Overview of the different stakeholders grouped in six different teams.
| TEAMS INVOLVED | STAKEHOLDERS INVOLVED |
|---|---|
| Rennes city practitioners acting as CUSSH contact points | Two members from the city of Rennes act as contact points for the CUSSH project (a project manager from the urban planning department and the head of the health–environment department of the city of Rennes |
| Rennes stakeholders | Rennes decision-makers (elected city representatives) and practitioners, including the Rennes city practitioners CUSSH contact points |
| Local scientific team | Researchers from EHESP |
| CUSSH Rennes team | Local scientific team (EHESP) in collaboration with the engineering consultancy Buro Happold and city practitioners CUSSH contact points |
| CUSSH management team | CUSSH project pilot team (UCL plus LSHTM) |
| CUSSH Scientific team | Academic researchers (including the local scientific team) |

Flow diagram for the Cities Rapid Assessment Framework for Transformation (CRAFT) tool.
Note: Beige indicates the first step of the assessment using the CRAFT tool: policy identification. Orange indicates the second step: environmental impacts. These include greenhouse gas (GHG) emissions, air pollution and indoor air quality, as well as travel-related physical inactivity. Blue indicates the final step of the assessment: health impacts. The arrows between stakeholder participation and the assessment steps represent engagement (e.g. presenting policy choices or showing model results) and receiving feedback from stakeholders.

| ACTION MODEL STEP | ACTIVITIES IN THE RENNES CASE STUDY | PERIOD |
|---|---|---|
| 1. Build relationships and consensus | • Meeting between the CUSSH
management team and the Rennes Deputy Mayor for
Health ➔ In-principle agreement reached | Early 2017 |
| • Deputy Mayor for Health shared the CUSSH project and its ambitions with other Rennes stakeholders and had a meeting between the CUSSH team and the RBUS network | May 2017 | |
| • Rennes workshop dedicated to the CUSSH | May 2018 | |
| • Involvement of Rennes stakeholders including EHESP in the CUSSH project | January 2019 | |
| • CUSSH annual meeting—participation of a Rennes stakeholder | May 2019 | |
| • Signed agreement formalising EHESP involvement in the CUSSH project | October 2019 | |
| • Scope of work agreed following the September 2019 workshop with stakeholders | October 2019 | |
| • Formal collaboration agreements signed between the EHESP and the CUSSH management team, and between the EHESP and Rennes stakeholders | October 2019–February 2020 | |
| 2. Understand the city context | • ‘Kick-off workshop’ in
Rennes in June 2017 ➔ Project plan refined with a view to finalising contract responses to the Wellcome Trust | June 2017 |
| • CUSSH workshop in London with the
Deputy Mayor for Health ➔ Discussion of possible forms of modelling to support interactions between researchers | February 2018 | |
| 3. Synthesise city evidence | • CRAFT modelling tool introduced: retrieve local data | May–September 2018 |
| 4. Synthesise global evidence | • Evidence-based synthesis and briefing reports produced | February–May 2018 |
| 5. Assess if objectives can be met | • Rennes stakeholders requested the
evaluation of new public policies with the CRAFT tool, particularly
public policies related to local mobility and urban
development ➔ Rennes team provided an updated matrix classifying new objectives for the CRAFT tool ➔ Agreement on the correct translation of policies from French to English and corresponding revision of the CRAFT objectives | April 2020 |
| 6. Build and use models |
| May 2018–October
2020 September 2018 October 2018–Oct 2020 February 2020 October 2020 |
| 7. Compare scenarios | • Not yet achieved | |
| 8. Plan together | • Not yet achieved | |
| 9. Develop implementation plans | • Not yet achieved | |
| 10. Implement plans | • Not yet achieved |
