Summary: Although natural gas is considered a standardized commodity fuel, its life cycle impacts vary significantly due to its greenhouse gas intensity, particularly methane emissions from the production stage. Research shows variability in production-stage methane emissions by state in the United States, contributing to the overall environmental footprint of natural gas consumption.

Summary: Methane abatement policies are important for addressing climate change, but there is a lack of evidence on public attitudes towards these policies. A survey conducted in four European countries (N = 5629) found that public support for methane regulations remains stable regardless of cost information and policy framing.

Summary: This study calculates and analyzes the greenhouse gas emissions of one of the largest gas refining companies in the Middle East for the first time, finding that CO2 and CH4 emissions mainly come from direct sources and fugitive emissions are minimal. The study suggests the need for further research in different regions to gain a more comprehensive understanding of the adverse effects of gas emissions on human populations.

Summary: This article highlights the greenhouse gas emissions in the Scottish salmon aquaculture industry and calls for the development of comprehensive emissions reductions measures. Case studies of two aquaculture operators and comparison with data from the Carbon Disclosure Project reveal imbalances in mitigation strategies and identify potential routes for carbon emission reductions.

Summary: Methane emissions from natural gas have a significant impact on Paris climate targets, but locating and measuring these emissions is challenging. The use of satellites, such as TROPOMI, has made it easier to locate and quantify emissions. This study calculates the minimum detection limits of TROPOMI across North America for different campaign lengths and compares them with emission inventories. The results show that TROPOMI can capture a range of emissions, from 0.04% to 14.4% in a day measurement and from 4.5% to 41.1% in a yearlong campaign, assuming gas sites contain super-emitters.

Summary: Methane emissions along the natural gas supply chain play a critical role in the climate benefits of switching from coal to natural gas in the power sector. For Germany, with methane leakage rates below specific break-even levels, transitioning to natural gas can significantly reduce CO2-equivalent GHG emissions.

Summary: The study found that Americans have more positive feelings towards natural gas compared to other terms used to describe it, with varying perceptions between Democrats and Republicans. The choice of terminology can greatly influence the public's understanding of fossil fuels and their support for related policies.

Summary: Cities play a crucial role in climate change mitigation, but there has been a lack of methodology to quantify the actual emission reduction potential of climate interventions implemented by cities. This study aims to create a framework to assess the positive climate impacts of cities and regions, and presents step-by-step guidance for calculations. A case study of the Finnish city of Espoo is used to further develop and test the regional handprint approach. The research finds that a city's carbon handprint can be determined through ownership, operating environment, and projects. The regional carbon handprint approach provides a useful tool to quantify and communicate the innovative climate actions implemented by a city.

Summary: Coastal methane emissions play a dominant role in the global ocean methane budget, but there is a lack of systematic, high-resolution, and long-term data, leading to uncertainty in coastal budgets. By studying continuous methane concentrations, delta C-13-CH4 values, and methane sea-air fluxes, researchers found that the distribution of methane in coastal habitats is patchy and highly variable over time. The concentrations of methane in different habitats can vary greatly, and there are specific seasonal and diurnal patterns. High-resolution measurements are needed to improve the reliability of methane estimates and understand the contribution of different habitats to regional and global methane budgets.

Summary: Research on carbon footprint is crucial for improving the climate environment by managing energy use, reducing emissions, and addressing climate change. This study used bibliometric analysis to establish a knowledge map of collaborative research and identified key trends and opportunities for future research. The findings highlight the continuous growth of carbon footprint research, the shift from conceptual methods to specific problems, the importance of international cooperation, and the potential integration of carbon footprint with other impact assessments.

Summary: There is an urgent need to control global warming caused by humans to achieve a sustainable future. The increased popularity of cryptocurrencies has led to a rise in greenhouse gas emissions and high energy consumption. This review compares the energy consumption and carbon footprints of cryptocurrencies with countries and centralized transaction methods, and proposes solutions to reduce their environmental impact. Case studies on cryptocurrency networks, namely Ethereum 2.0 and Pi Network, are presented to discuss their potential in addressing the identified challenges.

Summary: The health sector has a role to play in decarbonization efforts and should focus on fair pathways to net-zero healthcare that address health and socioeconomic inequalities. It has been recognized in the past decade that not only is the health sector at risk from climate change, but it is also a major emitter of greenhouse gases. In November 2021, the World Health Organization and its partners launched the COP26 Health Programme and established the Alliance for Transformative Action on Climate and Health to support sustainable and low-carbon health systems. Fair distribution of the remaining carbon budget and health benefits is crucial, considering the disparities in health financing, carbon emissions, and unmet health needs worldwide.

Summary: The concept of soil health is increasingly used as an indicator for sustainable soil management. This study evaluates the damages to soil health attributed to land developments in Illinois, USA, and reveals the loss of soil carbon and associated social cost of carbon dioxide emissions. The study highlights the importance of considering soil health in land development and suggests expanding soil health legislation to include soil-based 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.
