From building codes to mobility restrictions and new diplomatic roles within city governments, climate policy is increasingly being shaped at the local level through a widening range of legislative and institutional tools. Cities as varied as Sydney, Boston, New York, Paris, Miami, and dozens across Latin America are adopting targeted strategies that reflect their distinct environmental pressures and governance structures. These initiatives range from all-electric and net-zero construction requirements, to traffic-control measures designed to curb the social costs of private vehicle use, to emerging forms of urban diplomacy that coordinate responses to rising temperatures and biodiversity loss. Together, these approaches illustrate how territorial management is evolving in response to the accelerating climate crisis, and how local governments are experimenting with regulation and collaboration to confront challenges that are at once global and deeply place-specific.
