Twitter use during COP21

Communication via social media is an important channel of information and interaction during events like the climate conference. In this project, we focus on Twitter and analyse how different actor groups have used the service during COP21.

In a first part, we want to know if physical presence at the COP impacts scientists’ Twitter use. Using geolocated tweets, we compare the Twitter use of scientists who were present at the conference to those who were not. Combining automated, quantitative and qualitative content analysis, the study shows how scientists participating in the conference provide live reporting and form a transnational network.

In a second step, we also look at other actors such as journalists, politicians and members of civil society organizations and their interactions via Twitter.
