Aircraft
While awaiting takeoff on Aircraft X; we smelled a strong sulfur smell. The flight attendants called to report that they were smelling the same and that passengers were also smelling the smell. We decided to return to the gate; as the smell was constant and increasing. When it was safe to do so; I accomplished the Cabin Odor QRH; at the Captain's request. We were able to return to the gate and deplane the passengers safely. Once that was accomplished; we completed the required paperwork as instructed by the QRH. We also coordinated with Maintenance; Dispatch; Operations; and the Duty Pilot.
ERJ-190 First Officer reported a fume event occurred while awaiting takeoff clearance resulting in a ground gate return.
