In the crowded courtyards of southern China's urban core, a research team has entrusted an evolutionary algorithm with a question that has long tested human judgment: how to make a small patch of green simultaneously beautiful, affordable, and climatically useful. By running thousands of simulated generations of plant selection and spatial arrangement, the NSGA-II algorithm found configurations that outpaced experienced designers on all three measures at once. The result is not merely a technical achievement but a quiet provocation — suggesting that in the geometry of constrained spaces, intel

China strengthens its technological soft power and climate leadership narrative by demonstrating AI-driven solutions for carbon neutrality goals. This positions Chinese urban planning expertise as exportable technology to developing nations, potentially increasing influence in Belt and Road Initiative contexts. Contrasts with Western approaches to urban sustainability.
Similar to China's earlier positioning of high-speed rail technology as a development model export; using domestic policy achievements (dual carbon strategy) to establish technological leadership and international influence in green infrastructure.

Homeowners and property developers can achieve better environmental outcomes (carbon sequestration, aesthetics) at modest cost premiums (13.8%), making sustainable urban greening more economically accessible and attractive for residential and commercial properties.
Governments may integrate this optimization framework into building codes and urban planning regulations, particularly in high-density areas. Could support carbon pricing mechanisms, green building certifications, and incentivize decentralized greening strategies. May influence landscape design standards and environmental impact assessments for urban development projects.
