Gold Standard has been approved by the International Civil Aviation Organization (ICAO) to supply eligible emission units for the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA)’s Second Phase, covering the period 2027 to 2029. 

Gold Standard is proud to announce its approval to supply eligible emission units for the first part of the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA)’s Second Phase, running from 2027 to 2029. 

 

This approval builds on Gold Standard’s existing recognition under CORSIA’s First Phase (2024–2026) and its earlier approval during the pilot phase (2021–2023). It follows several key steps taken by Gold Standard in recent months to facilitate the supply of CORSIA-eligible credits, including the approval of three insurance policies to manage double counting risk and the first labelling of credits as eligible for Phase 1. 

 

Margaret Kim, CEO of Gold Standard, said: 

 

“Access to markets is essential for accelerating climate action. With this approval, Gold Standard project developers can have greater confidence that their high-integrity credits will meet growing compliance demand. Our role is to help developers of all sizes turn ambition into measurable, science-based impact providing the trusted frameworks and tools they need to bring projects to market efficiently and credibly.” 

 

 

With this announcement, project developers certified under Gold Standard gain longer-term certainty of their ability to sell credits into the CORSIA market, where these meet the International Civil Aviation Organization’s (ICAO) eligibility requirements. 

 

In its decision, ICAO has maintained its existing eligibility restrictions for Gold Standard credits under CORSIA’s First Phase and added two new restrictions related to the calculation of the fraction of non-renewable biomass (fNRB) and project baselines. These updates are consistent with Gold Standard’s recent revisions to align fNRB calculations and methodologies with the Paris Agreement framework. This alignment reinforces the importance of these updates in ensuring access for Gold Standard project developers to compliance markets. 

 

Gold Standard will shortly update its Guidelines on the Eligibility of GS-VERs for CORSIA to include new guidance for the Second Phase.
