Keep a check on your vehicle’s CO2 emissions with the “Puff.” Designed by design studio Amateur Human, this cartoon cloud-shape car accessory visualizes the amount of pollution your car produces in real time. It is attached to the exhaust pipe of a car and glows in different colors, representing the exhaust levels being emitted by the car.


If the device illuminates in bright green color, your car emits the lowest rate of pollution, but in case it is red, you are contributing in ruining Mother Nature. As far as the driver of the car is concerned, he or she can view the number of pounds of CO2 emitted per minute, the total pounds emitted during the current trip along with emission data over time through an iPhone app.
