The 2nd edition of Research.com ranking of the best researchers in the
field of Environmental Sciences relies os data
derived from various data sources including OpenAlex and
CrossRef. The bibliometric data for evaluating the citation-based metrics were
acquired on 21-12-2022. Position in the ranking is based on a scientist's
D-index (Discipline H-index), which only includes
publications and citation data for an examined discipline.

The range of our Environmental Sciences research
Research.com’s best researchers ranking is a reliable
list of leading scholars from the field of
Environmental Sciences, created using a meticulous
examination of 166,880 scholars determined
from multiple bibliometric data sources. For the field of
Environmental Sciences, as many as 11258 researchers were
analysed.
What is D-index inclusion threshold for Environmental Sciences
The D-index threshold for including a researcher to be
evaluated is set to 30 if
the majority of of their publications are in the discipline of Environmental Sciences. The
acceptance requirements for scholars to be
considered into the ranking of top scientists are based on the D-index,
ratio of the publications made within the specific
area plus the awards and achievements of the
scientists. The D-index threshold for considering best
scientists is set as an increment of 10 depending on the total number of
scholars estimated for each
area od study whilst ensuring that the top 1% of
leading scientists 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 practices
Because our primary aim is to guarantee that only
genuine scientists are listed in
Research.com ranking we are aware that raw data are never
meant to be a complete measure to assess the
contributions of scholars. This is why
we manually inspect every profile and cross-correlate it against publications in a
wide range of trustworthy sources. While it’s not a
metric impacting a researcher’s position in
Research.com ranking, the quantity of papers published in
well-known journals and conference proceedings should form a
credible secondary signal of their contribution to research in a
selected discipline. Position in the ranking is
determined by every scholar’s D-index
with the help of metrics compiled from OpenAlex and
CrossRef, which are the most trustworthy and well-known bibliometric
databases of this kind available to the research community. A
thorough definition of our research process
can be found on our
methodology page.
Our goal
Our objective is to inspire scholars,
companies and politicians
worldwide to examine where prominent experts are heading
and to offer a way for the whole research community to
get to know who the leading experts in specific
areas of study, in different countries, or even within research
institutions are.
