JAKARTA – 'Green city' initiatives championed across various parts of the world, including the installation of green roofs, extensive tree planting, and vegetated facades, are now facing sharp criticism from urban planners and environmental experts. Many view these measures as more akin to symbolic politics than effective solutions for climate change mitigation, especially in addressing the increasingly alarming problem of urban heat in 2026.
The main critique targets an approach deemed too superficial. 'Greening' programs often fail to address the root causes of urbanization and its climatic impacts. Urban planners suggest that an excessive focus on aesthetic green elements distracts from deeper structural challenges in climate adaptation.
They argue that the implementation of trees and green roofs, while visually appealing, often cannot provide a significant impact on overall urban temperature reduction. The localized cooling effects produced tend to be limited and not commensurate with the rate of global temperature increase and heat emissions from urban activities.
Intense discussions are now developing regarding the necessity for fundamental reforms in urban planning. Instead of merely adding green elements, a more comprehensive approach is needed to make cities truly resilient to heat.
An urban architecture expert from Gadjah Mada University, Dr. Surya Atmaja, highlighted, “Many green city projects focus on what looks good in brochures, not on what functions optimally in the field. We need to talk about smart density and how to leverage existing building structures.” This statement emphasizes that true solutions lie in space efficiency and infrastructure.
Well-planned urban density can actually contribute to energy efficiency and reduce carbon footprint. Denser buildings can minimize the need for long-distance travel, support public transportation, and reduce surface exposure to solar radiation if strategically designed.
Furthermore, experts underscore the importance of considering the building materials used. Concrete and asphalt have a high heat storage capacity. Replacing or coating these materials with more reflective or permeable ones can drastically reduce the urban heat island effect.
Another often-overlooked aspect is 'beauty' in urban planning. Cities designed with harmonious aesthetics and functionality tend to be more appreciated and cared for by their inhabitants. This beauty is not merely about ornamentation, but also efficient spatial arrangement, accessibility, and quality of life.
European cities, such as Berlin and Vienna, are beginning to re-explore urban development concepts that integrate aspects of density, energy efficiency, and captivating design. They strive to create livable environments, not just symbolically 'green' ones.
This debate marks a paradigm shift in urban climate adaptation. The challenge ahead is how to shift focus from symbolic politics to implementable strategies based on science and data, in order to create truly sustainable and livable cities in the future.
Governments and stakeholders worldwide are expected to revise urban development policies. Public education on the essence of effective climate adaptation is also crucial for communities to support more substantial and lasting efforts.
Thus, urban transformation is not just about adding more plants, but about designing integrated, efficient, and aesthetic urban ecosystems. Only with this holistic approach can cities genuinely and sustainably address the challenges of climate change.
