Logo of the programme

Airport Carbon Accreditation is a global carbon management programme for airports that independently assesses and recognises airports' efforts to manage and reduce their CO2 emissions. Aircraft emissions, which are many times greater than airport emissions, are not included in the programme. The airport industry accounts for 5% of the air transport sector’s total carbon emissions.[1]

The programme was launched by European airports' trade body ACI EUROPE at their Annual Congress in June 2009.[2] It is independently administered by Environmental Minds,[3] an international consultancy firm. The programme provides airports with a common framework for active carbon management with measurable goal-posts. Individual airport carbon footprints are independently verified in accordance with ISO 14064 (Greenhouse Gas Accounting) on the basis of supporting evidence. Claims regarding airports' carbon management processes are also independently verified by a group of 117 independent verifiers,[4] based in 36 countries.

## Levels

### Level 1: Mapping

To achieve Level 1 accreditation, an airport must meet the following qualifications:

* Be able to determine ‘operational boundary’ and the emissions sources within that boundary which are Scope 1 and Scope 2 sources, as defined by the Greenhouse Gas Protocol.[5] The operational boundary in the context of carbon accounting defined the manner in which the airport measures and manages its GHG emissions.[6]
* Be able to collect and process data and calculate the annual carbon emissions for those sources.
* Generate a carbon footprint report.[5]

For airports, ACERT, the Airport Carbon and Emissions Reporting Tool, which provided by ACI World, is free of charge to its members and is usually what is used to generate a carbon footprint report.[5]

### Level 2: Reduction

To achieve Level 2 accreditation, an airport must meet the following qualifications:

* Meet all above requirements.
* Implement target setting procedures and provide evidence of carbon management procedures that are effective.
* Reduce the carbon footprint by comparing the current year report to prior years.[7]

Carbon management is a broad topic and includes the following processes:

* Low carbon/energy policies
* Senior committee or body has responsibility for climate change/carbon/energy matters
* Fuel and energy monitoring
* Carbon/energy reduction targets
* Actions, programs or control mechanisms to ensure operations minimize emissions
* Emissions impact of investments are analyzed
* Awareness training about emissions
* Self-assessment and Auditing to monitor progress towards improvements
* Communication emissions performance[7]

### Level 3: Optimization

To achieve Level 3 accreditation, an airport must meet the following qualifications:

* Meet all above requirements.
* Widen the scope of its carbon footprint to include a range of Scope 3 emissions.
* Scope 3 emissions to be measured include, amongst others:
* landing/take-off cycle emissions.
* surface access to the airport for both passengers and staff.
* staff business travel emissions,
* Evidence of engagement with third party operators to reduce wider airport-based carbon emissions.[8]

### Level 3+: Neutrality

To achieve Level 3+ accreditation, an airport must meet the following qualifications:

* Meet all above requirements.
* Offset Scope 1 and 2 carbon emissions, as well as emissions from business travel, using internationally recognized offsets.

Carbon neutrality, or net-zero emissions, is achieved when any residual airport emissions are compensated through the purchases of carbon credits.[9]

### Level 4: Transformation

To achieve Level 4 accreditation, an airport must meet the following qualifications:

* Meet all above requirements.
* Policy commitment to absolute emissions reduction.
* Form a long-term absolute carbon emissions reduction target.
* The target amount and date shall be aligned with the IPCC 1.5 °C or 2 °C pathways
* Carbon Management Plan development with targets. Each airport shall define its trajectory to achieve its carbon emissions reduction target as well as the actions it expects to implement to remain on that trajectory.
* Stakeholder Partnership Plan development. The plan shall demonstrate that the airport actively drives third parties at the airport towards delivering emissions reductions themselves via their own reduction plans or through measures initiated by the airport operator.[10]

### Level 4+: Transition

To achieve Level 4+ accreditation, an airport must meet the following qualifications:

* Meet all above requirements.
* Offset remaining Scope 1 and 2 carbon emissions and emissions from staff business travel using internationally recognized offset.[11]

