Air Pollutant Emissions Data Inventory

Estimated air pollutant emissions based on a 1 km × 1 km grid. The base year for the estimation is 2023 (ROC Year 112). The grid covers the main island of Taiwan. Coordinates are based on the TWD97-TM2 coordinate system with the 121° central meridian, representing the lower-left corner of each grid cell. The total estimated emissions are aggregated from point sources, line sources, area sources, and biogenic sources. The air pollutants covered include TSP, PM10, PM2.5, SOx, NOx, and NMHC.
