The rapid expansion of sovereign environmental, social, and governance (ESG) debt has provided treasuries with unprecedented access to green capital markets.

Yet behind the marketing of sovereign sustainability bonds lies a mounting accountability crisis. Regulatory investigations launched by financial supervisors have revealed that several national treasuries commingled proceeds from green bond sales with general fiscal accounts, indirectly financing carbon-intensive infrastructure.

In response, international standard-setters are drafting mandatory sovereign reporting standards that mirror corporate climate disclosure directives, requiring granular tracing of every dollar allocated to decarbonization.

"If sovereign green bonds are to command a persistent 'greenium', investors must have unshakeable assurance that capital delivers verifiable emission cuts."
