Open Access, Broadly Recognized: 363 MDPI Journals Receive CiteScores for 2025
The 2025 CiteScore metrics have been officially released by Scopus, and the results confirm what has become a consistent pattern for MDPI's journal portfolio: broad recognition across disciplines, steady improvement across the majority of ranked titles, and a growing presence at the top of subject category rankings.
CiteScore, published annually by Elsevier's Scopus database, measures the average citations received by articles published in a journal over a four-year window. As a complement to the Journal Impact Factor, which uses a two-year window based on the Web of Science database, CiteScore provides an alternative, long-term perspective on citation performance.
The 365 MDPI journals in Scopus (as of May 2026) are indexed across a wide range of subject categories, ensuring that open access research remains highly discoverable to a global readership through one of the most widely used platforms in academic publishing.
Data Summary (2025 CiteScores)
- New Additions: 41 MDPI journals received a CiteScore for the first time.
- Trending Upward: 234 of 322 previously ranked journals (73%) saw an increase in their CiteScore compared to last year.
- High Visibility: 314 journals (86%) rank in Q1 or Q2 in at least one subject category.
- Elite Performance: 42 journals rank in the top 10% of their subject categories.
Portfolio Performance
Among the 322 journals that held a CiteScore in 2024, 234 saw an increase this year. Quartile improvements outnumbered declines across the portfolio, with 52 journals moving to a higher quartile and only 20 seeing a decline. Furthermore, no previously ranked journals were removed. The 42 journals now ranked in the top 10% of their subject categories are drawn from a strong foundation of 178 journals holding a Q1 position.
With the large majority of our indexed portfolio ranked in the top half of research fields, researchers can confidently choose MDPI to meet funder mandates for high-quality, fully compliant Open Access publishing.
Exceptional Achievements for Foods and Life
Notably, both Foods and Life achieved a 99th percentile ranking in their respective subject categories for the 2025 CiteScores. This outstanding placement positions them as leading journals in their fields and highlights the high visibility and global impact of the open access research they publish.
Journal Metrics and Beyond
Journal-level metrics describe outlets, not individual articles. An increasing number of funders and institutions—including signatories of DORA and the Coalition for Advancing Research Assessment—now explicitly encourage evaluation at the article level rather than by the journal in which research appears. MDPI supports this direction: we report CiteScore alongside the Journal Impact Factor, Journal Citation Indicator, and article-level usage data because no single number captures the full reach and contribution of published research.
Thank You
These results reflect the sustained effort of thousands of editors-in-chief, editorial board members, reviewers, and authors across every field MDPI serves. The metrics are the outcome; the work is yours.

MDPI INSIGHTS: The CEO’s Letter #35 – 30 Years of Open Science, Open Access Policies, Spain Summit, MMCS 2026 & Antibiotics 2026
Welcome to the MDPI Insights: The CEO's Letter.
In these monthly letters, I will showcase two key aspects of our work at MDPI: our commitment to empowering researchers and our determination to facilitating open scientific exchange.
Opening Thoughts

30 Years of Open Science, Built Together
This month, we officially launched MDPI’s 30th Anniversary campaign and dedicated anniversary website, marking an important milestone in our journey as an open access publisher. What began in 1996 with a single journal and the simple belief that scientific knowledge should be shared openly and freely has grown into a global publishing organization supporting more than 500 journals, 68,000 Editorial Board Members, and millions of researchers worldwide.
The anniversary page, entitled 30 Years of Open Science, Built Together, reflects on the people, milestones, and partnerships that have shaped MDPI over the past three decades. It includes a retrospective of our development, key moments in the evolution of open access, landmark research articles, journal anniversaries, an interview with the CEO, and perspectives from colleagues and partners who have contributed to our success.

