A “Wedge” Is…

A strategy to reduce carbon emissions that:

  • Grows in 50 years from zero to 1.0 GtC/year

  • Has already been commercialized at scale somewhere

Cumulatively, a wedge redirects the flow of 25 GtC in its first 50 years. This is 2.5 trillion dollars at $100/tC.

A “solution” to the CO2 problem should provide at least one wedge.
