eMotorWerks has teamed with WattTime to launch what's claimed to be the "world's electric vehicle charging solution that minimizes greenhouse gas emissions."

This is accomplished via a smart EV charging station that can monitor the local power grid to determine when it would draw power from "particularly clean power plants - from renewables to highly efficient power plants."  The charger can be set (via smart-timing algorithms) so that it only charges when this clean energy is available.

The charger is called JuiceBox Green 40.
