Managing director of Ebono Institute and major sponsor of The Generator, Geoff Ebbs, is running against Kevin Rudd in the seat of Griffith at the next Federal election. By the expression on their faces in this candid shot it looks like a pretty dull campaign. Read on

  • Global emissions exceeding ‘carbon budget’, PwC study finds.

     

    A fifth of that budget had been used up by 2008, they said, meaning the world is already 10% off the necessary trajectory to hit the target. The carbon “debt” in 2008 was equivalent to the joint emissions of the US and China.

    John Hawksworth, PwC’s head of macroeconomics, said: “Despite the widening consensus around the need to decarbonise, few countries are doing enough to live within our estimates of their carbon budgets. “If the world stays on this [course] we will have used up the entire global carbon budget for the first half of this century by 2034, 16 years ahead of schedule.”

    The report added that the G20 countries which account for over 80% of global emissions need to cut their carbon intensity – the amount of carbon dioxide emitted for each unit of GDP – by 35% by 2020, four times the rate achieved between 2000 and 2008.

    Global emissions from the use of energy need to peak by 2015 and fall back to 2009 levels by the end of the next decade, the report said.

    Leo Johnson, a PwC climate change partner, said previous inaction meant that much faster action was needed now: “If we had started on a low-carbon pathway in 2000, we would have needed to decarbonise at around 2% a year up to 2008. We managed only 0.8% in 2000-08. The result is we now need to decarbonise at a rate of 3.5% a year to get back on track by 2020 – four times more than we have managed at the global level since 2000.”

    The report said that Britain, one of the first countries to set a legally binding carbon budget, has recorded the eighth best performance in the G20 in the period. The UK is behind France and Germany but ahead of Italy, and around 6-7% off the required trajectory to meet its carbon budget by 2050.

    The EU as a whole, which claims leadership on the climate change agenda, is estimated to have been around 7% off target in 2008, having improved carbon intensity by 1.8% a year since 2000 compared to the 2.6% annually that would have been necessary to be on target.

    Only Russia reduced its carbon intensity by more than the budgeted amount since 2000, thanks to very rapid increases in energy efficiency, although it started from a very low base.

     

  • Antarctica may heat up dramatically as ozone hole repairs, warn scientists

     

     

    But John Turner of the British Antarctic Survey said scientists are now “very confident” that the anomaly had caused by the ozone hole above Antarctica. “We knew that, when we took away this blanket of ozone, we would have more ultra-violet radiation. But we didn’t realise the extent to which it would change the atmospheric circulation of the Antarctic.”

     

    These changes in weather have increased winds in the Southern Ocean region and meant that a large part of the continent has remained relatively cool compared with the western peninsula. But because the the CFC gasses that caused the ozone hole now been banned, scientists expect the damage to repair itself within the next 50-60 years. By then the cooling effect will have faded out and Turner said the Antarctic would face the full effects of global warming. This means an increase in average air temperatures of around 3C and a reduction in sea ice by around a third.

     

    The biggest threat to the continent comes from warming seas. Robert Binschadler, a glaciologist at Nasa who monitors Antarctic ice sheets, said: “The heat in the ocean is getting underneath the floating ice shelves, these floating fringes of the ice sheet that are hundreds of metres thick. That warm water is melting the underside of the ice shelf, reducing the buttressing effect.” Thinning of the ice shelf at the fringes leads to glaciers moving more quickly.

     

    The retreat of ice from Antarctica has contributed around 10% to global sea-level rise in recent decades. “The danger is that this warmer water will get under these ice shelves and cause the ice streams to get faster and feed ice out into the ocean,” said Turner.

     

    Published by the Scientific Committee on Antarctic Research (SCAR), a coalition of international experts that coordinates international research in the region, the report has been published to give negotiators in Copenhagen the most up-to-date science available. “Everything is connected — Antarctica may be a long way away but it is an important part of the Earth’s system,” said Colin Summerhayes, executive director of SCAR. “It contains 90% of the world’s ice, 70% of the world’s fresh water and that is enough, if it melts, to raise sea levels by 63m.”

     

    SCAR’s review also corroborated recent work by Stefan Rahmstorf, a climate scientist at the Potsdam Institute for Climate Impacts Research in Germany, that average sea-level rise will be closer to 1.4m by the end of the century. This is higher than the rise predicted by the Intergovernmental Panel on Climate Change (IPCC) in 2007, said Turner, because the IPCC’s forecasts did not include the impact of melting ice sheets on sea level rises. Many of the climate models used by the IPCC have also not taken the ozone hole into account in their simulations.

