The International Journal of Environmental Research is an international, interdisciplinary journal that provides a platform for researchers worldwide to publish new and innovative findings and advances in the fields of environmental science, engineering, and management.

The journal’s subject scope covers areas including air, water, wastewater, waste, soil, pollution, aquatic environments, biodiversity, hazards and disasters, environmental management, policies and regulations, energy, and climate change.

The journal’s SJR indicator reached 0.81 in 2025, and its SCImago ranking improved by 21% compared with the previous year.

In assessing the academic standing of journals, the SJR indicator considers not only the number of citations but also the prestige and quality of the citing sources. From this perspective, its improvement can indicate a strengthening of the journal’s academic standing.

In terms of scholarly output and publication, the number of articles published in 2025 reached 280. In addition, citations to articles in the journal increased to 1,283 in 2025. The growth in publication volume and citations, alongside the improvement in citation indicators, reflects growing attention from the scientific community to articles published in IJER and the journal’s strengthened role in environmental scientific discourse.

The indicators recorded in the 2025 performance report—including an Impact Factor of 4.3, an SJR of 0.81, 280 published articles, and 1,283 citations—demonstrate the upward trajectory of the International Journal of Environmental Research and the strengthening of its position in international scholarly publishing.
