James Hiatt lives in an area along the Mississippi River in Louisiana that has been dubbed “Cancer Alley.” Teeming with chemical plants and oil and gas refineries, the air the residents of this area breathe contains more carcinogens than anywhere else in the country.

One of those oil and gas facilities is the Calcasieu Pass liquified natural gas (LNG) terminal, which has further devastated public health, local livelihoods, and marine wildlife. Last week the Biden-Harris administration’s Department of Energy (DOE) paused the permitting of new LNG projects. The decision stops the gas industry’s plans for the even larger CP2 LNG terminal right next door.

This move was perhaps the boldest rebuke ever from a U.S. president against the oil and gas industry. President Biden, Vice President Harris, and Secretary of Energy Granholm — whose support for the move was especially crucial — did the right thing.

Millions of us are celebrating along with James Hiatt, who says, “I’m thankful for this pause in granting gas export licenses; the DOE has finally heard the wake-up call. The gas industry was planning to inundate my hometown with LNG terminals.”

American families’ pocket- books will be thankful as well.

Any word you hear from the fossil fuel industry or the politicians in their pockets about how this decision harms American consumers or the economy is a lie.

As Mr. Hiatt points out, “exporting LNG drives up domestic energy costs, affecting everything from home heating to food prices.”

Pausing the LNG boom will keep global energy markets more stable. It will help move economies and electric grids toward using less expensive and more resilient renewable energy sources. It will keep 681 coal plants worth — or 548 million gasoline-powered cars worth — of planet-warming greenhouse gasses out of our atmosphere each year.

All of this is critically important. But so is Mr. Hiatt’s point about the “finally heard wake-up call.”

For years, activists, along with scientists and others, have been sounding the alarm to get those in power to wake up. Some of the most powerful voices have been those of young people. And we should all appreciate what it has taken for those young people to maintain their determination.

The American Psychological Association defines “eco-anxiety” as “a chronic fear of environmental doom.” In 2021, Lancet Planetary Health surveyed more than 10,000 young people, ages 16 to 25, in 10 countries. Anxiety about climate change impacted the ability of more than 45% of these young people to function in their daily lives; 75% were “frightened” of the future. And it exposed a key feature of eco-anxiety: hopelessness.

Half the young people in the study described feeling helpless and powerless. Now, we know that despite the fear, young activists have been among our fiercest leaders in the fight against the climate crisis. They have not given in to the lingering despair.

But, as a piece on eco-anxiety in the Harvard Political Review pointed out, young people have felt like they are alone in the fight. And, “if no one is listening and no change is happening, then pushing forward can feel hopeless.”

That is why, aside from the emissions numbers … aside from the economic and energy security benefits … the Biden-Harris administration’s LNG decision is a win for hope. And hope is a powerful thing.

In his statement about the decision, President Biden said, “We will heed the calls of young people and front line communities who are using their voices to demand action from those with the power to act.”

This victory for climate-concerned people the world over — and the planet itself — is proof that organizing works. Grabbing the bullhorn and telling your story — even if the crowds don’t listen right at first — matters.

This LNG decision is a momentum builder. And a clarion call for even more organized action on the climate crisis – especially from young people.
