Question

what is the greenhouse warming potential of carbon dioxide? 100 0 1

Explanation:

The greenhouse warming potential (GWP) of carbon dioxide ($\text{CO}_2$) is defined as 1 (by convention, it is the reference gas for measuring GWP, so its GWP is set to 1 over a specific time horizon, typically 100 years). The option "100" is incorrect, and "0" is also incorrect as $\text{CO}_2$ is a greenhouse gas with a GWP of 1.

Answer:

The option with "1" (the bottom option in the given choices).
