The sending of one email produces ~0.000001 tons of CO2 equivalent, which adds up quickly! Take the UK for example, if every email user in the country were to send one less email per day, that would reduce carbon emissions by 16,433 tons, or the equivalent of ~81,000 flights from London to Madrid. – WTF Fun Facts

UK has 16 billion accounts? 24 per capita?
yes, and I think sending a physical mail would produce much, much more than 1g of CO2
I’m guessing they are factoring the electricity production necessary for the time it takes to type on a computer and then read?
So, that makes 1gram of CO2 for sending 1 e-mail? That sounds rather unbelievable.
