Report of Independent Registered Public Accounting Firm

The Board of Directors of
The Dreyfus Sustainable U.S. Equity Fund, Inc.

We have examined management's assertion, included
in the accompanying Management Statement Regarding
Compliance with Certain Provisions of the Investment
Company Act of 1940, that
The Dreyfus Sustainable U.S. Equity Fund, Inc.
(the "Company")
complied with the requirements of
subsections (b) and (c) of Rule 17f-2 under the Investment
Company Act of 1940 ("the Act") as of July 31, 2017.
Management is responsible for the Company's compliance
with those requirements.  Our responsibility is to express
an opinion on management's assertion about the Company's
compliance based on our examination.

Our examination was conducted in accordance with the
standards of the Public Company Accounting
Oversight Board (United States) and, accordingly, included
examining, on a test basis, evidence about the Company's
compliance with those requirements and performing such
other procedures as we considered necessary in the
circumstances. Included among our procedures were the
following tests performed as of July 31, 2017,
and with respect to agreement of securities
purchases and sales, for the period from
May 31, 2017 (the date of our last examination) through
July 31, 2017:

Count and inspection of all securities located in the vault
of BNY Mellon in Jersey City, without prior notice to management;

Confirmation of all securities held by institutions in
book entry form (e.g., the FederalReserve Bank of Boston,
the Depository Trust Company and various sub-custodians);

Reconciliation of all such securities to the books and
records of the Company and The Bank of New York Mellon (the Custodian);

Confirmation of all securities hypothecated, pledged, placed
in escrow, or out for transfer with brokers, pledgees, transfer
agents or securities lending administrators;

Confirmation of all repurchase agreements with brokers/banks
and agreement of underlying collateral with BNY Mellon records; and

Agreement of 5 security purchases and 5 security sales
or maturities, if occurred, since our last report from the books
and records of the Company to broker confirmations.

We believe that our examination provides a reasonable
basis for our opinion. Our examination does not provide
a legal determination on the Company's compliance with
specified requirements.

In our opinion, management's assertion that
The Dreyfus Sustainable U.S. Equity Fund, Inc.
complied with the requirements of subsections (b) and (c) of
Rule 17f-2 of the Act as of July 31, 2017
with respect to securities reflected in the investment account of the
Company is fairly stated, in all material respects.

management and the Board of Directors of
The Dreyfus Sustainable U.S. Equity Fund, Inc.
and the Securities and Exchange Commission and is not
intended to be and should  not be
