Model 2: Environmental Services (IC20)

The TICCS superclass IC20 (Environmental Services) describes assets related to water, waste, and wastewater treatment, among other environmental services. For this superclass, we focus on all subclasses for which we have reported data or can predict emissions. We apply ABMs using manually retrieved, asset-specific data on waste mass (in tons) or water volume (in m3). We used different EFs for each subclass to distinguish how many tons of CO2 are released per ton of waste or water treated.

We estimate Scope 1 emissions for IC201010 (non-hazardous waste treatment) and IC201030 (waste-to-power generation) asset classes based on the following equation:

Scope 1 [tCO2e]= waste mass [tons] x EF [tCO2e/ton]

Scope 2 and 3 emissions are not predicted as they either involve non-available data (non-hazardous waste treatment) or are negligible (waste-to-power generation).

For wastewater treatment plants (IC202010 – potable water treatment, IC202020 – industrial water treatment, IC203010 – residential wastewater treatment), we estimate emissions based on the following equations:

Scope 1 [tCO2e] = waste mass [tons] x EF [tCO2e/ton]

Scope 2 [tCO2e] = waste mass [tons] x EF [tCO2e/ton]

Scope 3 [tCO2e] = volume [m^3] x EF [tCO2e/m^3]

Additionally, seawater desalination plants (IC202030) only consume electricity. Hence, we assume Scope 1 and 3 emissions to be negligible and predict Scope 2 emissions based on the following:

Scope 2 [tCO2e] = volume [m^3] x EF [tCO2e/m^3]
