Airports globally beat records in carbon management programme, delivering best carbon savings and engagement growth yet

14 March 2023

  • More than half a million tonnes of CO2 reduced by the global community of airports certified by Airport Carbon Accreditation between May ’21 and May ’22
  • 30% growth in participation with 395 accredited airports worldwide in 79 countries
  • 89 airports achieved advanced levels of carbon management

14 March 2023 – Airports Council International (ACI) today released the annual airport climate action results for Airport Carbon Accreditation, the global carbon standard for airports founded and managed by ACI EUROPE on behalf of airports worldwide.

The past reporting year, running from May 2021 to May 2022, ended with 395 airports spanning 79 countries engaging in carbon management and reduction at one of the six programme levels. The 91 new accreditations reported this year represent the highest growth since Airport Carbon Accreditation’s inception in 2009. Airports have also made great strides in progressing to more stringent levels of accreditation – 86 airports upgraded to a higher level of the programme during the year, with 89 having now achieved advanced levels of carbon management.

Highlighted amongst the programme’s achievements is the sheer diversity of airports now certified. They include airports of all sizes: top global hubs such as London-Heathrow, Istanbul, Doha Hamad International, Singapore-Changi and Dallas Fort Worth are amongst the accredited rollcall, along with capital gateways in all continents such as Abidjan, Athens, Amman, Phnom Penh, Quito and San Jose. Equally, smaller airports serving remote areas, island nations and popular tourism destinations as diverse as Galapagos, Kelowna, Puerto Vallarta, Enfidha Hammamet, Trondheim and Sunshine Coast are proudly counted in their number.

The reporting period covers a timeframe when many airports were facing the profound impact of sluggish and fragile post-Covid traffic recovery on airports’ financial and operational health. In this context, the results achieved serve to reconfirm the unwavering determination of the airport industry to mitigate its impact on the climate.

Delivering tangible carbon savings

The latest carbon reduction and compensation results achieved are equally record-breaking. In the period covered, accredited airports succeeded in collectively reducing the CO2 emissions under their control by 549,643 tonnes, a reduction of -8.1%. This is the largest reduction ever achieved through the programme. In addition, 898,821 tonnes of CO2e were compensated with high quality carbon credits, in line with ACI EUROPE’s Offsetting Guidance1 based on a qualitative assessment of the compensation mechanisms and offset types available on the market.

Niclas Svenningsen, Manager for Programmes Coordination at the United Nations Framework Convention for Climate Change (UNFCCC) said: “The results announced today speak volumes of the global airport industry’s commitment to fighting climate change. Against the backdrop of worsening climate impacts and the window of opportunity to keep the warming below 1.5°C rapidly closing, we need all parts of our global economy to act now. Airports have clearly understood this message and are on the front line of climate mitigation within their spheres of influence and lending their impetus to other industry actors. I commend each and every airport engaged in this collective effort to advance the decarbonisation of the airport industry globally.”  

Olivier Jankovec, Director General of ACI EUROPE, said: “The Airport Carbon Accreditation programme is at the heart of what decarbonising an industry like aviation must be about: aspirational yet deeply practical and actionable, charting not only achievements today but the way forwards for tomorrow. Airports know well the role they play in their communities and the expectations that air passengers have with regard to our shared responsibility for the climate and environment.  The Airport Carbon Accreditation programme provides a framework for measurable progress and demonstrable results.  We are intensely proud of the achievements to date, and the appetite for continued change.”

Alignment with the Paris Agreement

The latest addition to the programme framework, Levels 4 (Transition) and 4+ (Transformation), require airports to align their carbon management and reduction trajectory with the objectives of the Paris Agreement, according to which global warming should be limited to below 2⁰C and ideally 1.5⁰C. Their launch back in July 2019 marked a step-change in the programme’s ambition level, laying the ground to accompany airports of all sizes and locations to reach Net Zero CO2.

The number of airports accredited at these levels reached 322 in the reporting period, pointing to the airport community’s readiness to pursue full decarbonisation in line with, or in some cases even more rapidly than the timelines enshrined in the global climate goals.

