The lab uses data to explore sustainability in everyday life, including food, mobility, and health.
AboutAbout the lab
Advancing global sustainability through the power of data.
Long Lab studies sustainability in everyday life.
It takes an interdisciplinary approach to topics such as medicine and health, food, mobility, CO2 emissions from household consumption, and urban livability.
The lab combines environmental systems analysis, big data, map-based spatial analysis, and quantitative methods that inform policy.
Key terms
- Public health
- Efforts to protect the health of communities and society as a whole, rather than of individuals, and to prevent disease
- Carbon footprint
- The greenhouse gases emitted while a product or service is made, used, and disposed of, expressed as an equivalent amount of CO2
- Input-output analysis
- A method that organizes the exchange of goods and money between industries into a table and calculates the effect that a given type of consumption has on the economy as a whole

ResearchResearch themes
The lab studies the sustainability of daily life, spanning medicine and health, food, mobility, CO2 emissions from household consumption, and urban livability. It connects data science with the transition to a sustainable society and policy design, across food, mobility, health, and urban systems.
*Illustrative imagePublic Health in an Aging Society
The lab addresses public health challenges arising from demographic change and environmental stress. It links sustainability analysis to health risks, equity, and quality of life.
*Illustrative imageTransition to Sustainable Diets
Using recipe data and behavioral data, the lab investigates whether changing diets can reduce environmental impact while supporting nutrition and health.
*Illustrative imageAcceptable Sustainable Mobility
The lab evaluates new transportation technologies and mobility systems. The research aims to support urban mobility that is accessible to everyone, realistic, and low in CO2 emissions.
*Illustrative imageHousehold Carbon Footprints
Using environmentally extended input-output analysis, the lab calculates the greenhouse gas emissions generated by household consumption. It then identifies where emissions can realistically be reduced.
