Start from an imported database. Request the quantities needed for your analysis; MARIO resolves their dependencies.

I want to	Guide
Calculate output, coefficients or footprint matrices	Calculate matrices
Combine gas accounts into a GHG indicator	Calculate greenhouse gas emissions
Understand the GHG indicator and its units	GHG characterization and footprints
Measure trade and embodied supply-chain content	Trade and supply-chain analysis
Identify individual upstream paths	Structural path analysis
Read regional production shares	Inspect production mixes
Plot a matrix or a prepared result	Visualize results

Worked examples

The Examples collection connects these operations in complete analyses:

• Trace a supply chain through structural indicators, bilateral trade and embodied impacts.

• Find structural paths from final demand to an environmental impact.

• Compare GHG footprints across databases with explicit source versions, characterization and unit harmonization.

For numerical methods, memory use and solver selection, see Computation settings. The matrix catalogue lists available quantities, definitions and axes.
