Abstract: A powertrain control unit may be configured to control an engine to optimize the emission of CO2 vs. criteria pollutants according to various duty cycle parameters. The control unit may identify a first operating condition is expected to fulfill a demand for output with an exhaust stream having a first amount of a pollutant (e.g., CO2, NOx, particulate matter), and a second operating condition expected to fulfill the demand with an exhaust stream having a reduced amount of the pollutant as compared to the first amount. The powertrain control unit may receive duty cycle information to control the engine to fulfill the demand per the second operating condition, yielding the reduced amount of pollutant in the exhaust. Duty cycle information may include speed, location, position, rotation, temperature, and/or other information. A vehicle, backhoe, bulldozer, crane, and/or combine harvester may comprise the powertrain control unit and an engine and aftertreatment system. An exhaust aftertreatment system may be remotely activated, which may reduce warmup time associated with emissions mitigation.
