My own research (currently under review) using 2008 data shows wide variation in corporate carbon performance (Revenue / Emissions) within industry (denominator is Scope 1 + Scope 2). The following box plots illustrate the range of each distribution.
Note also that variation depends on the industry. For example, Consumer Staples and Industrials have lower ranges relative to other low emitting industries (note y-axis scale difference across the two panels). Bottom line? Whether from the perspective of IT sustainability or overall sustainability performance, data illustrate wide variation within industries. Why might this be the case? That’s the subject of a future post.
