Which approach does C40 support regarding urban infrastructure?

C40 supports prioritizing green infrastructure solutions as a critical approach to addressing urban challenges and promoting sustainable city development. This focus aligns with the organization's overall mission to tackle climate change and drive urban resilience. Green infrastructure involves integrating nature into urban spaces through parks, green roofs, urban forests, and sustainable water management systems.

Such strategies not only help mitigate the heat island effect and improve air quality but also enhance the overall quality of life for city residents by providing recreational spaces and promoting biodiversity. Additionally, green infrastructure often leads to more efficient resource management, cost savings in the long run, and a reduction in carbon emissions.

The other approaches presented do not align with C40's commitment to sustainability and climate action. For example, building highways typically encourages car dependency and increased emissions, while expanding suburban developments can lead to urban sprawl, which is generally not viewed as sustainable. Reducing public spaces for economic gain runs counter to the goals of fostering inclusive, accessible, and resilient urban environments. Thus, prioritizing green infrastructure is firmly rooted in C40's vision for the future of cities.
