In this paper, we present a dynamic model modified with emission permit banking and pollution abatement, and investigate the effect of emission permit banking and pollution abatement on the production–inventory strategy of the firm. After introducing emission permit banking and pollution abatement, the cost function consists of the inventory holding and production costs, the cost of investment ...

In Brazil, increasing air pollution in urban areas has led to a rise in respiratory diseases among children and the elderly and has also been the main cause of hospital admissions. This study aims to evaluate the air pollution levels in Vitória, capital of Espírito Santo State, Brazil, in comparison to Brazilian legislation and recent World Health Organization (WHO) guidelines, analyzing the sp...

Soft handovers are an essential part of a WCDMA network functionality. Taking full advantage of SHOs requires careful setting of parameters. In addition, state of the network affects the performance of SHO algorithm. Pilot pollution, i.e., too many hearable pilots, can make it difficult for SHO algorithm to perform properly, and DL transmit power as well as signalling capacity can be wasted for...

In this study we examine the extent to which firms pass back the cost of pollution regulation to workers in the form of lower wages using a unique matched employer-employee dataset for Shanghai. The benefits and costs of pollution regulation in China are important topics to study as China comes under increasing pressure to move from a single-minded focus on energy-driven economic growth to a mo...

Increasing concerns about climate change have given rise to the formation of International Environmental Agreements (IEAs) as a possible solution to limit global pollution effects. In this paper, we study the stability of IEAs in a repeated game framework where we restrict to strategies which are simple and invariant to renegotiation. Our main contribution to the literature on IEAs is that we a...

The deleterious effects of ambient air pollution on human health have been consistently documented by many epidemiologic studies worldwide, and it has been calculated that globally at least seven million deaths are annually attributable to the effects of air pollution. The major air pollutants emitted into the atmosphere by a number of natural processes and human activities include nitrogen oxi...

The urban environment is where an increasing share of the world’s population resides, where the most commercial energy is consumed, and where the impacts of pollution are imposed the most. In the urban environment, because of its complex structure, the air pollution appears unpredictable covering narrow area. The AirScope system is developed for that kind of micro-scale air pollution management...

Biomass allocation is an important plant trait that responds plastically to environmental heterogeneities. However, the effects on this trait of pollutants owing to human activities remain largely unknown. In this study, we investigated the response of biomass allocation of Phragmites australis to petroleum pollution by a ¹³CO₂ pulse-labelling technique. Our data show that plant biomass signifi...
