Since OAE is quite a cheap CDR option, runs might not converge because the model tries to deploy a lot of OAE. In this case, use a quantity target to limit OAE by adding something like: (2070,2080,2090,2100).GLO.tax.t.oae.all 5000 to cm_implicitQttyTarget in your config file, starting from the year in which OAE is deployed above 5000 MtCO2 / yr. This will limit the global deployment to 5000 Mt CO2 / yr in timesteps 2070-2100. As an alternative to this cost-efficient allocation, a global limit can be set via cm_33_OAE_limit_EEZ which distributes it between regions based on the size of the exclusive economic zones. This approach should only be chosen when the tax approach inhibits convergence. See q33_OAE_EEZ_limit for further reasoning. Both limitation approaches affect ocean uptake, i.e. gross OAE. * (1): ocean alkalinity enhancement is included * (0): not included

In this case, the net-negative emissions tax is applied to the difference of gross CDR of the current iteration and gross CO2 emissions based on previous iterations, and thus, gross CDR beyond net-zero CO2 is disincentivised without incentivising gross CO2 emissions.