Maastricht Aachen Airport is joining the Airport Carbon Accreditation programme

01 December 2022

Maastricht Aachen Airport has achieved the Level 2 'Reduction' accreditation from the Airport Carbon Accreditation programme. 

Maastricht Aachen Airport is actively committed to reducing its CO2 emissions. In recent years, the airport replaced overall lighting with LED, started generating green energy and electrified some of its equipment such as the power generators (ground power units), a baggage conveyor and luggage trolley tractors.

Roel Ubaghs, manager Sustainability & Innovation: "This accreditation is a great recognition for the first steps we have taken as an airport. But we still have a long way to go. In the coming years, for example, we will electrify more vehicles and equipment, switch completely to green energy sources and minimise our consumption of natural gas. The goal is to reduce our emissions to the absolute minimum. We will compensate for the remaining emissions, resulting in a net zero. To this end, we as an airport have drawn up a policy equipped with a plan on how we will actually realise this 'net-zero' ground operation."

Bastiaan de Bruijne, ACI EUROPE General Counsel said: “I commend Maastricht Aachen Airport for their double achievement: entering the Airport Carbon Accreditation programme and becoming directly accredited at its second level. The ‘Reduction’ level is all about kick-starting real-life emissions reductions from within the airport’s direct control and testifies to the airport’s advanced carbon management strategy. I look forward to witnessing Maastricht Aachen Airport’s journey towards ridding its operations of carbon as part of the programme.

Les aéroports français montrent la voie en matière d’action pour le climat [EN version below]

