Summary: In this study, a comprehensive life cycle assessment (LCA) model was established to evaluate the environmental impacts, abiotic depletion, and comprehensive performance of pruned fruit tree branches (PFTB)-based biomass energy in China. It was found that the comprehensive performance of PFTB-based biomass energy was superior to coal-fired power generation. The total solid waste and raw material consumption rate were identified as the most sensitive factors affecting the comprehensive performance.

Summary: The construction of megaprojects is crucial for the development and economic growth of any country, especially in developing nations. However, megaprojects in Kuwait face restrictions that hinder their execution and lead to significant delays. This study aims to develop a complexity measurement model for megaprojects in Kuwait, focusing on the New Kuwait University campus as a case study. The study applies a hybrid fuzzy analytic hierarchy process (FAHP) method and compares it with the conventional AHP method. The findings reveal the complexity factors and their varying levels in different dimensions, emphasizing the importance of assessing and understanding these complexities for the successful completion of megaprojects.

Summary: This study proposes a safety risk assessment method for drug production based on Grey-Analytic Network Process (G-ANP) to strengthen correlation analysis on risk factors and reduce the influence of fuzzy judgments. The method constructs an index system for evaluating drug production safety risk, determines the influence weight of each risk index using Analytic Network Process, utilizes grey statistical theory to determine the grey number of each risk index, and obtains the risk level of drug production. The empirical study supports the feasibility and practicability of using G-ANP method for drug production safety risk evaluation.

Summary: When a regional government considers investing funds for sustainable development, it should take into account the real needs of the population and the achievement of the Sustainable Development Goals (SDGs). This paper aims to answer how to guide public investment policies at the local level to better meet the SDGs. It uses a multi-criteria decision-making process to classify and prioritize investment areas based on SDG-derived criteria. The complexity of the problem arises from difficulties in stakeholder engagement and interrelationships between elements of the decision problem, which are addressed using the Analytical Network Process method combined with DEMATEL. The case study of fund distribution in Colombia's Meta Region involves 48 stakeholders identifying needs and six experts prioritizing them.

A model integrating demand response modelling, reserve requirements, and hydrogen as an energy vector is used to analyze various scenarios. The results suggest that the Spanish decarbonization goals are based on optimistic assumptions, and energy storage will play a larger role than expected, with hydrogen storage necessary only at 100% penetration of renewable energies.

Summary: Municipal solid waste management is important for achieving sustainable development goals, but the application of multi-criteria decision-making (MCDM) in this field mainly focuses on selecting waste treatment technologies and facility locations, with little research on sustainable transport alternatives. This study evaluates different engine technologies for waste collection trucks under sustainability criteria in a Spanish city using the stratified best and worst method (SBWM). The results show that electric and diesel trucks are the best options, followed by compressed natural gas (CNG) and hybrid CNG-electric trucks, with hydrogen-powered trucks ranking last.

Summary: Hundreds of cities worldwide are aiming to achieve decarbonization or carbon neutrality by 2030, 2050, or earlier. This is particularly challenging for the dense, compact cities in the European Mediterranean region. To increase energy self-sufficiency, Mediterranean cities are looking to scale up rooftop PV production and utilize ground-mounted plants in their surroundings. This paper proposes an alternative approach of energy exchange between cities and their metropolitan areas, demonstrated through a case study of Valencia, Spain. The results show the potential of rooftop PV in significantly increasing the PV coverage rate and may inspire the development of innovative urban-metropolitan energy exchange models.

Summary: This paper examines the impact of real-time pricing and load automation on residential distribution systems. The study finds that implementing real-time pricing can result in an aggregate welfare gain of 39 USD per customer and year. However, it also notes that RTP and load automation may significantly increase peak system load. Introducing a market-based demand management system can further enhance welfare gains and reduce grid investment.

Summary: Household solid fuel use is detrimental to health and the environment. The Indian government's PMUY subsidy has successfully promoted the adoption of LPG by millions of households. However, there is limited understanding of the decision-making process to reduce solid fuel use after transitioning to cleaner fuels. This study found that factors such as household wealth, social status, education level, and the prevalence of LPG use in the village are positively associated with LPG consumption and the discontinuation of solid fuel use. On the other hand, factors such as distance to LPG refill delivery, household size, and the PMUY subsidy are negatively associated with the share of LPG use.

Summary: Economic costs are a major political obstacle to investing in climate change mitigation and adaptation measures. The method of financing plays a crucial role in determining public opposition to government green investments, with debt financing being less opposed than broad-based taxes. This study suggests that credit market tools, such as green bonds and debt for climate swaps, can be politically efficient in increasing support for green financing. Carbon taxes and wealth taxes are found to be the most preferred options.

Summary: This paper investigates China's energy trade stability using a survival analysis approach. It finds that the energy trade linkages between China and 153 other countries are complex and unstable, with short periods of trade with many countries. Geopolitically risky regions, such as the Middle East and Africa, have the lowest trade stability. Climate risks have significant effects on energy trade stability. The paper proposes several policy options to improve energy trade stability in China, with special attention to increasing global climate risks.

Summary: This study estimates the willingness to pay of Indian urban consumers for a continuous supply of electricity using contingent valuation method. The findings show that the amount consumers are willing to pay depends on the duration of power outages, with households preferring shorter outages. Income and environmental attitude also positively influence higher willingness to pay. These insights can inform policymakers in designing more reliable and customer-centric energy generation and distribution models.

This study investigates the impact of REC purchases on stock return and volume in Taiwan between 2017 and 2021. The findings suggest that REC purchases have a positive effect on stock returns of manufacturing firms but not service firms. The frequency of REC purchases is also an important factor in the relationship between REC purchase and firm value. Additionally, the study reveals that public attention to environmental pollution plays a crucial role in positive stock returns and volume, while ESG disclosure is negatively associated with returns and volume.

Building on political economy analysis and five case studies of independent producer projects from Ethiopia, it seeks to understand the root causes of the protracted delays and limited extent of procurement by independent producers. The key contestations lie in managing long term contracts, risk, uncertainty and in developing the institutional and human capacity to transition.
