Fig. 3: Number of cattle ‘allowed’ for a given (maximum) soil carbon (C) sequestration in grasslands to offset the climate impact in a range of possible enteric CH4 emissions per cattle.
From: Risk to rely on soil carbon sequestration to offset global ruminant emissions
It is assumed that one tonne (t) of C would offset a continuous emission of 0.99 kg CH4 per year over 100 years, calculated based on a simple climate model27. The values for enteric CH4 emission represent a wide range of cattle types, including productivity, animal age, breed, size, diet, production systems and so on31. The red line (in both chart area and legend) indicates a cattle density of one head per hectare of grassland. Source data are provided as a Source Data file.
