Cutting CO2 emissions – who leads the world!

The U.S. leads the world in cutting CO2 emissions — so why aren’t we talking about it?

On the 31st July, I republished a TomGram from William deBuys that showed some pretty frightening aspects of climate change in the South-West USA.  Then there was the video on the 10th August, last Friday, that spelt out in very clear ways how the world is in a new, unfamiliar place.  It would be so easy to think it’s all going to hell in a handbasket.  So a change of tone.

There was an article on Grist by David Roberts about the US leading the world in cutting CO2 emissions.  David kindly gave me permission to republish it on Learning from Dogs.

U.S. leads the world in cutting CO2 emissions — so why aren’t we talking about it?

By David Roberts
Contrary to popular belief, the U.S. is making progress on climate change.We have cut our carbon emissions more than any other country in the world in recent years — 7.7 percent since 2006. U.S. emissions fell 1.9 percent last year and are projected to fall 1.9 percent again this year, which will put us back at 1996 levels. It will not be easy to achieve the reductions Obama promised in Copenhagen — 17 percent (from 2005 levels) by 2020 — but that goal no longer looks out of reach, even in the absence of comprehensive legislation.

Why isn’t this extraordinary story a bigger deal in U.S. politics? You’d think Obama would be boasting about it! Turns out, though, it’s a little awkward for him, since several of the drivers responsible are things for which he can’t (or might not want to) take credit.

Awkward: that whole recession thing

First off there’s the Great Recession, which flattened electricity demand in 2008. It has never recovered — in fact, in part due to 2011′s mild winter, it has even declined slightly:

For obvious reasons, boasting about the environmental benefits of the recession is not something Obama’s eager to do.

Awkward: frack-o-mania

The second big driver is the glut of cheap natural gas, which is currently trading at the 10-year low of about $3 per million British thermal units. This is absolutely crushing coal, the biggest source of CO2 in the electric sector:

The share of U.S. electricity that comes from coal is forecast to fall below 40% for the year, its lowest level since World War II. Four years ago, it was 50%. By the end of this decade, it is likely to be near 30%.

Here’s U.S. electricity generation from 2000-2012. Look how dramatic coal’s recent plunge is:

In April, coal and natural gas both contributed 32 percent to the U.S. electricity mix — equal for the first time since EIA started collecting data in the ’70s. This is, as Alexis Madrigal emphasizes, an extraordinary shift, unprecedented in the history of the U.S. electrical system.

It’s helpful to Obama to be able to point to cheap natural gas when people accuse his EPA of killing coal. And it’s helpful in his effort to claim “all of the above.” But fracking’s potential environmental and health impacts has quickly made it a flash point with his environmental base (and his Hollywood base), so it’s at the very least a fraught subject.

Awkward: Kenyan socialist EPA sharia tyranny

A less significant driver of the switch from coal to natural gas is the EPA’s long overdue rollout of new or tightened clean-air rules on mercurySO2 and NOx, and CO2. Those rules may do more work later on down the line when/if natural gas prices rise again, but for now the best analysis [PDF] shows that natural gas is doing most of the work killing coal. Nonetheless, EPA regs have proven a source of potent right-wing attacks on Obama and he’s probably not eager to call undue attention to them.

Thus: silence in the political world

So: given the fact that the decline in emissions is driven, at least in the conventional narrative, by an explosion in fossil fuel production, a recession, and a series of EPA regulations, it’s not hard to see why Obama isn’t eager to put it front and center. It’s got a little something for everyone to hate.

And of course the right isn’t eager to talk about it either, since conservative dogma tells us that there’s no way to grow the economy and shrink CO2 emissions at the same time … and yet, uh, that’s what’s happening. At the end of 2012, our economy will be much larger than it was in 1996, yet its carbon emissions will be the same. If conservatives acknowledge that it’s possible to loosen the link between climate pollution and economic growth, they’ll have to explain why we shouldn’t do a whole lot more of it.

Still, while the story has remained largely sub rosa in political media, there are several overlooked details that paint a happier picture than the conventional one above. There’s more to this story than natural gas and recession.

