Sumida Eco-points Project started as an approach to reduce greenhouse gas emissions further in June 2011.
The citizens of Sumida city get eco-points according to the reduction amount of electricity and/or gas usage compared to the same month of the previous year.
Those points are recorded on “Sumida Card” issued by the Federation of Sumida City Shopping Street, as “Sumida Points”.
The project gives 10 points per 1 kg reduction of CO2 emissions (conservation factors are as follows: 0.32 for electricity, 2.21 for gas). For example, the citizen gets 3 points per 1kWh of the reduction of electricity usage and gets 22 points per 1m3 of the reduction of gas usage.
