The 2nd edition of Research.com ranking of the best scientists in the
field of Environmental Sciences was created using data
combined from multiple data sources including OpenAlex and
CrossRef. The bibliometric data for devising the citation-based metrics were
collected on 21-12-2022. Position in the ranking is based on a scholar’s
D-index (Discipline H-index), which takes into account only
publications and citation values for an examined discipline.

The range of our Environmental Sciences research
Research.com’s best researchers ranking is a trustworthy
account of leading scholars from the field of
Environmental Sciences, created using a thorough
study of 166,880 researchers discovered
from multiple bibliometric data sources. For the area of
Environmental Sciences, as many as 11258 researchers were
examined.
What is D-index approval threshold for Environmental Sciences
The D-index threshold for accepting a scientist to be
examined is placed at 30 if
the majority of of their publications are in the area of Environmental Sciences. The
acceptance criteria for scientists to be
considered into the ranking of top scientists are based on the D-index,
ratio of the contributions made within the selected
field of study in addition to the awards and achievements of the
researchers. The D-index threshold for including best
scientists is set as an increment of 10 depending on the total number of
researchers projected for each
area od study whilst ensuring that the top 1% of
leading researchers are considered into the ranking.
There should be a proximity of 30% or less between a scientist’s
general H-index and their D-index.
Additional verification practices
As our primary mission is to guarantee that only
actual scholars are listed in
the ranking we realize that numbers are never
supposed to be an absolute tool to assess the
output of researchers. For that reason
we manually verify every profile and cross-correlate it against publications in a
varied range of trustworthy sources. While it’s not a
element impacting a scientist’s position in
Research.com ranking, the number of documents published in
major journals and conference proceedings should form a
reliable secondary signal of their contribution to research in a
specific area of science. Position in the ranking is
established using each researcher’s D-index
using data compiled from OpenAlex and
CrossRef, which are the most prominent and well-established bibliometric
databases of this type available to the research community. A
detailed overview of our research process
can be found on our
methodology page.
Our goal
Our aim is to inspire researchers,
companies and administrative bodies
around the world to investigate where prominent experts are heading
and to provide a way for the entire scientific community to
get to know who the leading experts in specific
areas of study, in various countries, or even within research
institutions are.
