As an example of estimating the environmental impact of hydrogen energy system, we calculated the emission of CO2 at hydrogen production and at transportation through gas pipelines. The emission was estimated using environmental I/O table. The CO2 emission depend strongly on the kind of primary energy. For the energy transportation, less emission was obtained in case of long distance transportation using tubes inadequate diameters than electric power transportation for the same amount of energy.
