Financing a Sustainable Future

In this episode, Tom Gosling speaks with Stefano Cascino about how large business groups respond to ESG disclosure rules. When parent companies face mandatory ESG reporting, they often improve their own scores—while quietly shifting environmentally or socially harmful activities to subsidiaries, especially those operating in countries with weaker institutions. Tom and Stefano discuss how this “ESG arbitrage” works in practice, why subsidiaries see more incidents after mandates are introduced, and how corporate groups restructure—through reallocating resources or divesting risky units—to manage these pressures. The conversation highlights the unintended consequences of uneven global regulation and why coordinated ESG policy matters.Host: Tom Gosling ⁠Contributor: Dr Stefano CascinoRead Stefano Cascino's paper, co-authored with Maria Correia: Behind the Corporate Veil: How Business Groups Arbitrage ESG Disclosure MandatesTo learn more about the Initiative in Sustainable Finance (ISF), visit ISF's website (⁠⁠https://www.fmg.ac.uk/isf⁠⁠). ⁠

Alperen Gözlügöl and Tom Gosling discuss the role that credit substitution plays in sustainable finance. One theory of change in sustainable finance is that directing credit allocation away from dirty firms and towards clean firms can cause the former to shrink and the latter to grow. In this interview, they discuss the ways in which credit substitution can cause this to break down. Putting pressure on bank credit can simply cause a shift to private credit. Differences in sustainable finance regulation across territories can result in shifts in financing and business activities. And even within regions, inconsistent sustainable finance regulation across different subsections of finance can create opportunities for credit substitution. Without a high level of consistency across and within regions and a holistic approach to regulation, credit substitution has significant potential to undermine sustainable finance goals.

Tom Gosling talks to Dimitri Vayanos about the impact the green investors can have on stock prices by divesting from dirty firms and investing in green firms. There's a debate in the academic literature about whether the impacts are negligible or substantial. Using a theoretical model, Dimitri and his co-authors identify a significant but modest impact on cost of capital, measured in a few tens of basis points and share price impacts over a decade of around 10%. So noticeable, but not transformative in the context of the green transition.  Host: ⁠⁠Tom Gosling⁠Contributor: Dimitri VayanosRead Dimitri Vayanos's paper, The Impact of Green Investors on Stock Prices, co-authored with Gong Cheng, Eric Jondeau and Benoît Mojon.

Tom Gosling interviews Kim Fe Cramer, Assistant Professor of Finance on the compulsory CSR spending mandated for large Indian firms. They discuss how firms choose their CSR priorities and where they spend the money. CSR spending is focussed on a firm’s area of competitive advantage so is efficient, but is focussed in their home region, which often means that richer regions benefit from higher CSR spending, raising questions about equity.

Host: Tom GoslingContributor: Martin OehmkeTom Gosling interviews Professor Martin Oehmke on how bank capital rules might integrate climate risks. They debate whether rules can be used to incentivize green lending—or whether this would backfire—and why capital requirements can't play the same role as a carbon tax.Read Professor Martin Oehmke's paper Green Capital Requirements To learn more about the Initiative in Sustainable Finance (ISF), visit ISF's website.
