annual_ghg_emissions

module wntr.metrics.economic

annual_ghg_emissions(wn, pipe_ghg=None)

Compute annual greenhouse gas emissions [22].

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 [22]).

  Diameter (mm)	Annualized EE (kg-CO2-e/m/yr)
  102	5.90
  152	9.71
  203	13.94
  254	18.43
  305	23.16
  356	28.09
  406	33.09
  457	38.35
  508	43.76
  610	54.99
  711	66.57
  762	72.58

Return type:

Annual greenhouse gas emissions (float)
