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.

More information about each state’s energy-related CO2 emissions is available in EIA’s report, Energy-Related Carbon Dioxide Emissions at the State Level, 2000-13.

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%.

Paris climate talks: Developed countries must do more than reduce emissions

By Shyam Saran, 23 November 2015 05.35 EST  –  Saran is a former foreign secretary of India. He was India’s chief negotiator on climate change from 2007 to 2010

We are only days away from the climate change summit in Paris. Several world leaders are likely to be present to applaud a successful outcome, which is virtually guaranteed since the bar has been set so low in terms of effort expected from the major industrialized economies.

Under the UN process which the negotiations have been taking place, countries are required only to present their climate pledges (known as Intended Nationally Determined Contributions, or INDCs, which are voluntary and subject to an international review but with no strict compliance procedure.

It is this pledge and review system which will become the template for future climate change action. Past experience shows that such weak international regimes, which posit only a best endeavour commitment, rarely deliver expected results.

The UN recently reported that aggregating all the INDCs so far, the world would be on an a trajectory of 2.7C, when a 2C rise is already the limit of safety defined by scientists.

What many people fail to realize is that global warming is the consequence of the stock of greenhouse gas emissions, chiefly CO2, which has accumulated in the Earth’s atmosphere as a result of fossil fuel based industrial activity in the industrialized countries of the world.

This is the reason why the UN recognizes the historical responsibility of the developed countries in causing global warming even though current industrial activity in major developing countries such as China and, to a much lesser extent, India is adding incrementally to that stock.

If developed countries do not make significant and absolute reductions in their emissions there will be a progressively smaller carbon space available to accommodate the development needs of developing countries. There is a difference between the emissions of developing countries which are “survival” emissions and those of developed countries which are in the nature of “lifestyle” emissions. They do not belong to the same category and cannot be treated on a par.

To blur this distinction is to accept the argument that because “we got here first, so we get to keep what we have, while those who come later must stay where they are for the sake of the saving the planet from the threat of climate change.” Far from accepting their historical responsibility developed countries are instead trying to shift the burden on to the shoulders of developing countries.

This they have been doing by keeping attention focused on current emissions while ignoring the source of the stock of emissions in the atmosphere. A sustainable and effective climate change regime cannot be built on the basis of such inequity.

One often hears the argument that it is all very well to preach equity but given the planetary emergency the world faces from the threat of climate change we must set aside the equity principle in the interests of humanity as a whole. This is a wholly specious and self serving argument. It reflects the sense of entitlement to an affluent lifestyle, based on energy intensive production and consumption, while denying the even modest aspirations of people in developing countries.

In a densely interconnected and globalised world, it will be impossible to maintain islands of prosperity in an ocean of poverty and deprivation. It is not that developing countries are claiming the right to spew as much carbon as possible into the atmosphere without regard to the health of the planet.

As the main victims of climate change– the impacts of which they are already suffering – they have a much bigger stake in dealing with this challenge. They are, in fact, doing much more than most developed countries, to adopt energy frugal methods of growth, conserving energy, promoting renewable power and limiting waste within the limits of their own resources.

They could do much more if they had access to finance, technology and capacity building from developed countries, a commitment which is incorporated in the UN. Success may elude Paris if developed countries continue to evade their responsibility to provide adequate financial resources and transfer appropriate technologies to developing countries to enable them to enhance their own domestic efforts.

Climate negotiations have become less about meeting an elemental challenge to human survival and more about safeguarding narrowly conceived economic self interests of nations. These are negotiations conducted in a competitive frame, where each party gives as little as possible and extracts as much as possible. The inevitable result is a least common denominator result and this is what is expected at Paris.

Imagine if each country came with the intention to contribute as much as it can and take away as little benefit to itself as possible, because we are all faced with an urgent and global challenge. We would then get a maximal outcome – which is what the world requires if it has to escape the catastrophic consequences of climate change. The negotiating dynamic may change dramatically.

The leaders can capture the imagination of people around the world if they explicitly acknowledge the seriousness of the threat we all confront and commit themselves to a global collaborative effort to deal with it based on the principle of equitable burden sharing.

