Global warming potential (GWP)

Definition

Global warming potential (GWP) is a measure of how much heat a greenhouse gas can trap in the atmosphere over a specific time period, compared to carbon dioxide. It helps assess the impact of different gases on global warming.

Analogy

Imagine GWP as a ranking system for different types of insulation materials used in houses. Just like how some insulations are more effective at trapping heat than others, gases with higher GWPs have a greater ability to trap heat and contribute to global warming.