25 November 2022

Sur les 425 aéroports qui réduisent leurs émissions de carbone dans le cadre de l’accréditation carbone mondiale des aéroports, 63 sont français.  Le nombre d’accréditation aux niveaux les plus élevés confirme leur position de leader dans l’action contre le changement climatique
25 novembre 2022 – A l’occasion du 4ème congrès annuel des aéroports français & francophones organisé par l’Union des aéroports français & francophones associés (UAF & FA), l’ACI entend souligner aujourd’hui les résultats obtenus en matière de décarbonation par l’industrie aéroportuaire française dans le cadre de la norme internationale relative à la gestion carbone des aéroports, l’Airport Carbon Accreditation.La France, leader de l’action climatique aéroportuaireAu niveau international, et sur 86 pays représentés dans l’Airport Carbon Accreditation, la France regroupe de loin le plus grand nombre d’aéroports engagés dans l’action climatique. Les 63 aéroports français qui s’attaquent actuellement activement à leurs émissions de CO2 dans le cadre de l’Airport Carbon Accreditation représentent près de 30 % du nombre total d’aéroports accrédités en Europe (219) et 15 % à l’échelle mondiale (425). Ces chiffres en disent long sur la détermination de la communauté aéroportuaire française à traiter les externalités négatives des opérations aéroportuaires.Cette volonté climatique se reflète également dans les niveaux d’accréditation actuellement obtenus par les aéroports français. Une nette majorité d’entre eux, 46, ont été certifiés pour avoir réalisé des réductions tangibles de CO2, du niveau 2 jusqu’aux niveaux les plus élevés du programme. Les aéroports poursuivent leurs efforts pour une transformation plus exigeante et parvenir aux niveaux les plus ambitieux du programme. Depuis le début du quatrième trimestre 2022, 4 aéroports ont été reclassés au niveau 21, 6 aéroports au niveau 32, tandis que les niveaux les plus élevés, les niveaux 4 et 4+, ont été atteints respectivement par l’aéroport Marseille Provence et l’aéroport Lyon Saint-Exupéry.Les deux réseaux aéroportuaires les plus fréquentés de France ont atteint les niveaux d’accréditation les plus élevés : le Groupe ADP exploitant les aéroports de Paris-CDG et Paris-Orly est au niveau 4 « Transformation » et Aéroports de la Côte d’Azur exploitant les aéroports de Nice et de Cannes au niveau 4+ « Transition ». Par ailleurs, VINCI Airports, opérateur aéroportuaire français devenu leader mondial, a obtenu la certification carbone aéroportuaire pour chaque aéroport de son réseau, dans le cadre de sa stratégie environnementale AirPacte. La pandémie mondiale n’a pas freiné le rythme des actions des aéroports en faveur du climat, malgré le choc sans précédent qu’elle a constitué pour le transport aérien.  Depuis le 1er mars 2020, date à laquelle la COVID-19 a été officiellement déclarée pandémie, 22 aéroports français ont rejoint le programme pour la première fois et 25 ont obtenu une accréditation à un niveau plus élevé qu’auparavant.
Le projet Engagement des Aéroports pour la Sobriété Energétique et l’Environnement (EASEE)En 2020, l’UAF & FA a mis en place une nouvelle initiative, en partenariat avec Eco CO2 3, visant à permettre aux petits aéroports en France de surmonter les obstacles à leur engagement dans l’action climatique.  Les partenaires ont reconnu que la gestion carbone dans les aéroports nécessitait des ressources importantes, tant financières que humaines, ce qui limitait souvent la capacité des petits aéroports à s’engager en faveur de la décarbonation. Le nouveau projet, dénommé EASEE (Engagements des Aéroports pour la Sobriété Energétique et l’Environnement), fournit un accompagnement technique et financier sur mesure par le biais d’un mécanisme public (le dispositif Certificats d’Economies d’Energie) – permettant ainsi directement aux aéroports d’être accrédités au sein de l’Airport Carbon Accréditation, quelles que soient leur taille ou leurs capacités financières.Depuis sa création, le projet EASEE qui regroupe 73 aéroports a aidé 36 aéroports en France à obtenir la certification Airport Carbon Accreditation, et 374 aéroports supplémentaires devraient être certifiés dans les mois à venir.  A terme, cela devrait porter à 89 le nombre total d’aéroports français participant à l’Airport Carbon Accreditation.  Le projet EASEE reste la seule initiative de ce type à l’échelle mondiale accompagnant les aéroports dans leur parcours vers des opérations sans carbone et une meilleure performance énergétique et environnementale.  Il a été chaleureusement accueilli par l’ACI EUROPE, propriétaire de l’Airport Carbon Accreditation et partenaire de longue date de l’UAF & FA dans ses efforts environnementaux. Olivier Jankovec, Directeur Général de l’ACI EUROPE, a déclaré : « L’ampleur de l’engagement des aéroports français dans la transformation en cours de notre industrie est énorme. 63 aéroports (et ce n’est pas fini!) réduisent maintenant leurs émissions de CO2 et beaucoup travaillent avec leurs partenaires de l’écosystème aéroportuaire pour enclencher également les réductions de CO2 des autres acteurs de la plateforme. Je tiens à féliciter toutes les équipes aéroportuaires qui travaillent d’arrache-pied pour réduire leurs émissions tout en fournissant la connectivité indispensable aux villes et régions françaises. »Il a ajouté : « l’UAF & FA avec son initiative unique s’attaquant à tous les obstacles entravant le chemin de la décarbonation des aéroports et les actions concrètes en faveur du climat donne un exemple à suivre. Je me félicite de cette coopération et de son potentiel pour permettre une décarbonation plus rapide des aéroports. "

French airports leading the way in climate action

Out of 425 airports addressing their carbon emissions within the global Airport Carbon Accreditation, 63 are French. Upgrades to higher levels confirm their pole position in airport climate action.

