How much Carbon Dioxide is emitted by an idling gas vehicle?

An idling gas vehicle emits approximately 0.4 to 0.5 grams of carbon dioxide (CO2) per minute. Over the course of an hour, this can amount to roughly 24 to 30 grams of CO2. While this may seem relatively small, it accumulates significantly when considering the vast number of vehicles idling frequently, contributing to air pollution and greenhouse gas emissions. Minimizing idling time can help reduce overall emissions.
