Annual Global CO2 Emissions

Humanity releases about 37 billion tonnes of CO2 into the atmosphere each year/Collective & Conceptual

Global annual carbon dioxide emissions from fossil fuel combustion and industrial processes reached approximately 37.4 billion tonnes (37.4 Gt) in 2023. To visualize this, if you compressed all that CO2 into solid dry ice at -78.5 C, it would form a cube about 27 km on each side. China is the largest emitter (about 31%), followed by the United States (13%) and India (7%). Atmospheric CO2 concentration has risen from about 280 parts per million before the Industrial Revolution to over 420 ppm today. Each additional tonne of CO2 emitted contributes to warming of about 0.0000000000005 C. The cumulative emissions since 1751 total about 1.7 trillion tonnes.
