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 ...
... 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:
... Aeration has been widely used in constructed wetland (CWs). However, research on greenhouse gas (GHG) emissions and measures to control GHG emissions in aerated CWs is still limited. Therefore, lab-scale aerated CWs were established in this study to explore effects of Fe–C and zeolite on GHG emissions from aerated CWs. Four groups of CWs were filled with gravel (CW-A), zeolite (CW–B), ferric-carbo ...

Abstract:
... Public food service organizations are large producers of food waste, which leads to greenhouse gas emissions and the waste of natural resources. The aim of the present article was to gain insight into reasons for food waste and possible solutions for lowering food waste in schools in Sweden. In order to do so, food waste quantification in school canteens in two Swedish municipalities and nine qual ...

Abstract:
... Genetically modified (GM) crops can help reduce agricultural greenhouse gas (GHG) emissions. In addition to possible decreases in production emissions, GM yield gains also mitigate land-use change and related emissions. Wider adoption of already-existing GM crops in Europe could result in a reduction equivalent to 7.5% of the total agricultural GHG emissions of Europe. ...

Abstract:
... Changes in household consumption patterns to low-carbon alternatives are needed to decrease global greenhouse gas emissions. Accurate perceptions about the mitigation potential of different behaviours can help consumers to reduce their emissions. With a sample of N = 547 Swiss participants, we analysed to what extent participants correctly judged the mitigation potential of different behaviours. W ...

Abstract:
... Many researchers, policymakers, and stakeholders view zero-emissions vehicles (ZEVs) as playing an important role in deep decarbonization of the transport sector. Here, we bring attention to one policy that can effectively induce ZEV sales in the long term: a ZEV sales mandate. Although three decades have passed since the first mandate was implemented in California, there is surprisingly little re ...

Abstract:
... Current rates of greenhouse gas emissions are leading to a rapid increase in global temperatures and a greater occurrence of extreme climatic events such as marine heatwaves. In this study, we assessed the effects of thermal conditions predicted to occur within the next 40 years (SSP3-7.0 scenario of IPCC, 2021) on the respiration rate, buoyant weight, morphology and recruitment of the temperate m ...

Abstract:
... The quantity of ore mined and waste rock (i.e., overburden or barren rock) removed to produce a refined unit of a mineral commodity, its rock-to-metal ratio (RMR), is an important metric for understanding mine wastes and environmental burdens. In this analysis, we provide a comprehensive examination of RMRs for 25 commodities for 2018. The results indicate significant variability across commoditie ...

Abstract:
... The urban water sector significantly contributes to energy consumption and greenhouse gas (GHG) emissions. Detailed assessment of the wastewater system input provides opportunities for improving the water, energy, and emissions nexus. The inflow of water not requiring treatment into wastewater systems is acknowledged worldwide. These undue inflows can increase the footprint of these systems. Toget ...

Abstract:
... As the effects of climate change begin to materialise across Pacific Island nations, many exposed communities are considering migrating away from their homelands. Migrants’ resettlement experiences can depend upon their reception in the host nation. However, it is unclear whether justice-based obligations will influence host attitudes toward climate migrants. Using an online survey of 238 Aotearoa ...

Abstract:
... Designing highly efficient electrodes for the hydrogen evolution reaction (HER) has attracted enormous attention owing to the urgent demand to decrease greenhouse gas emissions. However, the enormous energy loss due to an insufficient exposure of active sites caused by sluggish bubble detachment has been proven to be a critical obstacle for further enhancing the HER performance. In this study, we ...

Abstract:
... The reduction of greenhouse gas emissions is the key action to limit global warming. An important source of greenhouse gas emissions and pollution is the inefficiency of production processes. We report results from a stochastic nonparametric efficiency analysis using directional distance functions to take account of undesirable outputs like greenhouse gases. With this approach, we are able to prov ...

Abstract:
... The steel industry is responsible for a large share of the industrial energy consumption and greenhouse gas emissions and several long-term energy models have some representation of this sub-sector. It is found that models, commonly use a flow-based approach for projecting steel demand neglecting that in-use steel stocks serve as a better demand indicator than steel consumption. A stock-based meth ...

Abstract:
... Nitrous oxide (N₂O) is a potent and long-lived greenhouse gas that contributes to global warming with a global warming potential (GWP) 298 times that of carbon dioxide (CO₂). In this paper, we analyzed the trend of N₂O concentration in vertical layers of the stratosphere from 2005 to 2020 using the N₂O observed from the Microwave Limb Sounder (MLS) that is on board the Aura satellite. We found tha ...

Abstract:
... In several countries, mining taxes are applied as a mechanism to collect resources but without adequately evaluating their economic impacts. From a theoretical perspective, the implementation of royalties can be justified in the non-renewable nature of mining resources. In contrast, Pigouvian taxes aim to make productive activities internalize their environmental damages. This study illustrates th ...

... Though the magnitude of any climate change is important, regions which have a larger signal of climate change relative to the background variations will potentially face greater risks than other regions, as they will see unusual or novel climate conditions more quickly as reported by Frame et al. (Nat Clim Chang 7(6):407–411, 2017). Providing more information about signal and noise on regional sca ...

... The world’s population explosion creates a need for natural resources for energy, which will become a significant contributor to global climate change. As we all know, carbon dioxide (CO₂) is one of the most critical elements of the global greenhouse gas effect. CO₂ capture and storage innovations have piqued researchers’ attention in recent decades. Compared to other methods, membrane separation ...

Abstract:
... Methane (CH₄) is the second most important greenhouse gas after carbon dioxide (CO₂), but its global warming potential is 21–28 times that of CO₂. Coal mining accounts for 9% of global CH₄ emissions, among which 60–70% is contributed by ventilation air methane (VAM). Currently the simplest way to reduce CH₄ emissions from ventilation air is to thermally oxidize it to CO₂; however the low and chang ...
