Opinion | To Fight Climate Change, We Need a Better Carbon Market
Gresham’s Law says that bad money drives out good. If you have two coins with a face value of $1, you will spend the bad one that contains 25 cents’ worth of metal and stash away the good one that contains $1 worth of metal.
Something like Gresham’s Law is at work in the carbon offset market, which was set up to fight climate change. Bad carbon credits are driving out good carbon credits.
