The global warming potential (GWP) of each gas is defined in relation to a given weight of carbon dioxide for a set time period (for the purpose of the Kyoto Protocol a period of 100 years) GWPs are used to convert emissions of greenhouse gases to a relative measure (known as carbon dioxide equivalents CO 2 equivalents)148 147 152 154 158 149 779 154 7 148 149Greenhouse gas emissions could increase from 55 gigatons of CO2 equivalents (GtCO2e) in 19 to over 80 GtCO2e in 50 an almost 50 percent increase Causes of CO2emissions CO2emissions are mostly a result of burning fossil fuels such as coal, oil and gas
