To greet the upcoming Shenyang World Horticulture Exposition, an environmental safety campaign was formally launched on April 2 in Shenyang. On the day, Shenyang Environmental Monitoring Station conducted several on-the-spot tests to the air quality inside 10 taxis, 3 public buses, and one hotel. Vehicles which meet air quality standards will be labeled as ecological or environmentally friendly.

"I gets more passengers with the mark of ecology attached on the back window of my taxi", said a driver whose taxi just was labeled with "green" mark.

With the improving environment of Shenyang, the indoor air quality has become a major concern for many people. Most people are aware that indoor air pollution can damage their health. Therefore, the city environmental protection bureau invited several municipal units including the traffic bureau and tourism bureau to jointly conduct the campaign which is expected to last until October.
