Cities are at the forefront of energy consumption and greenhouse gas emissions, with buildings and transportation sectors contributing significantly to the carbon footprint. Our research aims to address these challenges by developing AI-based solutions that automate greenhouse gas inventories and optimize decarbonization efforts across various urban sectors.

Through the integration of machine learning algorithms, real-time data analytics, and data-driven approaches, our work enhances the precision of emissions tracking and formulates efficient strategies for reducing carbon emissions. This includes focusing on buildings' energy usage and transportation patterns. Our objective is to support the creation of sustainable, environmentally friendly smart cities by leveraging advanced technologies to drive substantial reductions in greenhouse gas emissions.

Cities account for 78% of the world’s energy consumption and produce more than 60% of global greenhouse gas emissions. Urban land use mix and density, transportation patterns, building energy usage, electrification, and renewable energy production are essential for GHG reduction. Our research focuses on testing the effectiveness of various planning policies for GHG reduction, including building energy policy, climate action plans, district energy policy, and land-based carbon sink preservation. Complementing these mitigation efforts, our ongoing work in climate adaptation planning specifically addresses extreme weather events, aiming to enhance urban resilience against intensifying risks such as heatwaves, flooding, and severe storms.

We work closely with civil and environmental engineers, developing climate change mitigation technologies such as carbon-absorbing building materials and nitrogen recycling systems. Our research focuses on the life cycle assessment of such technologies and developing planning policy solutions to support the adoption of the technologies, which could ultimately lead to expediting the decarbonization of our cities and regions.  

Land preservation has the benefits of securing parks and open space within built-up urban and suburban areas, producing food and natural vegetation for wildlife habitats, protecting source water, and sequestering carbon. Promoting compact and efficient land uses can mitigate the costs of sprawl, including dependency on automobiles and imported oil, air and water pollution, GHG emissions, and extensive infrastructure provision costs. We study the effectiveness of various growth management policies (e.g., Greenbelt, Smart Growth) to promote sustainable urban growth and land preservation, including carbon sinks in different parts of the world. 

The emergence of online platforms and big data has transformed planning and policy-making to be more accessible, inclusive, and transparent. Effective communication using online platforms can better inform our communities, make public participation accessible and inclusive, enhance planners' capacity to engage communities, and inform decision-makers to better address the needs and wants of the communities. Our research focuses on developing/utilizing online platforms (e.g., Twitter, Facebook, webpages, and apps) to collect and analyze communication data and derive useful planning implications to inform our communities, planners, and decision-makers.
