As climate change becomes severe, the whole world has suffered varying devastation. Rising temperatures threaten the environment that humans rely on. Weather extremes, environmental degradation, food and water scarcity, and other issues have forced people to start a net-zero race.

Manchester has committed to achieving 'Net Zero' by 2038. One of the primary strategies to address this in city design is to create a hybrid green urban system (e.g. renewable energy system) consisting of nature and technologies.

While this aspect on its own is only a part of the solution, we propose to use patch dynamics and urban acupuncture strategy to generate a series of alternative urban green systems to develop valuable strategies toward Zero Carbon futures.

The relation of urban green systems to other systems in the city is essential to consider. Therefore, we are taking a system of systems approach to understand the cumulative performance of transport/mobility networks and urban morphology/building form in relation to the new green system network strategies.

During this time of the Climate Emergency, the role of designers in the creation of future cities has become more important than ever. One of the spatial approaches to sustainable future cities revolves around the balance between nature, the built environment and technological solutions. We developed multiple computational tools to test the reduction of CO2 emissions toward zero-carbon urban futures through the concentrated development of a hybrid green urban system (and related subsystems).
