CO2 equivalent (CO2e) emissions include the emissions of other greenhouse gases (GHGs) such as methane (CH4), nitrous oxide (N2O), water vapor (H2O), and ozone (O3).  Policies setting a stabilization goal for all GHGs might be more efficient, as emissions reductions of certain GHGs might be cheaper than equivalent reductions in CO2 emissions.  CO2 equivalent policies might also be more effective, as it might be easier to monitor and control emissions of certain GHGs.  Conversely, some GHGs emissions might prove costly to monitor.  Nonetheless, focusing on all GHGs may allow for policies that take into account the different GHG emissions of different sectors, allowing policymakers to tailor their emission control policies to the particular sectors, regions, or other groups that emit particular GHGs.  Care must be taken, however, to avoid improperly calculating the Global Warming Potentials (GWPs) of the various GHGs, otherwise an inefficient emissions control policy may result.
