Sending a brief email adds how many grams of carbon dioxide equivalent (gCO2e) in the atmosphere, according to scientists?

a. 3

b. 4

c. 5

d. 6

ANSWER: 4

Explanation:

Even a short email adds around 4 grams or 0.14 ounces of gCo2e or carbon dioxide equivalent to the atmosphere. Carbon output of hitting send on 65 mails is the same as driving a moderate sized car for 1 kilometre. Adding or CCing someone else adds another 6 grams of CO2. Close to 500 billion emails buzzed around the world each day.
