| **Item 1.** | **SECURITY AND ISSUER** |
|  | This Amendment No. 4 amends and supplements the statement on Schedule 13D filed with the SEC on 11/1/22, as amended by Amendment No. 1 filed 12/12/22, Amendment No. 2 filed 3/9/23 and Amendment No. 3 filed 3/16/23; with respect to the common shares of BlackRock ESG Capital Allocation Trust. This Amendment No. 4 amends Items 3, 4, 5 and 7, as set forth below. |

---

---

| | |
|:---|:---|
| **Item 3.** | **SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION** |
|  | Funds for the purchase of the Common Shares were derived from the subscription proceeds from investors and the capital appreciation thereon and margin account borrowings made in the ordinary course of business. In such instances, the positions held in the margin accounts are pledged as collateral security for the repayment of debit balances in the account, which may exist from time to time. Since other securities are held in the margin accounts, it is not possible to determine the amounts, if any, of margin used to purchase the Common Shares reported herein. A total of approximately $128,998,131 was paid to acquire the Common Shares reported herein. |

| | |
|:---|:---|
| **Item 4.** | **PURPOSE OF THE TRANSACTION** |
|  | Item 4 is hereby amended and supplemented as follows: <br> On March 22, 2023, Saba Capital Master Fund, Ltd. ("SCMF"), a private fund advised by Saba Capital, submitted to the Issuer a notice of intent informing the Issuer of its intention to nominate a slate of four independent trustee candidates-Ravi Bhasin, Ilya Gurevich, Richard Thiemann and Emmanuel Werthenschlag (the "Nominees"), for election to the Board at the Issuer's 2023 annual meeting of shareholders (the "Annual Meeting"). SCMF also notified the Issuer of its intent to present five advisory proposals at the Annual Meeting asking the Board to (1) give shareholders the right to amend the Issuer's bylaws, (2) declassify the Board so that all trustees are elected on an annual basis, (3) adopt a plurality voting standard in contested elections, (4) eliminate a control share provision in its organizational documents that strips certain voting rights from shareholders owning 10% or more of the issuer's stock, and (5) conduct quarterly tender offers for a minimum of 10% of the outstanding common stock shares of the Issuer, if the stock's trading discount to net asset value exceeded 10% in the previous quarter. <br> Each of the Nominees has entered into a nomination agreement (collectively, the "Nominee Agreement") with Saba Capital substantially in the form attached as Exhibit 2 to this Schedule 13D/A whereby the Nominees agreed to become members of a slate of nominees and stand for election as trustees of the Issuer in connection with a proxy solicitation which may be conducted in respect of the Annual Meeting and whereby, Saba Capital has agreed to defend and indemnify the Nominees against, and with respect to, any losses that may be incurred by the Nominees in the event they become a party to litigation based on their nomination as candidates for election to the Board and the solicitation of proxies in support of their election. The foregoing summary of the Nominee Agreement is not complete and is qualified in its entirety by reference to the full text of the form of Nominee Agreement, a copy of which is attached as Exhibit 2 and is incorporated by reference herein. |

You understand that it may be difficult, if not impossible, to replace a nominee who, such as yourself, has agreed to serve on the Slate and, if elected or appointed, as a trustee of the Fund if such nominee later changes his mind and determines not to serve on the Slate or, if elected or appointed, as a trustee of the Fund. Accordingly, the undersigned is relying upon your agreement to serve on the Slate and, if elected or appointed, as a trustee of the Fund. In that regard, you will be supplied with a questionnaire (the "<u>Questionnaire</u>") in which you will provide the undersigned with information necessary for the Nominating Party to use in creating the proxy solicitation materials to be sent to shareholders of the Fund and filed with the Securities and Exchange Commission in connection with the Proxy Solicitation.

You agree that (i) you will promptly complete and sign the Questionnaire, and return a copy to the person indicated in the Questionnaire, (ii) your responses in the Questionnaire will be true, complete and correct in all respects, and (iii) you will provide any additional information as may be reasonably requested by the undersigned. In addition, you agree that, concurrently with your execution of this letter, you will execute and return to the person indicated in the Questionnaire the attached instrument confirming that you consent to being nominated for election as a trustee of the Fund and, if elected or appointed, consent to serving as a trustee of the Fund. Upon being notified that we have chosen you, we may forward your consent and your completed Questionnaire (or summary thereof) to the Fund, and we may at any time, in our discretion, disclose such information, as well as the existence and contents of this letter. Furthermore, you understand that we may elect, at our expense, to conduct a background and reference check on you and you agree to complete and execute any necessary authorization forms or other documents required in connection therewith. You agree that the undersigned may use your name in any statement, filing, or other communication to the extent required by law or that is in accordance with applicable law and is reasonably required in connection with the Proxy Solicitation (including, without limitation, in its notice of nominations to the Fund, its proxy statement and its proxy card in connection with the Proxy Solicitation).

