Mega-structures and sport mega-events have been attractions in many mega-cities representing their identity to the rest of the world. Such phenomenon has also taken place in Jakarta by the existence of the newly erected Jakarta International Stadium and the recently held Formula E and both have gained attention and stimulated conversations in Indonesia. So have both been known as a green stadium and a green race. Integrating sustainability to urban development has been a global trend and Jakarta attempts to take advantage of such trend to create branding. This research aimed to describe the rationale of greening the stadium and race by the Jakarta regional government within its city branding policy. This research employed the qualitative method and descriptive analysis in addition to the concept of para-diplomacy and city branding. This research found that both green stadium and race were utilized as symbols or promotional value to promote green development in the city. City branding by the Jakarta regional government was a diplomatic practice bringing a message about the city transformation to be a green and global city. This paper provides a perspective that city branding is para-diplomacy itself or one form of para-diplomacy practices. This paper argues that through city branding, cities should be able to not only widen their specific needs locally but also pave their global role in addressing the global challenges like climate crisis. This paper benefits those who are interested in or are studying today city para-diplomacy and global urban politics.
