For the second time Greenpeace UK commissioned DensityDesign an infographic, this time for a report on McKinsey’s Marginal Abatement Cost Curve (MAC).
The MAC curve is a bar chart which describes a set of different options available to reduce carbon emissions. MAC curves are a succession of different steps, each one being a different potential measure, with its height representing its cost and its width representing the amount of carbon abatement it could deliver.

There are, though, some issues with McKinsey’s curve.
First of all, McKinsey has never been transparent about the data and assumptions used for the curve calculation. That is, there has never been any scientific peer review of any of the calculations made to draw the MAC curve.
Secondly there are issues about the underestimating or overestimating of certain measures represented in the curve.
The MAC curve suffers of oversimplification of the representation of an economy, as it doesn’t take in account many of the interactions and evolvements of an economic environment.
For a deeper analysis of these and other issues Greenpeace has made available the full report about the MAC curve and its impact on REDD policies.
