No. While your greenhouse gas (GHG) emissions do not directly affect your score or any other energy performance metrics like Site/Source EUI. You don't get "credit" for any avoided emissions (from onsite green power or purchasing offsite green power) in your energy metrics because they are based solely on the amount of energy you use.
However, you can track your avoided and net emissions in Portfolio Manager. See this FAQ for more on how GHG emissions are calculated.
