Prompt
California (CA) is often cited as the leader in climate policy within the U.S. and in 2013
the state launched its cap and trade system (hereafter referred to as CTS) which regulates six different types of emissions for industrial and energy sectors within the state.
These two sectors account for an estimated 85% of all emission sources within the state.
The main appeal that market based policy instruments like a CTS (another example is a pigouvian tax) has is that it theoretically acheives an environmental goal at the
least cost to society. In other words, polluters that can reduce pollution the cheapest
will do so before those who can only do so at a high cost under a market based policy
instrument. For more background on what a general CTS is, click here. To learn more

Question : Proponents of CA’s CTS claim that the system is a success, reaching
CA’s annual emissions targets at least cost. What assumptions must hold for this claim
to be true?
