Worldwatchers Climatecompass

The app produced by the climate company worldwatchers is uncluttered and has an appealing design. One pleasing aspect is that you don’t have to create a user account.

First of all, your personal carbon footprint is calculated, based on data such as housing, nutrition, mobility, shopping, leisure, holidays, digital life and public emissions. This is comprehensive and pleasingly detailed: you can also select car sharing under “Mobility”, for example. Your total CO2 consumption is compared with the average in Germany, which worldwatchers puts at 11.2 tonnes per year.

The app also invites you to take on challenges and collect “climate points”: at level 1 you’re challenged to go on a vegetarian diet for three days or limit your streaming time to four hours a week, for instance. For each challenge, you get brief, interesting background information on the climate impact (for example: did you know that two hours of streaming generates 1.2 kg of CO2 emissions?). As you you collect points, you access higher challenge levels.

And if that’s not enough, the app also enables you to join the climate protection campaign “klimathon”. Finally, a barcode scanner is integrated that allows you to look up the carbon footprint of individual products – at least in theory: unfortunately there are many items it doesn't recognise. Another weak point is the input menu for your CO2 footprint: it is simply structured but results in confusing choices due to the slider function.

AdvantagesDisadvantages
  • No user account
  • Clear/appealing
  • Detailed questionnaire
  • Innovative ideas with challenges
  • Background information
  • In English
  • Selection menu slightly confusing
  • Slider not ideal for precise entries (e.g. number of kilometres)
  • Not all functions are usable

Overall rating: 4 out of 5 stars

Klima – live carbon neutral

Another recommended app is called “Klima – live carbon neutral”: it is in English and comes with a very nice layout featuring animated pictures.

The questionnaire on your CO2 consumption starts with your flight habits and covers nutrition, mobility, shopping habits, household size and electricity. The questions are less precise than in worldwatchers climatecompass. The response options are also more limited, and there is no background information.

But one thing we think is cool is that your footprint is displayed graphically, so you can see at a glance in which areas of your life you’re generating most CO2. Your result is compared to the Swiss average of 4.8 tonnes. Here the app gives you an additional option: it enables you to offset the CO2 you’ve produced. You can do this by supporting tree planting projects, solar power projects or the installation of “clean” stoves (no deforestation required) in various countries, for example Offsetting one tonne of CO2 will cost you EUR 10. If your footprint is within the Swiss average, this means a donation of just under EUR 4 per month. To activate the payments you have to create a user account, but you can cancel any time you like. 

Advantages

Disadvantages

  • No user account
  • Integrated CO2 offset function
  • Uncluttered
  • Appealing look
  • In English
  • Questionnaire is not very differentiated
  • No background information
  • No additional functions

Eevie

Eevie is an English-language app that allows you to get started without a profile or login: the only thing it asks you to enter is your country of residence, for comparative purposes. Its design is clear and attractive.
The app bases your footprint on your living space, your road mileage, your meat consumption and your purchase of consumer goods. Unfortunately, the questionnaire is not very detailed: For example, only road mileage can be entered under the “Travel” options – car sharing and the like are entirely lacking, and your electricity consumption is not even mentioned.
 

Eevie then breaks down your footprint according to the sources. One point we like is that the app suggests specific “new habits” that can make your everyday life more climate-friendly: replace red meat with fish or plant-based alternatives, for example, or find out what’s meant by a zero-waste lifestyle. The app tracks your new habits by asking you questions, while keeping a record of how much CO2 you're saving at the same time. Eevie also provides background information, statistics, links to media articles and practical tips such as meat-free recipes.
 

The “Offset” category also allows you to offset the CO2 you generate by donating to selected projects. What is more, you can hook up with friends and get involved in the community.

AdvantagesDisadvantages
  • No user account
  • Diverse functions incl. CO2 offsetting
  • Lots of background information
  • Links to other websites
  • Appealing design
  • In English
  • CO2 calculator not very comprehensive
  • Questionnaire not detailed enough

Overall rating: 4 out of 5 stars
