Zero-emission zones is an academic concept and urban policy instrument designating specific geographical areas where vehicular or other activities generating tailpipe emissions are restricted, typically permitting only zero-emission modalities. This concept is investigated across disciplines such as urban planning, environmental science, and transportation engineering to analyze its design, implementation strategies, enforcement, and multifaceted impacts. Key characteristics include precisely defined spatial boundaries, strict regulatory criteria demanding zero direct emissions from permitted activities or vehicles, and associated infrastructure considerations. The significance of zero-emission zones lies in their potential to serve as a targeted mechanism for improving urban air quality, mitigating greenhouse gas emissions, enhancing public health outcomes, and accelerating the transition towards sustainable urban mobility systems.
