One model, fixed for the quarter: U.S. EPA USEEIO v2.0.1 at 411-commodity detail (USEEIOv2.0.1-411). Every copied result names it.
What is in it
- Economy. The 2012 U.S. benchmark input-output accounts (Bureau of Economic Analysis), producer prices, 411 commodities.
- Resource use and emissions. U.S. satellite tables of about the same period: greenhouse gases, criteria air pollutants, water, land, minerals, energy, waste, pesticides and toxic releases, plus jobs and value added.
- Indicators. 23, characterized with TRACI 2.1; the list with units is in Documentation.
- Price adjusters. Purchaser-to-producer and price-year factors for 2002–2018, which the Explorer applies to your input.
Where it comes from
EPA builds and publishes the model (public domain). The files served here are EPA's build as packaged by the ModelEarth project, checked against EPA's published workbook (largest relative deviation 5 × 10⁻¹⁶); they are listed in Documentation. The same model also runs on eiolca.net, which carries the older U.S. and international models as well.
Against the 2002 model the course used before
- 2012 economy, 411 commodities; before: 2002, 428 sectors.
- Indicator names and groups follow EPA and TRACI 2.1. No indicator equals the old "Energy"; see Documentation.
- Criteria pollutants are individual flows (SO₂, NO₂, CO, lead, two particulate sizes), not a category.
- Inventories are a decade newer, so most air-pollutant results are lower for the same sector: partly real change, partly definition.
Look inside
- Impact profile: one or more sectors across the indicators.
- Sector heatmap: all 411 sectors against all indicators.
- IO tables: what a sector buys and who buys from it, first tier only (the A matrix, not the Leontief inverse).
