Over two fifths of people (44%) think that smog is a serious problem in the place where they live. This is the same as last year. One in three (34%) say it is not a great problem, whereas one in five (19%) do not see it as a problem at all. While fewer people than last year maintain that smog is not an issue in their area, there has been an increase in the number saying it exists but is not much of a problem.

The most common method of protection from smog is closing windows (32%) and not going outside (20%). A few people have houseplants with air cleansing properties (4%), use air purifiers (4%) or wear anti-smog masks when going out (2%). There is no change from last year in the frequency of the methods used.
