Weaning the world off of fossil fuels

The “yellow vests” in France are worrying greens around the world.

The worst riots in Paris in decades were sparked by higher fuel taxes, and French President Emmanuel Macron responded by scrapping them Wednesday. But taxes on fossil fuels are just what international climate negotiators, meeting in Poland this week, say are desperately needed to help wean the world off of fossil fuels and slow climate change.

“The events of the last few days in Paris have made me regard the challenges as even greater than I thought earlier,” said Stanford University environmental economist Lawrence Goulder, author of the book “Confronting the Climate Challenge.”

Economists, policymakers and politicians have long said the best way to fight climate change is to put a higher price on the fuels that are causing it — gasoline, diesel, coal and natural gas.

Taxing fuels and electricity could help pay for the damage they cause, encourage people to use less, and make it easier for cleaner alternatives and fuel-saving technologies to compete.

These so-called carbon taxes are expected to be a major part of pushing the world to reduce carbon dioxide emissions and try to prevent runaway climate change that economists say would be far more expensive over the long term than paying more for energy in the short term.

But it’s not so easy for people to think about long-term, global problems when they are struggling to get by.

Macron said the higher tax was his way of trying to prevent the end of the world. But the yellow vest protesters turned that around with the slogan: “it’s hard to talk about the end of the world while we are talking about the end of the month.”

The resistance to the fuel tax is a personal blow to Macron, who sees himself as the guarantor of the 2015 Paris climate accord, its strongest defender on the global stage. He has positioned himself as the antitrump when it comes to climate issues.
