Final answer:
Urban planning can combat greenhouse gas emissions by increasing walking and decreasing driving, which involves enhancing public transport and creating pedestrian-friendly urban designs. Energy-efficient buildings and sustainable practices also contribute to reducing emissions.
Step-by-step explanation:
Urban planning can decrease greenhouse gases when cities are designed to increase walking and decrease driving. This strategy involves creating more pedestrian-friendly spaces, prioritizing public transportation over private car use, and implementing urban designs that reduce the need for long-distance travel within cities. Measures such as promoting bicycling, improving public transit systems, and developing compact cities can lead to a significant reduction in emissions from the transportation sector, which is a major contributor to greenhouse gas emissions.
Moreover, urban planning can also involve the incorporation of green spaces like gardens, but to effectively reduce greenhouse gases, the focus must be on transport and energy usage. Architects and planners are working on designing buildings and communities that are energy efficient and sustainable, leading to the creation of net-positive houses, which produce more energy than they consume. The technology to reduce carbon footprints exists, but it requires the support of robust governmental policies and climate-friendly technological advancement.
