Australia Overtakes the US as Leader in CO2 Emissions per Person

After being recently replaced by China as the number one greenhouse gas polluter in the world, the US has now been surpassed by Australia as the leading nation in CO2 emissions on a per capita basis. According to Reuters, the US emissions of 19.8 tons per capita annually was only good for second place, with Australia taking over the lead with 20.6 tons. In third place was Canada at 18.8 tons. Per capita emissions have become a major sticking point in the negotiations on a climate treaty to replace the Kyoto Protocol which expires in 2012 as developing countries, particularly China and India, have been arguing that developed countries should assume most of the burden for reducing emissions since on a per capita basis their emissions are several times higher. However, the British economist Nicholas Stern, who wrote an influential report on climate change, recently noted in a talk given in Beijing, China, that although China’s emissions on a per capita basis are much lower than those of developed countries, there were 13 provinces, regions, and cities in China that actually had higher emissions per capita than France and 6 with higher emissions than Britain. According to the AFP news agency, Stern has calculated that for the risk of dangerous climate change to be minimized emissions would need to be reduced to 2 tons per person worldwide. Unfortunately, with millions of people in China and India rapidly adopting Western lifestyles and many developed countries including the US refusing to commit to the necessary reductions in carbon dioxide emissions by 2020 called for by the leading climate scientists the prospects for minimizing the risks of dangerous climate change appear to be rapidly diminishing.

China May Be Incapable of Lowering Carbon Dioxide Emissions

For those getting optimistic that with a new carbon-cutting U.S. administration in place there is good reason to believe that the world’s emissions of carbon dioxide my soon be dropping to levels that can combat global warming a reality check comes in the form research results from Dabo Guan from the University of Cambridge and colleagues from the U.S. and Norway who have concluded that China, which contributes about one fourth of all greenhouse gas emissions today, may not have the capability to cut emissions during the next two decades. An article posted on Spiegel Online says that these scientists have concluded that even with substantial use of energy efficiency measures and the latest energy technology carbon dioxide emissions for China will increase by 80% from 2002 levels by 2030. This is based on a projection that demand for electricity would triple in China as more roads and airports are built and the Western lifestyle with all of its electrical appliances and electronic gadgets continues to spread. It was assumed that the Chinese would use coal sequestration and storage for every new coal plant and that this technology would actually work, which is far from proven. It was also assumed unrealistically that by 2030 China would get 40% of its electricity from renewable sources such as wind and hydro; no country has achieved that yet. Is there any hope? Guan’s advice is that the Chinese should not follow the typical energy-intensive lifestyles of people in the West. Unfortunately, it is very hard to imagine that advice being followed.

China’s Carbon Dioxide Emissions Are Greatly Exceeding Predictions

The UN’s Intergovernmental Panel on Climate Change predicted that from 2004 through CO2 emissions would increase annually by 2.5 to 5% in the region of Asia that includes China, but according to a report in Reuters economics researchers from the US publishing in the Journal of Environmental Economics and Management say that the annual rate of increase for China over this time period will be at least 11%. According to the researchers the increase in CO2 emissions from China will greatly exceed all the reductions pledged by the countries participating in the Kyoto Protocol for the years 2008 to 2012. One of the researchers said that "What we're finding…is that the emissions growth rate is surpassing our worst expectations, and that means the goal of stabilizing atmospheric CO2 is going to be much, much harder to achieve."

Much, much harder to achieve may even be an understatement. Perhaps impossible to achieve is more accurate. With all the positive reports about increasing numbers of wind turbines and solar installations being in the news it seems that there is some reason for optimism that atmospheric CO2 levels can kept to a level that does not precipitate catastrophic climate change, but this report on China is quite a reality check.

Bill McKibben Calls for 350ppm Carbon Dioxide Target

Environmental author and activist Bill McKibben, who launched the Step It Up campaign last year, has revealed the next phase of his plan to fight global warming with local activism. The Brattleboro Reformer reports that McKibben told a group of local activists that this next phase will call for a target of 350 parts per million of atmospheric carbon dioxide. As things stand now we are at about 385ppm and heading upward at about 2ppm per year. He is calling his plan 350. McKibben said that “What we need is people in their own communities to take that number and spread it, with music, with art, and take pictures and get it back into that centralized area.” Unlike his Step It Up campaign which was limited to the United States, this new 350 campaign he envisions as international. McKibben clearly understands the precarious situation that excessive emissions of greenhouse gases from human sources has caused saying that “We are in a big, freaking hole and there’s absolutely no guarantee that we are going to get out of it.” So, it is on to 350.

