What is Global Warming Potential (GWP)?


Since CO2 is the most abundant harmful greenhouse gas we give it special attention over the other GHGs. For example, many charts or graphs in this blog are relating emission of CO2 rather than, say CH4. CO2 has become the standard to compare other GHGs with.


The Global Warming Potential (GWP) of each GHG is shown below. [20]


The chart shows how dangerous the less-known gases are to our atmosphere. Each number means it is that many times a greater hazardous potential. It’s important that engineers and any industrialization process leaders take into account the impact of the work they are doing on the environment.
