annual_ghg_emissions#

module wntr.metrics.economic

annual_ghg_emissions(wn, pipe_ghg=None)[source]#

Compute annual greenhouse gas emissions [23].

Use the closest value in the lookup table to compute annual GHG emissions for each pipe in the network.

Parameters:

  • wn (wntr WaterNetworkModel) – Water network model. The water network model is needed to define pipe diameter.

  • pipe_ghg (pandas Series, optional) –

    Annual GHG emissions indexed by pipe diameter (default values below, from [23]).
