The Air Pollution Emission Account (APEA) is a framework used to quantify and analyze air pollutant emissions from various sources within a specific region or sector. It provides comprehensive data on emissions of pollutants such as sulfur dioxide, nitrogen oxides, particulate matter, and volatile organic compounds. APEA helps policymakers and researchers assess the impact of air pollution on public health and the environment, track changes over time, and develop strategies for emission reduction. The account integrates economic and environmental data, facilitating informed decision-making for sustainable air quality management.
