ESSD - Global CO2 emissions from cement production,

CDIAC's method for estimating process emissions from cement production by country is taken from a report by Griffin (1987) and requires that cement production data in tonnes are multiplied by a fixed factor 0.136 to obtain tonnes of carbon emitted as CO 2, i.e. 1 t of cement produced results in 0.136 × 3.667 = 0.50 t CO 2 (Boden et al., 1995).
