Planetary sustainability has emerged as a challenging phenomenon today. Though there have been various discussions and deliberations in reducing carbon footprints and adapting green practices, things are not really moving in the right direction. However, the emergence of many new green practices cannot be ignored at the same time. Climate change is real and possesses many unexpected disasters to happen if not addressed on time. The researchers have claimed already that this threat needs to have a collective response rather than waiting for some specific governments to act. This chapter attempts to make an account of green practices around the globe and explores the way internet of things and digital marketing are playing or can play in the propagation of the same. This study makes an account of possible best practices and the way they have been promoted in the recent past. This will have an implication on the social scientists, ecologists, digital marketers, environment activists, and government bodies.
