This paper studies the modeling and optimization of energy use and greenhouse gas emissions of eggplant production using artificial neural network and multi-objective genetic algorithm in Guilan province of Iran. Results showed that the highest share of energy consumption belongs to diesel fuel (49.24%); followed by nitrogen (33.30%). The results indicated that a total energy input of 13910.67 ...

Concerns about climate change and the increasing cost of fossil fuels have led to interest in the development of renewable biofuel pathways for reducing greenhouse gas (GHG) emissions. The use of corn residue as a potential source of biomass feedstock for cellulosic ethanol production has been favored as cost effective. Previous research has shown that crop residue removal can cause a loss of s...

Australia’s transport greenhouse gas (GHG) emissions are high and continue to grow, with current levels approximately one-third higher than in 1990 and increasing by around 1% annually. Efforts to curtail and reverse this growth have not been successful to date. In recent times, national policy development and debate has centred on market-based mechanisms to reduce GHG emissions, namely an emis...

Post-consumer waste is a small contributor to global greenhouse gas (GHG) emissions (<5%) with total emissions of approximately 1300 MtCO 2-eq in 2005. The largest source is landfill methane (CH 4), followed by wastewater CH 4 and nitrous oxide (N 2 O); in addition, minor emissions of carbon dioxide (CO 2) result from incineration of waste containing fossil carbon (C) (plastics; synthetic texti...

The production of animal-based foods is associated with higher greenhouse gas (GHG) emissions than plant-based foods. The objective of this study was to estimate the difference in dietary GHG emissions between self-selected meat-eaters, fish-eaters, vegetarians and vegans in the UK. Subjects were participants in the EPIC-Oxford cohort study. The diets of 2,041 vegans, 15,751 vegetarians, 8,123 ...

The environmental impacts of municipal solid waste (MSW) management have been highlighted in China, due to the continually increasing amount of MSW being generated and the limited capacity of waste treatment facilities. Of particular interest is greenhouse gas (GHG) mitigation, aided by the Kyoto Mechanisms. China is an important case study for this global issue; however, an analysis of the ent...

Introduction: Greenhouse gas (GHG) emissions have caused environmental effects. Food production is one of the sources of GHGs. This study aimed to suggest dietary scenarios for decreasing GHG emissions. Materials and Methods: GHG emissions in the target population of Urmia city, Northwest Iran, were investigated using a modeling approach. Three dietary scenarios were modeled and analyzed to ev...

This work aims to elucidate notions concerning the ideal operation and greenhouse gas (GHG) emissions benefits of combined heat and power (CHP) systems by investigating how various metrics change as a function of the GHG emissions from the underlying electricity source, building use type and climate. Additionally, a new term entitled ‘‘CHP Attributable” reductions is introduced to quantify the ...

This paper examines the GHG emission of industrial process in Shenyang city, in the Liaoning province of China, using the 2006 IPCC greenhouse gas inventory guideline. Results show that the total GHG emissions of industrial process has increased, from 1.48 Mt in 2004 to 4.06 Mt in 2009, except for a little decrease in 2008. The cement industry, and iron and steel industries, are the main emissi...
