Global carbon dioxide emissions hit a high of roughly 38 billion metric tons (GtCO₂) in 2023 (excluding carbonation), with coal use contributing 15.4 GtCO₂ to this total. Nevertheless, coal's share of total global CO₂ emissions fell from 96 percent in 1900 to 41 percent in 2023. In comparison, the share of CO₂ emissions from oil and gas during this period increased from less than five percent to 32 and 21 percent, respectively. Global CO₂ emissions from fossil fuels and industry have risen almost twentyfold since the turn of the 20th century.
