CarbonDelta made it to be a part of Zürich‘s climathon 2017 sponsored by energie360°, City of Zürich, Climate-KIC and ImpactHub Zürich. At Climathon Zürich developers, entrepreneurs, technical experts and students worked together to find new solutions or develop existing ideas on different challenges during a 24 hour period. In a vibrant atmosphere supported by experts and coaches, energized by healthy food and drinks, inspired by workshops and talks and like-minded people, all this was this years climathon!


What were the challenges? Well, first challenge was all about food. Finding solutions on how Zurich residents can be motivated and empowered to contribute to an „edible city“ by cultivating and harvesting crops, fruits and flowers or using wild edible plants from urban areas.

Second challenge was energy based and how energy data can be used to motivate homeowners and renters to be aware of their energy consumption. How people can be motivated to save energy in their daily routines as well as how energy data can be included into these daily routines in a meaningful way?

Finding solutions on how residents can contribute to a climate friendly city planning reflecting the needs of the inhabitants was the third challenge. How are we able to maintain a high quality of life in the city of Zurich by holding urban spaces attractive for the local population.

And last but not least, how can we optimize and improve e-mobility infrastructure in Zurich? How to fit charging into users daily routines in a way that drivers do not see e-charging as a constraint anymore?

Carbon Delta combines these areas in their business hence they decided to use the climathon to pursue the calculation of Scope3 emissions in their model.

According to the Green House Gas Protocol, a huge majority of companies have, until now focused on measuring emissions from their own operations and electricity consumption. This approach neglected the emissions a company is responsible for outside of its own walls—from the goods it purchases to the disposal of the products it sells. They also suggest that the majority of total corporate emissions come from scope 3 sources, which means many companies have been missing out on significant opportunities for improvement. It under this background that Carbon Delta sought to expand in this realm during the 24 hour climathon in Zurich. The team sought to establish a methodology to calculate scope 3 emissions using category 11 as a basis. Category 11 is the area that focuses on the use of sold products.


The team came up with a new methodology by separating revenue by dividing the CO2 emissions of a company with the total revenue made from both financial services and car making itself. Through looking at the granular revenue areas, it is possible to calculate scope 3 data for more than 25 000 companies which was not possible before! Well done team!

The Carbon Delta team will be developing this idea further after the climathon but they are thankful to ImpactHub and to the sponsors for making it possible for them to get participate and brainstorm on this game changing methodology through the night. There were intense and exciting moments and it definitely paid off to join other innovators and entrepreneurs come up with solutions for tackling climate change.
