Summary: This study used the NUFER-Citrus-LCA model to analyze the greenhouse gas emissions, carbon sequestration, and ways to achieve carbon neutrality in China's citrus production system. The results showed significant variations in emissions among different provinces, with Guangdong province having the highest emissions. Nitrogen fertilizer accounted for 71.5% of the total emissions. By optimizing nitrogen fertilizer management, replacing 50% of chemical fertilizer with organic fertilizer, and using cover crops, there is potential to transform China's citrus production system from a carbon source to a carbon sink. Implementation of this crop management model is crucial for achieving carbon neutrality in the Chinese citrus industry.

Summary: In the context of China's commitment to the double carbon goal, promoting agricultural carbon emission reduction is currently an important research topic. Assessing the carbon sequestration level of crops has a positive impact on enhancing agricultural carbon sinks and reducing carbon emissions. The carbon budget analysis in the Jinchang arid oasis of northwest China showed that increasing the proportion of the area planted with corn was beneficial in enhancing regional carbon sequestration, and chemical fertilizer and agricultural film were the main carbon sources.

Summary: Enhanced silicate weathering (ESW) has been proposed as a negative emission technology with significant climate change mitigation potential. However, differences between lab and real soil conditions, as well as the impact of biological processes on weathering rates, may influence the effectiveness of ESW in sequestering CO2 and reducing greenhouse gas emissions. It is crucial to include biological factors in ESW research to fully understand its climate change mitigation effects.

Summary: The rapid growth of plastics production worsens the triple crisis of habitat loss, plastic pollution, and greenhouse gas emissions. Circular strategies to achieve net-zero GHG emissions have been proposed, but their implications for overall sustainability have not been studied on a global scale. This study links a comprehensive model of plastic production and end-of-life treatment to the planetary boundaries framework and finds that even a circular, climate-optimized plastics industry exceeds sustainability thresholds by up to four times. However, improving recycling technologies and rates, combined with biomass and CO2 utilization, can bring plastics into their safe operating space by 2030. Still, achieving absolute sustainability for plastics requires fundamental changes in production and use methods.

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: A meta-analysis was conducted to investigate the effects of straw and biochar application on greenhouse gas emissions. The results showed that straw application significantly increased CO2 and CH4 emissions, while biochar amendment significantly reduced CO2, CH4, and N2O emissions. The amendments also had different effects on soil properties and microbial communities, and promoted nitrification and denitrification processes.

Summary: Agricultural activities contribute 7% to Sri Lanka's economy and account for 20% of the national greenhouse gas emissions. This study assessed the agricultural emissions in the Mahaweli H region in 2018 and identified the need for extensive carbon sequestration strategies and increased nitrogen use efficiency to achieve GHG mitigation targets.

Summary: This study analyzes the carbon footprint of a large wastewater treatment plant in central Italy, finding that energy consumption, natural gas production and transport, and nitrous oxide emissions from effluent are the most significant contributors. These findings suggest that managers of wastewater treatment plants should prioritize these aspects when taking action to mitigate carbon footprint.

Summary: After changes in tillage, it is important to assess the effects on soil organic carbon dynamics. This study found that the changes in irrigation and tillage in rice cultivation did not significantly affect the input and output of organic carbon in the soil. However, compared to agroforestry, the irrigation and tillage management systems in rice cultivation showed a negative difference between carbon inputs and outputs due to increased crop root respiration and microbial activity. Agroforestry was proven to be a carbon sink.

Summary: This study presents the aggregated emissions of greenhouse gases from different land cover categories in Finland and assesses the carbon sequestration in forests and wetlands. The study finds that the largest emission source in the land use, land-use change, and forestry sector is the loss of carbon in forest harvesting.

Summary: Biomass-fueled cogeneration plants in the Philippines utilize agricultural residues as feedstock, which in turn results in the generation of ash. This study estimates the potential amount of rice husk and rice straw generation, the energy that can be recovered, and the greenhouse gas emissions reduction potential of using the generated ash in cement-based industries. The transportation of ash and the cost of different ashes are also evaluated.

Summary: Policymakers and businesses in Southeast Asia are interested in using carbon markets to promote regenerative agriculture practices, which can help mitigate climate change by reducing soil carbon loss and increasing carbon sequestration. A review of 92 studies in the region found evidence supporting the use of practices like organic amendments, cover cropping, and conservation tillage to increase soil organic carbon (SOC) stocks. However, some practices like compost and manure addition showed increased greenhouse gas emissions, which may offset the gains in SOC. It is important to estimate the overall impact of these practices on greenhouse gas concentrations to optimize their climate change mitigation effects.
