For (1), my mistake - the commodity balance was generated with the default COM_LIM=LO, as you say it should be. It was set to the default ENV COM_LIM.
For (2), a COM_BNDNET was defined for the commodity. However, removing this and leaving only COM_AGG and FLO_EMIS defined for the commodity does not change the behaviour. It looks like an EQE_COMPRD equation is created to produce VAR_COMPRD, which is equal to VAR_COMNET in the COMBAL equation. However, since COMPRD must be greater than zero by default, and the emissions are negative, this causes an infeasibility. So I think it might work if the emissions are positive, but not if they are negative.
