2024 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?

Focus Areas
The internet is the world’s largest machine. If we continue business-as-usual, the IT sector will be responsible for 14% of the world’s carbon emissions by 2040 [HBR, 2020]. From the Climate Action Tech community conversations, these 4 subjects have emerged as levers for changing our industry:
Business Culture &
Behavior Change
We want businesses to prioritize climate issues and embed sustainability requirements into the day-to-day work of all employees.
Green Software
Engineering
Software engineers can make decisions which reduce the carbon pollution of their applications.
Sustainable Product
Design
We can change the product design process to reduce upstream and downstream emissions.
Low-Carbon
Infrastructure
While we transition to renewable energy, we can align compute load with low-carbon energy.
