Briefings

A University of Bath-led study estimates human CO2 production rose 74% from 1985 to 2015, reaching 2.05 billion metric tons annually. This finding helps scientists track carbon sources and human impact on the climate system.

Key points

• Human CO2 production increased by 74% between 1985 and 2015.
• Total annual output reached 2.05 billion metric tons.

Context

This study provides updated estimates of anthropogenic carbon emissions, offering insights into how human activity contributes to the global carbon cycle over the past three decades.

Limitations

Data covers only 1985-2015; future projections remain uncertain. No specific city, region, or country is identified in the source.
