Hi,
I am trying to use the summing function (over regions, periods and timeslices), and the results seems to tell me this funtion will add a non-negative constraint to related variables. Is that true and/or possible to change?
The thing is, I use the cumulative emissions as a constraint to generate mitigation scenarios, while the constrainted variable (i.e. CO2) has to stay positive (zero the lowest) no matter how limited the emission space is. In this case, the model cann't use negative-emission technologies BECCS, therefore I have trouble modelling the zero-emission / negetive-emission target.
Please let me know if I have misunderstanding here, or there is some other ways to realize this modelling. Thanks a lot!

Huan.
