15分都市構想の下、都市緑地（UGS）の質的向上が地域内目的地への誘導と交通由来排出削減に寄与するかを評価するAccess-to-Abatement（A2A）フレームワークを開発。浮動集水域型アクセシビリティモデルと確率的目的地配分、グループ別選好、排出会計を統合した。15分圏内の質向上は域外依存とモビリティ排出のトレードオフを緩和し、郊外は局所的に、中心部は需要再配分を通じ市全体でより大きな削減をもたらすことを示した。
English
The authors develop an Access-to-Abatement (A2A) framework linking urban green space (UGS) quality, spatial accessibility, and travel-related emissions in the 15-minute city. It integrates floating-catchment accessibility modeling, probabilistic destination allocation, group-specific preferences, and emission accounting. Targeted UGS quality upgrades within the 15-minute catchment reallocate visits locally, improving accessibility while cutting travel emissions, with spatially uneven effects: peri-urban upgrades yield larger local reductions, central upgrades larger citywide ones.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではコンパクトシティ・立地適正化計画や都市緑地政策と親和的で、自治体の脱炭素まちづくり計画や都市計画における緑地配置の根拠づけに資する。企業開示への直接接続は弱いが、自治体GXやScope 3通勤・移動排出の議論に示唆を与える。
In the global GX context
Connects urban planning and land-use policy to transport-emission outcomes, relevant to city-level climate action plans and the growing treatment of commuting/mobility emissions in corporate and municipal inventories. Offers a transferable modeling approach for assessing co-benefits of green infrastructure investment under net-zero urban strategies.

📄 Abstract（原文）
Urban green-space (UGS) distribution and quality shape residents’ destination choices, travel behaviour and associated carbon emissions, yet few studies connect spatial accessibility and group-specific travel responses to carbon outcomes. We developed an integrated Access-to-Abatement (A2A) framework to assess whether targeted UGS quality upgrades can reduce reliance on destinations beyond the 15-minute catchment and lower travel-related emissions. A2A integrates a floating catchment area-based accessibility model with probabilistic destination allocation, UGS supply and quality, survey-informed group-specific preferences and travel-emission accounting. It quantifies accessibility gains and emission-reduction potential while tracing how local provision deficits and quality upgrades reallocate modelled visits. For communities below the citywide mean in either 15-minute accessibility or the mean quality of UGSs reachable within 15 min, we expanded destination sets using group- and mode-specific maximum acceptable travel times. This conditional expansion increased modelled accessibility but also reliance on motorised travel and associated emissions. Targeted upgrades within the 15-minute catchment mitigated this trade-off by reallocating modelled visits towards local UGSs, thereby improving 15-minute accessibility and reducing travel-related emissions. The emission-reduction effects were spatially uneven: peri -urban upgrades produced the largest local reductions, whereas central upgrades produced larger citywide reductions through demand reallocation. Abatement also followed a distance-dependent pattern, with the strongest reductions near upgraded UGSs, a rebound at intermediate distances and attenuation farther away. The framework identifies where quality upgrades can improve 15-minute accessibility and reduce travel emissions, supporting site-specific interventions based on UGS’s baseline deficiencies.
