TOTO: Environmental strategy for water by Yasutoshi Shimizu, TOTO

  1. 1. TOTO Environmental strategy for water タイトル サブタイトル
  2. 2. UN-Water Conference 2013 Environmental strategy for water =CO2 reduction by water saving= Yasutoshi Shimizu Kanako Toyosada (TOTO Ltd., Japan)
  3. 3. 1. About TOTO Sanitation ware (toilets)   Bathrooms , Kitchens   Tiles, Ceramics Hydrotect/Tiles (Photocatalyst) Air-Bearing Slides, Ferrules ■ Company name TOTO LTD. ■ Established   ■ Headquarters May 15, 1917 : Subsidiary Company : Business Office Japan : Affiliate Company ■The group’s overseas hubs    15 countries, 31 hubs 3
  4. 4. 1. About TOTO ■Company Endeavors CO2 Sanitation ware (toilets)   Bathrooms , Kitchens   Products, Services Company Continuously improving water-saving performance Manufacturing stage impact CO2 Emisions (Kg-CO2/unit・year) Ex. Toilet flushing water reduction rate = 3% /year Impact reduction by products C150E Amount of water per full-flush CS series NEW CS series RESTICA series NEOREST A Reduce the amount of NEOREST AH NEOREST AH NEOREST AH・RH water used per half-flush NEOREST AH・RH ※ Only Floor Drain 4
  5. 5. 2. Benefits of water-saving in Japan Water resources conservation Water savings Determined methodology and calculation factors. Contribution Potential in 2020 was evaluated CO2 emissions reduction Energy saving Pump Waterwork s Filtration plant Sewer systems 5
  6. 6. 2. Benefits of water-saving in Japan Water resources conservation Water savings Energy saving CO2 emissions reduction The policies that promote water saving began to act. Contribution Potential in 2020 was evaluated 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 ・ Housing Eco-point subsidy for toilet ・ Domestic credit system ・ Joint Crediting Mechanism from 1990 Expanded toward developing countries 6
  7. 7. 3. Expanding of water-saving project toward other Asian nations ( Lo w rate ( ) Sani tation high use ) In developing countries, progress of urbanization (modernization) increases per capita water & energy demands greatly. Water systems have been constructed Water systems are under construction Population Sanitation in 2007 use rate ( million ) 100% <100% to ≥30% <30% 685.3 4061.2 1471.0 Typical countries Japan, U.S., Canada Indonesia, Vietnam, Mexico India, Cambodia, Nepal Domestic   water   usage ( L/day ・ capita ) 442 132 114 Water-saving project mitigates water and energy issues such as suspension of water supply and blackouts. 7
  8. 8. 3. Contribution to developing countries Electricity consumption   ( MW ) ■ The contribution of water saving to a stable electric power supply    in Vietnam The influence of hot showers on peak power consumption Electricity consumption Time The spread of hot showers pushes up peak power consumption. The spread of water-saving showers can mitigate blackout risks. 8
  9. 9. 3. Contribution to developing countries Vietnam Japan China Energy consumption rate of water   (kwh/m3) 0.66 0.85 1.32 CO2 emission factor of electricity (kg-CO2/kwh) 0.58 0.41 0.84 CO2 emission factor of water (kg-CO2/m3) 0.39 0.44 1.11 CO2 reduction potential by water saving 4.8 1.0 1.8 (% ratio to whole emission) CO2 reduction by water saving is effective also in other Asian countries.
  10. 10. 3. Contribution to developing countries The main obstacle is that momentum for water saving has not been fermented in Vietnamese society. ■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. Institutional design has been planed in the project area: Vietnam   ⇒  Water-saving campaign with the Vietnamese government using carbon credit (≒ subsidy) and certification.
  11. 11. 3. Contribution to developing countries Carbon credit produces Joint Crediting Mechanism Scheme Rapid urbanization induces mass consumption of water and energy Japanese government + Company Japan Subsidy Watersaving products Hotel Vietnam 2 CO2 reduction s no ssi m OC i e CO2 offset Carbon credit BaU Present Carbon credit Watersaving project Water-saving project mitigates water and energy issues 2011-13‥Feasibility study in China, Vietnam and other ASEAN nations 2014‥‥Plan to start a water-saving credit project in Vietnam 11
  12. 12. 3. Contribution to developing countries ■ Framework of Minimal Infrastructure for water saving JCM utilizes low-carbon city development plan (water scenario) construction support JCM-applied product selection standard Fermentation of a water-saving momentum Local Partner Credits Subsidy Japanese Ⅱ government Ⅰ Government organization Business+ campaign Counterpart country government Consumer market Prominent buildings Certification Water saving campaign Business partners expansion Full-scale business deployment Credits Ⅲ Subsidy Minimal infrastructure design standard PPP business Waterworks system Sewer system Public utilities market
