This paper reviews the greenhouse gas emissions of prefabrication elements for residential development in Hong Kong. Prefabrication becomes a common practice in residential development in Hong Kong and is considered as a green approach. In Hong Kong, prefabrication took place at factories in Pearl River Delta. Although prefabrication reduces construction wastage, it might generate more greenhou...

in this research, energetic andexergetic analysis of calcium oxide formation, co2 emissions, andenvironmental effects during the clinker production process in rotary kilnare investigated. first the energy and exergy analysis of rotary kiln were carried out according to the first and second law of thermodynamics based on dead state, respectively. consequently, the amount of co2 emissions associa...

We propose a generalization of the classical Goody model by taking into account greenhouse gas emission effects. We develop an asymptotic approach that allows us to obtain an expression for the greenhouse gas flux via the temperature and fluid fields. We show that there is a possible tipping point in atmospheric dynamics resulting from greenhouse gas emissions, where the climate system becomes ...

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...

Overview of Issue In the past two years research has pointed towards the possibility of using urban planning as a tool to reduce greenhouse gas emissions in urban areas. For many focused on the issue of climate change, there is a consensus that atmospheric carbon dioxide should be contained at no more than twice the maximum level of atmospheric carbon dioxide that existed during the pre-industr...

We posit that feasible reversal of the growth of atmospheric CH(4) and other trace gases would provide a vital contribution toward averting dangerous anthropogenic interference with global climate. Such trace gas reductions may allow stabilization of atmospheric CO(2) at an achievable level of anthropogenic CO(2) emissions, even if the added global warming constituting dangerous anthropogenic i...

In 2015, Earth experienced the start of a strong El Niño event. El Niño events are natural fluctuations of the climate system where unusually warm water accumulates in the equatorial Pacific Ocean. El Niño events are associated with abnormal weather patterns such as strong storms in some places and droughts or flooding in others. A typical El Niño event lasts 9 months to 2 years. This phenomeno...

importance of giving researchers the freedom to follow their curiosity, without being overburdened with administrative tasks and job insecurity. “She has done a lot for research and education in the region which she governs,” said one CNRS researcher who requested anonymity, continuing: “I will certainly vote for her from the first round on.” Sarkozy has also made his positions clear, giving a ...
