- 92% – Peak spam levels late in the year.
The carbon footprint of spam email can be phenomenal. The share of spam was at 81% of all the emails, that is 72.9 trillion emails in the year 2009. To store/forward/transmit such a vast amount of email may take huge amount of infrastructure that consumes lot of power. All this is to send the emails to the junk folder where they are never opened. Something must be done to address this than just filtering, which does not address the real problem.
