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.

Carbon Capture and Storage (CCS) is an emerging method of reducing greenhouse gas (GHG) emissions of power plants. In a process called ‘scrubbing’, the carbon dioxide emissions can be absorbed into chemical solvents consisting of amines or carbonates. Scrubbing is a well-established method of carbon capture, with virtually every commercial CO2 capture plant in operation using this process. In the process, the first step is the removal of impurities from the flue gas, such as hydrocarbons and oxides of both nitrogen and sulfur (NOx and SOx). Next the purified gas is passed through an absorption column filled with the chemical scrubbing solvent. The solvent reacts with the carbon dioxide and selectively absorbs it from the gas stream. When CO2-rich solvent is heated, the carbon dioxide is released as a nearly pure gas.

With its expertise in calculating and managing emissions data, CERC offers a range of services to assess greenhouse gas emissions, from determining the carbon footprint of a single industrial process, to compiling a greenhouse gas inventory for a whole geographical area.
CERC uses methods and emission factors laid out by the Intergovernmental Panel on Climate Change (IPCC). Emissions from transport, industrial, heating and agricultural activities are calculated and stored using the EMIT software package.

Of the almost 5 million commercial buildings in the U.S., retail buildings account for the largest energy bills and are responsible for the second largest percentage of greenhouse gas emissions, according to the EPA. There are a growing number of retail companies that are embracing the principles of sustainability, taking actions that are tangible, measurable and meaningful in reducing the use of scarce resources and improving the efficiency of their businesses. For a large company, this can add up to millions of dollars in annual savings.
