Global warming potential (GWP) is a measure of how much heat a greenhouse gas traps in the atmosphere over a specific time period, usually 100 years, compared to carbon dioxide. It is used to compare the impact of different greenhouse gases on global warming. Carbon dioxide is used as the baseline with a GWP of 1, and other greenhouse gases are assigned a GWP relative to carbon dioxide. For example, methane has a GWP of 28-36 over a 100-year period, meaning it traps 28-36 times more heat than carbon dioxide over that time period. Reducing emissions of gases with high GWP can help mitigate climate change.

Global Warming Potential (GWP)
Definition:
The Global Warming Potential (GWP) is a measure of the relative warming effect of a greenhouse gas compared to carbon dioxide (CO2). It quantifies how much heat a particular greenhouse gas traps in the atmosphere over a specific period, typically 100 years.
Units:
GWP is expressed in units of CO2-equivalents (CO2e). One unit of CO2e represents the warming effect of one metric ton of carbon dioxide.
Calculation:
GWP is calculated using a formula that considers the radiative properties of the greenhouse gas, its atmospheric lifetime, and its ability to trap heat. It is determined relative to CO2, which has a GWP of 1.
Significance:
GWP is a crucial metric for understanding the impact of different greenhouse gases on climate change. It allows policymakers, scientists, and industry leaders to compare the warming potential of various gases and make informed decisions about climate mitigation strategies.
Example:
- Methane (CH4) has a GWP of 28–36, meaning that one metric ton of methane has the same warming effect as 28–36 metric tons of carbon dioxide over a 100-year period.
Importance of GWP:
- Guides climate mitigation efforts by focusing on reducing the emissions of greenhouse gases with high GWP values.
- Supports the development and use of low-GWP alternatives to traditional greenhouse gases.
- Informs policy decisions on carbon pricing, emission regulations, and technology development.
Limitations:
- GWP is a simplified metric that does not consider all aspects of climate change, such as indirect effects and feedback loops.
- It is based on current scientific understanding and may be subject to revision as research progresses.
- It does not account for the potential for non-CO2 greenhouse gases to contribute to other environmental effects, such as ozone depletion or acidification.
