Methods by country

Draft

Planned for 2026: a filterable table with a clickable map, and per-country details on trade reconciliation, accounting basis, currency and price index, and benchmarked sectors.

Each country’s tier sets which kind of IO table and emissions data it starts from. See IO sources by country tier for the IO tables and GHG data by country tier for the emissions data.

The data sources and years used can differ between the dollar years that factors are published for, so the table is given for each set of dollar years that share the same data.

Tier 3 countries share one IO proxy table, a blend of Malaysia (30%) and Tunisia (40%) from the ICIO for 2020 and Mexico (30%) from FIGARO for 2023; the table gives 2020, the year of most of the blend. They also share one set of GHG proxy emissions, scaled to each country’s fossil CO₂ total from EDGAR (see Tier 3: Proxy emissions).

The rest-of-world region is not in the table. Its input recipe and emission intensities are pooled from Colombia, Mexico, Türkiye, and Chile.

2024, 2025, and 2026 emission factors

The release candidate’s 2024, 2025, and 2026 factors are all built from the same data, below. Each is expressed in its own year’s dollars; see User guidance.
