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

The focus of our Environmental Sciences research
Research.com’s best scientists ranking is a trustworthy
account of leading scholars from the field of
Environmental Sciences, established by means of a meticulous
examination of 166,880 scientists identified
from various bibliometric data sources. For the area of
Environmental Sciences, more than 11258 scientists were
examined.
What is D-index acceptance threshold for Environmental Sciences
The D-index threshold for approving a scientist to be
considered is set to 30 if
the majority of of their publications are in the area of Environmental Sciences. The
approval criteria for scholars to be
considered into the ranking of top researchers are based on the D-index, ratio
of the contributions made within the given discipline
in addition to the awards and achievements of the scholars. The
D-index threshold for listing best scientists is
set as an increment of 10 depending on the overall number of scientists
projected for each scientific field whilst
guaranteeing that the top 1% of leading researchers are
considered into the list. We expect a proximity of
30% or less between a scholar’s general H-index and their D-index.
Extra verification rules
As our leading goal is to make sure that only
genuine scientists are mentioned in
the ranking we realize that numbers are never
meant to be a full tool to assess the
contributions of scientists. For that reason
we manually inspect every profile and cross-correlate it against publications in a
wide range of reliable sources. Although it’s not a
factor defining a scholar’s position in
the ranking, the number of papers published in
well-known journals and conference proceedings should form a
valuable secondary implication of their contribution to research in a
given area of science. Position in the ranking is
determined by each scientist’s D-index
with the help of metrics compiled from OpenAlex and
CrossRef, which are the most trustworthy and well-established bibliometric
databases of this kind accessible to the scientific community. A
comprehensive overview of our research policy
can be found on our
methodology page.
Our goal
Our aim is to motivate scholars,
entrepreneurs and politicians
worldwide to explore where prominent experts are heading
and to give an opportunity for the entire scientific community to
get to know who the leading experts in specific
disciplines, in different countries, or even within research
institutions are.
