Energy-related carbon dioxide emissions decreased in nearly every state from 2005 to 2013
November 23, 2015, Principal contributor: Perry Lindstrom
The United States has a diverse energy landscape that is reflected in differences in state-level emissions profiles. Since 2005, energy-related carbon dioxide (CO2) emissions fell in 48 states (including the District of Columbia) and rose in 3 states. EIA’s latest analysis of state-level energy-related CO2 emissions includes data in both absolute and per capita terms, including details by fuel and by sector.
This analysis measures emissions released at the location where fossil fuels are consumed. Therefore, to the extent that fuels are used in one state to generate electricity that is consumed in another state, emissions are attributed to the former rather than the latter. An analysis attributing emissions to the consumption of electricity, rather than to the production of electricity, would yield different results.
The 10 states with the highest levels of energy-related CO2 emissions in 2013 accounted for half of the U.S. total. These 10 states also have large populations and account for slightly more than half (53%) of the nation’s total population. California was the second-highest emitter in absolute terms (353 million metric tons of carbon dioxide, or MMmt CO2), behind only Texas (641 MMmt CO2). But California was also the fourth-lowest emitter on a per capita basis, behind the District of Columbia, New York, and Vermont. Relatively small states such as Wyoming and North Dakota had much higher levels of per capita emissions in 2013, nearly seven times and five times the national average, respectively.
Energy-related CO2 emissions come from coal, petroleum, and natural gas consumed within a state to produce electricity (38% of U.S. total), to transport goods or people (33%), to operate industrial processes (18%), or to directly fuel equipment in residential and commercial buildings (10%). The consumption levels by fuel and by sector vary considerably by state. For example, coal consumption accounted for 78% of energy-related CO2 emissions in West Virginia in 2013, while coal only accounted for 1% of emissions in California.
Consumption of petroleum accounted for more than 90% of energy-related CO2 emissions in two states, Hawaii and Vermont, but for different reasons. In both states, emissions from the transportation sector accounted for more than 50% of energy-related emissions. In Vermont, the nonelectric (or direct) residential share of total emissions was 23%, mostly from petroleum-based fuels such as heating oil used to fuel furnaces and water heaters. Vermont’s electric power sector share of emissions from petroleum was only 0.2%, as very little of the state’s electricity in 2013 was generated from petroleum or any other fossil fuels. Hawaii, on the other hand, has very little direct use of petroleum for residential heating but much higher use of petroleum for power generation.
U.S. Energy-Related Carbon Dioxide Emissions, 2014
Release Date: November 23, 2015 | Next Release Date: October 2016 | full report
U.S. Energy-related carbon dioxide emissions increased 0.9% in 2014
Energy-related carbon dioxide (CO2) emissions increased by 50 million metric tons (MMmt), from 5,355 MMmt in 2013 to 5,406 MMmt in 2014.
The increase in 2014 was influenced by the following factors:
Real gross domestic product (GDP) grew by 2.4%;
The carbon intensity of the energy supply (CO2/Btu) declined by 0.3%; and
Energy intensity (British thermal units[Btu]/GDP) declined by 1.2%.
Therefore, with GDP growth of 2.4% and the overall carbon intensity of the economy (CO2/GDP) declining by about 1.5%, energy-related CO2 grew 0.9%.

US carbon pollution from power plants hits 27-year low
By Seth Borenstein, Aug. 5, 2015 5:00 PM EDT
WASHINGTON (AP) — Heat-trapping pollution from U.S. power plants hit a 27-year low in April, the Department of Energy announced Wednesday.
A big factor was the long-term shift from coal to cleaner and cheaper natural gas, said Energy Department economist Allen McFarland. Outside experts also credit more renewable fuel use and energy efficiency.
Carbon dioxide — from the burning of coal, oil and gas — is the chief greenhouse gas responsible for man-made global warming.
“While good news for the environment, we certainly would not want to assume that this trend will continue and that we can simply relax,” said John Reilly, co-director of MIT’s Joint Program on the Science and Policy of Global Change.
Electric power plants spewed 141 million tons of carbon dioxide in April, the lowest for any month since April 1988, according to Energy Department figures. The power plants are responsible for about one-third of the country’s heat-trapping emissions.
April emissions peaked at 192 million tons in 2008 and dropped by 26 percent in seven years.
Carbon pollution from power plants hit their peak in August 2007 with 273 million tons; summer emissions are higher because air conditioning requires more power.
In past years, experts said the U.S. reduction in carbon dioxide pollution was more a function of a sluggish economy, but McFarland said that’s no longer the case.
“You don’t have a 27-year low because of an economic blip,” McFarland said. “There are more things happening than that.”
The price of natural gas has dropped 39 percent in the past year, he said. Federal analysts predict that this year the amount of electricity from natural gas will increase 3 percent compared to last year while the power from coal will go down 10 percent.
Those reductions were calculated before this week’s announcements of new power plant rules. The new rules aim to cut carbon pollution from electricity generators another 20 percent from current levels by 2030.
The pollution cuts in April are because efficiency has cut electricity demand and energy from non-hydropower renewable sources has more than doubled, said Princeton University professor Michael Oppenheimer.
“A factor behind all these trends is that the writing is on the wall about the future of coal and thus the future of U.S. carbon dioxide emissions,” Oppenheimer said in an email. “The regulatory noose is tightening and companies are anticipating a future with lower and lower dependence on fossil fuels and lower and lower carbon dioxide emissions.”

Gov. Brown wants to keep oil in the ground. But whose oil?
By David R. Baker, July 26, 2015 8:16pm
Even the greenest, most eco-friendly politicians rarely utter the words Gov. Jerry Brown spoke at the Vatican’s climate change symposium last week.
