introduction of disclosure requirements across jurisdictions consistently find large changes in what firms report and small changes in how capital is allocated. The effect is not zero. It is concentrated — and this is the finding that matters — among firms facing binding external financing constraints, where cost-of-capital effects are both statistically and economically material.
For firms with ample internal cash flow or established banking relationships, the measured effect on financing terms has been close to indistinguishable from noise. Which is to say: the mechanism operates through the credit channel, and the credit channel only bites where credit is scarce.
Why the interview evidence matters. Quantitative work on this question is necessarily indirect, because allocation decisions are made inside institutions and observed only in their aggregate consequences. Interview evidence from allocation decision-makers has been consistently illuminating and consistently deflating: internal sustainability mandates, in a substantial number of institutions, are not translated into position-level constraints. They exist at the level of policy documents and reporting frameworks. The portfolio manager is not, in practice, prevented from taking a position.
This is not hypocrisy so much as institutional gap. The mandate is genuine; the mechanism for making it bind was never built.
The implication for policy. If disclosure operates principally through the credit channel, then the design question is not how to improve reporting quality in general but where financing constraints are tight enough for information to move price. That is a considerably narrower and more tractable question than the one most standard-setting discussions have been addressing, and it points toward instruments — lending standards, capital requirements — that sit outside the disclosure framework altogether.
