Energy saving

CO2 emissionsreduction

The use of water-saving equipment provides co-benefits ： ・ Water saving 　 ⇒ 15% reduction from peak year 2006 ・ Energy saving ⇒ 1% reduction from 1990 ・ CO2 reduction ⇒ 1% reduction from 1990

Contribution Potential in 2020 was evaluated

・ Housing Eco-point subsidy for toilet ・ Domestic credit system ・ Joint Crediting Mechanism

The policies that promote water saving began to act.

Expanded toward developing countries

In developing countries, progress of urbanization (modernization) increases per capita water & energy

demands greatly.

Water-saving project mitigates water and energy issuessuch as suspension of water supply and blackouts.

The influence of hot showers on peak power consumption

■ The contribution of water saving to a stable electric power supply　　　 in Vietnam

Electricity consumption

The spread of hot showers pushes up peak power consumption.

The spread of water-saving showers can mitigate blackout risks.8

3. Contribution to developing countries

CO2 reduction by water saving is effective also in other Asian countries.

The main obstacle is that momentum for water saving has not been fermented in Vietnamese society.

The main obstacle is that momentum for water saving has not been fermented in Vietnamese society.

Institutional design has been planed in the project area: Vietnam

　　⇒　 Water-saving campaign with the Vietnamese government using carbon credit (≒subsidy) and certification.

3. Contribution to developing countries

■The background to this is low water charges.

･ Products with water-saving features are expensive.

⇒The price difference cannot be covered by the reduction in water charges.
