Demand That Exceeds Supply

Masdar, the Abu Dhabi energy company, placed its first blue bond in London: ? million over five years, rated AA-. The order book reached ?.5 billion, a 2.5-fold oversubscription. Proceeds will fund offshore renewable projects. Iberdrola, for its part, raised ?.6 billion in green bonds on the US market, in two tranches of ? million. Demand exceeded ? billion, more than three times the offer, according to the company.

Credit Quality as a Filter

Both deals share a common thread: strong issuers, identifiable renewable projects and predictable revenue streams. Yet sovereign borrowing rates are at their highest levels in decades in many countries. In such a context, issuer strength and the clarity of financed projects serve as screening criteria for investors. Our reading is that the label attracts, but credit quality and revenue visibility decide the rush to order books. The energy backdrop, with Brent at 109.44 and WTI at 99.92, also underscores the economic stakes of the transition, though no direct link to these subscriptions can be inferred.

Adaptation, Outside the Order Books

Projects without own-source revenue follow a different logic. In Cameroon, the Niger Basin climate change adaptation program awarded four contracts for pastoral water retention structures worth 2.439 billion FCFA, 1.71% below the initial estimate of 2.481 billion. Financing relies on a concessional loan from the African Development Fund, supplemented by counterpart funds for taxes. The structures are to supply livestock with water in the dry season but generate no securitizable revenue streams.

In Brazil, the government plans to share with private concessionaires the losses from extreme climate events that exceed insurance coverage at ports and airports. The 2024 floods at Salgado Filho airport in Porto Alegre serve as an example. Minister Tomé da Franca targets a signing by end-November. The proposal, however, sets no percentage, no amount and no funding source: the state becomes insurer of last resort without its commitment being quantified.

What These Data Do Not Say

Two issuances do not make a market. The file provides neither aggregate sustainable finance volumes nor yield spreads versus conventional bonds, and therefore no measure of any green premium. The Iberdrola figure is published by the company itself. Nothing establishes either that Cameroon and Brazil are representative of global adaptation.

A Proportionate Conclusion

The facts converge on a cautious finding: market capital concentrates on strong issuers and projects with clear revenue, while adaptation depends on public and concessional windows. It remains to be verified, on a broader sample, whether this gap is widening or whether new risk-sharing mechanisms, such as the one Brasília is preparing, can narrow it.
