The position of each scientist in the ranking is established based on their D-index (Discipline H-index), a specialized metric that considers only papers and citation counts relevant to the examined discipline—in this case, Environmental Sciences. This ensures that rankings reflect scholarly impact and productivity within the specific research area, fostering discipline-focused assessments.
Scope of Research and Criteria for Inclusion
In developing the ranking, 279,971 scientist profiles were examined across all disciplines using a variety of bibliometric data sources, with a focus on Environmental Sciences where 3,XXX scientists were identified (please note the placeholder if the number is unavailable). Researchers qualified for inclusion in the ranking by meeting a minimum D-index threshold of 30, ensuring a high level of disciplinary impact. Additionally, the majority of a scientist’s tier publications had to be firmly situated within the Environmental Sciences domain to guarantee thematic relevance.
A scientist’s awards and achievements specifically in Environmental Sciences were also considered to provide qualitative validation to the quantitative D-index metric. The threshold of the D-index is dynamically adjusted by increments of 10 depending on the estimated total number of scholars in each discipline, while also guaranteeing inclusion of the top 1% of leading experts. Furthermore, to ensure coherence between overall scientific influence and discipline-specific impact, only researchers with a proximity of 30% or less difference between their general H-index and D-index were considered.
Verification and Methodological Rigor
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of scholarly output or quality, the Research.com team performed additional verification practices to ensure the credibility and accuracy of the ranking. All scientist profiles were manually verified and cross-correlated against publications in a diverse range of trustworthy academic sources. This meticulous manual curation mitigates inaccuracies, disambiguates author identities, and contextualizes bibliometric signals.
While not directly influencing the rankings, the volume of publications in prominent journals and conference proceedings serves as a valuable secondary indicator of a scientist’s contribution to the Environmental Sciences community. The ranking's core metric—the D-index—is calculated using citation and publication data sourced mainly from OpenAlex and CrossRef, which are globally recognized as among the most authoritative and comprehensive bibliometric databases accessible to the research community.
