本研究は、2025年から2050年までの新規都市開発における都市計画が、交通と建築部門のGHG排出量をBAU比14%削減できることを示した。コンパクトな設計、混合利用、低炭素交通インフラが効果的であり、特にアジア・アフリカの成長都市での重要性を強調している。
English
This study develops scenarios to quantify the mitigation potential of urban planning in new settlements from 2025 to 2050, finding a 14% reduction in GHG emissions compared to business-as-usual. Contributions come equally from transport and building sectors, with compact design, mixed-use, and low-carbon infrastructure as key levers. The analysis highlights the importance of rapidly growing cities in Asia and Africa.

In the global GX context
This study provides robust quantitative evidence for urban planning as a climate mitigation strategy, directly relevant to global urban climate initiatives such as C40 and ICLEI. It underscores the role of land markets and social cost internalization, offering a framework for cities worldwide.
👥 読者別の含意
🔬研究者:Provides a scenario modeling framework that can be adapted for city-level GHG reduction planning and integrated with other mitigation strategies.
🏢実務担当者:Offers evidence that compact, mixed-use urban design paired with low-carbon transport infrastructure yields measurable emissions reductions, useful for city planners and developers.
🏛政策担当者:Demonstrates that urban planning is a cost-effective climate tool that also benefits public finances, supporting policy integration in national and local climate plans.
📄 Abstract（原文）
Abstract Urban planning (UP) is a key lever for municipal climate mitigation, relevant for both reducing greenhouse gas (GHG) emissions in urban transport and within the building sector. However, it is unclear how large the municipal mitigation potential of UP is. Here, we develop scenarios that explicitly consider the contribution of new settlements between 2025 and 2050 for both transport—by reducing the distance travelled by cars and by modal shift-, and buildings—by supporting more compact building forms that reduce energy use and construction demand. We find that UP—a focus on compact design, mixed use, and low-carbon transport infrastructure—can reduce future GHG emissions by 14% compared to business as usual, with about equal contributions from transport and building sectors, notably including construction. Compact UP benefits the public purse, but requires land markets that internalize social costs. Our analysis highlights the importance of developing and rapidly growing cities in Asia and Africa in supporting UP-related mitigation efforts.
