Question

Method and material used for green house effect

Answer 1

Greenhouse gas (GHG) emissions occur throughout the lifecycle of the materials we consume. Energy is required at all stages, from raw materials acquisition and farming, to manufacturing and processing, to transportation and use, and finally to disposal. The lifecycle stages also have non-energy GHG emissions, such as process emissions from industry (e.g. perfluorinated compounds from aluminum production, CO2 from converting limestone to lime, CFC/HFCs from refrigeration) and methane from landfills. The graphic below illustrates these materials-related GHGs.
