Environmental news in Spanish media verified by the International Fact-Checking Network

In a context of growing misinformation on the internet, we analyze environmental news from the five Spanish media outlets affiliated with the International Fact -Checking Network (IFCN): Efe Verifica, Infoveritas, Maldita, Newtral, and Verificat. We propose a quantitative methodology using a sample of 217 news articles (over a period of almost 3 years) and 1,258 posts from their X (formerly Twitter) accounts over one month. We conclude that they are committed to promoting a more sustainable society, although the primary function of the created and disseminated news is explanatory or informational, with a predominant focus on "temperatures and climate change". Additionally, we observe the absence of a common dissemination strategy among these media outlets.
