Ventilation Air Methane (VAM) is a Greenhouse Gas (GHG) released by coal or mineral mining operations, it is also commonly known as Coal Mine Methane (CMM). The air pollutants from this process have a global warming potential 21 times greater than carbon dioxide, which is another well known GHG. As alternative energy technologies have developed, methane is increasingly used to generate electricity and heat. Landfills and mines represent two of the most abundant sources, however reports...

The Earth is warmed principally by the sun’s radiation which enters the atmosphere. However, not all the radiation penetrates the atmosphere as some is scattered back into space. The amount of back-scattering into space alters the amount of energy that is absorbed into the atmosphere. backscattering of this energy provides valuable information on the change of the earth’s radiation balance and how different activities (artificial and anthropogenic) can affect this delicately balanced...

The aluminium industry is the major source of perflurocarbon (PFC) emissions to the atmosphere, which are a major contributor to global warming. PFCs have greenhouse gas effects up to 10000 times that of CO2. Emissions have been reduced over the last 20 years, but further reductions are harder to achieve as all the mechanisms for PFC production are not known. In order to better understand the production of PFC on an industrial level, laboratory studies have been carried out using a small scale cell.
