Fig. 2: Distributions of emissions intensity in key supplier sectors.
From: The importance of multiregional accounting for corporate carbon emissions
Across regions, there is wide variation in the average emissions intensity (emissions per dollar of products or services produced) of key supplier sectors (colored probability density plots in (a), such that the emissions intensity from a single-region (U.S.-based) model (black lines in (a) may substantially over- or underestimate the reality. Similarly large variation in the average emissions intensity of specific sectors within broader industry categories (gray density plots in (b), such that even multiregional models with fewer (more aggregate) industry sectors may also over- or underestimate the emission intensity of a specific sector (colored lines in b) by a similar margin.
