Summary: Combatting climate change may be the greatest public health opportunity of the 21st century. Physicians and medical students have a significant ecological footprint, particularly those from Canada and USA. Most physicians are interested in reducing their ecological footprint, and those who engage in climate change discussions are more likely to take action.

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 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: 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: 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: The study presented emissions data of open biomass burning in Northeast China from 2001 to 2017, with crop residue burning contributing the most to the total emissions. Heilongjiang Province was the largest emitter of CO2, with forest fires and grassland fires also influencing CO2 emissions. Emissions showed significant interannual variability, peaking in 2003 and 2008.

Summary: As a major greenhouse gas emitter, the transportation sector needs special attention from policymakers. However, estimating traffic emissions often relies on limited availability of actual traffic data, hindering the transferability of estimation approaches. In this study, we propose a high-resolution estimation of traffic emissions based on open data from OpenStreetMap. By combining estimated traffic volume with emission factors, we estimated the annual average daily greenhouse gas emissions from motor traffic in Berlin to be 7.3 million t CO2 equivalent.

Summary: This study proposed a new approach to improve the estimation of open biomass burning (OBB) emissions and developed hourly gridded OBB emissions in China. The new approach, which fuses multiple active fires detected by various satellite instruments, provides more accurate estimations compared to existing datasets. This approach enables better understanding of the spatiotemporal variations of OBB emissions, enhances air quality modeling and forecasting, and supports the formulation of effective prevention and control policies for OBB.

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.