James Hansen Says CO2 Must Be Reduced to 350ppm

The aim of most people fighting global warming is to keep atmospheric carbon dioxide levels from increasing above 450ppm, which is approximately 65ppm above today’s levels. This target has been advocated by climate scientist James Hansen, the head of NASA’s Goddard Institute for Space Studies, and has been also been advocated by the UN’s Intergovernmental Panel on Climate Change. But Hansen is now saying that the target is too high. In an article in the British newspaper The Sunday Times he says:

“If humanity wants to preserve a climate resembling that in which civilisation developed, then the palaeoclimate evidence and ongoing climate change suggest CO2 must be reduced from its current level to between 300-350ppm. A 350ppm target is only achievable by phasing out coal use….We need a moratorium on the construction of coal-fired power plants and we must phase out the existing ones within two decades.”

If Hansen is right, it appears we will just have to accept a planet that does not resemble the one we are familiar with. Limiting CO2 to 450ppm appears to be an almost impossible task, particularly with China and India counting on coal to lift hundreds of millions of people out of a meager existence. Reducing CO2 to 350ppm or even lower doesn’t seem to be a feasible goal. It is hard to imagine the world only 20 years from now without any operating coal-fired plants. According to the article, Hansen will support his view of setting a lower target in a research paper. Until that paper is published and other scientists have a chance to review it is unlikely that the target of 450ppm will revised. However, perhaps we should be prepared for an even gloomier view of the possibility of extracting ourselves out of our global warming predicament than we now have.

Asian Growth Blamed for Record Carbon Dioxide Levels

Reports from a Norwegian station in the Arctic show that carbon dioxide measurements have reached a new record of about 394 parts per million (these measurements are higher than the most quoted measurements obtained in Hawaii). An article in the Internet Edition of China Post says that Kim Holman, director of the Norwegian Polar Institute, attributes the increase in carbon dioxide emissions to growing Asian economies. Holman says this growth is connected to a recent reduction in industrial efficiency as more carbon is being emitted per dollar of economic output, a trend which is opposite to that which took place over many preceding years. Holman is quoted in the article as saying that “the affluent world wants to buy cheap stuff and we buy it…from the inefficient old-fashioned technology that we have got rid of.” As long as people think of themselves as consumers rather than citizens they will prefer the “cheap stuff” to what makes sense in terms of protecting the environment, furthering human rights, etc. American political scientist Benjamin Barber addresses this problem in his 2007 book Consumed: How Markets Corrupt Children, Infantilize Adults, and Swallow Citizens Whole. He puts the blame not those buying products but on the manufacturers who are selling products.

Fears Mount that $2,500 Car Will Drive Up Global Temperatures

What if someone could create a car that was so cheap that hundreds of millions of people in developing countries could afford to drive a car instead of a bicyle, motor scooter, or motorcycle. Meet Ratan Tata, the head of the Tata Group in India. As reported in The Washington Post, Tata just introduced his new supercheap car called the Nano at the Delhi Auto Expo. Although the car is no gas guzzler, averaging about 50 miles per gallon, traveling in one of these things will put out a lot more carbon dioxide than a scooter or motorcycle. According to Tata for there is only 1 car for every 1,000 Indians whereas there are 750 cars for every 1,000 Americans. Clearly we Americans are in a difficult position trying to put a negative spin on the Tata Nano. With our three-car garages remaining stuffed with SUVs and performance sedans while climate scientists are screaming that we have to reduce carbon emissions or face catastophe we are in no position to expect the Indians or Chinese to listen to us proclaim the advantages of the bicycle over the automobile.

IPPC Leader Says Developing Countries Need Increase in Carbon Emissions

Rajendra Pachauri, the head of the UN’s Intergovernmental Panel on Climate Change (ICPCC) recently said when the IPCC released its fourth report of the year that "If there's no action before 2012, that's too late. What we do in the next two to three years will determine our future. This is the defining moment." It is hard to but it better than that. However, it appears the “we” which Pachauri refers to includes only the developed countries because in a statement made at the world conference on climate change being held in Bali, Indonesia he said that to get millions people out of poverty developing nations need to boost carbon emissions. In an AFP article Pachauri is quoted as saying that “If you have the case of India, a half billion people who do not even have electricity, what mitigation (of carbon emissions) can you carry out?”

