Reaching worldwide consensus to make substantial, immediate changes has been elusive. Understandably, nations that are developing (even big ones like China) do not want restraints imposed and resent developed nations calling for restraints.
The parallel commentary by Irwin Rubenstein is right on point for a way to get the ball rolling. A revenue-neutral carbon fee and dividend to all households does not amount to a tax and sends a clear signal to innovators, entrepreneurs and markets to charge ahead with clean energy. The border tariff will motivate other nations to follow in stride.
I am hopeful such a plan could quickly lead to breakthroughs that lower the cost of clean energy so that the world eagerly jumps on board to clean up its act.
