Calculation of EE MRIO accounts (Multipliers, Footprints, impacts embodied in trade, etc) followed  standard IO methodology. We used the open source tool pymrio (https://github.com/konstantinstadler/pymrio) for the calculations.  All results are calculated through input-output analysis (IOA) following classic Leontief demand style modeling. IOA is essentially an allocation of production based impacts (here denoted $\textbf{F}$) to the goods and services that flow to final demand (here denoted $\textbf{Y}$). $\textbf{y}$).  The allocation starts from the basic production balance, where gross output $\textbf{x}$ is the sum of total intermediate demand $\textbf{T}$ (with $\textbf{1} being the summation vector of appropriate size)  and final demand. \begin{equation}  \textbf{x}=\textbf{T}*\textbf{1}+\textbf{y}  \end{equation}
