I come from a trade background so this might be a dumb question. If GWP is rated against 1 ton of co2. How does propane have a value less than?

There’s this article , that says it was assumed due to its chemical formula it was thought to be 3, but it doesn’t say how.

Is it that propane isn’t reacting in atmosphere to create co2?

Or is that propane has less of a blanketing on the planet due some thermal property?

Or am I completely wrong on how the GWP measuring system works?

Thanks in advance.