25 November 2022 – On the occasion of the 4th annual conference for French and Francophone airports organised by Union des Aéroports Français & Francophones Associés (UAF & FA), ACI is today highlighting the French airport industry’s decarbonisation achievements within the global carbon standard for airports, Airport Carbon Accreditation.France - a leader in airport climate actionOn the global stage, and out of 86 countries represented in Airport Carbon Accreditation, France has gathered by far the biggest community of climate smart airports. The 63 French airports currently actively addressing their carbon emissions in Airport Carbon Accreditation constitute almost 30% of the total number of accredited airports in Europe (219), and 15% globally (425). These numbers speak volumes of the determination of the French airport community to rid their operations of negative externalities for the climate.This climate drive is also reflected in the accreditation levels currently held by French airports. A clear majority of them, 46, have been certified for achieving tangible CO2 reductions, from Level 2 up to the highest levels of the programme. French airports keep on raising the bar for deeper business transformation and reaching more ambitious levels of the programme. Since the beginning of Q4 2022, 4 airports upgraded to Level 21, 6 airports upgraded to Level 32, whilst the highest levels, Level 4 and 4+, were achieved by Marseille Provence Airport and Lyon Saint-Exupéry Airport respectively.The two busiest networks of airports in France are at the highest levels of the programme - Groupe ADP operating Paris-CDG and Paris-Orly airports at Level 4 ‘Transformation’ and Côte d’Azur Airports operating Nice and Cannes airports, having achieved across-the-board Level 4+ ‘Transition’ accreditation. In addition, the homegrown French airport operator turned global leader - VINCI Airports has achieved Airport Carbon Accreditation for every airport within its network, as part of its AirPact environmental strategy. The global pandemic didn’t manage to break the momentum for airport climate action in France, in spite of the unprecedented shock it constituted for the aviation industry. Since 1 March 2020, when COVID-19 was officially declared a pandemic, 22 French airports joined the programme for the first time and 25 achieved accreditation at a higher level than previously.  Carbon management made EASEEIn 2020, UAF & FA set up a new initiative in partnership with Eco CO23  aimed at removing hurdles for smaller regional airports in France to get on board with climate action. The partners recognised that comprehensive carbon management at airports required significant resources, both financial and staffing, often limiting smaller airports’ ability to act upon their commitment to decarbonisation. The new project, called EASEE (Engagements des Aéroports pour la Sobriété Energétique et l’Environnement), provides technical support, tailor-made guidance and financing through a public mechanism (“Certificats d'économies d'énergie”) – thus directly empowering airports to become accredited within Airport Carbon Accreditation, no matter their size or financial capabilities.Since its inception, EASEE has supported 36 airports in France to get certified under Airport Carbon Accreditation, with an additional 374 airports expected to become certified in the coming months. This is set to bring the total number of French airports participating in Airport Carbon Accreditation to 89. EASEE remains the only such initiative on the global scale accompanying airports on their journey to carbon-free operations and improved energy and environmental performance. It has been warmly welcomed by ACI EUROPE, the owner of Airport Carbon Accreditation and a long-standing partner for UAF & FA in their environmental endeavours.Olivier Jankovec, ACI EUROPE Director General said: “The sheer scale of French airports’ engagement in the ongoing transformation of our industry is tremendous. 63 airports (and counting!) are now reducing CO2 and with many working with their airport communities to also trigger third party reductions along the wider aviation eco-system. I would like to congratulate the teams hard at work to achieve emissions reductions whilst delivering the much needed connectivity to French cities and regions.”He added: “UAF & FA with their unique initiative tackling all obstacles on the way for airports to engage in concrete climate action are setting an example for others to follow. I am grateful for this cooperation and its potential to unlock faster decarbonisation.”

Airports step up climate efforts in line with the Paris Agreement

10 November 2022

5 more airports upgrade to the highest levels of Airport Carbon Accreditation as COP27 unfolds, showcasing the unwavering climate ambition of the industry

10 November 2022 – As the landmark UN climate summit, COP27, is underway in Sharm El Sheikh, ACI has today announced the latest developments in its Airport Carbon Accreditation programme, highlighting the advances made by the global airport community to address the climate emergency.

Airport climate action – continuously raising the bar

Against the background of climate impact worsening, and the window of a +1.5°C world rapidly closing, the focus is more than ever on moving from commitment to concrete and tangible action. The airport industry has been working tirelessly to reduce its carbon emissions through Airport Carbon Accreditation since 2009 – delivering concrete reductions of emissions under their direct control year after year, as well as engaging with their business partners to foster carbon reductions by third parties active within their premises.

