Do green bonds reduce climate transition risk?

About this episode

Green bonds make up about 4% of the global corporate bond market, with more than $1 trillion outstanding. Their proceeds go to projects with environmental benefits. The open question for investors is whether holding one lowers their exposure to climate transition risk.

This episode explores our research into that question. We assessed transition risk across more than $24 trillion of outstanding corporate debt under a range of IPCC and NGFS climate scenarios to 2030.

What you’ll hear

Under 1.5°C net zero scenarios, more than $1 trillion of corporate debt faces a carbon cost liability of at least 90% by 2030. Under Paris-aligned 2°C scenarios, 71 companies still face extreme liability on their debt.

Green bonds offer little protection. We found 18% of them carry significant transition risk by 2030, concentrated in a few heavy-emitting industries led by electric utilities. The risk sits with the issuer, not the bond. An oil and gas company can fund a renewable project with a green bond while most of its income still comes from fossil fuels.

For investors, lowering transition risk means backing companies that are cutting emissions and setting measurable targets.
