On May 5, 2022, Research.com released the 1st edition of the annual ranking for top scientists in the area of environmental science. This list of leading scholars is designed to offer the academic community more visibility and exposure to the influential research contributions made by those at the forefront of environmental science.

What is more, we hope it will inspire researchers, decision-makers, and entrepreneurs around the world to find out where leading experts are heading. It is a great opportunity for all of us to learn who are the leading experts in different research areas, in different countries, as well as within different universities and research institutions.

For the 2022 edition of the ranking, more than 9,100 scientist profiles on Google Scholar and Microsoft Academic Graph have been examined with several indicators and metrics reviewed in order to consider each scientist’s inclusion in the ranking.

The h-index threshold for approving a scholar to be considered was set to 30 if most of their publications were in the field of environmental science. The inclusion criteria for scholars to be considered into the ranking of top scientists are based on the discipline h-index, the proportion of contributions made within the given discipline in addition to the awards and achievements of the scientists. 

The key findings for the 1st edition of top environmental scientists ranking

  • Scientists from the United States dominate the list with 498 scholars included in 2022 which represents 49.8% of the whole environmental scientists ranking.
  • The other leading countries with leading positions in the ranking are the UK (80 scientists or 8%), Germany (66 scientists or 6.6%), China (60 scientists or 6%), Australia (36 scientists or 3.6%), and Switzerland (35 scientists or 3.5%)
  • Only 4 out of 10 scientists in the top 1% are from the United States.
  • In the 2022 edition of our ranking, the US National Center for Atmospheric Research is the leader, with 28 scientists affiliated with that institution included in the ranking.
  • The top-ranking scientist in environmental science is Daniel J. Jacob from Harvard University with an h-index of 174.
  • American universities constitute 80% of the 10 top leading institutions with the only other represented institutions being based in China, and Germany.
  • The highest cited scientist is John H. Seinfeld from the California Institute of Technology with 121,964 citations.
  • The average H-index for the top 1% of scientists is 151 against an average of 78 for all 1000 scientists included in the ranking.
