I, Shelby Brewer, certify that:

1.       I  have  reviewed  this  report  on  Form  10-Q  of  Commodore  Applied
         Technologies, Inc.;

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 periods
         presented in 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  officer 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  my
              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  report  that  has  materially  affected,  or  is
              reasonably likely to materially affect, the registrant's  internal
              control over financial reporting.

5.       The registrant's other certifying  officer 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
         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 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.
