Creation of Carbon Credits by Water Saving

Abstract

Until now, as a way of reducing greenhouse gas emissions from Japanese homes, the emphasis has been on reduction of energy consumption for air-conditioning and lighting. In recent years, there has been progress in CO 2 emission reduction through research into the water-saving performance of bathroom fixtures such as toilets and showers. Simulations have shown that CO 2 emissions associated with water consumption in Japanese homes can be reduced by 25% (1% of Japan's total CO 2 emissions) by 2020 through the adoption of the use of water-saving fixtures. In response to this finding, a program to promote the replacement of current fixtures with water-saving toilet bowls and thermally insulated bathtubs has been added to the Government of Japan's energy-saving policy. Furthermore, CO 2 emission reduction through widespread use of water-saving fixtures has been adopted by the domestic credit system promoted by the Government of Japan as a way of achieving CO 2 emission-reduction targets; application of this credit system has also begun. As part of a bilateral offset credit mechanism promoted by the Government of Japan, research to evaluate the CO 2 reduction potential of the adoption of water-saving fixtures has been done in the city of Dalian, in China.

Contribution of Water Saving to a Stable Power Supply in Vietnam

“…The authors have shown that the creation of a water-saving society is one viable solution for sustainable development by using Japan and Vietnam as an example [5][6][7]. The results show that the spread of water-saving equipment could reduce CO2 emissions in Japan by 1% in 2020 (compared to CO2 emissions in 1990).…”

Sustainable Water Systems

“…The need for water savings due to climate change was an important issue for two further contributions [3,4]. Shimizu et al [3] promoted the creation of carbon credits by saving water.…”

“…Shimizu et al [3] promoted the creation of carbon credits by saving water. The paper also highlights that carbon dioxide emissions can be significantly reduced through widespread use of water-saving fixtures.…”

“…These systems protect public health and safety, and restore natural and human landscapes [11]. Large-scale systems in particular help to restore and preserve vegetation and wildlife, and minimize climate change and global warming [1][2][3][4]10]. Green cities focus on the restoration of natural cycles of water infiltration and evaporation through localized treatment and groundwater recharge via sustainable drainage systems, trees, parks, roof gardens and stream restoration [11].…”

“…Most sustainable water systems comprise novel combinations of traditional and new system components that mimic and work with nature [1][2][3][4][5][6][7][8][9][10][11]. These systems protect public health and safety, and restore natural and human landscapes [11].…”
