 ## Equations specification
 The following set of modelling equations should be included in ESM.
-The environmental objective $\mathbf{LCIA_{tot}}$ is defined as the sum of the impacts of the infrastructure, operation, 
-and resource parts, namely $\mathbf{LCIA_{infra}}$, $\mathbf{LCIA_{op}}$, and $\mathbf{LCIA_{res}}$.
+The environmental objective ${LCIA_{tot}}$ is defined as the sum of the impacts of the infrastructure, operation, 
+and resource parts, namely ${LCIA_{infra}}$, ${LCIA_{op}}$, and ${LCIA_{res}}$.
 The infrastructure impact is derived from the normalized specific impact ($lcia^{norm}_{infra}$), which is computed 
 from the infrastructure LCI dataset. This value is then divided by the technology's lifetime in the ESM 
-($n_{ESM}$), and scaled with the technology's installed capacity ($\mathbf{F}$). The operation and resource impacts are 
+($n_{ESM}$), and scaled with the technology's installed capacity (${F}$). The operation and resource impacts are 
 respectively derived from the operation and resource normalized specific impacts ($lcia^{norm}_{op}$ and 
 $lcia^{norm}_{res}$), which are respectively computed from the operation and resource LCI datasets, and scaled 
-with the annual energy production (\mathbf{F_t} \times t_{op}$).
