Unpacking the growth of global agricultural greenhouse gas emissions.

ABSTRACT: Agriculture, forestry, and other land use contribute about a fifth of total anthropogenic greenhouse gas (GHG) emissions. Mitigation efforts have emphasized "decoupling" that sustains production while lowering emissions per unit of output. However, the underlying decoupling mechanisms have not been fully characterized. We rely on a mathematical identity to decompose agricultural GHG emission growth ([Formula: see text]) into three parts: output ([Formula: see text]), emissions per unit of input ([Formula: see text]), and output per unit of input ([Formula: see text]) or total factor productivity (TFP). We then rely on official country-level data to quantify the historical contribution of these components. Over 1961 to 2021, we find that TFP growth-which captures the sector's ability to pro
