One possible version

Hello, everyone! It's nice to speak about Car Free Day, and I think it is a good idea．

First, many citizens will leave their cars at home to support Car Free Day．When we cut down the use of cars, air pollution will be reduced．

Meanwhile, encouraging citizens to use the green transportation means on Car Free Day will ease traffic jams．There are too many private cars now．Besides, green travel is the responsibility of both the public and the government．With more citizens turning to public transportation, the government will try to improve the public transport system so people will use private cars less．

Finally, it can enhance people's awareness of environment protection．The air pollution is becoming worse and worse now．If more people are aware of the danger of environment destroy, it achieves a lot．

In a word, everyone is a winner on Car Free Day if we can do a bit for our city．

Thank you for listening!
