Clean Technology for Resource, Energy and Environment (CTREE) is pleased to announce an update to its publication schedule. Starting with Volume 2026, the journal will adopt a biannual issue structure, while continuing to publish accepted articles online on a continuous basis.

Under this model, manuscripts will be made immediately available online upon completion of peer review and production, ensuring rapid dissemination of cutting-edge research. Each article will then be formally assigned to one of the journal’s two annual issues for citation, indexing, and archival purposes.

This enhancement reflects CTREE’s commitment to strengthening editorial organization, improving visibility of published research, and providing a clear, consistent framework for authors, readers, and indexing services. The journal continues to uphold rigorous peer review standards, serving as a leading platform for high-quality research in clean technology, sustainable energy, resource management, and environmental innovation.

The editorial team extends its sincere gratitude to our authors, reviewers, and editorial board members for their ongoing support in advancing CTREE as a high-impact, internationally recognized scholarly publication.