Looking back, one of the most striking aspects of our journey is not simply our growth, but the broader transformation of scholarly publishing itself.
Open access has moved from a niche concept to a widely adopted publishing model, helping make research more accessible, discoverable, and impactful for researchers, institutions, policymakers, and society.
MDPI has been part of this transition and continues to invest in the people, technology, partnerships, and research integrity infrastructure needed to support high-quality open science at scale.
While anniversaries naturally encourage reflection, they are also an opportunity to look ahead. The challenges facing scholarly publishing today, including research integrity, artificial intelligence, accessibility, and global participation in science, will require continued collaboration across the research ecosystem. As we celebrate 30 years of publishing, our focus remains on supporting researchers, strengthening trust in open science, and helping shape the future of scholarly communication together.
I encourage you to visit the anniversary page, explore the milestones, and take a moment to reflect on the role each of us has played in contributing to MDPI’s story.
Thank you for being part of this journey.

Inside MDPI

Open Access Policies Continue to Accelerate Globally
One of the clearest indicators of the continued momentum behind open access is the growing number of national and institutional policies supporting, and increasingly requiring, open dissemination of research.
Around the world, governments, funding agencies, and universities are building their open access mandates, with increasing focus on transparency, rights retention, and public accessibility of publicly funded research. While these policies vary across regions, the broader direction is clear: expectations around openness and compliance continue to accelerate.
For researchers, navigating these evolving requirements can be complex and time-consuming. Supporting the research community therefore means not only publishing high-quality open access content but also helping stakeholders better understand changing requirements and emerging opportunities. At MDPI, we see this as an important part of our role within scholarly communication.
“Expectations around openness and compliance continue to accelerate”
Through the MDPI Blog, our Content team continues to publish monthly articles overviewing different countries’ relationships with open access, exploring their histories, policies, opportunities, and statistics. All this information is centralized into an article which contains brief summaries of each country, with links to all the full articles, and is updated monthly.
Recent Policy Developments
South Africa
In 2026, South Africa’s Department of Science and Innovation introduced the South African Open Science Policy. The policy states that: “Open access shall be required for publications arising from publicly funded research, and desirable for research from all sources of funding.”
The policy envisions a coordinated and broad approach to open science that will sustainably and ethically drive socio-economic development by increasing the practice of open science through policy, training, incentivization, and infrastructure.
Canada
In Canada, the Tri-Agency OA Policy on Publications was revised, removing the 12-month embargo for research that must be deposited in a repository with an open license and with author rights retained.
The Agencies argue that “societal advancement is made possible through widespread and barrier-free access to cutting-edge research and knowledge.”
Chile
Chile is a collaborative and engaged member of the global open access movement.
The National Research and Development Agency (Agencia Nacional de Investigación y Desarrollo, or ANID) is Chile’s main funding agency for R&D. It mandates that all beneficiaries must deposit the final version of their published scientific output, with an embargo period of up to 12 months, into a repository.
ANID also supports the InES Open Science funding program, which allows universities to request funding for capacity and infrastructure building. Further, Chile is an active participant in various international initiatives, such as Redalyc, SciELO, and Red de Repositorios Latinoamericanos.
Openness Beyond Research
At MDPI, openness remains one of our core values, ensuring that research outputs are freely accessible to anyone. This commitment also extends to sharing knowledge about the scholarly publishing landscape itself, which we practice on the MDPI Blog through various topics, including open access, recent advances in science, and opportunities for researchers.
As the open access landscape continues to evolve, helping researchers, institutions, editors, and partners navigate these changes will remain an important priority for us.

Thank You
I would like to thank Jack McKenna (Senior Content Specialist, MDPI) from our Content team for his ongoing work on the MDPI Blog series covering global open access policy developments. Initiatives such as this help make complex policy discussions more accessible and useful to the wider research community.

