Full size image The life cycle method has four stages: objective and scope setting, life cycle inventory analysis, life cycle impact assessment, and life cycle interpretation. It is founded on the ISO 14040:2006 LCA concepts and framework. To determine the greenhouse gas (GHG) emissions from br...
aPaleoclimate readings taken from fossil records show that these gases, two of the most abundant greenhouse gases, are at their highest levels in the past 420,000 years. Many scientists fear that the increased concentrations of greenhouse gases have prevented additional thermal radiation from leaving...
Using intermediate (RCP 4.5) and high (RCP 8.5) greenhouse gas emission scenarios, our models predict that seven of the nine species would experience a significant reduction in their climatically suitable areas, and thus will likely influence agriculture and rural livelihoods. These results are ...
The evening image makes use of one of the most multifarious prototype images in the classic literature,having abundant emotional content and cultural contents.The evening image has the emotional characteristic of the agriculture culture and also under the influence of the ancient marriage customs culture...

the Kyoto Protocol, adopted on December 11, 1997, aiming to mitigate global climate change by emphasizing the reduction of greenhouse gas emissions. As a role model, Kyoto has implemented a series of local policies and innovative measures to integrate environmental protection into every aspect of ur...
I think that this assertion of wind and solar electricity generation being “cheapest” definitely has the claim for the number one spot.
When using renewable electricity, the process is “GHG free” (no emissions of greenhouse gas). Currently, only 4% of total H2 is produced from renewable sources [68]. This is due to a number of barriers that avert the full contribution of e-H2 in the energy transition, including the ...
A wide variety of organic materials, such as forest and agricultural residues, aquatic plants, energy crops, sewage sludge, or leftover food, could be used as energy sources and help to reduce greenhouse gas emissions and dependence on fossil fuels [1,5]. In addition, the generation of ...
