The German GHG target does not account for the export/import of renewable gas.
So far, in addditional_functionality.py the function add_co2limit_country() sums over all German links emitting CO2 and subtracting/adding only renewable oil related emissions. This translates to encouraging the export of renewable gas from Germany to other countries since it relaxes the GHG emission target for Germany
Since the gas buses are spatially resolved, the issue becomes more complicated than the unraveling of the oil bus.
First thoughts
In a first brainstorm session with @lindnemi we discussed the following solution which leads to doubling the number of gas storage and gas buses quadrupling of gas links.