------

You further agree that you will not agree to serve, or agree to be nominated to stand for election by the Fund or any other shareholder of the Fund (other than the undersigned), as a trustee of the Fund without the prior approval of the undersigned.

In consideration of your agreement to serve on the Slate, in addition to the Proxy Related Costs, the undersigned, solely on behalf of the private funds and accounts that hold shares of the Fund (excluding, for the avoidance of doubt, Saba Closed-End Funds ETF and Saba Capital Income & Opportunities Fund, which are not a party to this letter agreement), agree (severally but not jointly) that the undersigned will defend, indemnify and hold you harmless from and against any and all losses, claims, damages, penalties, judgments, awards, settlements, liabilities, costs, expenses and disbursements (including, without limitation, attorneys' fees, costs, expenses and disbursements) ("<u>Losses</u>") incurred by you in the event that you become a party, or are threatened to be made a party, to any civil, criminal, administrative or arbitrative action, suit or proceeding, and any appeal thereof, (i) relating, solely, to your role as a nominee for trustee of the Fund on the Slate, or (ii) otherwise arising from or in connection with or relating to the Proxy Solicitation. For the avoidance of doubt, the undersigned, solely on behalf of the funds and accounts that hold the Fund, shall not be obligated to indemnify, defend, or hold you harmless from and against any Losses based upon, relating to, arising from, or in connection with your service as a trustee of the Fund. Your right of indemnification hereunder shall continue after the Annual Meeting has taken place but only for events that occurred prior to the Annual Meeting and subsequent to the date hereof that are based upon, relating to, arising from, or in connection with the Proxy Solicitation. Anything to the contrary herein notwithstanding, the undersigned is not indemnifying you for any action taken by you or on your behalf that occurs from the time you were first contacted by the undersigned up to and before the date hereof or subsequent to the conclusion of the Proxy Solicitation or such earlier time as you are no longer a nominee on the Slate or for any actions taken by you as a trustee of the Fund, if you are elected or appointed. The indemnification to which you are entitled shall be reduced to the extent, if any, that the claim for indemnification is impacted by (i) you having been found to have engaged in a violation of any provision of state or federal law in connection with the Proxy Solicitation, unless you demonstrate that your action was taken in good faith and in a manner you reasonably believed to be in or not opposed to the best interests of electing the Slate; (ii) you having acted in a manner that constitutes gross negligence, bad faith, fraud, intentional and material violations of law, criminal actions or material breach of the terms of this letter agreement or willful misconduct; (iii) you having provided false or misleading information, or omitted material information, in the Questionnaire or otherwise in connection with the Proxy Solicitation, or (iv) you being in breach of this letter agreement. You shall promptly notify the undersigned in writing in the event of any third-party claims actually made against you or known by you to be threatened if you intend to seek indemnification hereunder in respect of such claims. In addition, upon your delivery of notice with respect to any such claim, the undersigned shall promptly assume control of the defense of such claim with counsel chosen by the undersigned. The undersigned shall not be responsible for any settlement of any claim against you covered by this indemnity without its prior written consent. The undersigned may not enter into any settlement of any claim without your consent unless such settlement includes (i) no admission of liability or guilt by you, and (ii) an unconditional release of you from any and all liability or obligation in respect of such claim.

------

Each of us recognizes that, should you be elected or appointed to the Board of Trustees of the Fund, all of your activities and decisions as a trustee will be governed by applicable law and subject to your fiduciary duties, as applicable, to the Fund and to the shareholders of the Fund and, as a result, that there is, and can be, no agreement between you and the undersigned that governs the decisions which you will make as a trustee of the Fund.

This letter agreement shall automatically terminate on the earliest to occur of (i) the conclusion of the Fund's next annual meeting of shareholders (regardless of the outcome), (ii) your election or appointment to the Board of Trustees of the Fund or (iii) our communication to you of either our intent not to proceed with the Proxy Solicitation or to not include you or no longer include you in the Slate.

This letter agreement sets forth the entire agreement between the undersigned and you as to the subject matter contained herein, and cannot be amended, modified or terminated except by a writing executed by the undersigned and you. This letter shall be governed by and construed in accordance with the laws of the State of New York, without giving effect to principles of conflicts of law.

Each of us hereby irrevocably and unconditionally consents to submit to the non-exclusive jurisdiction of the courts of the State of New York and of the United States of America, in each case located in the County of New York, for any litigation arising out of or relating to this letter, and waives any objection to the laying of venue of any litigation arising out of this letter in the courts of the State of New York or of the United States of America, in each case located in the County of New York, and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such litigation brought in any such court has been brought in an inconvenient forum.

Should the foregoing agree with your understanding, please so indicate in the space provided below, whereupon this letter will become a binding agreement between us.
