message_ix_models.project.engage.workflow.step_1

message_ix_models.project.engage.workflow.step_1(context: Context, scenario: Scenario, config: PolicyConfig) → Scenario[source]

Step 1 of the ENGAGE climate policy workflow.

If the method attribute of policy_config is “calc”, then scenario must contain time series data for variable=”Emissions|CO2” and region=”GLB region (R##)”; see calc_hist_cum_CO2(). This is typically provided by the legacy reporting. If the attribute has a float value specifying a budget directly, this condition does not apply.
