Measuring carbon offsets

PAGE CONTENTS

You may have noticed that all of our offsets are listed as tonnes rather than tons. What's this all about?

The difference between tonnes and tons

When it comes to carbon offsets, all units are listed as 1 tonne of carbon dioxide equivalent (1 tonne CO2-e). This is because carbon offsets are traded as metric tons, i.e., tonnes. This is equivalent to 1,000 kilograms.

In the United States, when it comes to measurement, things are done quite a bit differently than the rest of the world. In America, a ton, also called a short ton, is equal to 2,000 U.S. pounds. However, a metric ton, when converted to pounds, is slightly larger, clocking in at 2,204.6 pounds.

Catering to a global audience

Rather than list all of our offsets as metric tons, we decided to go with the widely used shorthand of tonne. The key thing to remember is that one tonne equals one metric ton - equivalent to 1,000 kilograms. All carbon offsets are traded as tonnes. Now that you know, it's time to think about which tonne is right for you - choose the perfect offset package.
