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...

Rising greenhouse gas emissions raise the risk of severe climate change. The household sector’s greenhouse gas emissions have increased over time as more people drive gasoline cars and consume electricity generated using coal and natural gas. The household sector’s emissions would decline if more households drove electric vehicles and owned solar panels. In recent years automobile manufacturers...

Nitrogen (N) fertilization is necessary to sustain productivity in eucalypt plantations, but it can increase the risk of greenhouse gas emissions. However, the response of soil greenhouse gas emissions to N fertilization might be influenced by soil characteristics, which is of great significance for accurately assessing greenhouse gas budgets and scientific fertilization in plantations. We cond...

Agriculture contributes about 60% of New Zealand’s total greenhouse gas emissions. Management practices for reducing these emissions will be required to meet our future international commitments. This paper presents estimates of two practical on-farm measures for reducing total greenhouse gas emissions from an average dairy farm on the West Coast of the South Island of New Zealand: 1) the incor...

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...

Assessing the biomass based electricity potential of developing nations like Cuba can help to reduce the fossil fuels dependency and the greenhouse gas emissions. The data included in this study present the evolution of electricity production and greenhouse gas emissions in Cuba. Additionally, the potentialities to produce biomass based electricity by using the most significant biomass sources ...

The state of California is expected to have significant population growth in the next half-century resulting in additional passenger transportation demand. Planning for a high-speed rail system connecting San Diego, Los Angeles, San Francisco, and Sacramento as well as many population centers between is now underway. The considerable investment in California high-speed rail has been debated for...

According to released official statistics of greenhouse gas emissions in 2010, CO2, which is produced by fossil fuels and industrial processes, accounts for 65 percent of total global greenhouse gas emissions. The transport sector, in turn, is responsible for 23% of CO2 emissions. Researchers have been claiming that car manufacturers have not made significant efforts to reduce the pollution lev...
