                  SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

I, Anthony Cataldo, certify that:

1.    I have reviewed this quarterly report on Form 10-Q of Green St. Energy,
      Inc. (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.    I am 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-a15(f) and 15d-15(f) 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, is made known to me by others, particularly during the
            period in which this report is being prepared;

      b.    designed such internal control over financial reporting, or caused
            such internal control over financial reporting to be designed under
            my 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 report my 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
            controls over financial reporting that occurred during the
            registrant's current fiscal quarter that has materially affected, or
            is reasonably likely to materially affect, the registrant's internal
            control over financial reporting; and;

5.    I have disclosed, based on my most recent evaluation, 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 in the design or operation of internal
            controls which could adversely affect the registrant's ability to
            record, process, summarize and report financial data and have
            identified for the registrant's auditor any material weaknesses in
            internal controls; 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.
