However, urban decoupling has gradually improved over time, with cities experiencing strong or weak decoupling reaching 52.8 %. (3) For cities like CD cities, there are significant urban-rural inequalities in per capita income, but smaller differences in residential buildings' carbon emissions.

It covers the challenges faced by over a million displaced Syrians in 1293 refugee camps, focusing on the scarcity of fuels for heating and cooking and the consequent health risks due to indoor air pollution. A mixed methods approach was utilized, combining questionnaires from a sample of 439 participants, 75 % of them displaced, indoor air quality monitoring across 14 dwellings and in-depth interviews from 20 homes. The houses monitored were a mixture of apartments, tents, stone cement and containers; with fuel types ranging from diesel, coal and LPG to wood, olive husk and nut shells. The analysis reveals a significant correlation between the use of solid fuels in households and lack of ventilation with the increase in indoor air pollution, with maximum PM<sub>2.5</sub> concentrations above 114 μg/m<sup>3</sup> and maximum TVOC concentrations above 1200 ppb, well above recommended threshold values. This is supported by 36 % of participants reporting health issues, highlighting substantial health risks associated with these practices. It also demonstrates the influence of dwelling typology and ventilation in thermal comfort and indoor air pollution, with containers performing the worst, reaching maximum CO<sub>2</sub> levels above 5000 ppb.

Understanding the current energy landscape requires assessing past achievements, leveraging resources, embracing technological advancements, and implementing effective policies. A thorough analysis is vital to identify gaps in achieving our Nationally Determined Contributions, ultimately facilitating net-zero goals. The urgency to mitigate emissions, heightened by climate-induced events and the need for renewable energy integration, calls for a reconsideration of net-zero timelines. Delayed action poses significant risks to ecosystems and economies globally. This paper explores how different pathways to net-zero emissions for power sector by 2050 & 2070 target years impact the future electricity mix, costs, generation profiles, and emission trajectories. We employ the energyRt optimization model, a bottom-up framework capturing regional, seasonal, and diurnal variations of renewable energy sources for thirty years, from 2020 to 2050. Preliminary analysis suggests current renewable resource estimations might not be sufficient for a 2050 net-zero goal. To meet the projected 6273 TWh demand by 2050, installed capacity would range from 2042 GW to 3100 GW. The base case emission trajectory reaches 2.4 GtCO<sub>2</sub>/year in 2050 with a grid emission factor of 0.369 tCO<sub>2</sub>/MWh.

This paper is an effort to unpack this complexity by applying the principles of consultation and consent. Specifically, the paper asks three questions: first, what is the nature of engagement and consultation posited in the policy and regulatory landscape currently driving India's renewable energy development process? Second, how does it compare with key international norms and commitments? Third, what recommendations can be made to strengthen consultation and consent principles in India's renewable energy policy and practice?

However, the lack of comprehensive studies on monetizing and accounting for the overall direct and indirect cost benefits of biogas plants often hinders benefit communication to people and the preparation of appropriate policy measures for net zero energy transition in many developing countries. To address these issues, this study conducted a nationwide household survey comprising 1392 primary samples in Nepal, using a benefit-accounting framework based on different biogas sizes in three ecological belts (mountains, hills, and Terai). The results revealed that an average household biogas plant replaces 4.5 tons of biomass annually. Direct annual economic savings by a one cubic meter biogas plant in the Terai region were found to be NRs 9000 (USD 69.23). In contrast, in the hilly and mountainous regions, the benefits increased by NRs 2250 and NRs 4500 respectively. Annual displacement of fuel wood by the total household biogas plants installed in Nepal accounted for 1.8 million tons and saved 2.8 million tons equivalent CO<sub>2</sub> emission. Besides the direct benefits, many indirect and social benefits linked to crop productivity, timesaving for economic activities, improved health, and the environment were investigated. Accounting for integral benefits, biogas plants had significant (35 to 43 %) additional benefit contributions over direct savings, which are often neglected in accounting frameworks. Government subsidies have improved the feasibility of biogas plants. Outcomes beyond these accounting values only, this study provides several policy implications for the wider-scale promotion of household biogas in developing countries for meeting net zero energy transition goals.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"85 ","pages":"Article 101634"},"PeriodicalIF":4.4,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143102558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
