Published: Jan. 11, 2025

Climate change is a major global issue because transportation source of pollutants and greenhouse gases that affect human health air quality. However, to effectively prioritize fund mitigating actions, decision-makers lack scientific rigor diagnoses with sufficient spatial resolution. Based on the Origin-Destination Matrix (ODM), this study suggests methodology measure identify mobility emissions (CO2, Nox, PM) at neighborhood level high Testing was performed in Valencia, Spain. Even though many studies calculate carbon footprint, few make use precise geographic information openly accessible data, they frequently concentrate entire cities rather than smaller areas. To determine all potential routes for each (OD) trip, process uses geostatistics estimate daily trip activity data (kilometers traveled). The COPERT calculator from European Union used analyze these total distance traveled per neighborhood. road infrastructure, determines which neighborhoods receive creates measures equitable environmental responsibility. It also identifies short trips might be replaced by cycling or walking, as well possible improvements public transportation.

Decoupling and peak prediction of industrial land carbon emissions in East China for developing countries’ prosperous regions

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Feb. 20, 2025

Urban energy consumption is mostly concentrated in industrial regions, and carbon emissions from land use have significantly increased as a result of fast urbanization industrialization. In the battle against climate change, affluent regions developing countries are increasingly being used models for reducing emissions. Therefore, order to accomplish global sustainable development, it crucial understand how decoupled wealthy areas rising nations. This study investigates decoupling effects factors influencing them six East Chinese provinces one city between 2005 2020 using Tapio model LMDI decomposition approach. At same time, 2021 2035 were predicted BP neural network combined with scenario analysis. The findings indicate that: (1) From 29.921 million tons 40.2843 2020, China area nearly doubled. Of these, Shandong Jiangsu emit more than half region's total around China. (2) effect analysis shows trajectory's phased characteristics, degree gradually increasing weak (2006-2012) strong (2013-2018) finally negative (2019-2020). (3) primary causes rise region scale per capita economic output use. (4) overall peak time roughly distributed 2028 2032.

Quantifying the Provincial Carbon Emissions of China Embodied in Trade: The Perspective of Land Use

Land, Journal Year: 2025, Volume and Issue: 14(4), P. 753 - 753

Published: April 1, 2025

Land use supports production and living activities provides ecosystem services for people. With the flow of capital, goods, among regions, trade leads to transfer carbon emissions from importing regions exporting this is telecoupled with land systems in different regions. Although significant progress has been made quantifying embodied induced by interprovincial international trade, telecoupling relationship between not sufficiently investigated. Here we followed theoretical framework used multi-region input–output (MRIO) model examine spatial pattern China due trade. The results show that patterns end consumption are based on type. provinces rich energy resources favorable conditions such as Inner Mongolia, Xinjiang, Heilongjiang undertake agricultural industrial other provinces. In contrast, large economies but scarce Zhejiang Guangdong export larger portions their Across China, developed generally exported more than they developing was prominent eastern western were transferred southern northern areas. Our research reveals types, these findings could provide detailed information policy-making processes achieve fair sustainable use.

Assessments of the ecosystem service value (ESV) and social cost carbon (SCC) inform national government management decisions in areas human well-being climate change mitigation adaptation, respectively. Studying correlation between two provides a theoretical basis for low-carbon high-quality regional development, achieving economic decarbonization, improving well-being. In this study, we take Zhoushan Archipelago as case consider ESV SCC during period 2010–2020, analyze their spatial development characteristics, time space. The findings indicate that, with only 1.5% change, overall fell 2010 2020. Conversely, there was 1604.01 × 104 t increase net emissions quick 2452% SCC. During study period, substantial positive association found Archipelago, according to global analysis variables. It passed test p-value. This presents new potential way solve environmental difficulties caused by providing mechanism quantitatively assessing environment from perspective monetary worth. order improve ecological security pattern ease burden emissions, it is vital make use advantages, maintain forests, develop blue-carbon resources such mudflats. good idea cooperate regionally nearby metropolitan agglomerations. study’s are crucial advancing sustainable planning both theoretically practically.
