As this piece is published, I am walking onto a stage to make the case that the voluntary carbon market has experienced is not a collapse, but a correction.
Critically, it has moved out of its first, improvised phase of growth and into something slower, less forgiving, and far more consequential: institutional re‑underwriting.
This is the phase markets enter when good intentions aren’t enough and evidence starts to matter. It is uncomfortable. It is noisier and quieter, all at the same time. But it is exactly how markets become investable.
I’m not here to make a moral argument in support of carbon markets, nor a claim that early approaches were good enough – they weren’t.
Instead, here’s an investment argument: durable markets are built by surviving failure, not by avoiding it.
‘VCM 1.0’ Was Built for Speed, Not Staying Power
In the first era of voluntary carbon, growth was understandably high. Speed mattered. The priority was to prove that nature could be priced at all – that forests, peatlands, soils, and ecosystems could sit inside capital markets rather than outside them.
On that narrow objective, the market succeeded. But speed came at a cost, it always does.
As volumes grew, three structural weaknesses became impossible to ignore.
First: asset integrity. Many credits relied on optimistic baselines and fragile counterfactuals. Permanence horizons were often short relative to the expectations of institutional capital, and reversal risk was systematically underpriced. Not every credit was flawed, but the weakest methodologies came to define the market in the eyes of sceptics.
Second: process integrity. Validation and verification systems were never designed for the throughput that arrived. Projects that should have taken years to evidence were pushed through frameworks built for far lower volumes. Oversight struggled to keep pace with ambition, and confidence eroded accordingly.
Third: incentive alignment. The system rewarded speed and scale over durability and quality. That worked while scrutiny was light. Once buyers, regulators, and investors applied serious diligence, the gap between promise and proof became impossible to ignore.
These were not failures of intent. They were failures of structure – and predictable ones for any emerging asset class that grows faster than its governance. VCM 1.0 was about entry. VCM 2.0 is about endurance.
It’s also why at Oxygen Conservation we focused from Day One on building a premium product designed to withstand institutional scrutiny. Not in response to the market’s correction, but in anticipation of it.
Correction Does Not Mean Demise
When confidence fell, prices adjusted, volumes contracted, and the market went quiet. That moment was widely interpreted as failure, even death.
In reality, it functioned as a filter.
Low‑integrity supply did not simply lose value; it lost credibility. And once credibility is gone, it’s incredibly hard to recover, if not impossible. That supply no longer sets prices, attracts serious capital, or shapes the future of the market.
What remains is a smaller, more disciplined market that places far greater weight on evidence, durability, and governance – smaller, slower, and far more serious. Standards are tightening. Methodologies are becoming more scientific. Verification timelines are lengthening rather than compressing. Permanence, additionality, and leakage are no longer marketing language; they are underwriting criteria.
For those who optimised early for durability rather than speed, this shift has accelerated participation rather than delayed it. That is why Oxygen Conservation entered this phase aligned with the market that emerged, not the one that corrected.
Markets do not become investable by avoiding moments like this. They become investable by surviving them.
Geography is the New Risk Premium
As the market contracts around quality, geography has moved from the background to the foreground.
Carbon credits are long‑duration claims on land‑based outcomes. Confidence in those claims depends as much on jurisdictional strength as on ecological performance. Where the land sits, and under which legal system, matters enormously.
This is where the UK stands out.
Clear land tenure, rule of law, regulatory alignment, and enforcement capacity materially reduce non‑market risk. Measurement standards are improving. Data quality is high by international comparison. Disputes can be resolved. Obligations can be enforced.
For investors, this matters because carbon is not traded on hope. It is traded on confidence. Jurisdictions that reduce political, legal, and governance risk lower the cost of capital and increase asset durability.
The UK is also contributing something less visible but equally important: institutional know-how. Methodologies, registries, governance frameworks, and legal structures developed domestically are increasingly shaping how high‑integrity markets function elsewhere.
The UK now doesn’t just export credits, but market infrastructure and intelligence.
Quality Is the Asset
The next phase of voluntary carbon markets will not be built on scale alone. It will be built on quality.
In investable terms, quality means scientific baselines, long‑dated land control, measurable ecological outcomes, transparent verification, and alignment with national policy objectives. These attributes make projects harder to originate and more difficult to replicate quickly. They also make them underwritable.
The UK’s frameworks such as the Woodland Carbon Code and Peatland Code already embody this approach – prioritising conservative baselines, long-term monitoring, and credibility over speed.
As standards rise, supply becomes structurally constrained. High‑integrity nature‑based carbon is emerging as a scarce asset class – not because demand is limitless, but because credible supply is genuinely difficult to create. This scarcity reflects real‑world constraints on land, governance, and long‑term stewardship.
Capital is responding accordingly. Rather than dispersing across large volumes of low‑cost credits, it is concentrating into fewer projects with clearer risk profiles and longer duration characteristics.
Investors are not abandoning carbon. They are underwriting it properly.
The Re-Writing: What Happens Next
The future of voluntary carbon markets will not be driven by sentiment or advocacy. It will be shaped by compliance pressure, capital discipline, and supply constraints.
In the UK, voluntary carbon is also becoming increasingly adjacent to formal policy mechanisms – from corporate transition planning to biodiversity net gain – reinforcing demand for projects that can withstand scrutiny.
Low‑integrity credits are unlikely to recover value or influence future pricing. They have already served their purpose by showing what does not work. High‑integrity projects – rooted in real land and governed by robust frameworks – will not need defending. They will be pulled into portfolios by necessity.
For the UK, the opportunity is not to recreate VCM 1.0, but to define what comes after it. That means prioritising credibility over scale, infrastructure over storytelling, and durability over speed.
So, as I walk onto the stage, the verdict may already feel settled to some. But emerging markets are not decided in rooms like this, nor do they read the Guardian. They are decided over years, through discipline, governance, and long-term capital – three things that Oxygen Conservation is actively helping to build.
Forgive me, I fear I may be at the wrong funeral. From where I’m standing, the voluntary carbon market is not dead. It is leaner, tougher, and far more serious than before. In fact, I don’t think it has ever looked in better shape.
