  "description": "The share of the world's consumption-based carbon dioxide emissions caused by the richest 10%, the richest 1% and the poorest 50% of people, ranked by income across the world, each year from 1990 to 2022. Consumption emissions count what a country's people buy, including imports, and exclude what it makes for export. The split between people depends on the Stockholm Environment Institute's assumptions about how emissions rise with income. These are shares of the world total, not tonnes per person. SEI also serves 2023, but builds it on territorial national emissions (where emissions happen) instead of consumption, so 2023 is not comparable and is not shown.",
