Introduction Climate change demands urgent action, and low-carbon urban governance has become crucial for sustainable development. China introduced the Low-Carbon City Pilot (LCCP) policy to reduce emissions promote green growth. This study evaluates how LCCP affects high-quality development (HQD), providing insights policymakers. Methods We measured HQD using entropy weight method employed difference-in-differences (DID) approach with 2000-2021 panel data from 351 Chinese cities, treating as a quasi-natural experiment. Analyses included baseline tests, robustness mechanism heterogeneity analysis. Results The findings indicate that significantly enhances HQD, thereby supporting Porter Hypothesis within context of China’s environmental economic policies. Robustness including parallel trend test, propensity score matching-DID, expanded sample analysis substituted explained variable, confirm reliability these results. Mechanism reveals improvements in are driven by technological innovation, industrial upgrading, infrastructure development, energy system transformation. Furthermore, shows policy’s impact is more pronounced general cities Han provinces. Discussion These results demonstrate functions “gift” enhancing offering valuable refining policies actionable lessons other countries pursuing ecological environment well-being

With the acceleration of urbanization, accessibility and equity urban green spaces have become crucial issues in planning public health. In context 15-min living circle, whether residents can conveniently reach parks within a walkable or bikeable time frame directly impacts their quality life social well-being. Traditional park evaluation methods, such as G2SFCA, effectively measure but fail to fully account for diversity travel modes impact regional disparities on equity. This study employs TB-G2SFCA method, integrating concept analyze Dianchi Lake ring area Kunming under different modes. The findings reveal significant walking cycling, particularly suburban communities distant from city center, where many areas cannot 15 min. Although improves driving transit modes, resources remain concentrated well-connected areas, leaving peripheral regions with insufficient access. Compared traditional G2SFCA approach more accurately reflects spatial differences across suggests that future should optimize resource allocation, improve transportation networks, enhance areas—especially cycling—to achieve equitable sustainable distribution spaces.

Son dönemlerde iklim değişikliği ve afetlerin yaşanma sıklığının artmasına bağlı olarak kentsel alanlarda yeşil alanların kullanımı, yeterliliği erişilebilirliği akademik politik söylemde sıkça vurgulanmaktadır. Kentlerin değişen koşullarına adaptasyonu sürdürülebilir kentleşme için bu alanlara erişilebilirlik önemlidir. Bu makalede Tarsus’ta bulunan 45 mahallenin analiz edilmiştir. Yeşil analizde Tampon Bölge (buffer) Analiz Hizmet Alanı (Service area) analizi kullanılmıştır. tampon bölge analizinde her bir alanın yarıçapı 200 m, 400 m 600 hesaplanmıştır. Analizinde ise konut alanlarından yürüme süresi 5, 10 15 dakika kişi başına düşen alan miktarı 4.55 m2’dir. oran Türkiye yönetmeliklerinde belirtilen m2 oldukça altındadır. Kentsel alanda 0-5 süresinde ulaşılabilen toplam 26.891.780 m2, 5 ile arasında 70.192.749 ila mesafesinde olan 121.515.881 Sonuç kent merkezinde erişilebilir konumda olduğu ancak çeperinde erişebilirliğin sınırlı tespit kapsamda mevcut alanlar nitelik nicelik açısından yetersizdir. içinde eşit dağılmadığı belirlenmiştir.
