The Asia-Pacific region produced 19 billion metric tons of carbon dioxide (GtCO₂) from energy use in 2024. China's CO₂ emissions are by far the highest in the Asia-Pacific region, at more than 10 GtCO₂ per year. The second most polluting region in 2024 was North America, where 5.6 GtCO₂ were generated, the majority of which came from the U.S.

Global COâ‚‚ emissions growth

Global COâ‚‚ emissions from energy consumption have more than doubled since 1970, reaching a record high of 35.5 GtCOâ‚‚ in 2024. The rise in emissions is mainly due to rapidly growing economies and increasing energy demand in developing regions. This is especially the case in the Asia-Pacific region, where emissions have almost tripled since the turn of the century. The Middle East has also seen a dramatic rise in emissions, going from producing the lowest COâ‚‚ emissions worldwide in 1965, to the fourth-highest as of 2024.

Atmospheric carbon dioxide concentrations

The increased burning of fossil fuels - as well as deforestation and other human activities - has seen atmospheric CO₂ concentrations surge in recent decades. In 2023, global atmospheric concentrations of CO₂ reached a record high of 424.61 parts per million, which is roughly 50 percent higher than before the industrial revolution.
