Sustainable finance—the integration of environmental, social, and governance (“ESG”) issues into financial decisions—is an increasingly important topic. Within companies, sustainability is no longer an ancillary issue confined to corporate social responsibility departments, but a CEO-level issue fundamental to the core business. Within the investment industry, sustainability used to be the exclusive domain of “socially responsible investors” who had social as well as financial objectives, but is now mainstream and includes investors with purely financial goals. This article introduces the RF Special Issue on Sustainability. It highlights three reasons for the rapid rise in sustainable finance—its financial relevance, its contribution to nonfinancial objectives, and investor tastes. It then summarizes the eight articles in the Special Issue, in particular drawing out their contributions to the literature. Finally, we offer ideas for future research

Corporate lobbying positively influences firm innovation outcomes. Firms that engage more in lobbying have more patents, more patent citations, and greater patent value. We establish this causality using instrumental variables estimation. Corporate lobbying plays a role of persuasion and fosters firm innovation by transmitting valuable information to politicians, which enhances firms' external political environment. The impact of lobbying on innovation is more pronounced for firms with comparative advantages in the product market, financial health, ESG performance, and institutional support. These results contribute to a deeper understanding of the role of firms' information value in the political process and provide new insights into how lobbying buffs firm development

We examine whether free-speech protections influence corporate environmental performance. Using the staggered enactment of U.S. anti-SLAPP statutes in a stacked difference-in-differences design from 1990 to 2019, we find that these laws significantly reduce firms’ toxic emissions without curbing economic activity. Anti-SLAPP enactments also promote environmental investment through green innovation, abatement spending, and waste reduction management, and strengthen governance via improved sustainability oversight, ESG-linked executive pay, employee training, and supply chain management. The effects are stronger when stakeholder monitoring is stronger and when managerial incentives embed sustainability goals. Overall, free-speech protections generate powerful environmental benefits

How do banks react to firms’ climate risks? Using almost 80,000 global syndicated loans originated from 2001 to 2021, we study bank lending to fossil fuel firms vis-à-vis other firms. We find that loans to fossil fuel firms are at least 7 % more costly compared to other firms, and even more so toward the end of our sample. However, loan amounts to fossil fuel firms are approximately 22 % larger, implying heavy financing of brown activities. We show that the pricing effects are even stronger for banks with higher reliance on ESG considerations, consistent with the shifts driven by the supply side (bank behaviour). Overall, our findings corroborate the view that banks price in climate risks but continue to heavily lend to polluting firms in the medium term (with an average maturity of four and one quarter years

Our paper analyzes whether a planner should design a taxonomy for sustainable investment products when conventional tools for environmental regulation can also be used to address externalities arising from firm production. We first show that the private market provision of ESG funds marketed to retail investors involves greenwashing , so that a mandatory taxonomy is necessary to generate real effects of sustainable finance . However, the introduction of such a taxonomy can only improve welfare, on top of optimally chosen environmental regulation, if financial frictions constrain socially valuable economic activity. Otherwise, environmental policy alone is sufficient to optimally address externalities

Institutional investors expect infrastructure to deliver long-term stable returns but gain exposure to infrastructure predominantly through finite-horizon closed private funds. The cash flows delivered by infrastructure funds display similar volatility and cyclicality as other private equity investments, and their performance similarly depends on quick deal exits. Despite weak risk-adjusted performance and failure to match the supposed characteristics of infrastructure assets, closed funds have received more commitments over time, particularly from public investors. Public institutional investors perform worse than private institutional investors. ESG preferences and regulations explain 25%–40% of their increased allocation to infrastructure and 30% of their underperformance

We propose and implement a procedure to dynamically hedge climate change risk. We extract innovations from climate news series that we construct through textual analysis of newspapers. We then use a mimicking portfolio approach to build climate change hedge portfolios. We discipline the exercise by using third-party ESG scores of firms to model their climate risk exposures. We show that this approach yields parsimonious and industry-balanced portfolios that perform well in hedging innovations in climate news both in sample and out of sample. We discuss multiple directions for future research on financial approaches to managing climate risk
