The head of the Environmental Protection Administration (EPA) urged the public to make an effort to observe Earth Day on April 22 to help reduce carbon emissions. Winston Dang called for people to turn off their lights for one hour during the international event.
CO2 emissions can be reduced by 0.25 kg for every person who turns off their lights. The participation of one million people would result in CO2 emissions being reduced by 250,000 kg, which is the quantity of CO2 absorbed by more than 20,000 trees in one year, according to Dang.
