The first is the reduction of atmospheric greenhouse gas emissions, especially carbon dioxide. The second is the maintenance of biodiversity. Current carbon financing and environmental stewardship mechanisms underwhelm, often diluting intended positive effects. Most existing carbon credits do not have protection after 40 years, placing projects substantially beneath the C02 radiative forcing cycle. This paper presents the ‘Balance’ approach to sustainable development, including contractual principles ensuring C02 reduction, biodiversity enhancement and financial accountability. We describe two novel measures: a carbon calculator for commercial entities, and a new metric, the Balance Unit, combining biodiversity creation with carbon credits. A case study, spanning over 20 years at the Forest of Marston Vale, is then presented. It finds an increase in tree cover, CO2 sequestration, reduction in agricultural GHG emissions, sulphur dioxide and particulate matter absorption, and annual local economic benefits totalling £UK12.83 million. Expository detail regarding the ‘Planting Principles’ practised at Marston Vale is also provided. We argue that the Balance methodology, especially the Balance Unit, enables greater measurement reliability and long-term efficacy for maintaining biodiversity and reducing GHG emissions than current carbon financing approaches.","PeriodicalId":14406,"journal":{"name":"International Journal of Sustainable Energy","volume":"10 4","pages":"1472 - 1496"},"PeriodicalIF":3.1,"publicationDate":"2023-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138971818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ambient digesters have been widely used because of their ease of installation, low cost, and low energy input. However, to improve biogas production sustainably, there is a need to consider reactor heating using renewable energy such as solar. This study sought to apply psychrophilic and mesophilic biodigester temperatures for FW treatment. For ambient digestion, a complete-mix flexible biodigester, named STH-1000A, covered in a greenhouse structure was operated between 24 and 32 °C. A prototype complete-mix tank biodigester, named VUT-1000C, was designed and operated at mesophilic conditions of 37 °C through solar geyser heating. VUT-1000C produced 1200 L of biogas per day while STH-1000A 150 L/day. VUT-1000C and STH-1000A generated up to 1.8 and 0.4 kWh of electricity, respectively. The power balance showed that VUT-1000C used 68% of its power production and STH-1000A consumed 398%. Digester heating using solar geyser is a novel and promising technique for achieving mesophilic condition leading to improved biogas production.","PeriodicalId":14406,"journal":{"name":"International Journal of Sustainable Energy","volume":"3 1","pages":"1569 - 1582"},"PeriodicalIF":3.1,"publicationDate":"2023-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139210227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Balancing environmental, social and economic interests has become complex at the regional level due to spatial trade-offs in a contested space. To investigate stakeholder willingness to compromise on a joint ranking on wind and solar energy sites, multi-criteria decision analysis (MCDA) planning support was explored. Using a two-part stakeholder survey, four groups were identified: ‘advocates’ who were satisfied with the site ranking (66%), ‘realists’ who were willing to compromise despite previous disagreement (13%), ‘dissenters’ not accepting (35%), and ‘dogmatists’ not engaging. Planning decisions and stakeholder engagement are underpinned by distinct attitudes towards the role of (democratic) planning and sustainable development. The use of trade-off analysis can ensure transparency and trace back stakeholder interests in making planning decisions. However, decision quality factors also need to be considered to ensure a thorough planning reflection.","PeriodicalId":14406,"journal":{"name":"International Journal of Sustainable Energy","volume":"22 1","pages":"1538 - 1568"},"PeriodicalIF":3.1,"publicationDate":"2023-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139231592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research introduces a transport model designed to project the growth of EVs within the 2-wheeler (2W) and 4-wheeler passenger (4W) segments, considering different policy scenarios. These scenarios are assessed for their impact on technology adoption, fossil fuel demand, power requirements, and CO2 emissions. Additionally, the study presents a demand model to forecast national electricity demand. The power model is also developed and linked with the transport and demand models to evaluate different fuel mix options for meeting the projected national power demand through 2050. The findings reveal that ambitious policy scenarios can drive EVs to constitute roughly 45% of all 2W and 4W vehicles on Indian roads by 2050, substantially increasing electricity demand to an estimated 295 TWh with a 40% reduction in CO2 emissions within the transport sector. Significantly, the soft linkage between these models underscores the potential for India to meet up to 90% of its national electricity demand through renewable sources like wind, solar, and hydropower. The research underscores the feasibility of transitioning towards a low-carbon energy system through renewable energy and EV integration.","PeriodicalId":14406,"journal":{"name":"International Journal of Sustainable Energy","volume":"176 1","pages":"1517 - 1537"},"PeriodicalIF":3.1,"publicationDate":"2023-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139231366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal is to accurately describe non-steady state heat transfer in buried pipelines. A high-precision model is established by considering assumptions, equations, boundary conditions, calculation domain, geometry, and grid number. Calculation time is reduced, and accuracy is improved, providing a foundation for optimizing the thermal insulation layer. ANSYS software is used to simulate and optimize the thermal insulation of the pipeline. Results show a maximum error range of 1.20% to 10.20% with consistent temperature trends, verifying the model’s accuracy. The heat-affected zone of the thermal bridge is evaluated and optimized, and preventive measures are proposed to reduce the impact of heat bridges in joint areas. The study also compares nodular cast iron pipes with conventional steel thermal pipes under the same conditions. It reveals that the economic thickness of the thermal insulation layer for nodular cast iron pipes increases from 31 mm to 39 mm due to the thermal bridge effect, which is significant.","PeriodicalId":14406,"journal":{"name":"International Journal of Sustainable Energy","volume":"35 3","pages":"1497 - 1516"},"PeriodicalIF":3.1,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139269520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a Panel Vector Autoregressive (PVAR) model and Granger Causality tests, the research probes the causality among these factors. Key findings show a notable causality from GDP, renewable energy, and trade openness to CO2 emissions. Specifically, lags in renewable energy consumption and trade openness significantly decrease CO2 emissions. Surprisingly, GDP's influence on CO2 emissions is found to be negligible, challenging the typical belief linking economic growth to environmental degradation. These insights hold great value for policymakers in environmental governance and climate finance. The data underscores the importance of promoting renewable energy and trade openness for effective CO2 reduction. The study advocates a sustainable environmental governance model, emphasizing strong legal structures and clarity in execution. Since GDP doesn't significantly impact CO2 emissions, there's potential to pivot towards sustainable economic growth models. The research offers a foundational empirical groundwork, suggesting that expanding future studies to include diverse variables might yield a more comprehensive understanding of the relationships in question.","PeriodicalId":14406,"journal":{"name":"International Journal of Sustainable Energy","volume":"29 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135876160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
