Climate tracking apps measure your carbon footprint, helping you understand your personal climate impact.
The concept of a carbon footprint is simple: it includes anything that contributes to planet-warming emissions, such as gas consumed by your car or energy required to produce food.
Reducing your carbon footprint means contributing less of these gases to the atmosphere, but figuring out how to do so can be complicated.
Several mobile tracking apps can help people identify actions that create the most emissions and how to avoid them.

Apps provide a way to learn more about emissions and build better habits, which is why three popular ones were downloaded for review.
