Temperature effect potential value GWP detection

Temperature Effect Potential GWP evaluates greenhouse gases from a molecular perspective, including the ability of molecules to absorb and retain heat, and how long they can exist in the natural environment without being destroyed or decomposed.
In this way, the contribution of each greenhouse gas to the greenhouse effect can be evaluated. GWP can also evaluate the destructive capacity of greenhouse gases at a certain time in the future, usually measured in 20 years, 100 years, and 500 years.
Generally, due to the natural decomposition and destruction mechanism, the concentration of existing greenhouse gases in the atmosphere decreases year by year, and the greenhouse effect capability also weakens. However, some CFC family gases remain in the atmosphere for a long time, and the 100-year GWP may be higher than the 20-year GWP.

Zhongke Testing provides temperature effect potential value GWP testing services.

The global warming potential of a chemical substance is related to the following factors:
• The chemical substance's ability to absorb infrared rays.
• The range of wavelengths in its absorption spectrum.
• The lifetime of chemicals in the atmosphere.

GWP is an index of the greenhouse effect produced by a substance. Evaluate greenhouse gases from a molecular perspective, including the ability of molecules to absorb and retain heat, and how long they can exist in the natural environment without being destroyed or decomposed (atmospheric lifetime).
In this way, it is possible to evaluate the proportion of each greenhouse gas's impact on the greenhouse effect, and at the same time, it can also evaluate the destructive ability of greenhouse gases in a certain period of time in the future. GWP is an indicator of the climate impact caused by greenhouse gas emissions, indicating that within a certain period of time (20 years, 100 years, 500 years), the greenhouse effect of a certain greenhouse gas corresponds to the mass of CO2 with the same effect. The GWP of CO2 is 1.0.
usually calculates GWP based on 100 years, recorded as GWP100. The Montreal Protocol and the Kyoto Protocol both use GWP100. Considering the urgency of carbon peaking, the current discussion is more appropriate to use GWP20. Unlike the ozone effect, ozone focuses on the damage to the ozone layer.
