Is the elasticity of fossil fuel consumption to global GDP declining?
Global CO 2 emissions are rising rapidly, whereas they have to be reduced rapidly . This leads us to examine the relationship between global GDP and global fossil fuel consumption: ha ve fossil fuel needs declined over time , i.e. has the elasticity of fossil fuel consumption to global GDP fallen? What role do changes in fossil fuel prices play? We find bad news: Global fossil fuel consumption closely follows global GDP, with savings in fossil fuel consumption weakening since 2000; Global fossil fuel consumption is not very sensitive to its price, or, therefore, to the taxation of CO 2 .
