The Green Ventilation Corridors network in Stuttgart, Germany is an implemented nature-based solution coupled with regulatory policies and incentives. Within this initiative, Green ventilation corridors were created to enable fresh air to sweep down from hills surrounding the city (4).

Overview
Nature-based solution
- Grey infrastructure featuring greens
- Alley or street trees and other street vegetation
- Railroad bank and track greens
- Green parking lots
- Parks and urban forests
- Pocket parks/neighbourhood green spaces
- Green corridors and green belts
Key challenges
- Climate action for adaptation, resilience and mitigation (SDG 13)
- Climate change mitigation
- Green space, habitats and biodiversity (SDG 15)
- Habitat and biodiversity restoration
- Green space creation and/or management
- Environmental quality
- Air quality improvement
- Noise reduction
- Inclusive and effective governance (SDG 16)
- Effective management
- Health and well-being (SDG 3)
- Creation of opportunities for recreation
Focus
Creation of new green areas
Project objectives
1. Preserve and channel cool air throughout the city (1)
2. Connecting rural areas with the city center (1)
3. Prevent urban heat island effect and poor air quality (2)
4. Enhance biodiversity (2)
5. Support health and wellbeing of citizens providing more recreational spaces (5)
Implementation activities
The following implementation activities have taken place;
1. Production of the urban climatic map
2. Introduction of new building regulations
3. Creation of the climate-relevant ventilation lanes, parks and green corridors (5, 7)
Climate-focused activities
Climate change mitigation:
- Increase green urban nature for carbon storage (wetlands, tree cover)
- Improve carbon sequestration through selection of more adaptable species
Biodiversity conservation or restoration-focused activities
Biodiversity restoration:
- Restore species (native, endangered, or unspecified)
- Restore ecological connectivity
Main beneficiaries
- Citizens or community groups
Governance
Management set-up
- Government-led
Type of initiating organisation
- Local government/municipality
Participatory approaches/ community involvement
- Dissemination of information and education
Details on the roles of the organisations involved in the project
Verband Region Stuttgart (the association of regional cities and municipalities) and the City of Stuttgart. The Section of Urban Climatology within the Office for Environmental Protection of the City of Stuttgart contributed with its specialist knowledge. The evaluation and processing of the data for drawing up of the basic material required to produce the maps were undertaken by an external specialist consultant. (1)

... a local policy or strategy?
Yes
(The Regional Plan of Stuttgart (1998) illustrated a system of open-space corridor that channel cooler air down preserved, undeveloped park areas on hillsides and through low-density developed areas, connecting rural areas and the city center. Within the city, shaded parks are connected to the air flow channels wherever possible, providing cooling for local neighborhoods (1). Land use within the green corridors and on the slopes is strictly regulated; the preferred width is a minimum of 100 m (1).
