Summary: This study applied various footprinting approaches to comprehensively evaluate the environmental impacts and economic benefits of organic rice farming and conventional rice farming. The results showed that organic rice farming can mitigate greenhouse gas emissions, but has a lower yield compared to conventional rice farming. Despite the lower yield, organic rice farming has a higher economic return.

Summary: In this study, the co-production process of biohydrogen and biofertilizer using corncob as substrate was investigated by photo-fermentation. The carbon transfer pathway was evaluated through carbon footprint analysis. The optimal corncob size of 120 mesh was determined based on the highest cumulative hydrogen yield and nitrogen release ability. The carbon footprint analysis showed the distribution of carbon element in carbon dioxide, immobilized in biofertilizer, and lost. This work is significant for biomass utilization and clean energy production.

Summary: The study reviewed methods for addressing multifunctionality in the LCA of primary metals co-production and considered their implications on environmental performance assessments. Partial subdivision combined with market prices allocation was found to provide more accurate impact assessments of metals, while economic allocation methods were more consistent than mass allocation methods.

Summary: Sustainable agricultural practices are increasingly important for global and national environmental policies and economy. This study compared the sustainability of grape production under integrated and organic management using multiple indicators. The results showed that organic management was more beneficial for most environmental aspects of the agroecosystem compared to integrated management, without affecting grape yield.

Summary: This study investigates the relationship between climate policy uncertainty and energy metals using a novel technique called cross-quantilogram. The findings reveal a significant connection between climate policy uncertainty and energy metals in terms of reducing carbon emissions, as well as the diversification benefits of energy metals over longer time periods. The insights derived from this study are valuable for practitioners, investors, and scholars.

Summary: This study used survey data from cassava ethanol plants in Guangxi to establish an ethanol production process model and conducted a life cycle assessment. The results showed that the RMF production process had more advantages in terms of energy savings and CO2 reduction compared to the CF production process. Increasing the alcohol concentration of the fermentation broth helped in reducing environmental emissions. The distillation section was found to be critical for energy saving and emission reduction.

Summary: The peanut sector in China has the potential to reduce greenhouse gas emissions and nitrogen loss. The study found that carbon and nitrogen emissions from peanut cultivation increased over the years, with some periods showing a decrease. Optimizing peanut layout is crucial for reducing environmental impact.

Summary: A new integrated methodology was developed to estimate the environmental impacts of bioethanol production from sugarcane bagasse in Mexico. The methodology included five modelling phases: bibliometric analysis, simulation, life cycle inventory, life cycle assessment, and analysis of major environmental burdens. The study found that the biofuel production and biofuel use in vehicles stages had the highest contributions to greenhouse gas emissions.

Summary: The study found that the main environmental impacts of rapeseed oil production come from the direct cultivation processes and the indirect processes of transportation and fertilizer/diesel production. Adjusting industrial layout, improving cultivation in low-yield areas, and reducing pesticide use in the hilly regions of southern China can effectively reduce environmental effects.

Summary: Localized carbon reduction strategies are vital in regions lacking top-down climate leadership, such as Georgia. The paper demonstrates the use of coupled systems in assessing sub-national climate solutions, showing how place-specific climate action plans can be derived from global and national research. By incorporating solution interdependencies and including both carbon sources and sinks, a system of 20 solutions could potentially reduce Georgia's carbon footprint by 35% in 2030 compared to business-as-usual forecasts and by 50% compared to 2005 emissions.

Summary: Data centers are integral to IT and are under increasing scrutiny for their energy consumption. However, existing literature provides a wide range of estimates with challenging calculations, making it hard to rely on subsequent estimates. This review analyzes data from 46 publications between 2007 and 2021 to assess the reliability of 258 data center energy estimates. The study reveals issues with source availability, data provenance, and methodologies, and makes recommendations for various stakeholders to improve the literature.

Summary: This study evaluates apple production in China using an environmental-economic coupled water, energy, and carbon integrated footprint (WECF) assessment method. The results indicate that apple production has environmental and economic impacts, with fertilizer production and irrigation being major contributors to environmental effects, and labor and fertilizer costs being major contributors to economic impacts. The study also suggests that adopting water-saving irrigation technologies, promoting water and fertilizer-saving technologies, and increasing apple yield per area are recommended. It is noted that compared to Europe, China's apple production still has room for improvement in terms of WECF due to backward irrigation facilities and technologies, high fertilizer consumption rate, and low apple production yield per unit area.
