 # LCA_schaefer {#lca-schaefer}
 The method is based on the dissertation by Katharina Schäfer (2011) \cite Sch17. It is highly recommended to refer to this work for detailed insights. The method calculates the energy demand and emissions across the aircraft's life cycle phases: development, production, operation, and end-of-life. The following image shows the processes considered.

 ## General principles {#lca-schaefer-generalprinciples}
 For all processes within the four phases, an inventory analysis is conducted. The function `calculateResources` collects all relevant inputs, such as materials and energy demand. Next, `calculateEmissions` determines the resulting emissions. For background processes, data provided primarily by [GaBi Software](https://ghgprotocol.org/gabi-databases) is used, offering emission data for material extraction, fuel production, energy production, and more.

@@ -6,7 +6,10 @@ The following steps are executed within the mission class:
 - `get_mission_data`, `write_emissions_path_csv`, and `get_engine_thermodynamics_LTO`: Data from the `mission.csv` file is imported, engine data for every mission step is determined and saved in a CSV file, and the engine thermodynamics during the landing and takeoff phase according to ICAO definition are calculated.
 - Emission calculation: Depending on the defined engine carrier, the emissions will be calculated for every mission step.
     - Kerosene:
-        - The emissions of CO2, H2O, SO2, and SO4 are considered to be proportional to the fuel flow. Therefore, they are calculated via \f$ emissionMass [kg] = emissionIndex [kg_{emission}/kg_{fuel}] * fuelMass [kg]\f$.
+        - The emissions of CO2, H2O, SO2, and SO4 are considered to be proportional to the fuel flow. Therefore, they are calculated via \f$ m_{emission} = EI * m_{fuel}\f$, with
+            - \f$ m_{emission}\f$: emission mass \f$[kg]\f$
+            - \f$ EI \f$: emission index \f$[\frac{kg_{emission}}{kg_{fuel}}]\f$
+            - \f$ m_{fuel} \f$: fuel mass  \f$[kg]\f$
         - All other emissions are considered to be non-proportional. For NOx emissions, there are a P3T3 Method \cite Nor03, Boeing Fuel Flow Method 2 \cite Sch13, and the calculation based on data generated by GasTurb available. For HC as well as CO emissions, the DLR Omega method and Boeing Fuel Flow Method 2 \cite Sch13 are implemented. Additionally, there is the option to calculate the landing and takeoff cycle emissions based on constants provided by ICAO. Soot emissions can be determined via a DLR correlation based on ICAO smoke numbers or a correlation by R.B. Whyte \cite Kug05. Alternatively, it can be assumed to be proportional to the consumed fuel.
     - Hydrogen: Only H2O and NOx emissions are produced.
         - H2O is assumed to be proportional to the fuel flow.