Happy: Coal’s getting its ass kicked by activists

First, it isn’t just natural gas and EPA taking coal out — it’s the kick-ass anti-coal movement! Fighting tooth-and-nail, plant-by-plant, it has blocked new construction and shut down over 100 existing plants.

Beyond Coal: 112 down

The campaign has been so disciplined and successful that it’s drawn the support of NYC Mayor Michael Bloomberg, who does not typically invest his own money in feel-good symbolism. He expects accountability and he’s getting it. Like the man said, “Ending coal power production is the right thing to do.”

Happy: Clean energy is happening

Renewable energy still represents a small portion of U.S. electricity generation, but that fact obscures its outsized impact. The U.S. doesn’t need to add a ton of renewables for things to start shaking loose.

Here’s growth over the last decade:

One thing that jumps out is that renewables are growing much faster in some places than others. South Dakota now gets 22 percent of its electricity from wind, Iowa 19 percent. The top two states in total installed wind are Kansas and Texas. The top two for wind jobs are Iowa and Texas. That’s three red states and a deeply purple one — a wedge separating clean energy from the climate culture wars. That portends accelerating changes in the political economy.

Also driving changes in political economy: 29 states and D.C. now have mandatory renewable energy standards.

Installed wind and solar have doubled in the U.S. since Obama took office. Costs for solar are plunging like crazy and onshore wind power may be competitive with fossil fuels without subsidies by 2016. The National Renewable Energy Laboratory says the U.S. could get 80 percent of its power from renewables by 205o. Given that “official” projections of renewable energy growth have been consistently beneath the mark, it’s not unreasonable to think we may be underestimating future growth.

And renewables don’t have to get that big to start making waves. The sun shines most when the most electricity is being used — “peak demand” — so it serves to sharply reduce peak prices. Turns out that’s where utilities make a lot of their money. U.S. utilities are being forced to crank off coal plants when peak prices drop and then crank them back on afterwards.

It is no fun to turn coal plants on and off — it’s slow, laborious, and kills their economics. More and more, utility managers are turning toward upgraded, smarter grids and more flexible, responsive “mid-load” plants (i.e. natural gas). By hacking off peak prices, renewables will make the dynamics even worse for coal, well before they reach a large proportion of total electricity.

So renewables are a bigger part of this story than they appear, and getting bigger.

Happy: Demand is leveling off long-term

It’s not just the recession that’s bringing down U.S. energy demand — the leveling off of demand is a long-term trend. The U.S. Energy Information Administration (EIA) projects energy use will grow quite slowly through 2035:

And this is almost certainly conservative: EIA doesn’t model policy changes, underestimates the role of technology, ignores rising fossil fuel prices, and is incapable of predicting cultural shifts.

For instance, few projections anticipated the sharp decline in driving in the U.S., which has been driven (ahem) as much by cultural and demographic factors as by economics.

Or consider the dramatic progress in energy use in buildings, which was also not anticipated by EIA. From Architecture 2030 comes this graph, which compares the EIA Annual Energy Outlook (AEO) projections on U.S. building stock from 2005 with the ones from 2012:

The growth in U.S. building stock is slowing (in part — but only in part! — due to the recession), but growth in building energy consumption is dramatically slowing, thanks to advances in energy efficiency technology. EIA now expects CO2 emissions from the building sector to decline by 2035. That’s a pretty big change from going up by over 50 percent!

And that’s just with straight-line projections. If “best available demand technologies” are deployed, it looks like this:

Click to embiggen.

It’s within our reach to reduce the CO2 emissions of the building sector almost 22 percent! Given that building standards are one of the few areas of bipartisan agreement on energy these days, it’s not crazy to think that we’ll get closer to the latter projections than the former.

And the EIA projections for building energy consumption, Architecture 2030 notes, do not incorporate “sustainable planning applications or passive heating and cooling, natural ventilation, daylighting, or spatial configuration and site design strategies,” all of which are gaining in popularity and sophistication.

In short, there’s reason to think the demand-side story is similar to the supply-side story: official projections are dramatically underestimating potential.

