Narrative:

Crew performed normal first flight of the day preflight. The aircraft had been deiced prior to our arrival. The log showed that the aircraft had been in ZZZ for 2 days for maintenance on the left air conditioning pack. After takeoff, we had a left air conditioning high temperature message. The captain flew the aircraft as I read and performed the procedure. During climb out, a flight attendant called and said that there was an odor in the cabin. In the cockpit we smelled the normal odor of deicing fluid. A few mins later, a flight attendant called to say that the odor was getting somewhat worse. We decided to return to ZZZ and I flew the plane while the captain talked to dispatch and maintenance. Our altitude was near FL250. During the descent the flow light illuminated on the overhead pressurization panel. I increased power on the right engine, the light stayed illuminated. A flight attendant called to say that the odor and haze were now much worse. The captain turned off the left pack. About the same time the cabin altitude light illuminated. The captain took control of the aircraft. We put on our oxygen masks, declared an emergency, and started a rapid descent into ZZZ1. The passenger oxygen mask deployed automatically. I performed the smoke removal checklist and coordinated with the flight attendants, while the captain flew the aircraft and talked to ATC. We accomplished the descent, approach, and before landing checklist and landed at ZZZ1. We stopped the aircraft on the runway and asked fire rescue to inspect for any signs of fire or smoke. I opened the cockpit door to inspect the situation in the cabin and talked to the lead flight attendant and then to the captain. We agreed that an evacuate/evacuation would not be necessary. The passenger were later deplaned down the aft stairway to busses to the terminal.
