This terminology has been developing rapidly since the mid- XIXth century, particularly through the adoption of numerous concepts from related scientific disciplines and from everyday language. Nowadays more and more new words and expressions appear, creating difficulties in compiling specialized dictionaries. Scientific interest in this area is driven by the growing attention of leading countries to environmental protection and the rational use of natural and energy resources. Environmental issues cannot be resolved by a single country alone, as most global challenges require active international cooperation and coordinated action, increasing the demand for high-quality translations of relevant materials. The constant emergence of new environmental terms necessitates their classification, as well as the study of the sources and the formation of neologisms. The aim of this study is to determine the structural and semantic characteristics of German and English terms in the field of ecology and energy efficiency. The authors used such research methods as continuous sampling, structural and semantic analysis, descriptive and comparative methods. Material for the study was selected from English-Russian and German- Russian environmental dictionaries, as well as from texts published on specialized websites in English and German devoted to ecology and energy efficiency. The analysis revealed that the majority of sampled terms denote environmental factors and energy-related concepts and phenomena. The source of new terms in both languages is common vocabulary, which undergoes a process of terminologization and metaphorization. There are also borrowings from other languages and neologisms. The German language borrows ecological terms predominantly from English. The active use of compounding as a means of word formation in German ensures the brevity and conciseness of the German terms, unlike the English ones.</p></abstract><trans-abstract xml:lang="en"><p>Der Artikel untersucht die Terminologie im Bereich der Ökologie und der Energieeffizienz. Dieses Terminologiesystem bildet sich intensiv seit Mitte des XIX. Jhs, und zwar durch die Entlehnung mehrerer Begriffe aus verwandten Wissenschaftsdisziplinen und der Alltagssprache. Heute wächst es stetig und erweitert sich um neue Begriffe und Ausdrücke, was die Erstellung der Fachwörterbücher erschwert. Das akademische Interesse an diesem Thema wird durch die zunehmende Aufmerksamkeit führender Länder für Naturschutz und die nachhaltige Nutzung von Natur- und Energieressourcen befeuert. Umweltprobleme lassen sich nicht von einzelnen Ländern allein lösen, da die meisten globalen Herausforderungen eine aktive internationale Zusammenarbeit und koordiniertes Handeln erfordern, was den Bedarf an qualitativ hochwertigen Übersetzungen von Materialien zum jeweiligen Thema erhöht. Die ständige Entstehung neuer Umwelttermini erfordert deren Klassifizierung, die Erforschung ihrer Bildung und die Erfassung der Entstehung von Neologismen. Das Ziel der Studie ist es, die Bestimmung der strukturellen und semantischen Merkmale deutscher und englischer Termini im Bereich Umwelt und Energieeffizienz. Die Autoren haben dabei solche Methoden wie deskriptive, komparative, der kontinuierlichen Stichprobe, der strukturellen und semantischen Analyse verwendet. Das Material für die Studie bildeten Termini, die aus englisch-russischen und deutsch-russischen Umwelt-Fachwörterbücher sowie aus Texten ausgewählt wurden, die auf fachspezifischen englisch- und deutschsprachigen Websites zu den Themen Umwelt und Energieeffizienz veröffentlicht wurden. Die Analyse hat gezeigt, dass die Stichprobe vorrangig Termini zur Bezeichnung von Umweltfaktoren, Konzepten und Phänomenen im Bereich der Energieressourcen aufweist. Die Quellen neuer Termini in beiden Sprachen sind der allgemeine Wortschatz, der Prozessen der Terminologisierung und Metaphorisierung unterliegt, sowie Entlehnungen und Neologismen. Die Wortentlehnung ins Deutsche erfolgt vor allem aus dem Englischen. Die im Deutschen aktive Wortzusammensetzung als Wortbildungsverfahren führt zu kürzeren und prägnanteren Termini als im Englischen.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>term</kwd><kwd>terminology system</kwd><kwd>word formation</kwd><kwd>semantics</kwd><kwd>language</kwd><kwd>ecology</kwd><kwd>energy efficiency</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Terminus (Fachbegriff)</kwd><kwd>Terminologiesystem</kwd><kwd>Wortbildung</kwd><kwd>Semantik</kwd><kwd>Sprache</kwd><kwd>Ökologie (Umwelt)</kwd><kwd>Energieeffizienz (Energiesparen)</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Paderina T.S.
