A4 coefficients

I am aware that there are European-specific global warming potential (GWP) coefficients for life cycle module A4 - Transportation, but where can North American/US A4 coefficients be found?

Thanks everyone!

Look to GREET https://greet.es.anl.gov/ from Argon National Lab:
The Greenhouse gases, Regulated Emissions, and Energy use in Technologies Model

EcoTransIT World is a great tool to calculate transportation-related emissions for A4. Input the weight, origin, destination, and modes of transport, and it will show total distance and emissions. It seems to have a fairly robust methodology behind it. Hope this helps!
