Catalyse action: Lifestyle test

Are you a threat or an opportunity? On the way toward the 1.5-degree climate target, knowing your own carbon footprint is the first steppingstone on the way to reducing it. Lifestyle test is an easy carbon footprint calculator that helps individuals understand how to live more sustainable life.



Our carbon footprint calculator, Lifestyle test, helps individuals assess the environmental impacts of their lifestyles. By answering 27 questions, each respondent can see the size and composition of their carbon footprint and how it compares to the average test taker.

We wanted to create a test that is accessible, as easy to complete as possible and that could even encourage taking action to help the climate for perhaps the first time.

The questions and calculations of the lifestyle test are based on environmental calculations and the consumption of the average Finnish person, as a result of which calculations must be examined separately for each country when introducing the test for local use.

It takes approximately three to five minutes to complete the test. The lifestyle test collects no personal data from those taking the test, but the owner can export the results distribution to learn more about the respondent’s current lifestyle. The test is responsive and fully scalable on every platform, both mobile and desktop.

The lifestyle test is best accompanied by 100 Smart everyday choices list, which shows a selection of tips that will help save money or improve quality of life while reducing carbon footprints. See the add-ons.
