Challenges: In the real world

Quick Facts 

  • 1 kilogram of pork is responsible for the same amount of CO2 output as 80 kilograms of potatoes

  • For the production of 1 kilogram of beef, 15.4 kilograms of CO2 is emitted, compared to 0.7 kilograms of CO2 for lentils

  • Food and nutrition is responsible for around 30 percent of the environmental impact 

One of the largest greenhouse gas contributors is the agricultural industry, especially livestock. We as consumers have the power of choice.  We steer the demand of products and company offerings. 


One of the easiest ways to contribute towards positive change in this manner is to eat less meat. A simple choice between animal or vegetable foods, can and will have a tremendous impact on our environment. Many alternative sources of protein are popping up from insects to plant based meat.  As with many things we consume, we simply enjoy the “thing” itself without thinking what consequences this may have if everyone consumed the way that we do. It is crystal clear now, however, that the result is a warming and suffering planet.

According to WWF Switzerland, approximately one third of the environmental impact of consumption in Europe is due to our food.  Everything revolving around livestock is particularly harmful to the environment: it is very resource-intensive and causes significantly more greenhouse gas emissions than the cultivation of plant-based food products. Secondary by a long shot is packaging, transport, storage, preparation and disposal. 

For example, the footprint of the diet of an average Swiss reduces by 24 percent when switching to a vegetarian diet. When eating vegan, the figure is as high as 40 percent. Regional products only improve the footprint in this area by about 4 percent. The conversion from animal to plant nutrition can thus reduce the nutritional footprint ten times more effectively than the conversion from foreign to Swiss products.

On average, animal proteins are responsible for half of the nutritional environmental pollution. The fewer of them, the better for the climate, for our environment, thus for our livelihoods. A vegetarian dish pollutes the climate on average three times less than a dish with meat. Vegan dishes are even better. If some any meat-related products should be on the table regardless, organically produced products are preferable - which labels are particularly recommendable, you can find out in our

Bonus: The Shower Challenge


Quick facts

  • Mexico City has the 6th largest metropolitan population in the world, with over 20 million inhabitants. Every morning, 10 million of those will start their day with a shower, wasting 10 litres of water waiting for the shower warm.

  • 100 million liters of water drained well and truly is an astronomical sum. Imagine if there were to be a collective effort to put this water to good use.

Mexican artist Pedro Reyes tackled the issue in his 2005 project "Zink Sink".

"This device is a funnel that collects this water into a pitcher so that it can be used for other purposes".
We were captivated by the issue, and the underlying sentiment behind the idea, and formed our first challenge around this issue.
