The Human Impacts Database

A collection of useful numbers for quantifying the impacts of the human presence on Earth.

This quantity comes from a time series measurement and the most recent value (2018) is reported.


Value:		(4.22 ± 0.33) × 10¹³ kg CO₂ / yr see this value in other units This is equivalent to... (1.15 ± 0.09) × 10¹³ kg C / yr 42.2 ± 3.3 Pg CO₂ / yr 11.5 ± 0.9 Pg C / yr
HuID:		60670
Relevant Year(s):		2018
Summary:		Mass of carbon dioxide (CO₂) annual emissions from all human activities, which are categorized as either fossil CO₂ emissions or land use change emissions. The value reported is for 2018, and can be found in Table 6 of Friedlingstein et al (2019).
Method:		The uncertainty value represents one standard deviation. It is obtained from the uncertainty of fossil fuel emissions and land use change emissions, assuming uncorrelated errors following the original publication. Fossil CO₂ emissions are based on energy statistics and cement production data, while emissions from land use change, mainly deforestation, are based on land use and land use change data and bookkeeping models.
