Bankers, issuers, investors and other market participants convened last week at the 12th annual Conference of the Principles ( or the Principles ), the premier gathering for participants working in and around the family of environmental, social and governance ( ESG )-labelled bond markets. I’ve always been a supporter of well-designed climate finance and have followed the labelled green bond market and its counterparts since their genesis 20 years ago.
That’s as nice as I’m going to be. Because to me well-designed climate finance is finance that facilitates decarbonization. I suspect I’m not alone in this. But stripped of its carefully managed choreography and viewed without the ESG finance industry’s self-flattering haze, the ESG labelled bond market that’s wrapped itself around the family of Principles has in that context become climate theatre and pageantry.
The people involved in the enormous labelled ESG bond fiefdom need no second request to project their well-rehearsed, self-righteous, mutual backslapping delivered with ‘save the planet’ zeal. While conveniently sidestepping the fact that labelled ESG bonds refinance the already-green economy. Yes, refinance. It’s not about delivering progressive real-world emissions reductions. And more egregious from my standpoint, it’s a market that actively avoids transition funding.
At the same time, the environmental and sustainable finance movement collects enough fees per year to keep thousands of people traversing the globe and living in style: corporate and investment bankers; investors; advisors and consultants; rating agencies, second-opinion providers and verification agents; lawyers, accountants and auditors; data providers; trade bodies; regulators and supervisors; issuers; and more. Whose jobs appear to be about controlling the narrative while ignoring the widening gulf between climate claims and climate outcomes.
Before I go on and to be crystal clear, labelled bonds have clearly helped scale renewable energy, green buildings and clean infrastructure by lowering funding costs and normalising this type of financing in mainstream capital markets with transparency. So, to that extent they have value. But this does not change the structural reality that refinancing already green assets is not the same as financing decarbonization. And that should be the centre of gravity of climate finance.
No emissions reductions, but who cares?
Having long since ceased being about driving decarbonization, the labelled bond market agenda has morphed into preservation and defending a voluntary status quo whose impacts remain largely decorative and ornamental. This is a market working hard to maintain the architecture of its own mythology.
Just think about this for a second. We got to US$8.4 trillion in aggregate issuance of labelled climate-aligned bonds between the first green bond in 2006 and Q1 2026, according to Climate Bonds Initiative. That’s a monumental number. Yet, because the huge flow of labelled climate bonds refinances a much smaller universe of already-green assets, it creates very little in the way of new capital flows to drive climate-change mitigation or adaptation.
Climate-aligned bonds have become a comfort product, a way for both issuers and investors to virtue signal without confronting the structural reality that they’re not cutting emissions. Punitive actions in this fuddy-duddy market are rare. Even amid inconsistent, variable-quality reporting:
And when it comes to sustainability-linked bonds, issuers ( like PKN Orlen, PPC, Enel and A2A ) that failed to hit their sustainability performance targets ( SPTs ) were met not with angry consequence, but with accommodation, as each miss was softened by appeals to shifting conditions, distorted baselines or external shocks.
The market has treated failure as something to be explained away rather than confronted. And this in an asset class where SPTs and key performance indicators are generally weak, step-up coupons are negligible, and no-one seems to bat an eyelid about the truly perverse incentives investors have vis-à-vis this instrument ( that is, they get paid more if issuers miss targets ).
Regulatory outcomes overtake voluntary codes …
Strip away the stagecraft and self-mythology that the ESG bond market is fighting to preserve and the Principles are in any case becoming progressively become surplus to requirements in a world where regulatory taxonomies, formal disclosure regimes and supervisory expectations now define the boundaries of sustainable finance with legal force.
The regulatory dynamic has driven the Principles into reflexive self-preservation. The Comparison of the Green Bond Principles ( GBP ) and the European Green Bond ( EuGB ) Standard report, by the Taskforce on Official Standards and the Green Bond Principles whose release was timed to coincide with the Principles, is a classic defensive manoeuvre. It says the GBP still matter even as the legal EuGB Standard overtakes them with binding rules, taxonomy alignment and regulatory supervision.
