A motion by the Greens will again call on the Parliament's lower house to declare a climate emergency.
The party will move the motion during Private Members' Time on March 18.
Greens leader Cassy O'Connor wrote to Premier Peter Gutwein on Thursday to advise him of the motion.
"As members of Parliament, we have a responsibility to our constituents to listen to scientists and to the calls for action from Tasmanians across the political spectrum," Ms O'Connor said.
"A climate emergency declaration won't directly solve the huge challenges we face as an island community, but it will frame future decision making and policy.

"After all, the first step to addressing any problem is to acknowledge it exists."
Ms O'Connor said her party would be presenting a motion to the floor members from all political persuasions could support.
In May last year, the Greens also introduced a motion seeking the Parliament declare a climate emergency which passed the lower house after substantial amendments were made including the removal of the word "emergency" from the motion by the government.
Local, state and federal governments across the world have declared a climate emergency, including the Launceston and Hobart councils.
