This study aims to examine the role of environmental management systems, performance, and military connections disclosure carbon emissions. focuses on companies listed Indonesia Stock Exchange for period 2017-2020. Hypothesis testing using multiple linear regression. Test-F shows a stable significant model. The research results show four variables that have been proven be insignificant emission...

The design of a multimodal logistics service network with customer service time windows and environmental costs is an important and challenging issue. Accordingly, this work established a model to minimize the total cost of multimodal logistics service network design with time windows and environmental concerns. The proposed model incorporates CO2 emission costs to determine the optimal transpo...

Operating at absolute minimum cost can no longer be the only criterion for dispatching electric power due to increasing concern the environmental consideration. The emission controlled economic dispatch (ECED) problem which accounts for minimization of both fuel cost and emission is a multiple objective function problem. This paper proposed the particle swarm optimisation (PSO) metaheuristic me...

In this study, based on the Environmental Kuznets Curve (EKC) framework, we empirically examine the effects of trade openness and the level of economic development on pollution emission across the Chinese provinces. Our regression analysis shows that increasing trade openness contributes to higher pollution emission, where the effect of the former may be realized through its impacts on total fa...

BACKGROUND Persistently high sulphur dioxide (SO2) emissions from platinum group metal (PGM) smelting pose a major threat to communities located around smelters. This paper examined SO2 emission trends, emission regulations and residents' perceived health risks from exposures to such emissions at Selous Metallurgical Complex (SMC) PGM smelting facility in Zimbabwe. METHODS SO2 data from roof ...

163 Guenther et al., 2006) which models the effects of changing phenological and environmental variables on isoprene and other BVOC given species-specific basal emission rates. The isoprene basal emission rate is defined as a constant emission factor representing the capacity of a given plant species to emit isoprene under standard environmental conditions (30°C, 1000 μmol m–2 s–1 of photosynth...

Many supply chain problems involve optimization of various conflicting objectives. This paper formulates a green supply chain network throughout a two-stage mixed integer linear problem with uncertain demand and stochastic environmental respects level. The first objective function of the proposed model considers minimization of supply chain costs while the second objective function minimizes CO...

Recently, environmental concern and demand for a catalyst’s high performance have increased and many research activities focused on the operation of a three-way catalyst (TWC) at the end of its lifetime. Catalyst aging is the loss of catalytic activity over time that has crucial importance in emission of three-way catalyst.  The aim of this paper is, investigating experimentally the performanc...

Transportation network improvements are commonly evaluated by estimating average speeds from atransportation/traffic model and converting them into emission estimates using an environmental model such asMOBILE or EMFAC. Unfortunately, recent research has demonstrated that average speed, and perhaps evensimple estimates of the amount of delay and the number of vehicle stops on a ...

In industrial plants and motor vehicles basic environmental pollutants and trained human factors play a significant role for the reduction of pollution. This paper briefly describes the effect of chemical science, for the various stages used in the automotive technology training, in the Vocational Higher School in Turkish Higher Education System. The methodology used to improve the learning pro...