This taskforce, incidentally, sits under the executive committee of the Principles, that is, investment bankers, issuers and investors, and is co-ordinated by Credit Agricole CIB and the European Investment Bank. All parties involved have deep commercial and political interests in sustaining the GBP ecosystem. This is no independent authority, but a market run body fiercely defending its own voluntary architecture.
Its report frames the GBP and EuGB as complementary and insists that EuGB issuers should also demonstrate GBP alignment. But, the subtext is unmistakable: the Principles is fighting to remain relevant in a world where regulators now define sustainability with legal force. Less a neutral analysis, the report is a strategic plea for continued deference to a voluntary framework whose authority has been eroded by official standards.
Except …
Regulation has in my view rightly emerged as a force in driving global climate finance because it puts up formal guardrails, creates transparency via mandatory disclosure and introduces jeopardy by enforcing fines and other penalties for non-compliance. But there’s a problem here too: the political drivers of climate regulation constantly change and the initial scope of ambition was monumentally over-blown.
So, in the EU, the sustainable taxonomy has constantly softened to reflect changing political needs and has structurally evolved from a narrow and hardline environmental filter into a pragmatic industrial policy instrument where regional autonomy and energy security now outweigh the original scientific strictness.
The Sustainable Finance Disclosure Regulation is mid-way through a complete redraft because its core purpose failed. The Corporate Sustainability Reporting Directive ( CSRD ) has had its scope narrowed and implementation delayed. The value-chain demands in the European Sustainability Reporting Standards have been limited and exemptions introduced in the name of proportionality and a reduced administrative burden. The Corporate Sustainability Due Diligence Directive has transmuted from a broad, economy wide due diligence regime to a much narrower, large company-only instrument.
In summary, the alphabet soup of EU climate regulation wasn’t fit for purpose in the real world. Regulations were too broad, were introduced too quickly and were too burdensome. Thousands of companies captured by the disclosure regime just lacked the capacity to produce the data required, while large firms were overwhelming their supply chains with information requests they just couldn’t answer.
Requiring companies to measure and report, let alone mitigate, Scope 3 emissions was an analytically incoherent and operationally impossible task because Scope 3 is a political, NGO-driven construct blindly adopted by policymakers and regulators, not an economic construct. So, we’ve had a pivot toward proportionality, narrower scope, delayed timelines, simplified standards and limits because it was clear that the sustainability reporting architecture risked undermining competitiveness and growth without improving transparency.
Finance transition or get out of the way
As I mentioned above, the centre of gravity of climate finance is in the wrong place. Voluntary frameworks won’t move it. Regulation has proved too blunt and too politicized to move it. What will move it is transition finance, that is, actively funding decarbonization pathways in high-emitting, hard-to-abate sectors where the climate stakes are highest. Not refinancing yet more green buildings or renewable energy projects that account for around 80% of green bond proceeds.
The labelled bond ecosystem has steered clear of transition financing because it is optimized for reputational safety, not gritty decarbonization. I don’t know issuers’ intentions any more than I automatically endorse transition targets, but I do applaud credible attempts to reduce emissions in sectors where the climate stakes are highest.
Additionality should be measured in scientifically assessed emissions reductions in hard-to-abate or high-emitting industry sectors.
Transition-linked instruments account for no more than US$20 billion to US$22 billion of the US$8.4 trillion in climate-aligned bonds, equivalent to one quarter of 1%. And most of that is in Japan, where the government has focused on transition funding, not fluffy green refinancing. Japan’s transition framework prioritizes 16 areas, from steel, chemicals and cement to aircraft, ships and semiconductors – exactly where transition finance needs to operate, where there is no fully green alternative.
If an instrument doesn’t change the issuer’s emissions trajectory, it’s climate irrelevant, no matter how green the label. The ESG market needs to address the real decarbonization problem and stop preening itself as a branding exercise.
