1. Initial Screening (Pre-Review)

All submitted manuscripts will undergo a pre-screening process by the Editorial Committee to evaluate:

• Compliance with formatting and submission guidelines,
• Relevance to the conference scope and sub-themes,
• Absence of plagiarism (checked via Turnitin or iThenticate with a similarity threshold of ≤20%).

Only papers passing this initial stage will proceed to the peer review process.

2. Double-Blind Peer Review Procedure

• GCEE 2025 implements a double-blind peer review system to ensure objectivity and anonymity between authors and reviewers.
• Each paper will be assigned to two independent reviewers who are experts in the field of Civil, Environmental Engineering, or relevant interdisciplinary areas.
• Reviewer selection is based on academic credentials, field alignment, and absence of conflict of interest.

3. Review Criteria

Reviewers will evaluate papers based on the following criteria:

• Scientific originality and novelty,
• Clarity of objectives and methodology,
• Technical soundness and accuracy,
• Relevance to the conference theme,
• Quality of results, discussion, and conclusions,
• Appropriateness of references and ethical compliance.

Each criterion will be scored on a 5-point scale, and overall recommendations will be one of the following:

• Accept
• Accept with minor revision
• Major revision required
• Reject

4. Author Revision and Editorial Monitoring

• Authors will receive anonymized reviewer comments and are expected to revise their manuscript accordingly.
• Revised manuscripts will be reviewed again (if necessary) by the same reviewers.
• The Editorial Committee will verify all review outcomes and ensure that the process follows ethical standards in line with COPE (Committee on Publication Ethics).

5. Final Acceptance and Camera-Ready Submission

• Only papers that have successfully passed the full peer review process and revision stage will be accepted for presentation and publication.
• Accepted papers will be included in the conference proceedings and submitted for indexation (Scopus/WoS), depending on the partner publisher agreement.

6. Ethical Compliance

GCEE 2025 adheres to international standards of research integrity and publication ethics, including:

• Avoidance of duplicate submissions,
• Management of conflicts of interest,
• Protection of author/reviewer anonymity,
• Disclosure of funding and ethical clearance

Confirmed registrants who do not participate or who cancel will forfeit their registration fees. Refunds will not be given for no-shows. GCEE 2025 reserves the right to cancel any event if the minimum registration is not met. In the event of an GCEE 2025 cancellation, all registration fees will be refunded.

Papers that are accepted must be presented at GCEE 2025, either by the authors themselves, or via proxy. In case a paper is not presented at GCEE 2025, it shall be deemed a “no-show”. No-shows will be removed from post-conference distribution and will not be available on open-access publications.

Exceptions to this policy will be made in rare and unusual situations by the Organising Committee only if there is evidence that the no-show occurred because of unanticipated events beyond the control of the authors, and that every option available to the authors to present the paper was exhausted.

Authors of no-show papers wishing to appeal the no-show status of their paper must appeal by email to the Organising Committee no later than 2 days after the start of GCEE 2025 and must provide evidence to convincingly demonstrate that their absence was as a result of forces beyond their will and control, or that an erroneous decision was made.

Decisions on appeals will be made by the Organising Committee based on the supporting evidence provided. Failure to meet the appeals deadline will automatically result in rejection of the appeal. Possible evidence for exceptions include medical documents, death notices, and other official documents.
