ABSTRACT
According to the Intergovernmental Panel on Climate Change, anthropogenic emissions of carbon dioxide are the most important single contributor to the risk of global warming. The bulk of anthropogenic emissions of carbon dioxide arise from energy consumption especially in the transport sector (motor vehicles) and electricity generation (coal fired power stations). Any economic policies such as taxes or subsidies that affect energy prices in market economies also affect energy consumption and, hence, carbon dioxide emissions and the risk of global warming.
