Warrant Certificate 

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 (“Common Stock”), of CBRE Acquisition Holdings, Inc., 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. Fractional shares shall not be issued upon exercise of any Warrant. If, upon the exercise of Warrants, a holder 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 the number of shares of Common Stock to be issued to the Warrant holder. 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 $11.00 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 may be redeemed, subject to certain conditions, as
set forth in the Warrant Agreement. 

 Reference is hereby made to the further provisions of this Warrant Certificate set forth on
the reverse hereof and such further provisions shall for all purposes have the same effect as though fully set forth at this place. 
 This
Warrant Certificate shall not be valid unless countersigned by the Warrant Agent, as such term is used in the Warrant Agreement. 
 This
Warrant Certificate shall be governed by and construed in accordance with the internal laws of the State of New York.

“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 (i) at the time of
exercise a registration statement covering the shares of Common Stock to be issued upon exercise is effective under the Securities Act and a prospectus thereunder relating to the shares of Common Stock is current, (ii) at the time of exercise a
valid exemption from registration is available or (iii) through a “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.

 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.
