The International Monetary Fund chief has hailed the landmark agreement reached in Paris "a critical step forward" for addressing global climate change in the 21st century and said her key message is to "price carbon right."
Governments must now put words into actions, in particular by implementing policies that make effective progress on the mitigation pledges they have made.
Charging for the emissions of fossil fuels puts in place the needed incentives for low-carbon investments; it also provides revenues to safeguard the poor, reduce debt, and lower the burden of other taxes on households and businesses.

Labour's shadow energy and climate change secretary has welcomed the Paris climate deal, calling it an "historic moment to be celebrated".
Lisa Nandy said there was still "a huge amount of work" to ensure it is delivered upon.
For the first time ever the nations of the world have come together to agree that every single one of them will act to cut carbon pollution.
In the coming months and years we have a huge amount of work to do to deliver on the promises made in Paris, but this deal will take us much, much closer to climate safety. We now have a common goal of limiting temperature rises to 1.5 degrees and an international plan of action.
That matters, and it makes this a historic moment to be celebrated.
Campaigners at Greenpeace have welcomed a new UN deal on climate change, saying it was a good first step.
Charity chiefs also urged Prime Minister David Cameron to ensure action is taken to help meet the terms of the deal - and turn his back on the fossil fuel industry.
The glass is half full not half empty, but who is paying for the next round is the key question.
Will it be the fossil fuel industry that now has to be phased out or people across the globe who will ultimately pick up the tab if there is lack of action following the successful climate talks?
The recent floods in Cumbria have shown the answer has consequences for Britain. Now it's David Cameron's turn to decide whose side is he on - the old polluters who caused the problem or the new renewable technologies that have just been given a shot in the arm.