Worry, but be happy

To sum up: yes, the explosive growth of natural gas and the Great Recession played a big part in U.S. climate emissions declining in recent years. And either of them could reverse in years to come. But they are not the whole story. There are real transitions underway — seedlings that can be watered and fertilized.

As Brad Plumer notes, America’s modest progress to date still leaves the world on a pathway to climate catastrophe. But it also shows that projections are not destiny. Things can change, and quickly.

Let me just pick out two sentences from near the end, “But they are not the whole story. There are real transitions underway — seedlings that can be watered and fertilized.”

It serves as a very good reminder that many people are voting with their feet, so to speak, and making a difference.

  1. Very thorough – and amusing – summary. It’s great to hear that coal is currently getting its ass kicked but, the biggest problem remains the intention of the fossil fuel industry to burn them all simply because we can… It is cumulative emissions that matter and we are currently planning to emit too much.

    Climate Denial Crock of the Week recently re-published a couple of videos explaining what a sustainable/renewable energy future might look like:


    1. Just out of interest what was it about David’s article that you found amusing? Genuine question, by the way.

      There was a piece in a recent issue of The Economist, that I can’t now put my hands on, that pointed out that the weaker economy of the country had to be taken into account as a factor in this reduction of CO2 output.

      Nevertheless, this is good news. As the Transition US website points out on their home page, of the 443 official initiatives worldwide, 123 are official US initiatives, some 28% of the total. That has to be applauded.


      1. What’s amusing is obvious: USA USA USA! Let’s all chant together! Louder! One has to put things in perspective:in 2008 USA CO2 emmissions peaked at nearly 1,600 million metric tons. Now they are somewhat below 1,400 million metric tons (first quarter 2012). So, right, we are down to first quarter of 1992.

        That’s still more than 5 billlion tons of CO2 to be added generously to the atmosphere in 2012, courtesy of the grand old USA.

        Let see the long faces when the Greenland icecap comes unhinged next year (my half prediction). Washington rats will have to struggle for the high ground…

        For another easy read, just out:


      2. I can’t argue with the thrust of your position, not at all. However, my naive, quaintly hopeful, dream is that of all the countries in the world that a) could set the lead and b) make the biggest and quickest difference it is the United States of America. Maybe the plutocrats will sleep in one morning! 😉


      3. H’mm, Mr Ayme puts his finger on the kernel once again! Christine of blogsite, 350 or bust, has a recent post that referred to an article from Bill McKibben published in Rolling Stone politics. Here’s a taste:

        There’s no place on Earth that’s changing faster – and no place where that change matters more – than Greenland. Late last month, NASA reported that ice all across the vast glacial interior of the world’s largest island was melting – a “freak event” that hadn’t occurred for at least 150 years. The alarming discovery briefly focused the media’s attention on a place that rarely makes headlines. RAPID ICE MELT BAFFLES SCIENTISTS, The Wall Street Journal declared.

        In fact, scientists weren’t baffled at all – a paper published just weeks before had predicted that an abrupt, islandwide melt was imminent. The rapid loss of ice is only the latest in a chain of events that have upended conventional understanding of how the Earth’s “cryosphere” – its frozen places – behave. Taken together, the events offer new insight into how fast the world’s seas are likely to rise as a result of global warming – and hence, the fate of major cities like New York and Miami and Mumbai.

        Brace yourself and read it!


  2. The water flowing on top of the icecap makes lakes, and flows down “moulins” (yes, French word). A lake can drain in minutes (so, please, no ice cap swimming!)

    The moulin can be 15 meters across, 3,000 meters deep. The water ends up on the bottom (remember the Earth is a giant nuclear fission reactor, so it is warm…). There it acts a lubricant… So the glacier slips, and can do so suddenly, in one big chunk. 6 Richter quake have been registered…

    Funs and games all. It will be funny to see the plutocrats’ long faces, when a command economy of dikes will be Washington’s number one pre-occupation…

    As far as the USA is concerned, the CO2 pollution is at 17 tons per capita per year. Not as bad as inexcusable Australia and Canada, but far removed from the European Union with its 7.5 tons…
