Before you start

FOOTPRINTCALC provides a quick and efficient way to calculate a carbon footprint or life cycle assessment. However, a basic understanding of life cycle assessment is required for understanding what data needs to be input and how the results must be interpreted. An introduction to performing an LCA can be found on the website of Sustainability Impact Metrics, the author of the database included in FOOTPRINTCALC. An alternative is studying the freely accesible guidance provided by the Greenhouse Gas Protocol product standard.

Sustainability claims are increasingly coming under scrutiny. FOOTPRINTCALC is a great tool for performing hotspot analyses and LCA screenings for internal use. If you want to communicate your results to external stakeholders, an independent review of the results, assumptions, and calculations can be required by different normative frameworks such as the GHG protocol or the ISO 14040 family.
Lifecycle analysis


Includes database

FOOTPRINTCALC includes the open access Idemat 2023 Rev A database developed at Delft University of Technology. The database contains impact factors for around 900 materials, 80 production processes, electricity country mixes, transport, and over 200 end-of-life treatments. The database also allows for calculating eco-costs, a measure to express the costs of preventing eco-burdens. Additional open access environmental databases can be found at

Easy to use

FootprintCalc's interface
By using drop-down menu's you can easily select impact factors to calculate environmental impact. If an impact factor cannot be found in the database you can include your own custom impact factors.

Great insights

The results of the calculations are displayed per life cycle stage. Besides the carbon footprint, FOOTPRINTCALC can calculate results for many different environmental impacts using eco-costs, ReCiPe2016, EF3.1, and CED methods. Processes can be sorted on biggest impact, allowing for a quick hot-spot analysis.

Scenario editor

FootprintCalc's detailed results
FOOTPRINTCALC has a dedicated module for calculating design scenarios. This allows you to readily ascertain what the reduction potential is of design scenarios such as using recycled materials, changing production methods, or adopting circular business models.


Below you can find a video tutorial for FOOTPRINTCALC. The video explains how to model a product in the calculator, as well as how to use the design scenario module (starting at 15:00). The video is hosted on Vimeo and does not track and/or use cookies. Note: the video is based on version 1.0. The current version 1.2 has some additional functions that are not covered in the video. All basic functionality is the same. We intend to update the video shortly.