  • Copenhagen climate conference: Emission impossible

     

    Given what is at stake, essentially the future peace and prosperity of the planet, world leaders must now recognise that Copenhagen is the most important international gathering of our time. A strong political agreement can and must be reached in Copenhagen. There can be no excuses for failure.

    Recent weeks and months have shown country after country raising their ambitions on controlling emissions. It is now clear that if countries move together and they find ways to extend their action we could set the world on a responsible path. We can now see that it is possible to achieve an agreement that is effective, efficient and equitable. It will allow us to avoid the biggest risks of climate change, to overcome poverty worldwide and to usher in an exciting new era of prosperity based on a much more attractive and stronger form of economic growth – sustainable low-carbon growth.

    Through innovation and investment in greener and more energy efficient technologies in the next two or three decades, the transition to the low-carbon economy can be the most dynamic period of growth in economic history. And the low-carbon world we can create will also be quieter, cleaner, more energy-secure and more biologically diverse.

    For this to happen, there is a fierce urgency for leadership. The developed world in particular must face up to its responsibilities on both development and climate change. It will require radical change and significant resources. I believe we are now seeing strong momentum towards an agreement. Increasingly ambitions are being raised and shared. The developing world, if the rich world plays its part, will accelerate its actions and we can create an international collaboration which can transform the way the world works together.

    Three issues hold the key to agreeing an effective and equitable framework in Copenhagen. First, to have a reasonable – around 50% – chance of avoiding an increase in global average temperature of more than 2C above preindustrial levels, we must reduce annual worldwide emissions from the present level of just under 50bn tonnes of carbon-dioxide-equivalent to 44bn tonnes in 2020, much less than 35bn tonnes in 2030 and well below 20bn tonnes by 2050 – or as sometimes expressed, at least 50% below 1990 levels.

    Second, the need for national targets both to add up and to be fair means that the European Union, Japan and the US, should achieve emissions reductions of at least 80% by 2050, compared with 1990. Developing countries, including China and India, also need to limit the growth of, and then start to decrease, their emissions, but in ways that are consistent with their ambitions for continued economic growth and the reduction of poverty.

    Third, given the relative wealth of rich and poor countries, the rich countries responsibility for the bulk of past emissions, and the urgent need for action, developing countries must receive reliable and substantial support from the rich nations for their climate action plans. This is necessary both for their plans to reduce emissions and also to overcome the additional challenges that climate change will pose for their efforts to tackle poverty.

    Developed countries should show the extent of their commitment by providing $50bn per year by 2015, rising to $100bn in 2020, and progressing to around $200bn during the 2020s as effective low-carbon and adaptation programmes are developed and implemented.

    Crucially, financial support should be additional, beyond existing official development assistance. While these might sound like large sums, $50bn is around 0.1% of the likely gross domestic product of the rich countries in 2015, and is very small compared to the costs we will face if we do not secure a strong international agreement to tackle climate change. The immediate priorities for spending should be halting deforestation, supporting adaptation in Africa and other vulnerable nations, and supporting technological change throughout the developing world.

    We are seeking at Copenhagen an organisational framework with strong political commitment rather than a formal treaty. A formal treaty can follow in 2010 if the political framework is clear. But without such a framework, settled at the highest level, progress on a treaty or similar agreement will be impossible. Now is the time for heads of government to take charge – only they can forge such an agreement.

    Let us not allow mistrust, pessimism and lack of ambition to take us stumbling into profound dangers. Instead let us have real vision and leadership in both developing and developed countries which seize the opportunities offered by Copenhagen, for us, our children and future generations.

    George Monbiot

    “To be truly radical,” Raymond Williams wrote, “is to make hope possible rather than despair convincing”.

    Believe me I’m trying, but at the moment hope is hard to come by.

    A legally binding deal cannot now be struck at Copenhagen. The best that can happen is an outline agreement, which is firmed up next year. Even this would depend on the compliance of the US Senate. So far it has been hostile towards anything resembling an effective deal. As I write, Barack Obama still hasn’t proposed a number for US emissions cuts. He can’t make any firm commitment until the Senate sings, and the Senate won’t approve a climate change bill until the spring, if at all. I concentrate on the role of the US not because it is the only obstacle to a strong climate agreement (you should see what Canada has been up to) but because it has so far done more than any other nation to prevent global action from taking place. The Kyoto negotiations in 1997 were comprehensively trashed by a US delegation led by Al Gore.

