It has been anticipated that climate change impacts ambient air pollution and thereby affects indoor air quality through ventilation. Yet, it is not clear how a changing climate, along with new developed interior building materials, products, and air cleaners, affects indoor air quality, and how to minimize negative effects. In this paper, ozone, as one of the greenhouse gases, has been selected to examine the photochemical mechanism for the explanation of ground level changes in the outdoors. The effects of temperature and precursors on ground level ozone formation have been discussed. Ozone concentration changes for different regions within Canada in recent 20 years are examples to demonstrate the trend of ozone levels in the future. In addition, the indoor sources contributing to the ozone levels are characterized. Moreover, this paper explores the feasibility of photocatalytic oxidation (PCO) technology based air cleaners for indoor ozone removal with the objectives of providing reliable technology and updating the literature.
