I, R. Andrew Kingston, Chief Executive Officer of DynaMotive Energy Systems
Corporation, certify that:

1.     I have reviewed this Annual Report on Form 20-F of DynaMotive Energy
Systems Corporation;

2.     Based on my knowledge, this 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 report;

3.     Based on my knowledge, the financial statements, and other financial
information included in this 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 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)) for the Registrant and 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 report is being prepared;

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

       (c)   Disclosed in this report any change in the Registrant's internal
        control over financial reporting that occurred during the period
        covered by the 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 officer(s) and I have disclosed,
based on our most recent evaluation of the internal control over financial
reporting, to the Registrant's auditors and the audit committee of
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 control 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 control over financial reporting.
