Urban decision-makers must determine optimal city sizes to achieve net-zero emissions. However, previous studies have mainly focused on average relationships between city size and carbon emissions, overlooking non-linear dynamics. This study used urban scaling laws to investigate relationships between city size and carbon emissions from population and land perspective across 294 Chinese cities. Results showed a sub-linear relationship between urban population size (UPS) and carbon emissions and a super-linear relationship between urban land size (ULS) and carbon emissions. Regionally, cities in central regions demonstrated higher carbon emission performance than those in western and eastern regions. The land perspective indicated lower carbon emission performance compared to the population perspective. Both perspectives revealed non-linear relationships between city size and urban scaling exponent for carbon emissions, characterized by multiple minima. Multiple city sizes can achieve optimal carbon emissions; however, only one ULS is ideal for a specific city size to ensure environmental sustainability. This study provides valuable policy insights for decision-makers in formulating reasonable low-carbon strategies.</div></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"177 ","pages":"Article 103571"},"PeriodicalIF":4.0,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143488239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Key findings include: (1) downtown Beijing exhibits substantial solar energy potential, with seasonal and spatial variations. Solar energy levels are highest on east-west oriented streets during summer, reaching up to 15.0 MJ/m²/day, while winter levels can drop to as low as 6.0 MJ/m²/day in densely built areas; (2) photovoltaic-powered buses can generate up to 100 kWh per day, enabling annual travel of 88,500 km under clear skies and 64,300 km under cloudy conditions, while reducing carbon emissions by 88.4 tons and 64.3 tons, respectively; (3) integrating photovoltaic systems into public transportation offers significant economic and environmental benefits, enhancing energy security and promoting sustainability.

This study explores whether and how cultivated land restoration can enhance grain production while minimizing regulating services loss. The Sanjianghui area in Hangzhou city, China, was selected as a case study to examine effects of different restoration scenarios, on provisioning and regulating services and their trade-offs. The findings suggested that the types, quantity and location of restored areas significantly influenced ecosystem services. Across eight scenarios, both trade-offs and synergies between provisioning and regulating services were observed as the restoration area expanded. The optimal scenario based on trade-offs and synergies was scenario 2035-Ⅱ, which recorded the highest synergistic intensity at 26.6%. Under this scenario, grain production increased by 5.32%, and regulating services improved by 0.11% compared to the 2020 baseline.

Third, we argue that the nature of complex, pressing problems requires convergence research to be politically engaged and accountable to the multiple communities affected.

Indeed, many companies have been held to account for their negative impact on the environment rather than being appreciated for their technological and financial performance. It therefore stands to reason that companies are interested in proving to society that they are also concerned about environmental wellbeing, and to do so they are resorting to eco-reporting.&lt;/div&gt;&lt;div&gt;This disclosure involves the qualitative and quantitative data that measure, calculate, and estimate the environmental impact of a company's operations. At the same time, stakeholders are increasingly lobbying companies to make major efforts in eco-responsibility in the form of environmental reports, disclosing aspects related to the organisation's public image and its eco-related activities and aspirations.&lt;/div&gt;&lt;div&gt;This research analyses environmental reporting practices involving companies in the food &amp; beverage sector across different countries and continents to identify possible differences and similarities between them. This provides us with a greater and more robust understanding of organisations and the environment in diverse institutional settings. The target population consists of companies in developed economies such as the USA, Australia, Canada, and the EU, and developing ones such as China, India, Brazil, and Mexico. To facilitate the interpretation of the results, the countries have been grouped by continents: Europe, Africa, Asia, America, and Oceania. Food &amp; beverage is the sector of choice because it provides an essential service for people's sustenance and has attracted the attention of scholars in the fields of the environment and sustainability. Moreover, prior evidence shows that the food &amp; beverage sector depends largely on natural resources, with a far-reaching impact on the environment. The methodology used involves multivariate techniques that enable us to analyse the joint behaviour of several variables and provide an insight into how the different environmental indicators perform, as they can be identified by countries and continents.&lt;/div&gt;&lt;div&gt;Beginning with the 19 environmental variables belonging to the dimension of resource use, the results obtained by applying logistic biplot reveal a significant increase over the entire period in question, with changes in priorities across these variables.

As regards the dimension of emissions, the trend has been similar to the one involving resource use, with significant growth over time and changes in the priorities of businesses in this sector, with their preferences being policy emissions (PE), waste reduction initiatives (WRI), and target emissions (TE).
