Canadian Air Pollutant Emissions Inventory Since 1990

Canada's Air Pollutant Emission Inventory (APEI) provides annual emissions data for criteria air contaminants, heavy metals, and persistent organic pollutants across all known sources. The dataset tracks historical trends from 1990 onward, compiled by Environment and Climate Change Canada to support air quality management and reporting.

Use Cases

• Analyze historical trends for specific pollutants like PM2.5, NOx, and VOCs across Canada to evaluate policy effectiveness.
• Model emission correlations between criteria air contaminants (e.g., SOx) and heavy metals (e.g., Mercury) from different source sectors.
• Forecast future emissions of persistent organic pollutants, including Dioxins and furans and polycyclic aromatic hydrocarbons, using time-series data since 1990.

Strengths

• Covers emissions data from 1990 onward, providing over 30 years of temporal coverage.
• Includes a detailed list of pollutants across three major categories: criteria air contaminants, heavy metals, and persistent organic pollutants.
• Compiled from facility-reported data and science-based estimation tools for a national overview.

Limitations

• Specific row count, column structure, and granular sample data are unavailable from the input.
• Data is presented in HTML format, which may require significant extraction and parsing for analytical use.
