Czechia Cumulative CO₂ Emissions (Global Carbon Budget)

## What this measures

The total carbon dioxide emitted from fossil fuels and industry within Czechia from 1860 (its first year in the data) through each year, in billion tonnes (gigatonnes) of CO₂. Each year adds that year's emissions to the running sum. Land-use change is not included. Annual; each value is dated December 31 of its year.

## Why it matters

Warming tracks the cumulative amount of CO₂ in the atmosphere, not any one year's emissions, so the running total is the measure behind "historical responsibility" and the remaining carbon budget. It shows who has emitted most over time, which can differ sharply from who emits most today.

## How to read it

It only rises; the slope is the year's emissions (climate.co2.emissions_mt.cze). Compare countries on the same year. The world total is climate.co2.cumulative_gt.world.

## What it does not say

It is territorial: emissions embodied in imported goods count where they were produced. International aviation and shipping count only in the world total. It covers fossil and industrial CO₂ only, not land-use change or other greenhouse gases, and early years are reconstructions. Borders are today's, so a country's history includes the years before it existed in its current form.
