Challenge 1 "Sustainable accessible websites"

Make a real-life website more sustainable by applying the Web Sustainability Guidelines and the Web Content Accessibility Guidelines. How can you achieve the most impact in the given scenario? Get support from Łukasz Mastalerz of the Sustainable Web Design Community Group of the W3C.

Challenge 2 "IT Inventory"

Suggest strategies for a company to reduce the footprint of IT Hardware. Validate your suggestion running a simulation with real-life inventory data. Get support from the experts at Resilio.

Challenge 3 "Impact Framework"

Improve the impact framework of the Green Software Foundation by developing a new or extending an existing plugin. Get support from the inventors of the framework directly.

Challenge 4 "Sustainable Product Design"

Waste from Electrical and Electronic Equipment (WEEE) is a major problem in the industry. What if you could redesign everything? What would you do differently? Use principles of circular design (i.e. Ellen McArthur Circular Design Guide, Data-driven circular design) to address this problem with support from our team.


In general, challenges will be defined around the following areas:


We want businesses to prioritize climate issues and embed sustainability requirements into the day-to-day work of all employees.


Software engineers can make decisions which reduce the carbon pollution of their applications.


We can change the product design process to reduce upstream and downstream emissions.


While we transition to renewable energy, we can align compute load with low-carbon energy.
