Here is how you can simulate the EICDA in En-ROADS: 

Under the Carbon Price slider, adjust the advanced settings:

Carbon Price


“Years to achieve initial carbon price”

1 year

“Final carbon price”

$815/ton CO2

“Year to start achieving final carbon price”


Years to achieve final carbon price”

80 years

See this scenario in En-ROADS

Note: En-ROADS is a global model, and the EICDA is a proposal for a U.S. carbon price. This method simulates a carbon price similar to the EICDA plan, if it were implemented globally rather than solely in the U.S.
