Sustainability frameworks are often judged by the information they ask organisations to report. ACI EUROPE’s newly launched airport strategy asks a more operational question: what should an organisation do next—and how should that influence investment?
Launched on 7 October 2026 at the Joint ACI EUROPE and ICAO EUR/NAT Environmental Protection Seminar in Tashkent, the Sustainability Strategy for Airports 2.0 updates the organisation’s 2019 strategy and covers the period 2026–2030. It combines practical actions, performance indicators, regulatory guidance and airport case studies.
The framework’s significance extends beyond aviation. It illustrates an important distinction between documenting sustainability performance and using sustainability information to manage a business.
For airports, that means bringing emissions, physical climate risks, resource use, local environmental impacts and social considerations into the same strategic conversation.
What has changed: carbon remains central, but no longer stands alone
The revised strategy retains decarbonisation as a central priority while organising action around seven themes:
Decarbonisation and energy transition.
Climate adaptation and resilience.
Local environmental quality and community impacts.
Circular economy and resource management.
Biodiversity, land use and airside ecology.
Sustainable mobility and accessibility.
People and community.
The breadth matters because an airport is more than a source of operational emissions. It is also a physical asset, an employer, a transport interchange, a commercial landlord and a neighbour to surrounding communities.
A project that reduces electricity consumption may support decarbonisation, but it does not automatically address flood exposure, water use, accessibility or local noise concerns.
ACI EUROPE’s approach recognises that these issues need distinct measures while remaining connected through management and investment decisions. Its foreword explicitly positions sustainability as a strategic pillar influencing how airports prioritise, invest, manage risk and create value.
This is not a reason to dilute carbon targets. It is a reason to stop treating them as a complete description of organisational sustainability.
Four maturity stages give organisations a route to action
The strategy introduces a four-level maturity framework: Comply, Embed, Advance and Pioneer.
Each stage describes a different level of organisational practice:
Comply: meet current and anticipated legal and regulatory requirements and establish a baseline.
Embed: integrate sustainability into operations, culture and planning, moving beyond compliance.
Advance: set ambitious targets, lead the organisation’s peer group and deliver measurable outcomes.
Pioneer: drive system-wide change and contribute to the development of wider standards.
This structure responds to differences between airports. A regional facility and a major international hub do not have identical resources, exposure or investment options.
The framework therefore provides a progression rather than prescribing one uniform operating model.
The analytical value is straightforward: a baseline identifies the starting point; management integration establishes responsibility; measurable outcomes demonstrate progress; and collaboration extends influence beyond the organisation’s direct control.
The stages should not be mistaken for a certification awarded automatically by reading or applying the strategy. They are a planning and assessment structure within the guidance.
Double materiality becomes a prioritisation tool
Before selecting actions, the strategy recommends a materiality review.
Its approach asks airports to consider their impacts on the environment and communities, the external factors that could affect future business viability, and the interests of stakeholders such as employees, passengers, shareholders and local authorities.
This brings double materiality into an operational setting.
Impact materiality examines how an organisation affects people and the environment. Financial materiality examines how sustainability-related factors affect the organisation.
For an airport, local environmental impacts and exposure to climate disruption may therefore require attention for different reasons. One concerns consequences for surrounding people and ecosystems; the other may concern operational continuity and asset performance.
The practical lesson for sustainability teams is that a materiality assessment should inform priorities—not simply generate a diagram for an annual report.
A useful assessment should help management identify which decisions require action, who owns them and what evidence will demonstrate progress.
Climate adaptation moves alongside decarbonisation
The updated strategy treats adaptation as the strategic partner of emissions reduction.
It connects climate resilience with infrastructure, operational continuity and asset value. It also identifies the incorporation of adaptation into future physical assets and relevant capital investments as a priority for 2026–2030.
This distinction is important.
Reducing emissions addresses the organisation’s contribution to climate change. Adaptation addresses the ability to operate under changing climate conditions.
An emissions roadmap cannot, on its own, demonstrate that infrastructure is prepared for heat, flooding or disruption to essential services.
For boards and investment committees, the framework suggests a more complete review of capital expenditure: not only whether a project reduces emissions, but whether it strengthens the resilience of the asset and the services it supports.
That is an implication of the strategy—not a claim that every adaptation investment will deliver the same financial return.
Reporting frameworks and sector guidance serve different purposes
ACI EUROPE states that the strategy aligns with the ACI World Global ESG Reporting Framework for Airports and maps airport sustainability topics against international goals and relevant reporting requirements, including CSRD and ESRS.
These instruments should remain distinct.
The new strategy provides sector-specific guidance for organising action and measuring progress. It does not replace the legal requirements applicable to an individual airport, nor does publication of the strategy make every airport subject to the same reporting obligations.
The useful relationship is complementary: reporting requirements establish what qualifying organisations must disclose, while sector guidance can help translate relevant topics into operational actions.
Organisations should still assess their own jurisdiction, reporting scope and applicable implementation timetable.
For businesses outside aviation, the transferable lesson is the architecture—not automatic applicability. A company can learn from the connection between materiality, actions, maturity levels and indicators without presenting itself as compliant with an airport-specific framework.
Performance indicators need clear boundaries
The strategy’s decarbonisation indicators include both emissions intensity and absolute emissions, alongside energy consumption, renewable-electricity share, fleet electrification and other operational measures. It also distinguishes Scope 1 and 2 emissions from Scope 3.
Those distinctions protect the usefulness of the data.
An intensity measure describes emissions relative to activity. An absolute measure describes total emissions. They answer different questions and should not be treated as interchangeable.
Similarly, progress within an airport operator’s direct operations does not establish that all emissions associated with aviation activity have been eliminated.
The strategy also cautions that offsets should complement—not substitute for—direct emissions reductions and advises against carbon-neutral claims without third-party verification.
For communications teams, the implication is to define the boundary before presenting the achievement: which activities, which emissions scopes, which period and which verification process?
The wider lesson: a framework should change decisions
The strongest feature of ACI EUROPE’s update is its connection between sustainability ambition and management practice.
Its structure gives organisations a sequence: identify material issues, establish the baseline, select actions appropriate to their maturity, assign measures and demonstrate outcomes.
For companies reviewing their own sustainability programmes, five questions follow:
Does the materiality assessment influence the investment pipeline?
Are responsibilities shared with operations, procurement, finance and risk management?
Are climate adaptation and emissions reduction addressed separately but coherently?
Do indicators distinguish absolute outcomes from intensity improvements?
Can public claims be traced to a defined boundary and supporting evidence?
These are editorial recommendations drawn from the framework’s design, rather than additional requirements imposed by ACI EUROPE.
The new airport strategy offers a timely example of implementation becoming the central test of a sustainability framework. Its value will depend less on the commitments organisations repeat than on the decisions, investments and measurable changes that follow.
