There is often a doubt that what big impact a monthly paper statement can have. It could be enormous.
Estimates for US suggest if every household were able to switch to paperless bank billing, this would save an estimated 16,500,000 trees per year or about a 46,000 acre forest, 396,000 tonnes of CO2 a year, 495,000 tonnes of air pollution per year and gain almost 2,145,000 tonnes of oxygen per year.
