CDG&Vous, giving the regions a say
Following Paris-Orly 2035, held in 2024, Groupe ADP launched a second major public consultation in 2025 with CDG&Vous. Three months of meetings and discussions to collectively debate and share a long-term vision for the development of Paris-Charles de Gaulle Airport, balancing performance, passenger-appeal, and the green transition.
Paris-Charles de Gaulle by 2035 and 2050
Groupe ADP’s vision for the development of Paris-Charles de Gaulle to 2035 and 2050 is based on two key guiding principles: efficiency, achieved through modularity and a phased approach, and rail connectivity. The projection covers a 25-year period, with the first concrete results in 10 years. The project does not call for a massive, one-time increase in capacity, but rather a phased approach, tailored to the growth of air traffic in Paris and aligned with the expectations of the regions and the entire airport community.
As a true adaptation initiative, this strategic vision is structured around five key areas:
- 1: A large multimodal station
- 2: Phased and modular development
- 3: Optimization of freight operations
- 4: Durable buildings, for quality of life and jobs
- 5: A low-carbon energy hub
By seeking to balance development with decarbonization, and growth with efficiency, this approach yields numerous positive outcomes: a significant reduction in noise, a sharp decrease in greenhouse gas emissions, and improved air quality, as well as the creation of nearly 10,000 jobs by 2035.
A consultation commensurate with the issues at stake
To share this ambitious project with the regions and local residents, Groupe ADP voluntarily launched CDG&Vous, a large-scale public consultation lasting three months and covering approximately 800 municipalities across 9 départements.
To gather feedback and identify expectations, a wide range of tools for expressing opinions and taking part were implemented: a dedicated website, online surveys, and both paper and digital forms. A digital stakeholder report form was created for professionals and organizations. A million informational flyers and prepaid response cards were distributed to mailboxes, and letters and emails were sent to stakeholders.
Meetings and events were also organized close to where local residents live, to provide everyone with accessible opportunities for dialogue. As a result, around 50 public sessions were held in various formats, including plenary meetings, thematic meetings, workshops, and participatory tours.
"We have opted for a public consultation process with an extremely broad scope. We have distributed a flyer to over a million households inviting residents to take part, whether in areas subject to flyover, those included in the noise exposure map, those within our employment area, or any municipalities that share our challenges regarding mobility and energy and are thus affected."
Independent oversight from the CNDP
Taking a proactive approach, Groupe ADP asked the National Commission for Public Debate (CNDP) to support this consultation process. Two independent guarantors ensured compliance with the public’s right to information and to take part, the quality of the proposed procedures, and the equal treatment of stakeholders. After conducting a background study, they formulated methodological recommendations regarding the scope of the consultation, the target audiences, the communication channels, and the methods of engagement.
During the consultation, these guarantors monitored the discussions, ensured that the materials were clear, and verified that the proper arrangements were in place. Their report, released on August 8, 2025, recognized the scope of the consultations and the value of the contributions, and made recommendations that were incorporated into the final consultation report defining Groupe ADP’s commitments.
Expectations and commitments
The large-scale CDG&Vous consultation made it possible to engage with more than 17,000 people and resulted in the collection of approximately 100 stakeholder reports and more than 6,000 contributions.
A clear priority emerged from the feedback received: the development of the CDG2 multi-modal station and a focus on mobility, with high expectations in both areas. Reducing disturbance to local residents was also a major concern and a key topic of discussion. A significant part of the feedback collected reflects a general expectation for noise pollution to be reduced, particularly at night. With over 90% of respondents in favor, there was overwhelming support for the development of low-carbon energy. Finally, there is also a strong expectation regarding employees’ quality of life and jobs. On all these major issues, Groupe ADP has made commitments and provided responses, which are available on the websites cdgetvous.groupe-adp.com and entrevoisins.groupeadp.fr website.
The dialogue will continue within the existing bodies – the Environmental Advisory Committee (CCE) and the Residents’ Assistance Advisory Committee (CCAR) – and will be supplemented by an annual follow-up meeting involving all stakeholders to discuss progress on the commitments made.
