Microsoft has committed to becoming carbon negative by 2030, and to supporting innovation with partners and society.

Since passenger cars are responsible for a significant part of global CO₂ emissions, one critical opportunity is to turn cars into a solution instead of a problem.

The challenge for teams is to design, and potentially develop, an inclusive system prototype (for example, but not limited to, hardware solutions, software solutions or conceptual procedures) that could be fitted into a passenger vehicle to track and virtually share CO₂ emissions from cars globally, while also providing suggestions on how to reduce emissions from driving.
