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...

background: iran is located in the seventh rank in terms of co2 emissions resulting from the fuel combustion in the world. gas compressor booster stations, due to the several sources of contaminants, are causing the release of large amounts of co2 and ch4, which will cause climate change therefore, estimating the emissions of the gases from oil and gas, different processing units are necessary....

introduction earth's atmosphere plays an important role in preventing the temperature decrease. one of the principal factors of environmental pollution and the main source of earth's climate and biodiversity changes is greenhouse gas emissions from various sources, particularly agricultural sector. agriculture sector is considered as a major source of greenhouse gas sequestration, including me...

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 ...

The U.S. EPA State and Local Climate Change Program is unveiling the Emission Inventory Improvement Program Volume VIII: Estimating Greenhouse Gas Emissions, a revised guide for states conducting greenhouse gas emission inventories. The revised guidance is accompanied, for the first time, by the State Tool for Greenhouse Gas Inventory Development, a user-friendly inventory spreadsheet tool inte...

Decisions can be taken to increase energy efficiency and to mitigate the emissions to the environment by examining the energy audit and greenhouse gas (GHG) emissions footprint of crop production in different ways and in different regions, with comparable principles. In this study, energy consumption and energy indices of tomatoes production in four regions of Iran including East Azerbaijan...

Greenhouse gas emission trading programs have been initiated in the European Union, Canada and the United States in an effort to harness market forces to efficiently reduce greenhouse gas emissions. Three major methods for reducing or offsetting greenhouse gas emissions are purchasing greenhouse gas emission reduction credits, purchasing renewable energy certificates, and improving energy effic...

introduction energy is one of the most important commodities that make up a large proportion of international trade. among all the countries in the world, iran is known as semi-industrial developing country which is rich in energy such as non-renewable energy in particular fossil fuel. use of energy affects the environment in various forms of pollution. in the agricultural sector, the fao repor...

This paper discusses results from the MATTER project (MATerials Technologies for greenhouse gas Emission Reduction). The goal of the project is to provide more insight into the potentials to reduce greenhouse gas (GHG) emissions in Western Europe through changes in the production of materials and the use of materials. GHG emission reduction is one of the key environmental problems for the susta...
