## Summary

The Department for Transport commissioned specialist capacity-building services to help governments in emerging markets and developing economies meet the carbon-market requirements for aviation emissions offsetting under CORSIA. The delivery partner designs and oversees work packages, identifies where UK-funded support can have impact, and mobilises international experts to assist governments. Country-level support covers authorising the release of emissions-reduction credits and reporting the corresponding adjustments to national emissions under Article 6.2 of the Paris Agreement. The work is intended to increase the supply of eligible credits for CORSIA’s First Phase. The service is managed for the Department for Transport, a central government department; delivery is directed at participating governments across emerging and developing economies, rather than a single UK site. The service is categorised as research services (CPV 73110000).

The procurement is complete and was awarded by direct award to the Institute for Global Environmental Strategies, based in Japan. The award is recorded as pending. The award value is £600,000 excluding VAT (£720,000 including VAT). The contract period runs from 19 October 2026 to 31 March 2028, with signature scheduled by 15 October 2026. The Department used a direct award on technical grounds, stating that it had identified only one organisation meeting the requirement for Article 6.2 capacity-building expertise, CORSIA-specific understanding, global expert networks, in-house carbon-market capability and independence from governments and projects that could benefit. The process was not divided into multiple lots: it was a single-lot procurement, described as suitable for SMEs. The stated basis was the supplier’s unique fit for the requirement.

This award demonstrates demand for a delivery partner able to turn international carbon-market rules into practical government support for CORSIA credit authorisation and Article 6.2 emissions reporting. A credible competitor for comparable work would need demonstrable experience helping countries complete Article 6.2 processes, strong knowledge of carbon markets and CORSIA’s emerging needs, and the ability to design country-specific support rather than offer generic training. The chosen supplier’s case also shows the importance of established international reach: access to governments and a broad pool of local and global specialists, plus the judgement to select suitable experts and mobilise them quickly across multiple countries. Practical experience among staff, including Article 6 negotiators and reporting specialists, and impartiality from commercial or political ties to beneficiary governments and projects were central to this buyer’s decision. The requirement was specialist and internationally coordinated, despite being a single-lot service suitable for SMEs.

## Notice

For emissions reduction credits to be eligible under the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), the countries hosting the projects that generate them must provide authorisation to confirm the associated reductions will not also be counted against domestic targets, and make the adjustments to their national emissions reporting required by Article 6.2 of the Paris Agreement. To increase the global supply of credits to meet the level of offsetting obligations expected from CORSIA's First Phase, which must be fulfilled by January 2028, there is a need for capacity building support to assist and train host country governments in the authorisation and reporting process. This procurement aims to appoint a supplier with suitable specialist expertise to act in a delivery partner capacity, designing and overseeing multiple work packages aimed at supporting governments in emerging markets and developing economies to release CORSIA credits. The supplier would assist DfT in identifying impactful opportunities for UK-funded support, and then utilise its international networks to engage suitable experts around the world to deliver targeted support to governments. Support to specific countries would cover issuing the Letters of Authorisation required to confirm their intention to release credits, and/or completing the reporting of corresponding adjustments in accordance with Article 6.2.

### Procurement Information

To DfT's knowledge, targeted carbon market capacity building of this nature, tailored to CORSIA needs, has not been delivered at scale by any organisation. This first-of-a-kind project therefore requires a delivery partner that has knowledge and experience of delivering wider capacity building support related to Article 6.2 of the Paris Agreement, whilst understanding emerging needs relevant to CORSIA. To maximise flexibility and to quickly mobilise appropriate support in a variety of countries, the delivery partner must have existing global networks through which it can access experts capable of providing specific local support, and be able to complement this with its own in-house carbon markets expertise. The delivery partner must also be free from commercial or political links to the governments and projects that may benefit from this support. DfT, working in consultation with the Department for Energy Security and Net Zero, has identified only one organisation that meets these criteria. The requirement directly links to the implementation of Article 6 of the Paris Agreement, in particular Article 6.2, which establishes the framework for cooperative approaches under which host countries can transfer emissions reduction credits. The Article 6 Implementation Partnership (A6IP), part of the Institute for Global Environmental Strategies (IGES) in Japan, was established to directly support implementation of high integrity carbon markets through Article 6 by facilitating global collaboration, knowledge sharing, and capacity building. A global non-profit initiative, it works in collaboration with governments, UN agencies, development banks, other multilateral institutions, and private entities to strengthen countries' capacity for carbon market participation. A6IP is therefore uniquely suitable to deliver this requirement due to the following factors: Membership reach: A6IP currently supports more than 90 partner countries, giving it broader reach than any comparable organisation. Its network also includes 250 organisations and private sector partners. Unique workforce skill: A6IP staff include current and former Article 6 negotiators from around the world, bringing practical expertise in the design and implementation of Article 6. Its recognised Article 6 reporting expertise enables it to translate policy requirements into country-specific implementation support packages. Experience: A6IP have strong experience in delivering targeted carbon market assistance to countries, including support to complete Article 6.2 reporting, giving it the knowledge and capability to understand the technical requirements of countries to complete Article 6.2 processes to release credits for CORSIA Access to and knowledge of external consultants: A6IP's extensive networks give it access to a much-larger pool of relevant consultants and experts around the globe, which would otherwise be difficult to access, and it is has the specialist knowledge and experience needed to assess their suitability to deliver specific aspects of the requirement. Non-profit status: A6IP is a non-profit organisation dedicated to supporting Article 6 Implementation at the global level, in support of net zero by 2050. It is therefore able to advise upon the selection of host countries to support and their specific needs from an informed but impartial perspective.
