FAQ

What is a ton, or is it tonne?

"Ton" is most commonly used in the USA to refer to short tons which are equivalent to 2,000 pounds.

"Tonne" or "metric ton" is equivalent to 1000 kg, or 2,204.62 pounds.

And don't get us started on long tons!

Whenever we use the word "ton" we are referring to metric tons.

Is CO₂ the same thing as carbon?

CO₂ and carbon are technically not the same thing!

While we often use them interchangeably as a shorthand, "carbon" simply refers to the element C on the periodic table which has an atomic weight of 12 g/mol.

"CO₂" is a molecule containing one carbon (C) and two oxygens (O) and has an atomic weight of 44 g/mol. This means CO₂ is 3.67 times heavier than C (carbon).

Also, when you're typing it out, it's CO2, not C02 (C zero 2)!
