Tu Huella de Carbono (Your Carbon Footprint) is an application created in collaboration with the Comunidad #PorElClima, an Spanish initiative involving different people and entities that promote the transition from commitment to action to tackle climate change. Its goal is reducing your ecological footprint through the game following the advices that will appear on the screen once you defeat the minions who try to drown you.

The dynamics of the game is quite simple (with the attached video you will understand it perfectly):

  • In the game, you adopt the role of a flower that has to move inside a house looking for sources of carbon emissions that contribute to climate change. These polluting sources are manifested through a few green fumaroles that can emanate from the different household appliances or from objects located in the different rooms.
  • Once you arrive near the emitting source, it will appear an icon in the center of the screen that will transport you to a new scenario where you have to defeat the so-called CO2 minions that will appear. To finish with them, you just have to aim them and press the Flash button until they disappear (the number of minions that you have to defeat increases as you advance in the game). Remember to control your life bar.
  • Once exterminated, a congratulation message will appear on the screen showing how a change of habits has a favorable impact on reducing your CO2 emissions (for example, the reduction in the use of plastic bags shown in the attached image).

To finish the game you must face the different missions until you complete the green bar that appears at the top.

According to a study cited by CityLab in February 2016, the main sources of man‑made greenhouse gas emissions are industry, commercial, transportation, residential and agriculture. From a particular point of view, the last three mentioned sources have a special incidence. Although the more important impact is caused by transportation, all the changes in personal behaviour to reduce the carbon footprint are welcome. And a lot of them are easier to carry out than you think, with little actions, such as adjust correctly the fridge temperature or reduce the use of plastic bags, that you can perform and share with your family.

The application Tu Huella de Carbono makes it possible to know what these everyday actions are. Although it does not exclude any age range, it may be especially attractive to increase awareness among young people about climate change from an individual perspective. The game is enjoyable, well designed and agile, although it may be difficult at first to understand its operation, so it might be interesting to include a small tutorial. Also, it should be noted that the tests have shown that the use of devices with a large screen (iPad vs. an Android mobile) facilitates the gameplay of the application.