In 2020, noting the increased need for deeper carbon cuts and in step with the rising ambition of airports around the world expressed in the industry’s commitments to Net Zero by 20501, ACI launched the first major, structural change to the programme since its inception: two new accreditation levels - Level 4 Transformation and Level 4+ Transition crucially linking airports’ climate efforts with the objectives of the Paris Agreement.

The introduction of these two new levels marked a shift in the ambition level of the programme, by setting out further obligations for accredited airports to formulate a long-term climate objective in line with the 1.5°C or 2°C pathways outlined by the IPCC, and defining a concrete plan to achieve it, including interim milestones to measure progress and take stock of the realised CO2 curbs. The two new levels have also gone beyond focusing on absolute emissions reductions of Scope 1 and 2 emissions by requiring airports to map carbon emissions from an extended number of sources and establish formal partnerships with companies active at their sites to guide and help them in decarbonising.

Since the launch of the two new levels, 43 airports around the world, including major hubs and regional airports alike, have already embraced their ambition. A total of 20 airports have achieved Transformation (Level 4) and 23 airports upgraded to Transition (Level 4+). Today, another five airports have met all the stringent requirements to receive these accolades. Level 4+ was achieved by London City (United Kingdom) and Lyon (France) airports, while San Francisco International (United States), Marseille Provence (France) and Zurich (Switzerland) airports secured Level 4.

Receiving praise from the UNFCCC

Airports’ extensive climate efforts within the Airport Carbon Accreditation programme have been applauded by the United Nations Framework Convention on Climate Change (UNFCCC).

Niclas Svenningsen, UNFCCC Manager, Outreach said: “To achieve the deep transformation needed for sustainable development and stabilisation of global temperature, we must require commitments and participation from all sectors and levels of society. I commend airports for their continued efforts to map and reduce their CO2 emissions year by year, as well as to engage their business partners in this endeavour. The Airport Carbon Accreditation programme is evolving in step with the level of urgency to act now for our climate. Having introduced two new more ambitious levels aligned with the ambition of the Paris Agreement and seeing almost fifty major airports around the world embracing them, airports are sending a strong signal to other parts of the economy to follow with ambitious climate action today.”

With more than 400 airports actively addressing their emissions at one of the six available levels, the programme keeps expanding in all world regions, bringing new airports on board with carbon management. The latest entries include: Maastricht Aachen Airport in the Netherlands (Level 2), Ängelholm Helsingborg Airport in Sweden (Level 3+), Aurillac-Tronquières Airport (Level 2) and Le Puy-en-Velay Loudes Airport (Level 2) in France and three Brazilian airports: Florianópolis Hercílio Luz, Vitoria International and Macaé - Joaquim de Azevedo Mancebo all joining at Level 1.

The momentum for airport climate action can also be measured through upgrades achieved at the initial levels of the framework. Aberdeen Airport in Scotland upgraded to Level 3+ ‘Neutrality’. Saint-Nazaire Montoir and Nantes Atlantique airports in France have met the demands of Level 3 ‘Optimisation’, as did Aguascalientes Airport (Level 3) in Mexico. Level 2 ‘Reduction’ was achieved by La Rochelle, Ancenis, Le Havre-Octeville and Limoges airports in France, while in Latin America and the Caribbean, Martinique Aimé Césaire, and three Mexican airports: Hermosillo, Tijuana and Los Mochis are now actively reducing their emissions at this level.




Groupe ADP steps up climate action at Paris-CDG, Paris-Orly and Paris-Le Bourget

07 November 2022

Three Parisian airports in Groupe ADP's international network are now transforming their operations to allow deeper CO2 emissions cuts in alignment with the ambition of the Paris Agreement. Paris-Charles de Gaulle, Paris-Orly and Paris-Le Bourget airports have successfully upgraded to Level 4 'Transformation' of Airport Carbon Accreditation, bolstering climate action in and around the three key airport sites for the French capital. 

At this recently introduced level, airports are required to set up a long-term absolute carbon emissions reduction target, aligned with the IPCC 1.5°C or 2°C pathways, as well as strengthening their stakeholder engagement to achieve carbon reductions across the entire airport site. The commitment to absolute emissions reductions needed at this level is a major step on the trajectory to reaching net zero emissions.

