About this data

Source: National Atmospheric Emissions Inventory (NAEI), Greenhouse gas inventories for England, Scotland, Wales and Northern Ireland: 1990–2024

• The nations' inventories are split out from the UK inventory, so they are consistent with each other and with the UK figures. About 10 million tonnes a year (mostly from offshore oil and gas) can't be allocated to a nation.
• Territorial emissions: greenhouse gases emitted within the UK, net of removals by forests and soils. Emissions from international aviation and shipping aren't included, as under international reporting rules.
• Gases are combined in carbon dioxide equivalents (CO2e), weighting each by how much it warms the climate over 100 years compared with CO2.
• The inventories cover 1990, 1995 and every year from 1998; the lines join these years. Per-person figures use ONS's mid-year population estimates.