To prevent the worst effects of global warming, one-third of the world’s known oil reserves must remain in the ground, Brown told the gathering of government officials from around the world. The same goes for 50 percent of natural gas reserves and 90 percent of coal.
“Now that is a revolution,” Brown said. “That is going to take a call to arms.”
It’s an idea widely embraced among environmentalists and climate scientists. Burn all the world’s known fossil fuel supplies — the ones already discovered by energy companies — and the atmosphere would warm to truly catastrophic levels. Never mind hunting for more oil.
But it’s a concept few politicians will touch. That’s because it raises a question no one wants to answer: Whose oil has to stay put?
“They’ve all got their own oil,” said environmental activist and author Bill McKibben, who first popularized the issue with a widely read 2012 article in Rolling Stone. “Recognizing that you’ve got to leave your own oil — and not somebody else’s — in the ground is the next step.”
Take California.
No state has done more to fight global warming. By 2020, under state law, one-third of California’s electricity must come from the sun, the wind and other renewable sources. Brown wants 50 percent renewable power by 2030 and has called for slashing the state’s oil use in half by the same year.
But he has shown no interest in cutting the state’s oil production. He has touted the economic potential of California’s vast Monterey Shale formation, whose oil reserves drillers are still trying to tap. And he has steadfastly refused calls from within his own party to ban fracking.
“If we reduce our oil drilling in California by a few percent, which a ban on fracking would do, we’ll import more oil by train or by boat,” Brown told “Meet the Press.” “That doesn’t make a lot of sense.”
California remains America’s third-largest oil producing state, behind Texas and North Dakota. The industry directly employs 184,100 Californians, helps support an estimated 271,840 other jobs and yields $21.2 billion in state and local taxes each year, according to the Los Angeles County Economic Development Corporation.
‘Phasing out oil drilling’
Any governor, no matter how environmentally minded, would have a hard time turning that down. Even if many environmentalists wish Brown would.
“Just like we have a plan for increasing renewables, we need a plan for phasing out oil drilling in California,” said Dan Jacobson, state director for Environment California.
It’s difficult for politicians to even talk about something as stark as putting limits on pumping oil, he said.
“Solar and wind and electric cars are really hopeful things, whereas keeping oil in the ground sounds more like doomsday,” Jacobson said.
And yet, Jacobson, McKibben and now apparently Brown are convinced that most fossil fuel reserves must never be used.
The percentages Brown cited come from a study published this year in the scientific journal Nature. The researchers calculated that in order to keep average global temperatures from rising more than 2 degrees Celsius — 3.6 degrees Fahrenheit — above preindustrial levels, the world’s economy can pump no more than 1,100 gigatons of carbon dioxide into the atmosphere between 2011 and 2050. Burning the world’s known fossil fuel reserves would produce roughly three times that amount, they wrote.
Most governments pursing climate-change policies have agreed to aim for a 2-degree Celsius warming limit, although many scientists consider that dangerously high. So far, global temperatures have warmed 0.8 degrees Celsius from preindustrial times.
“The unabated use of all current fossil fuel reserves is incompatible with a warming limit of 2 degrees Celsius,” the study concludes.
Nonetheless, states, countries and companies with fossil fuel reserves all have an obvious and powerful incentive to keep drilling.
The market value of oil companies, for example, is based in part on the size of their reserves and their ability to find more. Activist investors warning of a “carbon bubble” in their valuations have pushed the companies to assess how many of those reserves could become stranded assets if they can’t be burned. The companies have resisted.
President Obama, meanwhile, has made fighting climate change a key focus of his presidency, raising fuel efficiency standards for cars, pumping public financing into renewable power and pushing for cuts in greenhouse gas emissions from power plants.
Cut demand or cut supply
But Obama has also boasted about America’s surging oil and natural gas production — and tried to claim credit for it. Last week, his administration gave Royal Dutch Shell the green light to hunt for oil in the Arctic Ocean. Keeping oil in the ground does not quite square with his “all of the above” energy policy, observers note. At least, not American oil.
“The same government that is working very hard to get a Clean Power Plan is allowing Shell to go exploring for hydrocarbons in the middle of nowhere, oil that may never be producible,” said climate activist and former hedge fund executive Tom Steyer, with audible exasperation.
He notes that Obama, Brown and other politicians intent on fighting climate change have focused their efforts on cutting the demand for fossil fuels, rather than the supply. Most of the policies that climate activists want to see enacted nationwide — such as placing a price on emissions of carbon dioxide and other greenhouse gases — would do the same, ratcheting down demand rather than placing hard limits on fossil fuel production.
“The political thinking is the market itself will take care of figuring out which fossil fuels have to stay in the ground,” Steyer said.
Some climate fights, however, have focused on supply. And again, the issue of whose fossil fuels have to stay put has played a part.
Opponents of the Keystone XL pipeline extension, for example, see blocking the project — which would run from Canada to America’s Gulf Coast — as a way to stop or at least slow development of Alberta’s enormous oil sands. James Hansen, the former head of NASA’s Goddard Institute for Space Studies, famously declared that fully developing the sands would be “game over for the climate.”
Obama has delayed a decision on the pipeline for years. Given America’s own rising oil production, rejecting a project that could be a boon for the Canadian economy would be difficult, analysts say.
“The message would be, ‘We’re not going to help you develop your resources — we’ll essentially raise the cost,’” said UC Berkeley energy economist Severin Borenstein. He is convinced that Canada will develop the tar sands, regardless.
“It’s become such a huge symbol that it’s impossible for Obama to make a decision on it,” Borenstein said. “I think he’s just going to run out the clock.”
