Educating for a Greener Future: Sustainability Thinking in International English Language Textbooks

Background/purpose. Education is crucial for fostering sustainability awareness and thinking among university students in a world increasingly defined by mounting environmental crises. Textbooks, as fundamental learning resources, have the potential to shape the minds of global citizens by offering insights into contemporary environmental challenges. This study aimed to investigate the promotion of sustainable thinking in international English language textbooks by incorporating Green Education elements throughout various aspects of the Unlock English series.

Materials/methods. In light of the research objectives, a series of textbooks (A1, A2, B1, and B2 levels) from the Unlock series has been analyzed using content analysis and criteria developed by the researchers, which covered various dimensions of Green Education.

Results. The findings revealed that the textbooks moderately included Green Education components, primarily focusing on increasing students' environmental awareness. However, there was a noticeable lack of content aimed at developing personal environmental values, critical thinking skills, and active participation in action-oriented activities. In contrast, the textbooks were found to have the potential to enhance sustainability thinking among university students.

Conclusion. The study concluded that there is a need for a more balanced inclusion of Green Education components across textbooks of various language proficiency levels to promote holistic, sustainable thinking.

ANNOUNCEMENT

Message from the Editor-in-Chief,

We would like to inform our authors, reviewers, and stakeholders that EDUPIJ has entered Scopus’s re-evaluation process, as officially communicated (dated 2025-12-09). This assessment is a standard quality assurance practice applied to indexed journals and aims to ensure sustained editorial quality, ethical integrity, and alignment with Scopus’s evolving evaluation framework.

EDUPIJ welcomes this process and views it as an opportunity to further consolidate its editorial governance, strengthen publication ethics, and enhance peer-review rigor.

Strengthening Editorial and Ethical Standards

To ensure full compliance with international best practices and to proactively address Scopus evaluation criteria, the following measures have been formally implemented:

1. Selective Acceptance Policy for 2026 and Beyond

In response to increased submission volume in 2025 (see Journal Metrics: https://edupij.com/index/sayfa/18/journal-metrics), EDUPIJ will adopt a more selective acceptance policy starting in 2026 and continuing in the years ahead. In doing so, the geographic distribution of authors will also be taken into account to ensure that editorial decisions are informed by transparent, year-to-year submission and authorship patterns. Acceptance rates will be carefully aligned with editorial capacity to ensure a rigorous double-blind peer review process supported by active reviewer engagement and uncompromised editorial oversight. This policy reflects our commitment to quality-driven growth rather than volume-based expansion, and it directly addresses observations that the geographic spread of authors has changed significantly during the same period by ensuring that any such shifts are systematically monitored and considered within our quality assurance framework.

In line with this approach, we have adopted a Publication Volume Policy, enacted on 2025-12-07, which establishes clear upper limits on annual publication volume and defines a framework for maintaining EDUPIJ’s output at sustainable, long-term levels, comparable to pre-2025 volumes under normal conditions. This policy is also publicly available at https://edupij.com/index/sayfa/41/publication-volume-journal-metrics-policy.

From 2026 onwards, our objective is to maintain a moderate and stable annual volume, prioritising quality and selectivity rather than growth.

2. Enhanced Author and Manuscript Integrity Screening

All submissions now undergo mandatory integrity checks, including automated screening for retraction history and potential ethical risks prior to peer review. These procedures are designed to safeguard originality, research integrity, and transparency at every stage of the editorial process.

3. Establishment of a Publication Ethics Review Committee

A dedicated Publication Ethics Review Committee has been constituted to evaluate high-risk submissions, oversee ethical investigations when necessary, and ensure consistent adherence to COPE guidelines and internationally recognized publishing standards. All ethical decisions are documented and managed through a structured, transparent process.

Ongoing Commitment:

EDUPIJ remains firmly committed to rigorous double-blind peer review, transparent editorial policies, responsible scholarly communication, and the advancement of high-quality educational research at an international level.

Our journal continues to demonstrate steady progress in terms of international visibility, indexing coverage, and citation performance. We are confident that the Scopus re-evaluation process will further support the journal’s long-term sustainability and academic impact.

We sincerely thank our authors, reviewers, and the broader scholarly community for their continued trust and contribution to EDUPIJ.

Sincerely,
Prof. Turgut Karaköse, Editor-in-Chief
