I have a material that was extracted 425 km from the manufacture point and transported by truck. After manufacture the material was shipped via rail to the project site which is 2076 km. The distance from manufacture to project site would quality as a regional material, but I'm unsure of how the distance travelled by truck plays into this. Both distances are within the acceptable limits for truck and rail, but my only thought was to do a weighted average, which I don't believe would make this a regional material (425/800 + 2045/2400 = 1.38). Am I going about this in the right way? Distance directly from extraction to project site is 2234 km. Any help would be greatly appreciated!
