1. A hydraulic fracturing system, comprising:
a plurality of hydraulic fracturing rigs comprising one or more fuel consumption components and one or more emissions components;
one or more controllers configured to control operation of the plurality of hydraulic fracturing rigs; and
a site controller in communication with the plurality of hydraulic fracturing rigs and the one or more controllers, the site controller being configured to:
receive operational data associated with the one or more fuel consumption components or the one or more emissions components,
determine a set of operational parameters based on the operational data and emissions output predictions for the plurality of hydraulic fracturing rigs,
output, to one or more computing devices or the one or more controllers, the set of operational parameters;
receive operational feedback data after outputting the set of operational parameters;
determine to modify the set of operational parameters based on the operational feedback data; and
modify the set of operational parameters based on determining to modify the set of operational parameters.
