Despite everything, US emissions dipped in 2019

Just a week into the new year, and the first estimate of how much planet-cooking pollution the United States belched into the atmosphere last year is already in. It’s not the kind of report card you’d be proud to show your parents, but at least it won’t leave you in tears.

Perhaps surprisingly, total emissions fell 2 percent compared with the year before, according to the Rhodium Group, a research firm that frequently crunches climate numbers. The reason for that decline? The US is burning less coal. That’s been driving down emissions from electricity generation. But the way we get around, heat our homes, and manufacture our stuff, hasn’t had much of an effect.

“It’s a good-news bad-news story,” said Trevor Houser, a partner at Rhodium and author of the report. “In the electricity sector we had a banner year — we had the largest decline in coal generation in recorded history. But in the other 75 percent of the economy, emissions remain stubbornly flat.”

Coal has been in a slow-motion death spiral over the past ten years. The country now generates half as much coal-fired electricity as it did in 2009. And that trend continued through last year, as coal generation slid 18 percent.

Surging natural gas was the biggest reason for coal’s demise. Gas comes with its own problems for the climate– burning it releases carbon, and leaks release methane — but replacing coal with gas led to a decline in globe-warming gases, Houser said. Renewable energy from hydroelectricity, solar power, and wind turbines, increased 6 percent in 2019. So despite President Donald Trump’s vows to resurrect coal, it’s still sliding into history.

The same can’t be said of gas-powered cars and gas-fired furnaces — for the moment, those look locked in.

Cleaning up the electrical grid is a great first step to cleaning up other sectors. With enough low-carbon electricity, more people could drive electric cars and ride electric trains. Builders could start installing electric heat pumps rather than gas furnaces in houses. “But that’s not going to happen on its own,” Hauser said.

Nudging people toward clean electricity requires policy: Efficiency standards, building codes, incentives, and taxes. Some state and local governments are making these changes, but at the federal level, the Trump administration is doing its best to stop them. As a result, the country’s energy use seems to have its own laws of motion. It takes a lot of work to change direction, but it’s relatively easy to let things keep running as normal. You can see that in coal’s continued slide, as well as in the status quo in emissions from factories, cars, and buildings.

It was a bad year for carbon emissions, even in California

Carbon emissions are rising in the the United States, and it looks like the golden green state of California is part of the problem. Despite putting up acres of solar panels, California’s electric system produced more greenhouse gases in 2018 than in the previous year.

It’s part of a larger trend across the country. A preliminary estimate out this week says carbon dioxide emissions climbed 3.4 percent last year, the second largest increase in two decades, according to the research firm Rhodium Group.

What happened? An unusually cold spell last winter led people to turn up their furnaces. And after years of modest growth, the U.S. economy picked up in 2018. There were more planes in the air, more trucks delivering packages, more offices cranking air conditioners, and more factories burning fossil fuels.

In 2017, California had a relatively wet year, and was able to run water through hydropower turbines when the sun set over solar panels. There was less water to spare last year, so the state turned to gas plants in place of dams.

The rise in power-sector emissions is especially concerning in California because the state has made curbing pollution from power plants a priority, enacting legislation to promote renewable energy and cap fossil fuels. Yet California’s emissions have risen and fallen in line with the rest of the country.

In 2018, for instance, emissions from electricity generation rose 1.9 percent across the country, and 2 percent in California.

Trevor Houser, a climate and energy analyst at the Rhodium Group, said we shouldn’t make too much of California’s backsliding because the state had significant emissions reductions in the recent past. Last year’s 2 percent increase in electricity-sector emissions comes after a 9 percent decline in 2017 and a 13 percent decline in 2016. If you look at the three-year moving average, California is still making good progress when it comes to electricity.

Decarbonizing electricity is just the beginning of the challenge: “Far more important for California climate progress will be what happens in transportation, which is more than twice the emissions of the electric power in the state,” Houser said.

U.S. emissions peaked back in 2007, then quickly plunged with the Great Recession. A switch from coal power to natural gas and renewables also pushed down the country’s carbon pollution. All told, emissions fell 12 percent between 2007 and 2015. Since then, the country has continued to shift from super-polluting coal to less-polluting natural gas, but this report shows that we’ve been burning a lot more natural gas to make electricity.

Previously it had looked like the United States had a shot at meeting pledges made as part of the Paris climate talks, despite President Donald Trump’s rejection of that agreement. Now it’s painfully obvious. in Last year’s emissions have pushed the United States far off target.
