Price|Carbon calculation does not work if no CO2_ETS available

When running the exe/configuration_policy.xml scenario from gcam 7 vanilla (https://github.com/JGCRI/gcam-core/blob/gcam-v7.0/exe/configuration_policy.xml), and then trying to run

generate_report(db_path=dbpath,db_name=dbname,prj_name=prjname,scenarios=scen,launch_ui=FALSE,
desired_variables = c('Price|Carbon'))

I get the following error message:

I think this has to do with CO2_ETS not being defined in vanilla GCAM. Probably you at BC3 are best positioned to come up with a formulation that both serves your purposes for scenario runs with European ETS markets, and is compatible with vanilla GCAM.
