How does the GWP of materials like XPS compare to other activities?
In considering different material choices, global warming potential (GWP) is one of my considerations, among many others. I realize that materials like XPS and closed cell spray foam have many times the GWP of materials like EPS. However, I would like to get a feel for the overall magnitude of the GWP of building material choices relative to other activities in my life, like driving a car. A big percentage change in a small contributor would be no big deal. A big percentage change in a big contributor gets more weight. Does someone on this site have data comparing the GWP of manufacturing a sheet of XPS to the GWP of burning a gallon of gasoline.
