Aircraft
During climb out I noticed a 600 lbs fuel imbalance (system 2 was 600 lbs lower than system 1). Fuel was balanced during release brief. Suspected fuel leak. Pulled up fuel synoptic page on MFD and began fuel transfer and #2 fuel was still depleting even when fuel pump was off. MFD and EICAS agreed on fuel levels. The First Officer and I agreed there was every indication of a fuel leak. We ran the QRH for fuel leak. Declared an emergency and determined that ZZZ would be the best place to divert. Nearest suitable airport. Preformed a precautionary engine shutdown per the QRH Notified dispatch Notified the flight attendants made an announcement to the passengers on final approach we received a 'FUEL 2 LO LEVEL' master warning. We determined it was erroneous and continued the approach and landed without incidence.
I contacted the flight attendant to look out the window on the right side of the aircraft to see if they could see anything coming out of the back of the wing. They called us back and told us they really couldn't get a good look of the back of the wing or the engine.
An ERJ-175 declared an emergency; shut down the right engine and diverted to the nearest suitable airport after determining they had a significant fuel leak in the number two tank.
