In the carbon-emission stabilization scenario proposed by Pacala and Socolow (2004) what does one wedge represent?

Question

Quizplus · Accepted Answer

Each wedge represents a strategy or approach that, over a period of 50 years, could potentially reduce carbon emissions by one gigaton per year, thus contributing to one-seventh of the stabilization effort needed according to their projections. Therefore, a wedge encompasses all these aspects: a specific amount of carbon emissions reduction, a fraction of the total reduction needed, and a distinct proposed solution or strategy.
