Concerns about atmospheric emissions of greenhouse gases and operation costs are converging to increase incentives for both the electric utility and magnesium industries to rapidly locate and repair equipment leaks (Irwin, 1997). The primary culprit is sulfur hexafluoride (SF6), an invisible, non-hazardous, inert gas with near-perfect dielectric properties that is used as an insulating gas in h...

The proposal discussed in this paper is to levy a common charge on all emissions of greenhouse gases, worldwide. All countries would be covered in principle, but the proposal could be implemented with a much smaller number of countries, provided they covered most of the emissions. While all greenhouse gases should in principle be covered, this paper will address mainly carbon dioxide, quantitat...

Many firms generate large amounts of carbon dioxide and other greenhouse gases when they burn fossil fuels in their production processes. In addition, production of raw materials and other inputs the firms procure for their operations also generates greenhouse gases indirectly. These direct and indirect greenhouse gas emissions occur in many sectors of our economies. In this paper, we first pre...

growing process of industrialization in different societies, excessive expansion of industries and factories and increase transport industries, push human toward unstable development. among these problem, massive volume of pollutions is also added to the atmosphere. air pollution in industrial societies and cities is more intensive. global warming is one of the major problems of 21 century. co2...

One of the major factors, contributing to the emission of greenhouse gases in the environment is generation of pollutant gases in municipal landfills. As for the design and building of a gas collecting system, it is necessary to properly estimate the amount and type of the landfill emissions. By means of LandGEM model, this study predicts the amount and type of the landfill gases, produced for ...

The present study attempts to investigate the potential relationship between input energies, performance production of greenhouse basil, and greenhouse gases emitted from this product. The data were collected from 24 greenhouses using a questionnaire and verbal interaction with farmers. Results of the study showed that the total input energy and total output energy for basil production were 119...

Introduction Conclusions References Tables Figures Back Close Full Screen / Esc Abstract Introduction Conclusions References Tables Figures Back Close Full Screen / Esc Abstract Metrics for comparing greenhouse gases are analyzed, with a particular focus on the Integrated Temperature Change Potential (IGTP) following a call from IPCC to investigate this metric. It is shown that GWP and IGTP are...
