Comparative studies on climate change communication are fundamental to understanding how societies undertake and react to this global topic (Kohn, 1987). Social media in this context helps to sensitize and spread the already known importance of the phenomenon by trying to minimize the distance between the nation’s policies and societal consciousness. This research aimed to analyze three official Twitter accounts of Ministries focusing on COP26, a global event of fundamental importance concerning renewable energy, the policies of which must be followed to combat the crisis. The research was divided into 3 parts: pre-COP26, which analyzed the Twitter accounts 1 week before the event; during COP26 from October 30th to November 13th, 2021; and after COP26 until November 20th to see the change that this global event had on the three countries. As a result, it was noted that Italy and Turkey used Twitter ineffectively, while Norway, being more active, managed to reach a greater audience. This research illustrated the fact that, although the crisis is global, states work nationally.
