The climate emergency is the rapidly worsening state of the Earth's climate and environment due to human activities, causing rising temperatures, more frequent and severe weather events, rising sea levels, and melting glaciers, among other effects. Urgent action is needed to address this global crisis. The carbon emission from buildings and transportation, the two important elements in an urban context, are the two culprits causing this crisis. From an urban planning perspective, I believe a rational planning urban system with good carbon, energy and accessibility performance could play a considerable role in responding to the climate emergency.

The focus of this year's design thesis is to create a zero-carbon city. As we selected the block scale to do the research, the walkable accessibility of the superblock is pivotal, and it also responds to the atelier objective of zero-carbon. Our computational tool aims to test for better performance iterations in urban carbon emission, energy and accessibility performance by inputting flexible parameters such as land use and amenity allocation, allowing users to generate and compare between outputs and eventually select the optimal one. As a result of the selection, I believe a walkable superblock can be achieved to change people's transit mode and ultimately lead to a zero-carbon future.