### Level 5: Topmost Level of Airport Carbon Accreditation

To achieve Level 5 accreditation, an airport must meet the following qualifications:

* Submit a verified carbon footprint for Scope 1 and 2 emissions and all relevant categories of Scope 3 emissions as per requirements of the GHG Protocol Scope 3 Guidance
* Reach and maintain ≥ 90% absolute CO2 emissions reductions in Scope 1 and 2, and commit to Net Zero in Scope 3 by 2050 or sooner.
* Credible carbon removals for the residual emissions are applied.
* Carbon Management Plan (CMP) fully developed outlining the steps to achieve emissions targets.
* Stakeholder Partnership Plan is fully developed to achieve Net Zero for Scope 3 emissions by engaging with the value chain and actively drive third parties at the airport towards delivering emissions reductions themselves with regular milestones in line with their sectors Net Zero frameworks and commitments.[12]

## Official endorsements

The initiative is a direct consequence of the resolution on Climate Change adopted in June 2008 by the ACI EUROPE annual assembly,[13] and has been endorsed by both the European Civil Aviation Conference and EUROCONTROL. The administration of Airport Carbon Accreditation is overseen by an independent Advisory Board, members of which include representatives of the United Nations Framework Convention for Climate Change (UNFCCC), United Nations Environment Programme (UNEP), European Civil Aviation Conference (ECAC), the European Commission, EUROCONTROL, Federal Aviation Administration (FAA) and Manchester Metropolitan University. On 30 November 2011 it was announced that the International Civil Aviation Organization (ICAO) was also formally supporting the programme, and taking a seat on the independent advisory board.[14]

In addition to European Commission participation on the Advisory Board, the then European Commission Vice President responsible for Transport Siim Kallas has strongly supported the scheme, participating in the presentation of accreditation certificates at several European Airports, including Charles de Gaulle, Orly, Brussels and Budapest Airports. He has also stated that he believes the initiative "is playing a crucial role in helping move European aviation onto a more sustainable footing."[15]

## Global use

The programme has expanded beyond Europe on 30 November 2011, having been formally extended to the Asia-Pacific region at ACI Airport Exchange conference in Abu Dhabi, organised by ACI ASIA-PACIFIC.[16] The first airport to become accredited within this region was Abu Dhabi International Airport which achieved 'Mapping' level.[17] Since then, 38 airports from the region joined the community of accredited airports. The programme was further extended with the African region of ACI joining the community in June 2013.[18] The launch of Airport Carbon Accreditation in Africa was coupled with the official certification of the first African airport to the programme, Enfidha-Hammamet International Airport in Tunisia,[19] which was certified at the 'Mapping' level. In June 2014, at ACI EUROPE's Annual Congress in Frankfurt the Airport Carbon Accreditation programme celebrated two important milestones in its story: its 5th anniversary together with crossing the threshold of 100 airports participating in the programme.[20]

Shortly thereafter, in fall 2014, the programme became global,[21] with its official launch in North America, followed by its introduction in the region of Latin America and the Caribbean. Having already achieved significant results in 5 continents, the launch of Airport Carbon Accreditation in this region, in partnership with ACI Latin America & the Caribbean, marked the decisive moment when the programme became the global standard for carbon management at airports.

In 2015, a new interactive website, www.airportco2.org,[1] was launched at the end of Year 6 of Airport Carbon Accreditation – the year of the global expansion of the programme. This microsite was created to promote the programme in more accessible language and to communicate the annual results achieved by participating airports. It continues to present key figures from the programme, both globally and per region, in a more visual and engaging way.

