The junior research group CoSynHealth from the BMBF funding measure "Junior Research Groups: Climate, Environment and Health" is investigating how conflicting goals and synergies between CO2 neutrality and healthy city scenarios can be solved

The health aspect is often overlooked in scenarios for carbon dioxide (CO₂)-neutral cities, as these calculations focus mainly on climate change mitigation measures to reduce CO₂ emissions.

For example, changes in urban structure for new mobility patterns or the promotion of low-carbon lifestyles can have a positive impact on health by reducing environmental stressors such as heat stress. At the same time, urban planners and health authorities are trying to develop climate adaptation measures to minimise health risks for the urban population. However, a sustainable development of cities requires a combination of climate protection and climate adaptation.

The research project CoSynHealth (Conflicts and Synergies between carbon-neutral and healthy City Scenarios) aims to close the gaps between research on climate protection and climate adaptation. The young scientists are investigating how conflicts of objectives between scenarios for CO2 neutrality versus scenarios for healthy cities can be resolved, for example in the area of mobility: compact cities encourage movement, reduce commuting times and energy consumption for public transport; at the same time, however, compact cities also lead to more development of heat islands.

Climate services are developed together with the relevant stakeholders in order to establish the services in an innovative participatory process. They will help to generate sustainable scenarios for cities that focus on the health of the population. The climate services are based on an urban systems approach. This takes into account complex interactions between urban health, urban climate, built environment, urban society, urban residents and assumed climatic and demographic changes. In particular, results from a high-resolution urban climate model (Palm4U) and agent-based modelling are integrated to determine future exposure to heat stress. The potential impact of climate mitigation and adaptation measures on health will be assessed at the neighbourhood level.
The BMBF is funding CoSynHealth with around 1.66 million euros from 2023 to 2028.
