Summary: Governments have implemented a cap on greenhouse gas emissions to protect the environment. This study examines the optimal production strategy for producers under this policy. The results show that remanufacturing is the preferred strategy when production must be completed in a regulated region. However, if production transfer is allowed, partial production transfer becomes the optimal strategy when the emissions cap exceeds a certain threshold.

Summary: The production of materials is a significant source of greenhouse gas emissions, and policies are being implemented worldwide to increase material efficiency and promote the circular economy. Research shows that greenhouse gas emissions from material production have been steadily increasing, with a majority of the growth coming from China. The carbon footprint of materials is mainly attributed to construction and the manufacturing of durable products, and policies should focus on addressing the growing capital stocks in emerging economies.

Summary: Growing urban populations and deteriorating infrastructure are driving demands for concrete, which has no alternative that matches its functional capacity. Concrete production is a major source of greenhouse gas emissions, but the potential emissions reduction from efficient structural design decisions is not well understood. This study demonstrates that a combination of manufacturing and engineering decisions can significantly reduce GHG emissions from cement and concrete production, while also improving resource utilization and reducing other environmental burdens.

Summary: Bauxite mining can have significant impacts on the soil environment, but reforesting and fertilization strategies can help restore soil organic carbon stocks. In a study conducted in Brazil, nitrogen fertilization did not show any immediate negative effects on greenhouse gas emissions, microbial community, or environmental quality indexes. However, longer-term experiments are needed to fully understand the environmental costs and benefits of prolonged nitrogen fertilization on reclaimed mine sites.

Summary: Livestock sheds, including sheepfolds and summer cattle sheds, are significant sources of methane and nitrous oxide emissions, with animal presence leading to up to a 1100 times increase in GHG efflux compared to empty sheds. Nitrous oxide emissions showed a significant boost during and after rainfall and spring-thaw events. The study highlights the importance of considering animal sheds as intense local hotspots of GHG emissions at both local and regional scales.

Summary: This study used the EC technique based on a QCL spectrometer to measure NH3 fluxes in a typical cropland in the North China Plain. Enhanced emissions were observed after fertilizer application and persistent dry depositions after ploughing practice. The deposition fluxes measured by the EC technique were significantly lower than the results obtained by the inferential model method, suggesting the need for further validation.

Summary: This study quantified crop-specific nitric oxide (NO) emission factors (EF(d)s) at seasonal and annual scales by synthesizing measurements from field-based studies worldwide. The results showed that vegetables had the highest seasonal EF(d) compared to other crops, and rice had the lowest among cereals. Soil organic carbon, total nitrogen, pH, and fertilizer type were found to be the main factors influencing the variations in NO EF(d)s. The study provides important insights for estimating global NO emissions from croplands and highlights the significance of cash crop production as a source of atmospheric NO.

Summary: Soil physiochemical and biological properties play crucial roles in regulating nitrogen (N) transformation in soil, but the specific contributions of different soil properties remain uncertain. This study quantified the gross transformation rate of N in seven Regosolic soils in a subtropical montane agricultural landscape and identified the influences of microbial functional genes and soil properties on N transformation. The results showed that clay minerals and soil type also played important roles in regulating the rates of N transformation processes in Regosolic soils. Overall, these findings highlight the significance of clay minerals as mediators of gross N transformations in soil.

Summary: Greenhouse vegetable production in China is a growing concern due to food quality and safety worries. This study found that greenhouse soils have higher concentrations of micronutrients and macronutrients compared to adjacent arable land. The concentrations of heavy metals in greenhouse soils were lower, except for copper and zinc in the topsoil. The study also revealed the direct relationship between soil nutrient concentrations in greenhouses and the application of fertilizers and agrochemicals.

Summary: The long-term substitution of synthetic nitrogen (N) fertilizer with organic manure has been found to effectively mitigate nitric oxide (NO) emissions. However, the impact of this substitution on NO emissions over an extended period is not well understood. This study aimed to quantify the long-term effects of manure substitution on NO emissions and identify the major factors contributing to the variations. Field measurements conducted over three years showed that the cumulative NO emissions from manure substitution were significantly larger than those from synthetic fertilizer, indicating that the long-term use of organic manure did not mitigate but rather stimulated NO emissions.

Summary: Coastal wetlands are important for terrestrial carbon balance as they act as natural blue carbon sinks. However, the effects of N enrichment on Rsoil in coastal wetlands are still unclear, hindering the estimation of carbon fluxes. This study found that long-term N enrichment increased Rsoil by boosting microbial biomass carbon, and also enhanced plant growth. The results suggest that N enrichment stimulates Rsoil in coastal wetlands through interactions between soil environmental conditions and plant growth.

Summary: Urban land-use change affects biogeochemical cycling of carbon and nitrogen and associated greenhouse gas (GHG) emissions. A meta-analysis shows that urbanization increases soil nitrous oxide (N2O) emissions and reduces soil methane (CH4) uptake. These changes are driven by alterations in soil properties, such as bulk density and pH, temperature increase, and management practices, particularly fertilizer use.

Summary: Oxygen dynamics play a key role in controlling nitrous oxide (N2O) production processes in arable soils. Bacterial denitrification is the primary source of N2O emissions during the hot-wet summer, while nitrification or fungal denitrification contribute to about 50.0% of total emissions during the cold-dry winter. The findings help improve process models and develop targeted mitigation measures for N2O emissions.

Summary: Anthropogenic nitrogen loading affects the abundance of soil ammonia-oxidizing archaea and bacteria, leading to changes in soil nitrification. Climate is the most important factor determining the response of the ammonia-oxidizing community to nitrogen loading, and it affects nitrification indirectly through its influence on the ammonia-oxidizing community.

Summary: Secondary organic aerosol (SOA) formed from vehicle exhaust is a significant contributor to urban particulate matter in the atmosphere. However, there are uncertainties in the simulation of SOA by air quality models due to differences in SOA formation between vehicle types, exhaust aftertreatment devices, and oxidation conditions. This study conducted smog chamber experiments to investigate the formation of SOA from different vehicles under different conditions. The results showed that there are differences in the formation of SOA and its precursors under different conditions, highlighting the need for further examination of the characteristics of SOA.

Summary: Nested models were used to simulate variations in hydrological processes, soil water, and salt transport in the reconstruction area of the Yellow River Delta. The results showed that gate dams near the sea area were more effective in reducing water depth variations, and scenarios with 6 m gate valves had higher water depth changes than those with 3 m sluice valves. Rapid changes in soil water and salt content occurred during non-flooding periods, and the fluctuation of soil salt content was opposite to soil water content changes in different soil layers.
