The impact of human and livestock respiration on CO₂ emissions from 14 global cities.

ABSTRACT:

Background

The CO₂ released by humans and livestock through digestion and decomposition is an important part of the urban carbon cycle, but is rarely considered in studies of city carbon budgets since its annual magnitude is usually much lower than that of fossil fuel emissions within the boundaries of cities. However, human and livestock respiration may be substantial compared to fossil fuel emissions in areas with high population density such as Manhattan or Beijing. High-resolution datasets of CO₂ released from respiration also have rarely been reported on a global scale or in cities globally. Here, we estimate the CO₂ released by human and livestock respiration at global and city scales and then compare it with the carbon emissions inventory fro
