FAQs

How is this different from consultancy reports on Article 6 and CORSIA?

A report answers one question, once. The Hub is a live, structured intelligence engine. Demand and supply forecasts, LoA tracking, futures pricing, sovereign risk and airline exposures are all updated as the market moves. Every datapoint is traceable to its source, so the output is auditable, defensible and shareable with an internal investment committee or regulator.

Which programmes and host countries do you cover?

Coverage spans every CORSIA-eligible programme - Verra, Gold Standard, ACR, CAR and ART TREES today, with GCC, FCPF and Premium T-VER in the pipeline - and every host country that has issued, or is preparing to issue, Letters of Authorisation. The Hub is programme-agnostic: we assess each mechanism against the rule text, not the market narrative

How is sovereign risk scored?

Risk scores combine LoA policy, authorisation history, institutional capacity, NDC conditionality and white-list criteria (e.g. EU and national quality filters). Each score is broken down into its underlying components so you can see exactly why a country screens high or low, and stress-test assumptions against your own thesis.

Where does the pricing data come from?

CORSIA futures pricing is delivered through our partnership with ICE. LoA and CA pricing by host government is aggregated from Sylvera-tracked transactions and public disclosures. Spot pricing for CORSIA-eligible credits draws on Sylvera's existing Market Intelligence price observations and estimates.

Does the Hub include expert content as well as data?

Yes. Subscribers get Sylvera's policy view on key trends, market commentaries for Article 6 and CORSIA, periodic data briefings, a full modelling report, and a quarterly webinar series hosted by our policy team - so data and expert interpretation arrive together.

How is the Hub delivered?

As a dashboard inside Sylvera's Market Intelligence platform, with structured outputs via the Sylvera API for customers integrating into their own tooling. Every deliverable carries a full audit trail of inputs, source references and confidence levels - ready to share with an internal committee or external regulator

Who uses the Hub today?

Airlines modelling CORSIA exposure, sovereigns structuring ITMO supply, developers routing projects through authorisation, traders pricing CORSIA-eligible credits, investors and offtakers diligencing adjusted-credit claims, and insurers underwriting sovereign delivery risk.

What is a corresponding adjustment?

A corresponding adjustment is the accounting step that stops the same tonne of CO2 being counted twice. Under Article 6 of the Paris Agreement, when a country sells emission reductions for use abroad (for example into CORSIA), it has to add those tonnes back to its own greenhouse gas inventory. The buyer can then claim the reduction without the host country also counting it toward its national climate target.

For CORSIA Phase 1, units from host countries with NDCs covering the relevant sector must have a corresponding adjustment applied to be eligible.

What is a Letter of Authorisation (LoA)?

A Letter of Authorisation is the document by which a host country government formally permits specific carbon credits to be used internationally. The LoA identifies the project, vintage, volume, and approved end-use (such as CORSIA, an Article 6.2 bilateral deal, or the voluntary market).

Without an LoA, the registry cannot tag the credits as authorised and the host country cannot apply the corresponding adjustment. In practice the LoA is currently the main bottleneck on supply of CORSIA-eligible credits: ICAO has approved several crediting programmes, but each batch of credits still needs an LoA from the host country.

What makes a carbon credit CORSIA-eligible?

A credit must clear three checks set by ICAO's Technical Advisory Body:

  • Programme. The credit must come from a crediting programme on ICAO's approved list, and under a methodology within that programme's approved scope. ICAO publishes the current list; it includes ART TREES, ACR, CAR, Verra, Gold Standard, and Global Carbon Council, each with specific conditions.
  • Vintage and phase. The credit must fall within the eligible vintage window for the current phase. The Pilot Phase (2021-2023, voluntary participation) accepted vintages from 2016 onward. The First Phase (2024-2026 compliance) requires vintages from 1 January 2021 onward.
  • Authorisation and corresponding adjustment. The host country must have issued a Letter of Authorisation for CORSIA use and committed to applying a corresponding adjustment.

The underlying quality criteria the Technical Advisory Body assesses include additionality, permanence, accurate quantification, no leakage, no double counting, and governance requirements on the crediting programme.