African airports accelerate action to reduce carbon emissions

24 October 2022

25 airports in Africa now address their emissions within the Airport Carbon Accreditation programme, with new entries announced at the ACI Africa/World Annual General Assembly in Marrakesh, Morocco

24 October 2022, Marrakesh, Morocco – As the global community of airport operators and aviation stakeholders gathers in Marrakesh, Morocco for the 2022 ACI Africa/World Annual General Assembly, Airport Carbon Accreditation has today announced new entries and upgrades to higher levels of accreditation achieved – with a particular focus on airports in Africa.

The conference host, the Moroccan Airports Authority (ONDA) has met all the requirements to accredit two more airports within its network: Rabat-Salé Airport and Fès Saïss Airport, both joining the collective airport climate action at Level 1 ‘Mapping’. In addition, the two busiest airports operated by ONDA, Marrakesh Menara Airport and Casablanca Mohammed V Airport, succeeded in upgrading to Level 2 ‘Reduction’ - the level at which airports are required to provide evidence of tangible CO2 reductions of emissions under their direct control.

In Tunisia, Monastir Habib Bourguiba International Airport operated by TAV Airports joined the programme directly at Level 2 ‘Reduction’, following in the footsteps of Enfidha Hammamet International Airport, the first airport to become accredited in the continent and also the very first to reach Level 3 ‘Optimisation’. At Level 3, airports are not only achieving scope 1 and 2 CO2 reduction but also activating their business partners and stakeholders operating at the airport site to get them involved in measuroing and reducing their own carbon emissions. La Réunion Roland Garros Airport is the only other airport in the African region to ever reach this level of carbon management maturity. There is currently one carbon neutral airport on the continent, Abidjan Félix-Houphouët-Boigny International Airport in Côte d'Ivoire.

In total, 25 African airports1 in 13 countries are currently addressing their carbon emissions at one of the six levels available through the Airport Carbon Accreditation framework. They jointly cover more than 40% of African air passenger traffic (as per 2019 traffic levels).  

Ali Tounsi, Secretary General of ACI Africa, said: “I am delighted to witness more and more African airports joining the Airport Carbon Accreditation programme and progressing to its higher levels. These achievements show that airports in the region are already contributing in very tangible ways to ICAO’s Long Term Aspirational Goal of net zero CO2 for international aviation by 2050 – as they are addressing and eliminating emissions under their own control, while also increasingly working with businesses operating at their premises to influence further CO2 reductions. Today we celebrate the achievements of the carbon accredited airports and encourage all African airports to join the momentum.”

Global results  

Airport Carbon Accreditation has seen an unprecedented growth in new accreditations in the past two years, despite the devastating impact of the COVID-19 pandemic and the ensuing crises. Globally, there are now 420 accredited airports, with the regional breakdown as follows: Africa (25), Asia-Pacific (65), Europe (214), Latin America & the Caribbean (57) and North America (59). Carbon accredited airports cover almost half of the world air passenger traffic, at 49.4% (as per pre-pandemic traffic levels).

San Diego International Airport reaches the highest level of Airport Carbon Accreditation!

10 October 2022

San Diego International Airport (SAN) in the US has achieved the highest level of certification within Airport Carbon Accreditation – Level 4+ ‘Transition.’

The airport achieved this certification through a series of programs that have increased the use of carbon-free electricity and all-electric vehicles, facilitated carbon-emission reductions by airline and rideshare partners, and enabled carbon-offset purchases by our passengers, among other efforts.

SAN is one of only three North American airports to achieve Level 4+ ‘Transition’ certification and the only airport in California to reach the milestone. To achieve Level 4+, SAN has demonstrated that it continues to reduce carbon emissions under its direct control (i.e. emissions from building energy use and fleet vehicles), is on a trajectory to meet international Net Zero emission targets through implementation of its carbon management plan, has offset its remaining direct carbon emissions, and has effectively partnered with tenants responsible for Scope 3 emissions at the airport.
