Arrange the following steps in the process of integrating local food and energy production within urban settings to create sustainable cities: A) Implement urban agriculture initiatives, B) Reduce dependency on centralized industrial systems, C) Utilize local resources for energy production, D) Achieve carbon neutrality.

To build a sustainable city, first lessen dependence on distant, industrial supply chains, which encourages local solutions. Next, start urban farms that grow food right where people live. Then, use those same local sites—like rooftops or community gardens—to generate renewable energy, such as solar panels or biogas. Finally, combine these food and energy systems to reach a net-zero carbon footprint. For example, a city might replace imported grain with rooftop gardens, power them with rooftop solar, and then use the remaining energy for heating, closing the loop toward carbon neutrality.
