Abstract : It explores the influence of environmental tax and technology on reducing air pollution emissions in OECD countries. Panel data between 2000 and 2021, covering 21 years, is uses. Key variables are: annual gross domestic product, environmental tax, patents on pollution technology, air pollution abatement technology, population, and three air pollutants. The analysis technique is ARDL. The study finds a significant impact of environmental tax and technology on Nitric Oxide. The long-term relationship between Nitric Oxide and the independent variables was inconclusive. The analysis finds both short-term and long-term effects of technology and tax policy on Carbon Dioxide. For Particulate matter short term effect exists with no long term influence. Although it establishes that a country's population and its economic prosperity (measures by GDP) are significant mediators in the effect of technology and tax policy on air pollution, at least in the short term. The environmental tax has not been failed in reducing Carbon Dioxide pollutants and has been effective with Particulate Matter (PM2.5). Technology has significantly reduced pollutants. GDP and the population of the OECD countries were significant mediators in the relationship between environmental tax, technology, and pollution. The environmental tax's impact on lowering pollutant emissions was obvious in short- term. Whereas, in whole the study variables, the long-term significance of the emissions reduction remains small, suggesting that the current environmental taxes do not have an adequate long-term effect. Air pollution is one of the realest existential threats today, and the needs to understand and come up with technologies and mechanisms of curbing air pollution has never been more important. As a whole governments and relevant scientific bodies should understand that long-term sustainability factors such as sufficient funding, ongoing sensitization, and more explicit long-term targets are necessary to effectively implement environmental laws and policies in OECD countries.