Interview with Dr. Cariny Polesca—Winner of the Sustainability Travel Award
1. Congratulations on winning the Sustainability 2026 Travel Award! Could you briefly introduce yourself and explain your research to someone with a limited scientific background?
Thank you very much! I am truly honoured and happy to receive this award.
My name is Cariny, I am from Brazil, and I have a background in chemical engineering. I am a Research Associate at the Department of Chemical Engineering at Imperial College London under the supervision of Prof. Jason Hallett. My research focuses on recovering high-value compounds from different types of biomass and industrial waste and using these compounds to develop biomaterials for different types of applications, including biomedical applications, wastewater treatment and food packaging. To make these processes more sustainable, I work with ionic liquids, which are alternative and greener solvents that can be designed for specific applications by selecting different cations and anions, resulting in different properties and costs. These solvents have low volatility and, at the end of the process, can be recovered and reused, making the overall process more cost-effective and sustainable.
2. When and how did you first learn about the journal Sustainability? What was your motivation to apply for our 2026 Travel Award?
I have read some papers related to my research area published in the journal, and while exploring the journal’s website, I found out about the Travel Award. I became interested because this award is a good opportunity to support young researchers in attending international conferences. And to be honest, I had applied previously, so this year I decided to apply again. My main motivation was the opportunity to share my research with the scientific community, establish new collaborations, and keep learning.
3. What was the biggest challenge you encountered during your research? How did you overcome it?
I believe the biggest challenge during my research was developing a multidisciplinary PhD thesis. During my PhD, I was introduced to ionic liquids and their use for protein recovery, which was initially very connected to chemical engineering and separation processes. Then, after optimising the process and characterising the recovered protein, I started developing different biomaterials for several applications, with a special focus on biomedical applications. At that point, my research expanded far beyond my original background and moved more into materials science and biotechnology. I needed to learn new concepts and processes, and started collaborating with different research groups, especially to perform biological tests on the biomaterials. In the beginning, this made me quite anxious because there was so much to learn. However, looking back now, I can say it was one of the best things that happened to me in my academic journey. I accepted the challenge, trusted the process, and developed an interest in each area I worked in. More importantly, I learned how valuable collaboration is and how to work with people from different backgrounds and countries.
4. Which conference do you plan to attend with this funding, and what aspect of your research are you most looking forward to sharing at the conference?
With this funding, I will attend the RRB 2026 in Belgium next month, where I will present two research projects that are very important to my academic journey. The first project is related to my current work at Imperial College. In this work, I have used ionic liquids to valorise lignocellulosic biomass, obtaining high-purity cellulose pulp and lignin without volatile organic solvents, thereby contributing to the development of a simpler and more sustainable process for scale-up and subsequent processing. The second project is related to my PhD and focuses on the use of ionic liquids for dissolving chicken feathers and developing 3D-printed keratin-based scaffolds for tissue engineering applications.
5. Which emerging trends or key research topics in your field do you believe will be of most interest to your research community in the coming years?
I believe that one of the most important research topics in my field will be the development and scale-up of sustainable and circular biorefinery processes for biomass and waste valorisation. This is becoming increasingly important due to the environmental challenges associated with fossil resources and the global need to reduce dependence on petroleum-based processes, chemicals and materials.
6. Do you have any advice for aspiring young researchers looking to make a meaningful impact in their respective fields?
My main advice would be to stay curious and to not be afraid of stepping outside your comfort zone. During my academic journey, I moved from Brazil to Portugal, worked as a Visiting PhD student in Italy and the UK, and now I have been working in the UK since February 2025. These experiences helped me grow both personally and professionally, teaching me how to adapt, collaborate with different people from different cultures, communicate in different languages, and see research from new perspectives. I also moved into multidisciplinary research areas that were completely new to me, and those challenges became some of the most important experiences in my development as a researcher. So, I believe young researchers should be brave, persistent, and enjoy the journey!
I think the journal already provides important support to the academic community and young researchers, for example, through the Travel Award and the webinars. I believe the journal could further promote these opportunities to ensure more young researchers have access to these opportunities and are encouraged to take part in them.

International Day for Biological Diversity —“Acting Locally for Global Impact”, 22 May 2026
The International Day for Biological Diversity, a global observance dedicated to raising awareness about the importance of biodiversity, is celebrated on 22 May. The theme of the 2026 International Day for Biological Diversity is “Acting Locally for Global Impact”. Biodiversity is critical to life—healthy ecosystems provide food, clean water, climate regulation, and disease control, supporting all forms of existence on Earth. Local actions such as restoring habitats, protecting endangered species, and promoting sustainable agriculture collectively generate global benefits for nature and people. However, rapid biodiversity loss continues to undermine these vital contributions, with profound impacts on human well-being and planetary stability. Echoing the mission of protecting biodiversity for a resilient future, established MDPI journals in the Biology&Life Sciences subject serve as platforms for scientific communication, fostering collaboration and innovation in biodiversity conservation to tackle the global nature crisis.
