Summary: Artificial walking survey, ground penetrating radar (GPR) and falling weight deflectometer (FWD) were used to test the actual condition of the highway pavement in reconstruction and expansion project for better maintenance decision-making. A decision-making system with four evaluation indexes was constructed, and the corresponding thresholds for different conditions were determined. The system effectively determined maintenance plans and resulted in cost savings and improved structural reinforcement ability.

Summary: This paper investigates the decision-making process of building refurbishment considering whole-of-life carbon reduction using three real-life case studies. The study reveals important findings on factors such as the effective adoption of building rating systems, the required carbon reduction targets, the importance of a dedicated financial budget, the need for adaptable refurbishment designs and long-term strategies, holistic design reports, early contractor involvement, government funding and incentives, and the availability of supply chains and data.

Summary: Efforts to utilize waste materials resourcefully in urban and industrial production systems have gained attention, leading to the development of carbon-reducing partition wall blocks through the substitution of Ordinary Portland cement with waste materials and supplementary cementitious materials. These blocks can significantly reduce carbon emissions, save landfill space and costs associated with disposal.

Summary: This paper investigates the impacts of sport emissions on climate and identifies knowledge gaps. The research focuses on carbon emissions and their measurement, emissions control and decarbonization, carbon sinks and offsets, and behavior change in sports. The study highlights the need for more research in grassroots and women's sports, activities in Africa and South America, cricket, tennis, and volleyball. Other knowledge gaps include carbon accounting tools for smaller sports clubs and active participants, the co-benefits and tradeoffs between mitigation and adaptation efforts in sports, geopolitical influence, and the potential for climate change litigation.

Summary: Organizations are interested in Life Cycle Assessment to understand trade-offs in producing products. However, there is little research on its effectiveness, limitations, or drawbacks in decision-making. The universalism of Life Cycle Assessment is affected by organizational politics and bias, and recent trends are creating additional problems in decision-making.

Summary: The environmental impacts of marine microalgae cultivation and harvesting from an Indian context were evaluated in this study. It was found that the algal-based technology could reduce emissions by 1.28 kg CO2 eq./kg algae produced. The source of electricity was identified as the main contributor to the marine aquatic ecotoxicity potential (MAETP). Replacing a higher percentage of Indian mixed grid electricity with solar-based electricity resulted in greater CO2 mitigation.

Summary: A multi-objective maintenance decision-making model called PM-GDE3 is proposed, which integrates pavement condition indices and the GDE3 method. The model considers economic, sustainability, and environmental dimensions to increase pavement management flexibility. Compared to the traditional PAVER model, the results show that the PM-GDE3 model achieves maintenance strategies with lower costs and environmental impact, making it a feasible solution.

Summary: This study investigates the carbon dioxide emissions of high-polymer grouting repair technology in the life cycle assessment of maintenance work on semi-rigid asphalt pavement. The results show a substantial reduction in carbon dioxide emissions for highway maintenance projects employing high-polymer grouting repair technology. The primary contribution to carbon dioxide reduction is observed during the construction phase and in terms of alleviating traffic delays. Furthermore, the study establishes an indirect relationship between the carbon dioxide emissions of high-polymer grouting materials and their strength.

Summary: This paper proposes an outdoor environment evaluation tool based on the multi-criteria decision-making method for existing neighbourhoods in China. Evaluation indicators of the acoustic, luminous, and thermal environments and air quality were chosen and classified. The weights of each indicator were determined through opinions from residents and experts. The results show that the outdoor environments of the evaluated neighbourhoods are inadequate in terms of acoustic and luminous environments, but there is potential for improvement in the thermal environment and air quality. Corresponding renovation and upgrading suggestions were put forward.

Summary: The study suggests that fully softened strength criteria are not suitable for assessing shallow first-time failures due to seasonal stress cycles. Slopes between fully softened and residual friction angle may be at risk of failure in the future. Implementing residual strength parameters may lead to overly conservative solutions considering the required design life of geotechnical assets.
