Carbon Trade Crisis
Plant trees before cutting them down Rethink before cutting down trees and printing paper! One A4 Pepper 226g CO₂ = equivalent to turning on a 10W LED light for 18 hours 1 ream of 500 sheets = 113kg CO₂ = equivalent to driving a gasoline car 450km 10 sheets/day at the office = 2.26kg CO₂/day. A year = 565kg CO₂ = 25 working trees a year From the calculation of 226g is as follows: 1. Paper + Ink + Electricity Printer A4 sheet 80gsm + laser ink + printer electricity: ∼20-25g CO₂. Plus the Impact of Loss of Carbon Absorbers, 226g is used including "lost stored carbon" because 1 tree is cut down 1 mature tree absorbs ∼10-22kg CO₂/year. If 1 ream of 500 sheets = 1/8 of a tree, then the "carbon cost" per sheet is ∼25-45g. If you count young trees + factory energy + global transportation, it can go up to 200-227g. The numbers combine: Production emissions + Electricity emissions + Transportation emissions + Carbon that "should" be absorbed by trees if they are n...
