Citizen participation is a recurrent and democratically important issue in the ongoing debate about climate change. However, different meanings are ascribed to citizen participation in different contexts, ranging from top-down involvement to bottom-up engagement, thus creating tension between conflicting ideals. Focusing on public engagement and its construal in different situational contexts, we explore how citizens are discursively included or excluded from participation, as various climate change discourses unfold in two forums where local needs and global concerns interact. Furthermore, we address some opportunities and barriers regarding citizen participation in climate change issues.
