A study by ISGlobal reveals a complex dilemma between public health and climate sustainability in European cities. While compact cities achieve a lower per capita carbon footprint thanks to energy efficiency and active mobility, they suffer from worse health indicators due to high levels of pollution, the urban heat island effect, and a lack of green spaces. Conversely, green and dispersed cities offer a healthier environment and lower mortality rates, but generate higher CO2 emissions because they rely more heavily on motorized transport for long-distance travel. The research suggests that the compact city model has the potential to become the sustainable future, but it requires urgent transformation to mitigate its negative impacts on health. The authors propose implementing specific strategies, such as creating superblocks, reducing motorized traffic, and integrating green infrastructure, such as trees and green roofs. The goal is to balance high density with environmental improvements, leveraging the advantages of proximity without sacrificing air quality and urban well-being. This research is crucial for understanding greenwashing, as it dismantles the simplistic narrative that high urban density is inherently more "ecological" or sustainable. It shows that true sustainability must encompass both emission reductions and the protection of public health, exposing how cities can exploit labels of "efficiency" while ignoring the serious health costs associated with local pollution. It compels us to evaluate the true, comprehensive impacts, avoiding selective data that mask local environmental degradation.
