Although green bonds are becoming increasingly popular in the corporate finance practice, little is known about their implications and effectiveness in terms of issuers' environmental engagement. With the use of matched bond‐issuer data, we test whether green bond issues are associated to a reduction in total and direct (Scope 1) emissions of nonfinancial companies. We find that, compared with conventional bond issuers with similar financial characteristics and environmental ratings, green issuers display a decrease in the carbon intensity of their assets after borrowing on the green segment. The decrease in emissions is more pronounced, significant and long‐lasting when we exclude green bonds with refinancing purposes, which is consistent with an increase in the volume of climate‐friendly activities due to new projects. We also find a larger reduction in emissions in case of green bonds that have external review, as well as those issued after the Paris Agreement.

This paper presents new evidence on the impact of the preferential treatment of owner‐occupied housing in the euro area. We find that tax benefits to homeowners reduce the user cost of housing capital by almost 40 per cent compared with the efficient level under neutral taxation. On average, the tax subsidy translates into an excess consumption of housing services equivalent to 7.8 per cent of the value of owner‐occupied housing, or about 30 per cent of financial asset holdings in household portfolios. The bulk of the subsidy stems from undertaxation of the return to home equity, while the average contribution of the tax rebate for mortgage interest payments is driven down by relatively low loan‐to‐value ratios in the data. However, at the margin, the tax‐induced incentive to use mortgage debt to finance the purchase of the main residence is sizeable.

The financial system plays a major role in the transition to a low-carbon economy. We investigate this issue analyzing the recent developments and challenges in the bond and debt markets. First, we study the pricing of green bonds at issuance. We find a premium when green bonds are issued by supranational institutions and corporates while there is no effect for financial institutions. We also document an effect for external review and repeated access to this market. Second, we investigate lending decisions by banks issuing green bonds. Our results show that these lenders reduce their funding towards more polluting segments of the economy but limited to the amount of loans they granted as lead bank in the deal. This mixed evidence about lending suggests that, at the time of issuance, investors may not identify a clear link between the greenbond issued by a financial institution and a green project, which would explain the absence of a green premium for financial issuers.

Using a large international sample of corporate borrowers over the period 2014–22, we study the determinants of issuing green, sustainability and social (GSS) bonds. First, we document a remarkable growth of the GSS segment in the most recent years, possibly spurred by the public commitment towards financing a sustainable economic recovery after the COVID-19 pandemic. The results from a multinomial logit for the choice of bond type confirm that countries’ sustainability stance acts as an incentive for corporate access to the sustainable bond segment. Moreover, borrowers in sectors that are green or can become green, as well as those that have already issued and committed to external assurance on the GSS segment, are more likely to raise funds with non-conventional securities.
