On April 17, 2023, Research.com published its second annual report on the top scientists in the field of environmental science. This year, we release an updated list that aims to contribute to increasing the online visibility of researchers, professors, and academics who actively share their knowledge in this community.
Moreover, by publishing an annual report of the most active scientists in environmental science, we can also make it easier for other researchers, businesses, and organizations to network with environmental scientists so that they can collaborate on their projects. The report provides an opportunity for people to learn about the leading experts in various research areas, countries, universities, and research institutions.
To compile the ranking, our research team evaluated more than 11,000 scientist profiles on OpenAlex and CrossRef, and other bibliometric sources. We used various indicators and metrics, including the proportion of contributions made within the given discipline, as well as the awards and achievements of the scientists. Scholars with a D-index of 30 or more in environmental science were included in the ranking, provided that most of their publications were in this field.
Currently, urgent environmental concerns encompass a range of issues such as pollution, global warming, overpopulation, waste management, ocean acidification, biodiversity loss, deforestation, depletion of natural resources, and ozone layer depletion. Moreover, there are growing apprehensions about water scarcity, air pollution, and the detrimental effects of toxic chemicals and plastic on marine life and the environment.
As of 2023, the most significant environmental challenges that need immediate attention and action include climate change, deforestation, plastic pollution, and biodiversity loss. Addressing these issues is crucial to minimize their adverse impact on the planet and its inhabitants.
Environmental scientists are working round the clock to find solutions to these pressing issues. For example, NASA scientists developed a new method to measure isoprene, a chemical compound associated with poor air quality. With this new method, scientists could improve databases and find ways to help local communities improve air quality.
Another discovery is about the toxic effects of sunscreen chemicals on water and marine life. Chemicals found in some sunscreens like nano-Titanium dioxide, Oxybenzone, and 4-Methylbenzylidene camphor may wash off and enter waterways, which in turn could cause reproductive problems and physical defects in marine animals.

Scientists affiliated with universities in the United States dominate our 2023 report. A total of 468 scientists come from the U.S. This number is down from last year's 500 scientists.
The second country with the most leading scientists is The United Kingdom. There are 92 scientists coming from the U.K., twelve more compared with last year.
Keeping its third place is Germany, with 70 scientists this year versus 66 last year.
The next leading countries have maintained their positions, too, such as China with 62 scientists, Australia (43), Switzerland with 36 scientists, Canada (35), and France (30). Rounding up the top 10 countries in the field are the Netherlands (24) and Spain (23).
Please note that the country associated with a scientist is based on their affiliated research institution, according to MAG, not on their actual nationality.
In the 2023 report, the National Center for Atmospheric Research is once again the leader, with 25 scientists affiliated with that institution.
The top 2 and 3 positions also remain the same with the U.S. National Oceanic and Atmospheric Administration and the Goddard Space Flight Center. These institutions have 20 and 18 scientists, respectively.
American universities and institutions constitute 65% of the top 20 leading institutions, with the other ones representing China (Chinese Academy of Sciences), Switzerland (ETH Zurich), and Germany (Max Planck Society).
Other research institutions in Europe in the top 20 include the Spanish National Research Council, the University of Reading, and the University of Exeter.
To continue providing quality education, universities have opened their campuses to online learners. Some of the best universities now offer online programs that lead to the degree that students can complete entirely online.
Against this backdrop, online universities have the potential to greatly strengthen research in the field of environmental science. Aside from the most obvious advantages like flexibility and convenience, online universities can also provide researchers with access to a wider range of research locations, including remote and hard-to-reach areas. This can lead to more comprehensive and diverse data collection, which can enhance research outcomes.
Additionally, online universities can facilitate collaboration across different geographic locations. Researchers from different parts of the world can work together without borders and share information, leading to the development of more comprehensive and innovative research approaches.
Moreover, online universities can provide researchers and students with access to a wide range of resources, including databases, journals, and other online tools. This can help researchers to stay up-to-date with the latest research findings and to access resources that might not be available at their physical location.
