Global carbon standard launches its new pinnacle at COP28

ACI launched the new topmost level of achievement in its global Airport Carbon Accreditation programme at the 28th COP28.



ACI launched the new topmost level of achievement in its global Airport Carbon Accreditation programme at the 28th United Nations Climate Change conference (COP28). This milestone confirms the determination and readiness of the airport industry to deliver on its ambitious climate commitments and contribute to the decarbonisation of aviation – fully aligning with the goals outlined in the Paris Agreement.  

Introducing Level 5

At the ATAG1 Global Sustainable Aviation Forum taking place at COP28, Olivier Jankovec, Director General of ACI EUROPE, unveiled the programme’s latest and most ambitious yet development: a new accreditation level – Level 5 – certifying airports for: 

  • Reaching and maintaining a net zero carbon balance for emissions under their control (Scope 1 and 2), and 
  • Extending mapping, influencing and reporting requirements for all other emissions (Scope 3).

The introduction of Level 5 builds on the trajectory of evolution set by the introduction of Levels 4 and 4+ in 2020. These earlier levels already certify airports for following a CO2 emissions reduction pathway aligned with the objective of the Paris Agreement to limit global warming by 1.5°C/2°C.

Level 5 thus recognises the ultimate achievement and maturity in airport carbon management, based on the following requirements:

  • Extensive carbon reduction in absolute terms: To achieve Level 5, airports need to reach and maintain ≥ 90% absolute CO2 emissions reductions in Scope 1 and 2 in alignment with the ISO Net Zero Guidelines2 and commit to achieving net zero in Scope 3 by 2050 or sooner.
  • Investment in carbon removal: Any residual emissions need to be removed from the atmosphere through investment in credible carbon removal projects. To guide airports in this endeavour, ACI has analysed the carbon removal options available and outlined the most effective removal strategies in the updated edition of the Airport Carbon Accreditation Offset Guidance Document3.
  • Establishment of a Carbon Management Plan: Level 5 accredited airports need to outline detailed steps to achieve their emissions reduction targets, as part of their Carbon Management Plan.
  • As has been done since the inception of Airport Carbon Accreditation for all accreditation levels, ACI will keep the requirements of Level 5 under regular review based on the latest science to ensure their continued robustness.

Olivier Jankovec, Director General of ACI EUROPE, said: “Since its launch back in 2009, Airport Carbon Accreditation has become the global standard for carbon management at airports – with 557 airports certified across 5 continents to date. While the programme’s requirements and structure have evolved overtime to reflect both science and societal expectations, the launch of Level 5 marks a pivotal shift. The establishment of a reference framework for airports achieving and maintaining a net-zero carbon balance for emissions under their control reflects the fact that airports are starting to deliver on their net zero commitments. Crucially, Level 5 also pushes airports to extend their focus beyond those direct CO2 emissions, by following a comprehensive approach in measuring their Scope 3 emissions and influencing their reduction towards net zero by 2050.”

He added: “Level 5 signifies genuine business transformation, and I wholeheartedly congratulate the trailblazing airports from the Royal Schiphol Group, Christchurch, VINCI Airports and Swedavia  that have pioneered it and met all its stringent requirements.”

The pioneers of Level 5

At the official COP28 side-event, it was announced that ten airports have already secured Level 5 accreditation as part of the pilot programme that took place in 2023, testing the feasibility and rigorousness of the new framework. The global pioneers who stepped onto the stage to receive their hard-earned certificates included:

  • Amsterdam Airport Schiphol, Eindhoven and Rotterdam-The Hague airports in the Netherlands, operated by the Royal Schiphol Group.
  • Beja, Madeira and Ponta Delgada airports in Portugal, operated by ANA Aeroportos de Portugal | VINCI Airports.
  • Christchurch Airport in New Zealand, operated by Christchurch International Airport Ltd. 
  • Göteborg Landvetter and Malmö airports in Sweden, operated by Swedavia.
  • Toulon-Hyères airport in France, operated by VINCI Airports.

Conor Barry, Manager of  Engagement and Climate Action, UNFCCC said: “COP28 is an opportunity for nations to come together and take stock of the progress made globally to reach the ambitious goals of the Paris Agreement. While governments focus on national approaches, there is much to celebrate and commend in the realm of voluntary climate action. I commend airports for their leadership in carbon management, notably by aligning their global carbon standard Airport Carbon Accreditation with the goals set forth by the Paris Agreement, and advancing in step with the rising level of ambition and deeper understanding of the climate science. Achieving the profound transformation needed for sustainable development and global temperature stabilisation requires commitments and participation from all sectors and levels of society. My congratulations go out to all ten pioneers of Level 5 of the Airport Carbon Accreditation standard who are demonstrating leadership to advance immediate climate action.”
