Summary: The increased use of vehicle electrification to reduce greenhouse gas emissions requires an accurate assessment of the carbon footprint of traction batteries. However, there is a lack of lifecycle assessments for commercial lithium-ion batteries in the literature, especially regarding the use phase. In this study, we assess the cradle-to-gate and use-phase greenhouse gas emissions of the 2020 Model Year Ford Explorer plug-in hybrid electric vehicle (PHEV) NMC622 battery. The results show that both phases are comparable and should be considered in a holistic and harmonized lifecycle assessment approach to reduce carbon footprint uncertainties and guide future battery designs.

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 paper investigates the relationship between fuel subsidy policies and environmental emissions and finds that high fossil fuel subsidies are associated with greater greenhouse gas emissions. Fuel subsidy reform can help reduce global GHG emissions, but it is not a silver bullet solution.

Summary: This review examines published records of inferred wildfire activity during major greenhouse gas-induced global warming events in the past. The review concludes that there is substantial evidence linking climate-driven wildfire changes with periods of global climate changes in Earth's history, providing information for future predictions of wildfire occurrence on a warming planet.

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: 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: The greenhouse gas analysis conducted in the Malaysian palm oil industry shows that the recycling of waste can significantly reduce carbon emissions in palm oil production. By utilizing waste as fuel and fertilizer substitutes, the environmental impact of palm oil production can be reduced.

Summary: In this study, the potential for publication bias is explored through market simulation results estimating the impact of US ethanol expansion on corn prices. A new test is provided to determine whether market simulation results are biased towards food-versus-fuel or GHG narratives. The findings do not detect a relationship between narrative orientation and corn price effects, and the approach can inform the publication bias literature.

Summary: In low- and middle-income countries, socioeconomic development has led to increased emissions of air pollutants, such as nitrogen oxides, which impact human health. However, in Africa's northern biomass-burning region, decreasing burned area and increasing GDP density have led to reductions in tropospheric NO2 levels during the dry season, showing a unique pathway for potential air quality benefits. This suggests that economic development can play a role in mitigating air pollution during highly polluted months.

Summary: Space-based remote sensing can play a crucial role in monitoring greenhouse gas emissions and removals from AFOLU sector and addressing climate change through the UNFCCC Paris Agreement. International cooperation, led by CEOS, is essential for the development and realization of a long-term roadmap for observations. This paper identifies useful data and information for supporting the global stocktake of the Paris Agreement and provides a workflow for harmonization and contribution to greenhouse gas inventories and assessments.

Summary: Crop straw management is a major issue in China's agriculture sector, with the environmental impact of straw utilization not being comprehensively assessed. Through data collection and analysis, our study found that straw utilization has shifted from open burning to retaining in fields over the years, resulting in significant greenhouse gas emissions. We propose that developing bioenergy can effectively mitigate these emissions and achieve sustainable utilization of crop straw.

Summary: This study reveals that urban methane emissions in Washington, DC, and Baltimore, Maryland exceed estimates derived from traditional inventory methods. The study shows a decreasing trend in annual emissions over a four-year period and identifies wintertime emissions to be 44% higher than summertime emissions, correlating with natural gas consumption. Spatially resolved estimates attribute a significant portion of methane emissions to the natural gas sector, supporting previous findings. This research contributes to our understanding of urban methane emissions and provides evidence for mitigating natural gas emissions.

Summary: The top-down study on methane emissions from natural gas in the Boston urban region over 8 years showed no significant trend in the loss rate, with consumption-driven losses potentially accounting for missing emissions in inventories. Comparisons with estimates from six US cities suggest that distribution and end use losses from natural gas supply chain may contribute significantly to total emissions, indicating a need for future policy action.
