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.     Paragraph  omitted pursuant to SEC release Nos. 33-8293 and
                     34-47986.

              c.     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

              d.     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.
