## Abstract
Abstract Car Free Day is a movement to reduce the level of air pollution in big cities around the world caused by the emission load of vehicles. The event gives motorists and commuters an idea of their locality with fewer cars. Vehicles produce CO emissions from the fuel combustion process. This research was conducted on alternative roads in 3 Car Free Day locations in Makassar City, which are 1) Boulevard with an alternative road Ance Daeng Ngoyo, 2) Sudirman with an alternative road Karunrung and 3) Losari Beach with an alternative road Hj. Saleh Daeng Tompo. Analysis of measurement data using the method of the number of vehicles and Indonesia’s emission factors and Indian emission factors. The results of the study show that the CO emission load on Jl. Ance Daeng Ngoyo and Jl. Karunrung, when Car Free Day (Sunday) is smaller than Non Car Free Day (Monday) while on Jl. Hj Saleh Daeng Tompo when Car Free Day (Sunday) is greater than Non Car Free Day (Monday). The results of statistical tests also showed that there were no significant differences when Car Free Day (Sunday) and Non Car Free Day (Monday).
