This Warrant Certificate certifies that
_____________________, or registered assigns, is the registered holder of warrant(s) evidenced
hereby (the “Warrants” and each, a “Warrant”) to purchase shares of Class A common
stock, $0.0001 par value per share (“Common Stock”), of Zimmer Energy Transition Acquisition Corp., a Delaware
corporation (the “Company”). Each Warrant entitles the holder, upon exercise during the period set forth in
the Warrant Agreement referred to below, to receive from the Company that number of fully paid and non-assessable shares of Common Stock
as set forth below, at the exercise price (the “Exercise Price”) as determined pursuant to the Warrant Agreement,
payable in lawful money (or through “cashless exercise” as provided for in the Warrant Agreement) of the United
States of America upon surrender of this Warrant Certificate and payment of the Exercise Price at the office or agency of the Warrant
Agent referred to below, subject to the conditions set forth herein and in the Warrant Agreement. Defined terms used in this Warrant Certificate
but not defined herein shall have the meanings given to them in the Warrant Agreement.

 

Each whole Warrant is initially exercisable for
one fully paid and non-assessable share of Common Stock. The number of shares of Common Stock issuable upon exercise of the Warrants is
subject to adjustment upon the occurrence of certain events set forth in the Warrant Agreement.

 

The initial Exercise Price per share of Common
Stock for any Warrant is equal to $11.50 per share. The Exercise Price is subject to adjustment upon the occurrence of certain events
set forth in the Warrant Agreement.

 

Subject to the conditions set forth in the Warrant
Agreement, the Warrants may be exercised only during the Exercise Period and to the extent not exercised by the end of such Exercise Period,
such Warrants shall become void.

The Warrants evidenced by this Warrant Certificate
are part of a duly authorized issue of Warrants entitling the holder on exercise to receive shares of Common Stock and are issued or to
be issued pursuant to a Warrant Agreement dated as of [●], 2021 (the “Warrant Agreement”), duly executed
and delivered by the Company to Continental Stock Transfer & Trust Company, a New York corporation, as warrant agent (the “Warrant
Agent”), which Warrant Agreement is hereby incorporated by reference in and made a part of this instrument and is hereby
referred to for a description of the rights, limitation of rights, obligations, duties and immunities thereunder of the Warrant Agent,
the Company and the holders (the words “holders” or “holder” meaning the Registered
Holders or Registered Holder) of the Warrants. A copy of the Warrant Agreement may be obtained by the holder hereof upon written request
to the Company. Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant
Agreement.

 

Warrants may be exercised at any time during the
Exercise Period set forth in the Warrant Agreement. The holder of Warrants evidenced by this Warrant Certificate may exercise them by
surrendering this Warrant Certificate, with the form of election to purchase set forth hereon properly completed and executed, together
with payment of the Exercise Price as specified in the Warrant Agreement (or through “cashless exercise” as
provided for in the Warrant Agreement) at the principal corporate trust office of the Warrant Agent. In the event that upon any exercise
of Warrants evidenced hereby the number of Warrants exercised shall be less than the total number of Warrants evidenced hereby, there
shall be issued to the holder hereof or his, her or its assignee, a new Warrant Certificate evidencing the number of Warrants not exercised.

 

Notwithstanding anything else in this Warrant
Certificate or the Warrant Agreement, no Warrant may be exercised unless at the time of exercise (i) a registration statement covering
the shares of Common Stock to be issued upon exercise is effective under the Securities Act and (ii) a prospectus thereunder relating
to the shares of Common Stock is current, except through “cashless exercise” as provided for in the Warrant
Agreement.

 

The Warrant Agreement provides that upon the occurrence
of certain events the number of shares of Common Stock issuable upon exercise of the Warrants set forth on the face hereof may, subject
to certain conditions, be adjusted. If, upon exercise of a Warrant, the holder thereof would be entitled to receive a fractional interest
in a share of Common Stock, the Company shall, upon exercise, round down to the nearest whole number of shares of Common Stock to be issued
to the holder of the Warrant.

 

Warrant Certificates, when surrendered at the
principal corporate trust office of the Warrant Agent by the Registered Holder thereof in person or by legal representative or attorney
duly authorized in writing, may be exchanged, in the manner and subject to the limitations provided in the Warrant Agreement, but without
payment of any service charge, for another Warrant Certificate or Warrant Certificates of like tenor evidencing in the aggregate a like
number of Warrants.

 

    4 

     

    

 

Upon due presentation for registration of transfer
of this Warrant Certificate at the office of the Warrant Agent a new Warrant Certificate or Warrant Certificates of like tenor and evidencing
in the aggregate a like number of Warrants shall be issued to the transferee(s) in exchange for this Warrant Certificate, subject to
the limitations provided in the Warrant Agreement, without charge except for any tax or other governmental charge imposed in connection
therewith.

 

The Company and the Warrant Agent may deem and
treat the Registered Holder(s) hereof as the absolute owner(s) of this Warrant Certificate (notwithstanding any notation of ownership
or other writing hereon made by anyone), for the purpose of any exercise hereof, of any distribution to the holder(s) hereof, and for
all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. Neither the Warrants
nor this Warrant Certificate entitles any holder hereof to any rights of a stockholder of the Company.
