A new version of the ERTAC EGU code, v3.0, is now available. The new version of the code simply ports v2.2 to work with Python v3.x, so this upgrade was more about retesting features than actual code changes. James at MDE was coded the port and I focused on the testing.
The new code base is available on github: https://github.com/bukim1/ERTAC-EGU-Emission-Projection-Tool. I hope others can put the code to good use.
