| Outline of Annual Research Achievements |
To examines potential linkages between urban form and carbon dioxide emission patterns, I have relied on the Local Climate Zones (LCZ) classification system. I developed the LCZ map for pilot cities including Los Angeles considering data availability. I have linked the emission data to the LCZ map to estimate per hectare and per capita emissions of each LCZ type. Results show that, in most cases, different LCZ types feature similar per capita emission patterns. This is, particularly, the case for commercial emissions. In terms of residential buildings, however, LCZ NO. 9 that refers to sparsely built development type exhibits significantly higher per capita emissions. This support common arguments regarding the environmental footprints of urban sprawl.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
I am now collaborating with colleagues from the united states who have provided me data for several major cities. This access to high-resolution data has made it possible to advance the project quite smoothly. Specifically, I have now access to Local Climate Zones maps for several cities and can link residential and transportation emissions to different Local Climate Zones types.

| Strategy for Future Research Activity |
In the third year, I will continue testing the method in at least three more cities. At the moment, I plan to test it in Indianapolis, Salt Lake City, Baltimore, and, if data is available, Hiroshima. Also, even though the initial results showed that a better understanding of the effect of urban form on emission and per capita throughout the cities could be reached by utilizing the LCZ method, but energy consumption in different LCZs is not only affected by urban form. It also depends on other parameters like economic and social factors, and also the building’s operation mode. Therefore, I will also try to adopt mechanisms to take account of socio-economic and environmental factors that are necessary for better understanding of emission dynamics using the LCZ framework.

| Causes of Carryover |
Some of the budget was supposed to be used for travel to attend international conferences. This was not possible due to mobility restrictions that were implemented to control the spread of COVID-19. For the next year, the budget will mainly be used for three purposes: 1- wages for the activities or three Research Assistants (RAs). This account for about 75% of the remaining budget. 2- Some budget will be used to publish up to three papers (reporting some of the outputs) in open access journals. 3- Some additional software and hardware tools may be purchases if needed.
