The urban response to the climate crisis has culminated in a diverse set of sustainable city concepts. From eco-cities to smart green cities, urban green initiatives are primarily focused on governance or technological solutions. I propose using a hybrid perspective of governance, metabolic and machinic to create a deeper understanding of urban green initiatives. My research looks at the possibility and potential for these urban policies and greening initiatives to create deep changes that redefine the relationship between city infrastructures, people and nature in order to achieve environmental sustainability. At present I am carrying out my fieldwork in Singapore through qualitative and creative mixed methods.
