Two kinds of scarcity drove this week's news. In aviation, Brussels is weighing curbs on which credits count for CORSIA that could leave EU airlines facing Phase 1 scarcity. In Europe more broadly, EU leaders set a deadline of early 2027 to finalise the carbon market overhaul, turning months of skirmishing into a schedule. And from Indonesia came a careful analysis: the country's carbon market reopening may yield slower supply than the optimists expect. Each story is about the same thing: who controls supply, and at what speed.
CORSIA's Gate Narrows
Restricting CORSIA-eligible supply would push airlines toward exactly the authorised, high-integrity credits we have argued are the market's future, at prices that reflect the squeeze. With a briefing earlier this month already warning that government approvals lag airline demand, aviation is becoming the tightest demand pocket in the system. For project developers with Letters of Authorisation in hand, that is pricing power. For buyers without them, it is a queue.
Europe Puts Reform on the Clock
The Q1 2027 deadline for finalising the ETS overhaul concentrates everything we have watched since February: MSR revision, benchmark fights, free allocation, and the shape of international credit use. This week's skirmishes, Italy urging frozen benchmarks, a draft aluminium benchmark sparking industry outrage, France outlining its stance, are positioning, not outcomes. Meanwhile Brussels unveiled its AccelerateEU plan to shield consumers from the energy shock, and analysts revised EUA price projections down as emissions fall with the industrial slowdown. The market is being asked to fund a transition through a recession-risk environment; expect volatility around every reform milestone to mid-2027.
Indonesia's Realism Check
The analysis suggesting Indonesia's carbon market reopening will produce slower-than-expected supply deserves respect rather than disappointment. Careful authorisation is what gives Indonesian units their premium credibility, and slow supply into rising demand is not the worst position for a host country. Malaysia also moved this week, considering an oil palm-based carbon credit framework that would put one of the region's most contested commodities inside a crediting system. And in demand news with regional resonance, Amazon agreed to buy 685,000 credits from Indian rice farmers, proof that large buyers are now signing at scale in Asian agricultural supply.
What This Means for Investors
Three lessons. First, CORSIA scarcity is a designed outcome; authorised aviation-eligible supply is the clearest short-duration trade in the market. Second, Europe's 2027 deadline makes every intervening EUA dip a referendum on politics, not fundamentals; the endpoint is a stronger, internationally connected system. Third, Indonesia's slow-and-credible path is a feature: it preserves the integrity premium that distinguishes its supply in a world where buyers like Amazon are scaling across Asia.
