A STUDY ON THE REASONABLE CONVERSION OF ENVIRONMENTAL PROTECTION EFFECT BETWEEN WATER SAVING AND CARBON REDUCTION

The principle of equal price between water saving and electricity saving is used to calculate one ton of water saving is equivalent to how many tons of carbon dioxide emissions reduced. According to the water price and electricity price of Xi'an city in January 2022, saving a ton of water is equal to reducing emissions of 10.03 kilograms of carbon dioxide. It is also calculated that in the past 10 years, Xi'an Siyuan University has treated 7.554 million cubic meters of campus waste water, produced 4.961 million cubic meters of reclaimed water, and been reused for toilets flashing, road surface cleaning, and irrigation of green grass and trees. 4.961 million cubic meters of reclaimed water equivalent to reducing the emission of 49,759 tons of carbon dioxide.
