The aim of this study was to determine the elementary teachers' knowledge about air pollution. Ozone depletion, global warming, acid rain, and renewable energy were also addressed in this study to get holistic picture about air pollution. A total of 183 teachers from the 91 schools in Ankara participated to the study. The data obtained were analyzed by means of both quantitative statistical and document analyses techniques. Results revealed that majority of the teachers have an idea about the basic air pollutants and the air pollution problem it causes, like CO2, CH4, SO2 and NOX, they do not seem as having an in depth knowledge about the air pollutants and corresponding air pollution problems. Teachers' knowledge about renewable energy was quite satisfactory. It was argued that geographical nature of Turkey (having sunny seasons, being a peninsula, and having spring waters) improved teachers' knowledge about renewable energy sources.
