             CORPORATE PROPERTY ASSOCIATES 16 - GLOBAL INCORPORATED

                    CERTIFICATION OF CHIEF FINANCIAL OFFICER
                           PURSUANT TO RULE 13a-14(a)

I, John J. Park, certify that:

1. I have reviewed this Quarterly Report on Form 10-Q of Corporate Property
Associates 16-Global Incorporated (the "Registrant");

2. Based on my knowledge, this quarterly report does not contain any untrue
statement of a material fact or omit to state a material fact necessary to make
the statements made, in light of the circumstances under which such statements
were made, not misleading with respect to the period covered by this quarterly
report;

3. Based on my knowledge, the financial statements, and other financial
information included in this quarterly report, fairly present in all material
respects the financial condition, results of operations and cash flows of the
Registrant as of, and for, the periods presented in this quarterly report;

4. The Registrant's other certifying officers and I are responsible for
establishing and maintaining disclosure controls and procedures (as defined in
Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial
reporting (as defined in Exchange Act Rules 13a-15(f) and 15(d)-15(f)) for the
Registrant and we have:

      a)    Designed such disclosure controls and procedures, or caused such
            disclosure controls and procedures to be designed under our
            supervision, to ensure that material information relating to the
            Registrant, including its consolidated subsidiaries, is made known
            to us by others within those entities, particularly during the
            period in which this quarterly report is being prepared;

      b)    Designed such internal control over financial reporting, or caused
            such internal control over financial reporting to be designed under
            our supervision, to provide reasonable assurance regarding the
            reliability of financial reporting and the preparation of financial
            statements for external purposes in accordance with generally
            accepted accounting principles;

      c)    Evaluated the effectiveness of the Registrant's disclosure controls
            and procedures and presented in this quarterly report our
            conclusions about the effectiveness of the disclosure controls and
            procedures, as of the end of the period covered by this quarterly
            report based on such evaluation; and

      d)    Disclosed in this quarterly report any change in the Registrant's
            internal control over financial reporting that occurred during the
            Registrant's most recent fiscal quarter (the Registrant's fourth
            fiscal quarter in the case of an annual report) that has materially
            affected, or is reasonably likely to materially affect, the
            Registrant's internal control over financial reporting; and

5. The Registrant's other certifying officers and I have disclosed, based on our
most recent evaluation of internal control over financial reporting, to the
Registrant's auditors and the audit committee of the Registrant's board of
directors (or persons performing the equivalent functions):

      a)    All significant deficiencies and material weaknesses in the design
            or operation of internal controls over financial reporting which are
            reasonably likely to adversely affect the Registrant's ability to
            record, process, summarize and report financial information; and

      b)    Any fraud, whether or not material, that involves management or
            other employees who have a significant role in the Registrant's
            internal controls over financial reporting.
