What affects global warming potential?
The GWP depends on the following factors: the absorption of infrared radiation by a given gas. the spectral location of its absorbing wavelengths. the atmospheric lifetime of the gas.
What is global warming potential and how it is measured?
The Global Warming Potential (GWP) was developed to allow comparisons of the global warming impacts of different gases. Specifically, it is a measure of how much energy the emissions of 1 ton of a gas will absorb over a given period of time, relative to the emissions of 1 ton of carbon dioxide (CO2).
What has the highest global warming potential?
Gases with high GWPs will warm the Earth more than an equal amount of CO2 over the same time period….Source.

How CFC is responsible for global warming potential?
While acting to destroy ozone, CFCs and HCFCs also act to trap heat in the lower atmosphere, causing the earth to warm and climate and weather to change. Taken together greenhouse gases are expected to warm the planet by 2.5 to 8 degrees Fahrenheit by the end of century.
Which greenhouse gases have the highest global warming potential?
What are the high GWP gases and why are they a concern? The high global warming potential (GWP) greenhouse gases include hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulfur hexafluoride (SF6).
Which gas is responsible for global warming?
Carbon dioxide
Global Warming Potential (100-year): 1 Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities.
What is global warming potential with example?
The Global Warming Potential (GWP) of a greenhouse gas is its ability to trap extra heat in the atmosphere over time relative to carbon dioxide (CO2). For example, methane (CH4) breaks down quite quickly, the average methane molecule stays in the atmosphere for around 12 years.
How is global warming measured?
Climate change is most commonly measured using the average surface temperature of the planet. Year-on-year, natural fluctuations can be seen on top of this long-term warming. For this reason, scientists traditionally use a period of at least 30 years to identify a genuine climate trend.
Which gases are responsible for global warming?
Earth’s greenhouse gases trap heat in the atmosphere and warm the planet. The main gases responsible for the greenhouse effect include carbon dioxide, methane, nitrous oxide, and water vapor (which all occur naturally), and fluorinated gases (which are synthetic).
Which gas has the lowest global warming potential?
R-717
The refrigerant with the lowest GWP (Global Warming Potential) is R-717.
How CFCs destroy the ozone layer?
Once in the atmosphere, CFCs drift slowly upward to the stratosphere, where they are broken up by ultraviolet radiation, releasing chlorine atoms, which are able to destroy ozone molecules. When sunlight returns in the spring, the chlorine begins to destroy ozone.
How humans can reduce the level of greenhouse gases?
We can reduce emissions by shifting to alternative technologies that either don’t need gasoline (like bicycles and electric cars) or don’t need as much (like hybrid cars). Using public transportation, carpooling, biking, and walking, leads to fewer vehicles on the road and less greenhouse gases in the atmosphere.
