GCC諸国は2050〜2060年のネットゼロを掲げるが、都市は猛暑・冷房・淡水化・車依存により世界有数の高炭素強度を持つ。本稿は部門別脱炭素では不十分とし、建物・都市形態・冷房・電力・水・交通・資材・廃棄物の相互依存を「ネットゼロ都市方程式」で整理する。三つの構造的パラドックスと四つの結合介入経路を示し、実装の鍵は技術より一貫した会計・経済的インセンティブ・制度調整にあると論じる。
English
GCC states pledge net-zero by 2050-2060, yet their cities remain among the world's most carbon-intensive due to extreme heat, cooling, desalination and car-dependent form. This Perspective argues sectoral decarbonisation is insufficient because buildings, urban form, cooling, power, water, transport and materials are interdependent. A simplified Net Zero City Equation frames three structural paradoxes and four coupled intervention pathways, concluding that consistent accounting, incentives and institutional coordination matter more than technology availability.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の都市脱炭素・SSBJ開示を考える上で、冷房・水・電力の相互依存を統合会計で捉える視点は、都市規模のScope把握や自治体・企業の統合報告に示唆を与える。
In the global GX context
Speaks to global disclosure scholarship by highlighting fragmented accounting and governance as a barrier to net-zero cities, resonating with ISSB/CSRD efforts to capture urban-scale and cross-sector interdependencies beyond corporate boundaries.

📄 Abstract(原文)
Gulf Cooperation Council (GCC) states have pledged to achieve net-zero emissions between 2050 and 2060, yet their cities remain among the world’s most carbon-intensive, shaped by extreme heat, near-continuous cooling, desalinated water, car-dependent urban form and hydrocarbon-financed development. This Perspective argues that conventional sectoral decarbonisation strategies, while necessary, are insufficient because building performance, urban morphology, cooling demand, electricity generation, water infrastructure, transport, construction materials and waste management are interdependent. A simplified Net Zero City Equation, adapted from established whole-life carbon accounting principles, provides a conceptual framework for examining these interdependencies. Three structural paradoxes (hydrocarbon dependence versus decarbonisation, cooling demand versus energy and water decarbonisation, and net-zero ambition versus fragmented accounting and governance) help explain the challenges of transition. Four coupled intervention pathways identify opportunities for coordinated action: climate-responsive urban form and buildings; integrated energy, cooling and water systems; low-carbon mobility and circular material flows; and coordinated governance, measurement and finance. Implementation depends less on the availability of technology than on consistent accounting, economic incentives and institutional coordination. This approach is relevant to other hot-arid regions, provided it is adapted to local climatic, urban and institutional conditions.