Countries can then contribute according to their capacities and resource availability and I have no doubt that emerging countries such as India, China or Brazil will be enthusiastic participants in such initiatives. Even if we are unable at this stage to go beyond the INDCs which have already been submitted the adoption of these initiatives may reassure the world that a new and more promising process has been set in motion to deliver a more sustainable future for our common home.

Study finds the warmer it gets, the more world economy hurts

With each degree, unrestrained global warming will singe the overall economies of three quarters of the nations in the world and widen the north-south gap between rich and poor countries, a new economic and science study found. Compared to what it would be without more global warming, the average income globally will shrivel 23 percent at the end of the century if heat-trapping carbon dioxide pollution continues to grow at current trajectories, according to a study published Wednesday in the scientific journal Nature.

WASHINGTON (AP) — With each upward degree, global warming will singe the economies of three-quarters of the world’s nations and widen the north-south gap between rich and poor countries, according to a new economic and science study.

Compared to what it would be without more global warming, the average global income will shrivel 23 percent at the end of the century if heat-trapping carbon dioxide pollution continues to grow at its current trajectory, according to a study published Wednesday in the scientific journal Nature.

Some countries, like Russia, Mongolia and Canada, would see large economic benefits from global warming, the study projects. Most of Europe would do slightly better, the United States and China slightly worse. Essentially all of Africa, Asia, South America and the Middle East would be hurt dramatically, the economists found.

“What climate change is doing is basically devaluing all the real estate south of the United States and making the whole planet less productive,” said study co-author Solomon Hsiang, an economist and public policy professor at the University of California Berkeley. “Climate change is essentially a massive transfer of value from the hot parts of the world to the cooler parts of the world.”

“This is like taking from the poor and giving to the rich,” Hsiang said.

Lead author Marshall Burke of Stanford and Hsiang examined 50 years of economic data in 160 countries and even county-by-county data in the United States and found what Burke called “the goldilocks zone in global temperature at which humans are good at producing stuff” — an annual temperature of around 13 degrees Celsius or 55.4 degrees Fahrenheit, give or take a degree.

For countries colder than that economic sweet spot, every degree of warming heats up the economy and benefits. For the United States and other countries already at or above that temperature, every degree slows productivity, Burke and Hsiang said.

The 20th-century global average annual temperature is 57 degrees, or 13.9 degrees Celsius, according to the National Oceanic and Atmospheric Administration. Last year — the hottest on record — was 58.24 degrees and this year is almost certain to break that record, according to NOAA. Burke and Hsiang use different population-weighted temperature figures than NOAA calculates.

But the U.S. economy is humming despite the heat. When asked how that can be so, Burke said there were many factors important for growth beyond just temperature. He said one year’s temperature and economic growth in one nation isn’t telling. Instead, he and Hsiang looked at more than 6,000 “country-years” to get a bigger picture.

Burke compared the effect of global warming on economies to a head wind on a cross-country airplane flight. The effects at any given moment are small and seemingly unnoticeable but they add up and slow you down.

While it is fairly obvious that unusual high temperatures hurt agriculture, past studies show hot days even reduce car production at U.S. factories, Burke said.

“The U.S. is really close to the global optimum,” Burke said, adding that as it warms, the U.S. will fall off that peak. The authors calculate a warmer U.S. in 2100 will have a gross domestic product per person that’s 36 percent lower than it would be if warming stopped about now.

But because the U.S. is now at that ultimate peak, there’s greater uncertainty in the study’s calculations than in places like India, Pakistan, Vietnam, Nigeria and Venezuela where it’s already hot and there’s more certainty about dramatic economic harm, Hsiang said.

The authors’ main figures are based on the premise that carbon dioxide emissions will continue to rise at the current trajectory. But countries across the world are pledging to control if not cut carbon pollution as international leaders prepare for a summit on climate change in Paris later this year. If the current pledges are kept, the warming cost in 2100 will drop from 23 percent to 15 percent, Burke said.

Gary Yohe, an environmental economist at Wesleyan University in Connecticut, praised the study as significant and thorough, saying Burke and Hsiang “use the most modern socio-economic scenarios.” But Richard Tol, an economist at the University of Sussex in England, dismissed the study as unworthy to be published in an economics journal, saying “the hypothesized relationship is without foundation.”

Other experts found good and bad points, with MIT’s John Reilly saying it will spark quite a debate among economists.
