Abstract:
... Our food system is very resource and emissions intensive and contributes to a broad range of environmental impacts. We have developed cradle-to-market greenhouse gas emissions estimates of supplying fresh tomatoes to 10 of the largest metropolitan areas in the United States and applied a linear optimization algorithm to determine the optimal tomato distribution scheme that will minimize tomato-rel ...

Abstract:
... In order to promote low-carbon sustainable operational management of the wastewater treatment plants (WWTPs), automatic control and optimal operation technologies, which devote to improving effluent quality, operational costs and greenhouse gas (GHG) emissions, have flourished in recent years. There is no consensus on the design procedure for optimal control/operation of sustainable WWTPs. In this ...

Abstract:
... Energy consumption prediction is an integral part of planning and controlling energy used in the building sector which accounts for 40% of the global energy consumption and a significant portion of greenhouse gas emissions. However, very few studies focused on the combined effect of building characteristics, building geometry, and urban morphology on energy performance. Such a research gap is addr ...

Abstract:
... Though aerobic composting is commonly used in kitchen waste (KW) disposal, the high-oil and high-salt characteristics of KW could affect composting efficiency and lead to the land using risk of produced fertilizer. The impact of hydrothermal pretreatment (HTP) and addition of compound microbial agent (CMA) on compost maturity, greenhouse gas (GHGs) emissions and bacterial community during the kitc ...

Abstract:
... The temporal variation of greenhouse gas concentrations in China during the COVID-19 lockdown in China is analyzed in this work using high resolution measurements of near surface △CO₂, △CH₄ and △CO concentrations above the background conditions at Lin'an station (LAN), a regional background station in the Yangtze River Delta region. During the pre-lockdown observational period (IOP-1), both △CO₂ a ...
... High phosphorus steel slag and carbonized rice husk are two common wastes characterized by high generation and low secondary use values. Through the reduction of high phosphorus steel slag by biomass, both wastes were fully utilized, thus reducing the negative impact on the environment. In this study, variables such as temperature, time, and amount of reactants were changed to determine the optima ...

Abstract:
... The environmental Kuznets curve has received widespread attention from researchers and policymakers for its ability to vividly capture the dynamics between economy and environment. While attempts have been made to validate the environmental Kuznets curve and harness its explanatory power in different dilemmatic scenarios (e.g., economic development and greenhouse gas induced climate change), these ...

Abstract:
... Inland waters have been increasingly viewed as hotspots for greenhouse gas (GHG) emissions owing to their strong capability to intercept and mineralize carbon from the terrestrial environment. Although small waterbodies in humid subtropical climates have the potential to emit considerable amounts of GHG, their emission patterns have remained understudied. This study involved intensive measurements ...

Abstract:
... The co-culture of rice and poultry/aquatic animals has become a popular strategy to ensure the critical ecological functions and economic benefits of this ecosystem in recent years. Yet, quantitative synthetic effects of co-culture models on ecological functions and economic benefits in paddy fields are poorly understood. This study conducted a meta-analysis of 4707 observations from 224 published ...

Abstract:
... In this study, the biochar (BC) produced from sawdust, sludge, reed and walnut were used to support sulfidation of nano-zero-valent-iron (S-nZVI) to enhance nitrate (NO3−-N) removal and investigate the impact on greenhouse gas emissions. Batch experiment results showed the S-nZVI/BCₛₐwdᵤₛₜ ₍₂:₁, ₅₀₀₎, S-nZVI/BCₛₗᵤdgₑ ₍₂:₁, ₉₀₀₎, S-nZVI/BCᵣₑₑd ₍₂:₁, ₇₀₀₎, and S-nZVI/BC wₐₗₙᵤₜ ₍₂:₁, ₇₀₀₎ respectivel ...

Abstract:
... Offshore wind power contributes to the decarbonization of the power system; however, its green development faces many challenges, including environmental impact concerns, scale limitations, and grid parity to go carbon neutral. This study applies life cycle assessment (LCA) to evaluate the potential environmental impact of China's first high-power prototype windfarm. The environmental impact of th ...

Abstract:
... The sewer system is a significant source of hydrogen sulfide (H₂S) and greenhouse gases which has attracted extensive interest from researchers. In this study, a novel combined dosing strategy using nitrate and calcium peroxide (CaO₂) was proposed to simultaneously control sulfide and greenhouse gases, and its performance was evaluated in laboratory-scale reactors. Results suggested that the addit ...

Abstract:
... With the growing number of electric vehicles in the transportation sector aimed at reducing greenhouse gas emissions, vehicle-to-grid (V2G) technology can play an important role in stabilizing electricity grids. An electric vehicle could be used as an energy storage system (ESS) that provides electricity to the grid when required. Several studies have evaluated the economic performance of differen ...

Abstract:
... Patterns of protein intake are strong characteristics of diets, and protein sources have been linked to the environmental and nutrition/health impacts of diets. However, few studies have worked on protein profiles, and most of them have focused on specific diets like vegetarian or vegan diets. Furthermore, the description of the environmental impact of diets has often been limited to greenhouse ga ...
... I propose a model of firm heterogeneity and limited managerial commitment within an industrial equilibrium, where firms use natural resource and produce greenhouse gases. Firms are allowed to merge and commit to reducing greenhouse gas emissions. Greenhouse gas levels produce climate shocks that can close firms. Three hypotheses are produced from the model that are empirically verified. First, fir ...

Abstract:
... Citizens can play an important role in disseminating scientific information about climate change, if motivated to do so. However, expressing green positions has the potential to negatively affect people’s reputation, by making them look judgmental for instance. In three experiments among US and UK participants (N = 1197), we investigate the reputational costs of sharing statements about climate ch ...

Abstract:
... The International Maritime Organization (IMO) has set a target to reduce greenhouse gas (GHG) emissions from shipping by at least 50% in 2050 compared to 2008. Some studies focused on negative cost mitigation measures to achieve this goal, while it is almost a consensus that alternative maritime fuels with low or zero direct GHG emissions are needed. This article gathered data from implementation, ...

Abstract:
... Hydrogen energy is a promising energy source that is environmentally friendly due to its long-term, large-capacity storage and low greenhouse gas emissions. However, the mass production of hydrogen is still technically difficult due to limitations in efficiency, stability, and cost, even though it can satisfy all of the current energy demands. Water splitting using an electrocatalyst is an efficie ...
