Application of the HJ Biplot Methodology to Variation Greenhouse Gas Emissions in International Companies

The quantifying and reporting of greenhouse gas emissions is one of the most important tools for monitoring and auditing proposed to mitigate climate change, and it also directly affects business. It is thus vital at this time that we learn in detail whether firms actually report on greenhouse gas emissions and make the account entries that must be included within it. This research has a twofold objective: first to analyse the report on greenhouse gas emissions of international firms in the 2007, 2008 and 2009 period and to see what kind of variation occurs in CO2 emissions between 2006-2007, 2007-2008 and 2008-2009. Secondly we shall use the biplot methodology to represent emissions variations in firms grouped into geographic areas. To do so we group only the 89 firms in our study into the geographical areas of the Europe (EU), North America (NA), Asia (AS), and South America (SA). As regards the variation in CO2 emissions, it is noteworthy that variation in CO2 emissions for the 2006/2007 period are located closer to companies in North America, variation in CO2 emissions for 2007/2008 are located closer to European Union companies and very strikingly, the variation in CO2 emissions for the 2008/2009 period are located closer to companies in Asia and South America. This leads us to conclude that companies located in developing countries are nowadays the most aware of climate change and the need to reduce emissions.
