What is DELI Calculator?
DELI ("fooD rEcipe environmentaL Impact") Calculator is a web application designed to provide comprehensive, quantitative sustainability assessment of food recipes. Our mission is to empower individuals, chefs, and food businesses to make informed decisions about their food choices by understanding their environmental footprint.
Developed by researchers at the Norwegian University of Science and Technology (NTNU), DELI Calculator uses scientifically robust data to estimate the carbon emissions, water usage, and land use associated with food ingredients and recipes.
More information about the app architecture and development can be found via our GitHub repository: DELI Calculator GitHub Repository
How DELI Calculator Works

Paste a recipe URL or manually input ingredients to analyze the environmental impact of any dish.
Data Sources
Our calculations are based on the FABIO database, and the Poore and Nemecke ingredient classfication, ensuring scientifically accurate results.
Impact Metrics
Get detailed breakdowns of biodiversity impacts, CO₂ emissions, water usage, and land use for the entire recipe, including how these impacts are distributed across countries worldwide.
Why Food Environmental Impact Matters
The food system is responsible for approximately 26% of global greenhouse gas emissions, 70% of freshwater use, and 50% of habitable land use. By understanding the environmental impact of our food choices, we can collectively make a significant difference in reducing our ecological footprint.
DELI Calculator helps bridge the gap between scientific knowledge and everyday cooking decisions, making sustainability accessible to everyone.

Frequently Asked Questions
Our calculations are based on two comprehensive datasets: the FABIO database (GitHub) and the Poore & Nemecek ingredient classfication, which are among the most scientifically robust databases for food environmental impact. However, it's important to note that these are estimates based on average values, and actual impacts can vary based on specific farming practices, transportation methods, and other factors.
