Each Hong Kong mall uses up to 15,000 pieces of paper towel a day, posing a threat to the environment.
That works out to about 5.5 million pieces a year.
World Green Organization has launched a campaign to cut down on paper towel use, urging citizens to use hand dryers more often, Headline Daily reports.
The group interviewed 80 malls, commercial buildings, residential clubhouses and offices during October to November.
The results showed that 90 percent of the interviewees provide paper towels as standard amenities, according to news website hk01.com.
About 40 percent of the companies said they are willing to reduce the amount of paper towels and provide hand-dryers as an alternative.
Still, more than 60 percent said they are not prepared to reduce the amount of toilet paper they provide, fearing customers would think it is unhygienic.
The organization cited statistics from JCI Lion Rock which show that each mall consumes about 15,000 pieces of paper towel a day.
Each ton of paper towel requires 17 trees and pollutes 20,000 gallons of water, it said.
Dr. William Yu, chief executive of the World Green Organization said citizens should bring handkerchiefs to wipe their hands.
Tam Kwok-hun, manager of a mall in Sheung Shui said the daily influx of people to malls could reach 50,000, which means if one person uses one paper towel, the daily consumption will hit 50,000 pieces.
