172 organizations need to communicate clearly and effectively [1]. In this context, English has become the primary language of environmental science and climate diplomacy worldwide [2]. This situation is serious for more than practical reasons. Language does not simply carry information; it also shapes the way people think about problems and decide what matters most. As climate negotiations become more urgent, it is increasingly important to ask: whose voices are heard, and whose are left out, when English is chosen as the shared language of international discussion [3]? This article aims to explore these questions in a structured way. 2. THE DOMINANCE OF ENGLISH IN ENVIRONMENTAL SCIENCE The dominance of English in international scientific communication is well established. Data from the Scopus and Web of Science databases show that more than 90 percent of peer-reviewed publications on environmental topics are written in English [4]. Several structural factors help explain why this dominance has grown so strong. First, the most widely read environmental journals, such as Nature Climate Change, Global Environmental Change, and Environmental Science and Technology, publish only in English. Second, the main international environmental organizations, such as the United Nations Environment Programme (UNEP) and the Intergovernmental Panel on Climate Change (IPCC), use English as their primary working language [5]. Third, English is the official or main working language of major international environmental forums, including the annual Conference of the Parties (COP) held under the UN Framework Convention on Climate Change. The extent of this imbalance becomes clear when publication data are compared across languages (see Table 1).
