Consider the Following Equation: GHG = GHG × Energy ×

Consider the following equation: GHG = GHG × Energy × GDP,
Energy GDP
Where GHG = world annual emissions of greenhouse gases Energy = world annual amount of energy consumed GDP = world's annual gross domestic product
The ratio GHG/Energy describes

A) the units of energy consumed per unit of greenhouse gases emitted.
B) the total units of greenhouse gases emitted annually.
C) the units of greenhouse gases emitted per unit of energy consumed.
D) the energy efficiency of greenhouse gas emissions.
E) greenhouse gas emissions expressed as a percentage of carbon- based energy consumed.