Pachauri’s view is opposite to the conclusion from a report by the Center for Global Development (CGD) which I described yesterday. That report said that an increase in carbon emissions by developing counties to get large populations out of poverty would result in catastrophic climate change regardless of what developed countries did. Perhaps the president of the CGD, Nancy Birdsall, has the answer to this dilemma when she says as reported in DailyIndia that “To avoid a shared global disaster, we in the rich countries need to cut our own emissions quickly and do much more to help developing countries shift to a low-carbon future while at the same time meeting the just aspirations of their people for a better life.” The latter task is likely to be a tough sell in the developed countries but it may be our best hope.

Report Says Developing Countries Need to Curtail Carbon Emissions

The idea that severe climate change can be prevented by developed countries sharply cutting back on carbon emissions while developing countries continue to increase emissions to lift their populations out of poverty has been dealt a blow by a report from the Center for Global Development which concluded that the developing countries too must back and soon. According to DailyIndia.com, the report, which has the long title of “Another Inconvenient Truth: A Carbon-Intensive South Faces Environmental Disaster, No Matter What the North Does,” found that even if emissions from the North suddenly dropped to zero emissions from the South alone would drive atmospheric carbon dioxide levels past 450 ppm by 2060, generally regarded as the point where climate change has catastrophic consequences. The lead author, David Wheeler, is quoted as saying that “Our results reveal the dangerous fallacy in the notion that the South can utilize carbon-intensive growth to dramatically increase incomes--a kind of last-minute, fossil-fueled development push--before the onset of catastrophic climate change.” To make matters worse, Wheeler claims that the conclusions of the report are on the conservative side because it only included carbon dioxide emissions, leaving out other greenhouse gases and the effects of positive feedbacks. All in all, it is a grim picture that emerges as the meeting about what do to after the Kyoto Protocol ends takes place in Bali, Indonesia.

Ships Are Outpolluting Planes

The was a large global warming protest recently at London’s Heathrow Airport but so far there has been no such protests at any shipping port. Maybe there should be. A shipping industry group called Intertanko has released a report which says that carbon dioxide emissions from shipping are now almost double that from aviation. In an article on the report from ABC News in Australia it says that Intertanko attributes the growth in carbon dioxide emissions from shipping to an increase in global trade and the use of more fuel to speed up the delivery of goods.

Concerns about shipping in this country have largely focused on terrorism. In the US critics of the government’s security measures have complained that a large percentage of shipping containers that arrive in this country are never checked. There has been little concern over the amount of carbon dioxide released getting the containers over here. This report should finally place shipping under the global warming microscope.

Southern Utilities Cling to Coal Burning

We know historically that the South has been extremely slow to change and in fact has been so slow that it has been forced to change when it came to slavery and segregation. It appears that this pattern of resisting change is continuing when it comes to switching from coal burning to renewable energy sources. According to an article from the Associated Press, whereas nearly half of the states now have adopted mandates requiring electric utilities to produce a specific percentage of electricity from renewables, Texas is the only state in the South with such a mandate. Moreover, half of the votes in the Senate to defeat federal legislation to require 15% of electricity to come from renewables were cast by senators from southern states.

A good appreciation of the coal-burning situation in the South can be gained by watching the film Kilowatt Ours. The film shows how burning coal in the South has resulted in the Great Smokey Mountain National Park often being filled with haze instead of usually offering crystal clear views of distant mountains as in the past and how the need for coal in the South, which uses more coal than the national average for generating electricity, leads to the disgraceful practice of mountaintop mining in West Virginia.

The AP article says that the US Environmental Protection Agency ranks three southern utilities—Southern Co., Duke Energy, and the Tennessee Valley Authority—among the top four greenhouse gas emitting utilities in the US. The number one emitter, Southern Co., doesn’t even appear to admit that emissions of carbon dioxide are related to global warming based on statements such as the following by senior executive Chris Hobson who was quoted in the article as saying:

"If we are irrational about it and we cripple our economy or cripple our industry and we realize carbon dioxide wasn't the source of the problem, then we'll be real regretful."

Maybe someone at Southern Co. should read the latest reports from the Intergovernmental Panel on Climate Change. If they did they would learn that carbon dioxide and other greenhouse gases emitted from human sources are the source of the problem. Scientists will never say they are 100% sure of a conclusion but this statement was about as close as they will ever get. The Old South may be mostly gone but the New South needs to transform into the Green South.
