The disclosed methods and systems are directed to mitigating against one or more emissions events at a facility. The method comprises receiving first emissions data associated with the facility and formatting same based on a predefined data structure or a source type associated with the plurality of emissions sources of the facility. The method further comprises tracking using one or more sensors a plurality of emissions records generated using the emissions data. The data from the tracked emissions records may be used to generate an emissions inventory that may be used to generate one or more models which are used in one or more simulations to generate second emissions data. The second emissions data may enable tracking of one or more emissions sources associated with the facility. The second emissions data may enable execution of control operations that mitigate against one or more emissions sources associated with the facility.
