Summary: The study indicates that while installing PV systems reduces annual costs and carbon emissions for households, adding battery storage increases lifecycle costs and has mixed impacts on emissions. By 2040, solar-plus-storage systems may have up to 31% higher lifecycle costs and up to 32% higher emissions compared to solar-only systems.

Summary: Global international maritime trade has a significant impact on shipping emissions, with potential unfairness, but there is a large emission reduction potential through optimizing international trade patterns. Establishing a more systematic solution and joint efforts from the shipping industry and global trade network can effectively address climate change.

Summary: This study develops a high-resolution bottom-up model that provides hourly maps of urban surface CO2 fluxes, including contributions from buildings, traffic, human respiration, soil respiration, plant respiration, and plant photosynthetic uptake. The model is designed to be simple and flexible, using commonly available data as input, making it transferable to different locations. Applied to Basel, Switzerland, the model captures the dynamic spatiotemporal variability of urban CO2 fluxes and estimates lower emissions from buildings and traffic compared to the local inventory.

Summary: This article introduces a new city-level emission dataset, Carbon Monitor Cities, which provides daily estimates of emissions for 1500 cities in 46 countries over the course of three years. The dataset disaggregates the emissions into five sectors and aims to improve the timeliness and temporal resolution of city-level emission inventories.

Summary: The impacts of climate change, such as water scarcity and increased air temperature, pose significant challenges for the development of the electricity supply system, particularly in countries like Iran. This study used an econometric approach to project electricity demand in Iran across four sectors, considering the impact of changing air temperature. It also investigated the effects of water scarcity on the optimal expansion of the power system, modeling each power plant unit separately using a bottom-up energy system optimization modeling platform called TIMES. The results indicate that fuel price increases significantly affect capacity and cooling technology choices, with renewables becoming more attractive in scenarios with high fuel and water prices and carbon taxes.

Summary: The study found that GHG emissions from mill residues-based pathways can be 15-52% lower than those of pulpwood-based pathways, with logging residues falling in between. Furthermore, it suggests that screening bioenergy projects based on specific feedstock types alone is not sufficient, as GHG emissions of a pulpwood-based pathway in one state can be lower than those of a mill residue-based pathway in another state. The available biomass supply usually consists of several woody feedstocks, and its composition is region-dependent.

Summary: This study quantifies carbon emissions associated with the production and use of electricity in European countries, revealing significant variations between countries. The carbon intensity of electricity has shown a clear reduction trend since 1990 for most European countries, with the carbon intensity of low voltage electricity in the EU decreasing from 641 gCO2eq/kWh in 1990 to 334 gCO2eq/kWh in 2019, and expected to continue in the future.

Summary: This study evaluates the net greenhouse gas (GHG) emissions of 30 cogeneration plants in France compared to a detailed definition and assessment of their related baseline. The results show that, on average, AD plants in the French energy context do not significantly mitigate GHG emissions due to lower carbon storage in soils compared to the baseline. However, there is significant variability among AD plants, with a third of them effectively mitigating GHG emissions.

Summary: Reservoirs are crucial for human societies, but their carbon emissions have a significant impact on global climate change. This study reveals that global reservoir carbon emissions peaked in 1987 and have been gradually declining since, mainly due to decreasing carbon dioxide emissions as reservoirs age. However, reservoir-induced radiative forcing continues to rise due to ongoing increases in reservoir methane emissions.

Summary: This study examines the relationship between carbon dioxide emissions and demographic, socioeconomic, and household factors in 1451 communities across Canada. Using quantile regression models, the results show that population and affluence are the most important factors influencing total community emissions and per capita emissions. Additionally, population density and poverty are also associated with emissions. The findings suggest that emission reduction policies should consider the diversity of community characteristics.

Summary: Inefficiencies in the transmission and distribution of electricity can result in compensatory electricity generation and air pollution. This study estimates the air pollutants associated with aggregate and non-technical losses at national and subnational scales using life cycle assessments and uncertainty analyses. The global analysis indicates significant emissions, such as 1 Gigatonne of CO2eq. Investments in T&D infrastructure can enhance the cost-effectiveness of renewable energy in a decarbonized system.

Summary: This study developed a spatially explicit database of dairies in California, calculating CH4 emissions based on operating permits and California-specific reports, and estimated the impact of mitigation strategies. The results show that implementing digesters at existing or planned 106 dairies in California will significantly reduce CH4 emissions.

Summary: This study introduces a new temporally and spatially resolved inventory emission model (MEET) and applies it to compressor station emissions to investigate the discrepancy between inventory emission estimates and actual measurements. The results suggest that current measurement methods may underestimate uncertainties in emission estimates, while the use of MEET can better capture the temporal and spatial variation in observed emissions.

Summary: This study analyzes the characteristics of process parameters in three lean gas ethane recovery processes and establishes a prediction and multiobjective optimization model for ethane recovery and system energy consumption. A new method for comparing ethane recovery processes for lean gas is proposed, and the addition of extra coolers improves the ethane recovery. The support vector regression model based on grey wolf optimization demonstrates the highest prediction accuracy, and the multiobjective multiverse optimization algorithm shows the best optimization performance and diversity in the solutions.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.

Summary: This study uses survey data from the Loess Plateau in China to evaluate the impact of social interaction on the adoption of soil and water conservation (SWC) technology by farmers. The study finds that social interaction increases the likelihood of farmers adopting SWC, and internet use moderates this effect. The positive impact of social interaction on SWC adoption is more pronounced for farmers in larger villages and those who join cooperative societies.
