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...
In Australia, dairy cattle account for ~12% of the nation’s agricultural greenhouse-gas (GHG) emissions. Genetic selection has had a positive impact, reducingGHGemissions fromdairy systemsmainly due to increased production per cow,which has led to (1) requiring fewer cows to produce the same amount ofmilk and (2) lowering emissions per unit of milk produced (emission intensity). The objective o...

Synthetic nitrogen (N) fertilizer has played a key role in enhancing food production and keeping half of the world's population adequately fed. However, decades of N fertilizer overuse in many parts of the world have contributed to soil, water, and air pollution; reducing excessive N losses and emissions is a central environmental challenge in the 21st century. China's participation is essentia...
Climate change presents a global health threat. However, the provision of healthcare, including dialysis, is associated with greenhouse gas emissions. The aim of this study was to determine the carbon footprints of the differing modalities and treatment regimes used to deliver maintenance hemodialysis (HD), in order to inform carbon reduction strategies at the level of both individual treatment...
Global warming that occurs due to emissions from a country or a country group was studied from two different points of view. Firstly, warming effect caused by Finnish emissions from 1900 to 2100 was assessed using a model that describes removal of greenhouse gases from the atmosphere by pulse response functions, and calculates the radiative forcing caused by an increase in atmospheric concentra...
Energy use and greenhouse gases (GHG) emissions in rainfed canola production in north eastern Iran were analyzed to find measures to reduce energy use and GHG emissions. Four production scenarios, i.e. a high-input, a low-input, a better crop management and a usual scenario, evaluated. All activities and production processes were monitored and recorded over three consecutive years. The usua...
Reliable inventory information is critical in informing emission mitigation efforts. Using the latest officially released emission data, which is production based, we take a consumption perspective to estimate the non-CO2 greenhouse gas (GHG) emissions for China in 2012. The non-CO2 GHG emissions, which cover CH4, N2O, HFCs, PFCs, and SF6, amounted to 2003.0 Mt. CO2-eq (including 1871.9 Mt. CO2...
Climate change occasioned by the accumulation of greenhouse gases (GHGs) is now widely accepted as an issue which mankind needs to address. The starting point is necessarily the determination of all the sources of emissions during the life-cycles of the studied components. Post-calculation, the results ought to be presented to decision-makers in a clear manner so as to provide the basis on whic...
Biogas digesters are commonly used in livestock farming in China. The digestion process converts large amounts of raw liquid manure (RLM) to biogas digester effluent (BDE). The BDE is then stored on the farm for some time before land application as crop or orchard nutrients. Storage of RLM or BDE is associated with gas emissions, although little information is available concerning comparison of...