## At Paris Sustainable Innovation Forum (COP21)

The COP21 Conference in Paris in December 2015 was an important milestone for the Airport Carbon Accreditation programme. On the occasion of its presentation at the Conference, the European airport industry committed to increasing the number of carbon neutral airports to 50 by 2030.[22] Following the announcement of this commitment, ACI EUROPE and the carbon standard Airport Carbon Accreditation signed a partnership with the United Nations Framework Convention on Climate Change (UNFCCC), at a special side event.[23] The partnership agreement committed ACI to supporting the UNFCCC's 'Climate Neutral Now'[24] campaign, while the UNFCCC would support airport climate action at airports, with a particular focus on carbon management by airports through Airport Carbon Accreditation. The organisations agreed also to develop a common work programme and communications plan promoting carbon neutrality at airports.

## European airports commit to 100 carbon neutral airports by 2030

In June 2017, at ACI EUROPE's 27th Annual Congress, European airports made a new pledge, doubling the one made during COP21.[25] They committed to 100 carbon neutral airports by 2030. Over 20 airport operator companies signed the new commitment, among which: Groupe ADP, AENA, Aeroporto di Bologna, Aeroport Brest Bretagne, Aeroports de la Côte d'Azur, Bristol Airport, Brussels Airport, Finavia, Heathrow Airport, London City Airport, Geneva Airport, Munich Airport, Aeroporto Internazionale di Napoli, Aeroport Quimper Bretagne, Schiphol Group and Zurich Airport.

## Awards and recognition

The Airport Carbon Accreditation programme has gathered a number of notable climate-action awards. In 2013, the programme reached Top 3 in the World You Like[26] competition,[27] a contest in which businesses, NGOs and local authorities can participate by showcasing their climate-friendly solutions, run by the European Commission's Directorate-General for Climate Action. The Airport Carbon Accreditation programme was chosen out of 269 low carbon projects in Europe – and the only transport project in the Top 3. It was recognised as an efficient and innovative climate solution that is making a real difference in helping airports address their CO2 emissions. In May 2014, the airport industry's efforts to address its carbon emissions received the Highly Commended prize at the annual global International Transport Forum (ITF) Awards issued by the Organisation for Economic Cooperation and Development (OECD).[28] The voluntary climate change initiative Airport Carbon Accreditation was named as one of two runners-up for the ITF's Transport Achievement Award.

Only a month later, in June 2015, the animation "Life is about Movement",[29] created to highlight the essence of the programme, was awarded the Gold Totem prize in the "Businesses & Eco-Performances" category at the 4th Deauville Green Awards 2015.

In 2016, Airport Carbon Accreditation was featured in the first ever European Aviation Environmental Report,[30] published by the European Commission, in very positive terms as one of the innovative initiatives of the airport industry to tackle environmental challenges.

## Current state

As of 2017, 192 airports across the world are certified at one of the four levels of Airport Carbon Accreditation. These airports handle 2.7 billion passengers a year, 38.4% of global air passenger traffic. 35 airports are carbon neutral – the latest to reach this level was Helsinki Airport. There are now 28 carbon neutral airports in Europe, 5 in Asia, 1 in North America and 1 in Africa.

### Europe

As of June 2025, there are 286 airports in Europe with Carbon Accreditation.[31]

### Asia Pacific

Delhi's Indira Gandhi International Airport was the first carbon neutral airport in Asia-Pacific region. There are now 38 carbon neutral airports with recent entrants including Gold Coast and Hobart (both in Australia) as well as Muscat International Airport and Nadi International Airport (Fiji) – which have all started their journey to active carbon management, becoming accredited at Level 1 Mapping. Mumbai International Airport and Bangalore International Airport are the latest airports to become carbon neutral in the region.

## Counting the CO2 reduction

| This earth needs to be updated. The reason given is: This information seems to be out of date. Please update this earth to reflect recent events or newly available information. (June 2025)

|

From July 2014 to June 2015, the programme has allowed a reduction comparable to the annual CO2 sequestered by 1,496 acres of forest. We could have powered almost twice as many households as compared to the year 4 result in the sixth consecutive year of the programme. Following years are bound to beat these figures, with a number of accredited airports at high levels rising.[35]
