What does it mean to build a city that works for everyone?
The world's population now exceeds 8 billion, with more than half living in cities. Cities concentrate opportunity, culture, and connection – but also inequality, pollution, and environmental strain. How we design and govern our urban environments over the next few decades will shape the trajectory of human civilization.
Green Cities is a three-week Cornell University course for high school students who want to think seriously about these questions. Drawing on urban planning, ecology, environmental justice, psychology, and policy, students learn to analyze cities through multiple lenses, and to propose research-based solutions to real urban challenges.
Students engage with primary scholarship, write an independent research essay, collaborate on a creative online exhibit, and participate in live daily discussions with an international cohort of peers. By the final week, they present original work – the kind of independent academic contribution that stands out in any college portfolio.

What students take away
Critical Thinking at a University Level
Students learn to construct arguments, recognize counterarguments, and evaluate evidence using conceptual frameworks from ecology, urban planning, and social science. This is the kind of analytical rigor expected at selective universities — practiced here, before students arrive.
Thoughtful AI Literacy
AI is integrated into the course as a thinking partner, not a shortcut. Students learn to use large language models and deep research tools to explore ideas more rigorously — building the kind of AI fluency that is increasingly expected in higher education and professional life
Independent Research and Academic Writing
Each student independently investigates a topic of their choice, reads peer-reviewed publications, and produces a research essay that integrates evidence and presents an original argument. This essay becomes a tangible portfolio piece for college applications.
Confidence in Discussion and Presentation
Daily live classes, group projects, and a final public presentation build the communication skills – and the confidence to use them – that distinguish students who thrive in university environments from those who merely attend.
A Genuinely Global Perspective
With students from the United States, China, and other countries, every discussion is enriched by diverse experiences of urban life. Students consistently report that their peers — as much as the curriculum — change how they see the world.
3 Transferable Cornell Credits
Students receive an official Cornell University transcript showing NTRES 2470 with 3 earned credits. Many US and international universities accept transfer credits from Cornell, including as fulfillment of environmental science or sustainability requirements.

Dr. Alex Kudryavtsev
PhD · Research Associate · Cornell University
Alex has been teaching Green Cities at Cornell for approximately ten years as an active researcher whose work on civic ecology and urban sustainability continuously shapes what students learn.
Students describe him as organized, approachable, and genuinely invested in their growth. He creates a classroom where high school students feel both welcomed and intellectually growing. AI tools are integrated into the course as thinking partners, helping students ask sharper questions and explore ideas with greater depth, rather than replacing the thinking itself.

A real university experience
Green Cities is an official Cornell University course with a rigorous grading standard and a transferable academic record.
-
Official Cornell Transcript. Upon completion, students receive a Cornell University transcript showing NTRES 2470 with 3 earned credits; the same document issued to any Cornell undergraduate.
-
Credit Transferability. Many universities in the U.S. and internationally accept transfer credits from Cornell. These 3 credits can satisfy distribution requirements in environmental science, sustainability, or social science at many institutions.
-
College Application Portfolio. The research essay, exhibit, and participation record from this course are evidence of real academic engagement. This course does not guarantee admission anywhere, but it demonstrates initiative, intellectual depth, and university-level capability in a way that few high school experiences can.
-
Cornell Network and Community. Students join a global community of Cornell Summer Session alumni who have gone on to universities across the U.S. and the world.
What past students say
The most well-rounded course I have ever taken. Alex teaches you to zoom out on global trends, then zoom in on your own city.
Truly interdisciplinary. I found my future pathway here. This is one of my favorite course I have taken.
Walking the streets of Shanghai today, I see green city concepts everywhere. This course changed how I see my city.
This course prepared me for college and future research. I would recommend it to my friends.
Nothing like regular school. The instructor was kind, cheerful, and communicative.
