| Outline of Research at the Start |
The lack of capacity to map CO2 emissions is an important barrier to mitigation action. In this research I will pilot test a method aimed at standardizing urban carbon emission mapping. I will utilize the Local Climate Zones (LCZ) classification system, that is a universal description of urban landscape, as a basis for standardizing CO2 emissions mapping, Then, I will pilot test the proposed method for several cities. The outcomes expected to help streamline urban CO2 emissions mapping that, in turn, enables an improvement/expansion of CO2 reduction activities.

| Outline of Final Research Achievements |
In this project I examined the association between different urban forms and carbon emissions. I used the Local Climate Zone (LCZ) framework to investigate the relationship between urban form and CO2 emission patterns. This framework divides urban areas into 17 classes according to their urban form characteristics. I developed the LCZ map of the three selected cities of Baltimore, Indianapolis, and Los Angeles for 2015. Next, I used the annual carbon emission data of the Hestia project to measure the per capita consumption and the amount of annual CO2 emissions in each LCZ class. Results of the project showed that, overall, carbon intensity of high-density areas with low or no vegetation is high. It was also found that per capita emissions increase with urban sprawl. But in the case of Los Angeles in particular, urban sprawl was not necessarily associated with the amount of per capita CO2 emission.

| Academic Significance and Societal Importance of the Research Achievements |
The results of thus study are important as they provide insights on the emission implications of different urban forms and can guide planners and policy makers towards creating more sustainable and resilient cities. The results offer more supports to compact city policies.
