1) Electricity consumption

In 2019, our Segway I2 machines did 3,100 hours and 7,100km of guided tours. The electricity consumption was 5,249 kWh. Hence a Segway electricity consumption of 1.75 Wh/hour and 0.75Wh/km.

A 2.5 hour 8 km guided tour electricity consumption is between 4.4Wh (2.5 hour x 1.75 Wh) and 5.9Wh (=8km x 0.75 Wh).

French electricity emission factor is 57g CO_{2}e /kWh (Source : Base Carbone®), hence **0.35 g **CO_{2}e emissions for a 2.5 hour guided tour.

2) Segway transportation to the tour starting point

We load our Segway I2 in a van and carry them to the guided tour starting point. The average distance (round trip) is 30km and the average load is 10 segways. The emission factor of our van is 0.65Kg CO_{2}e /km (including the construction of the vehicule and its gas consumption). So for each guided tour (1 person on 1 segway), the CO_{2 }emissions generated by the transportation are **1.95 kg **CO_{2}e
