Contrasting the climate change emergency represents one of the major challenges of modern times. Knowing how people represent ecology-related phenomena is crucial to inform interventions aimed at promoting more effective pro-environmental behaviors. Despite this, literature on the topic is still scarce. To fill this gap, we asked 340 participants to rate 200 concepts—among which Ecological (N = 50, e.g., deforestation)—on numerous semantic dimensions (N = 39), drawing insights from the literature on conceptual organization. A Principal Component Analysis on our dataset revealed the presence of three major components explaining overall the variability of our set of concepts. Interestingly, Ecological concepts had a major role in all of them. Indeed, when compared to other conceptual categories—both related (i.e., Natural—e.g., water—and Geographical/Geopolitical—e.g., ocean, city) and not related (i.e., Technological—e.g., Internet) to the green domain—they figured among the most abstract (Component 1), impacting our political, social, and personal spheres (Component 2), scientific, emotionally charged, and evoking sensorimotor experiences (Component 3) concepts. Overall, our study has a threefold relevance. On a theoretical side, it can contribute to enriching theories on concepts by investigating a new semantic domain that jeopardizes the concrete-abstract dichotomy; on a scientific side, it might broaden categorization research by providing semantic norms for new conceptual domains (the TECo Database); on a societal side, it can enhance politics on these timely themes.
