Airports have many key internal and external stakeholders who must be included in decision-making processes when evaluating options for CDR (see Figure 27). Engaging with stakeholders from the earliest stages of planning will result in the most effective climate action and carbon-reduction or removal plans. High levels of engagement will help build initiatives into each stakeholder’s operations, which leads to more successful efforts to remove and reduce carbon.
The approach to stakeholder engagement will vary as airports across the country have different levels of experience with carbon reduction and net-zero carbon planning. Airports also have different levels of staffing and financial resources. Similarly, airports vary in how they engage their stakeholders, what engagement mechanisms are used, and the level of input desired. For example, larger airports often have well-established and resourced stakeholder engagement mechanisms, such as community advisory groups, roundtables, standing tenant meetings, sustainability committees, and dedicated public-outreach staff. These airports can use their existing resources to bring stakeholders into the conversation about net-zero planning and CDR. In other cases, large airports may find conducting stakeholder engagement on new topics, such as CDR, challenging precisely because there are many other planning and engagement activities occurring simultaneously.
Conversely, although smaller airports typically have fewer staff and financial resources, the number of interested and impacted stakeholders may be more manageable and therefore easier to convene. Despite the challenges airports face, it is still critical to coordinate with stakeholders and have honest and transparent conversations about what is possible and practicable for the airport regarding CDR.
Airports do not control all the emissions associated with their site, as many operations are controlled by tenant stakeholders. Typically, Scope 3 GHG emissions (for example from concessionaires, car rental agencies, aircraft operators, ground transportation service providers and customers) account for over 90 percent of an airport’s GHG emissions inventory (NASEM 2011). Therefore, it is critical that airports seeking to develop and implement carbon-reduction and net-zero carbon plans engage with these entities. While the airport does not directly control the operations and emissions of these stakeholders, airports can influence and inform the stakeholders’ decision-making and create partnerships to achieve deeper carbon reductions than the airport could achieve on its own.
CDR integration in net-zero planning is new for most airports, and while some have been tracking CDR practices, education was identified during the industry interviews as one of the most important outcomes of this ACRP project. Airports can convene large groups of stakeholders for educational purposes and collaborative planning to advance the stakeholders’ knowledge of
net-zero planning, including information about CDR and the role that it can play in meeting net-zero goals for the aviation industry. Developing a common understanding and getting broad stakeholder buy-in will be critical to the planning, financing, implementation and ultimate success of future CDR initiatives at airports. Relevant stakeholders may include, but are not limited to, the following:
For airports with established stakeholder engagement mechanisms and experience developing and implementing a sustainability or carbon-management plan, those same approaches can be used for CDR planning efforts. In addition, ACRP Research Report 220: Guidebook for Developing a Zero- or Low-Emissions Roadmap at Airports (Morrison et al. 2021) provides a detailed
approach to conducting stakeholder engagement for decarbonization efforts that can be applied for CDR planning efforts as well.
ACRP Research Report 220 recommends creating three stakeholder groups to ensure successful planning and implementation phases of a project: (1) a core decision-making team, (2) an advisory team, and (3) an implementation team. The core decision-making team is a group of internal staff who participate in all phases of project planning. As project planning relates to CDR, the core decision-making team should include employees who are deeply involved in sustainability or net-zero project planning and long-term planning and capital development and financing projects. They should have decision-making authority (these employees are not limited to sustainability and environmental staff). The implementation team should include internal and external stakeholders who will advise on the project’s vision and goals, and once developed will ensure that those goals and vision are implemented. The advisory team should be composed of external stakeholders (e.g., local elected officials or city departments, FAA, community groups) and support the two other groups. These three groups can collaborate throughout the phases of a CDR project, from initial road-mapping to concept development and finally to implementation (see ACRP Research Report 220 for a detailed explanation of the recommended stakeholder engagement approach).
Airports will be able to encourage robust stakeholder engagement by communicating and educating stakeholders on how CDR can contribute toward common goals. One frequent challenge of stakeholder engagement is a lack of incentive to participate. Table 12 explains why each stakeholder group is likely to be interested about CDR.
It is important for the airport to encourage stakeholder participation by providing real opportunity for input and the ability to influence the planning process as each group will have a unique perspective. Many of the stakeholder roles will vary depending on the specific discussions, the planning stage, and types of projects under consideration. As with any planning project, considering a range of viewpoints is instructive and can result in a better outcome. It is important to have skeptics, advocates, and everyone in between evaluate and potentially

| Stakeholder Group | Potential CDR Interest |
|---|---|
| National, state, and local government | Social and economic development, increased safety and health, new job creation, environmental health, regulations, improved air quality, common GHG emissions reduction and climate-mitigation goals |
| Airport organization (internal) | Improved air quality, development, financial stability, new technology implementation, removal of CO2 emissions, progress toward net zero, demonstration of leadership |
| Airport employees | Airport initiatives; environmental, social, and governance (ESG) practices; health; safety benefits |
| Airport service partners, tenants, and airlines | Development, ESG practices, economic development, improved air quality |
| Airport customers | ESG practices, environmental sustainability, improved air quality, development, progressive practices, safety |
| Neighboring communities | Environmental impacts, especially relating to air pollution; job opportunities; improved air quality; potential noise complaints from the new technology |
| NGOs | Environmental justice, air pollution, environmental health, community safety and health |
| Suppliers | Development, increase in customer traffic, economic growth, improvement in air quality, education opportunities |
implement CDR at an airport. If, and when, an airport begins to deploy CDR, the communication with its stakeholders must remain consistent.
Support for the stakeholder coordination is provided in Chapter 7 (Section 7.2, Communication Toolkit) and in the associated files within the toolkit, which are provided as supplemental materials on the National Academies website (nap.nationalacademies.org) by searching for ACRP Research Report 270: Carbon Removal at Airports and looking under “Resources.”
Because CDR is a fast-developing field and airports are generally not experts in this topic with few airport industry examples to follow, collective action and collaboration are critical for successfully implementing CDR strategies. During the early stages of planning, airports should identify potential partners with aligning goals as they relate to curbing, and most importantly, removing carbon from the atmosphere. Because CDR is rapidly evolving, partners may be needed to help review new technologies, navigate changing clearances and permitting and regulatory environment, align stakeholders, identify and pursue funding opportunities, and develop CDR projects at airports. Many airports are municipally owned and working with the local city, county, or port authority would be a good starting point for outreach and partnerships. Some of these potential partners are included in the following list:
The research, development, and deployment efforts for CDR are a global effort. Many organizations and institutions are focused on the scaling and accessibility of CDR technology. Table 13 provides a brief overview of relevant entities and resources.