    The EU had proposed a 15% cut against 1990 emissions levels by 2010. The US ensured that this was knocked down to 5.2% by 2012, with enough get-out clauses (emissions trading, joint implementation, the clean development mechanism) to render even that feeble target pretty well meaningless. After wrecking the treaty for everyone else, the Clinton government failed to ratify it, and George Bush later pulled out altogether.

    It wasn’t Gore’s fault: the Senate had already voted 95-0 to torpedo any treaty that failed to impose the same conditions on developing countries as it imposed on rich ones. The senators knew this was impossible for poorer countries to accept – in fact that was the point. The political impediments that made a deal with the US impossible in 1997 have scarcely changed.

    Until there is comprehensive campaign finance reform in the United States, almost any progressive measure remains out of reach. The US Senate is one of the most corrupt institutions of any democratic nation: most of the incumbents owe their seats to massive corporate funding; in return they must deliver the political goods to their sponsors. These are hopeless conditions in which to broker an agreement which has to defeat vested interests.

    Even if a legally binding treaty were to have been agreed at Copenhagen, getting it ratified and implemented before the Kyoto protocol runs out at the end of 2012 would have been a stretch. If it’s delayed until next year or beyond, the timetable becomes extremely tight. If world leaders can’t strike a deal this year, despite a massive build-up and intensive diplomatic activity, why should we expect them to be able to do so next year?

    I fear that the climate negotiations could go the same way as the Doha round of trade talks. These began in 2001. Eight years later there’s still no prospect of resolution. When the initial deadline had been missed and the red carpets were rolled up, governments lost interest and let the process drift. Delegates are already talking of moving the climate talks to Mexico next December after they fail in Copenhagen.

    This is what happened at Doha: the negotiations were reconvened at Cancún on the Mexican coast and vanished into thin air thereafter. Is “moving to Mexico” a diplomatic euphemism for abandonment?

    And there’s a more important deadline which looks ever more likely to be missed. The narrow window in which we could prevent more than 2C of global warming is closing fast. The longer a comprehensive agreement is delayed, the steeper the emissions cuts will have to be if we are to avoid climate breakdown. Beyond a certain point the scale of the cuts becomes politically, economically and technologically infeasible. That point must already be close.

    The postponement has an immediate consequence: no one will invest in low-carbon technologies unless they believe there’s a secure market. And no one will disinvest from fossil fuels unless they believe that they’ll cease to be profitable. If investors think the Kyoto protocol will run out before a new agreement begins, the bottom will fall out of the market for energy conservation and alternative technologies, setting the necessary transition back by years.

    So is there any hope that world leaders could regain their sense of urgency? If the prospect of a climate crash doesn’t motivate them, can anything? Perhaps there is one straw to cling to. In its new World Energy Outlook, the International Energy Agency (IEA) maintains that, to meet new demand and replace old equipment and exhausted reserves, the world will have to invest $25.6tn in energy supply infrastructure between now and 2030. The industrialised nations would also need to pay a fortune to the Opec countries to maintain their oil and gas supplies: the IEA predicts that the oil producers’ income will rise fivefold in this period, to $30tn. These costs will be much higher if oil supplies peak.

    If moving to a low-carbon economy looks implausible, so does maintaining the high-carbon economy. Whichever route is taken, staggering amounts of money need to be spent. As resources become harder to extract and concentrated in fewer countries, it shouldn’t be too difficult to persuade world leaders that the money might as well be spent on exploiting ambient energy, which will neither run out nor allow us to be held to ransom.

    That is the best I can do. Sorry.

  • Carbon trading could be worth twice that of oil in next decade

     

    The ETS market may see $3tn (£1.8tn) worth of transactions a year in the next decade or two, according to Andrew Ager, head of emissions trading at Bache Commodities in London, with it even being used as a hedge against falling equities or rising inflation. “It is still a relatively new industry with annual trades of around €300bn every year. But this could grow to around $3tn compared to the $1.5tn market there is for oil,” says Ager, who used to be a foreign currencies trader.

    The speed of that growth will depend on whether the Copenhagen summit gives a go-ahead for a low-carbon economy, but Ager says whatever happens schemes such as the ETS will expand around the globe.

    Last week Australia gave its strongest sign yet that it would establish its own trading market, while the US is moving towards a similar scheme in a bid to find market-based ways to accelerate the transition to a lower carbon economy. 

    Many political leaders, especially in industrialised countries, are enthusiastic: carbon markets hold the promise of cost-efficient emission cuts without the need for taxpayer funding. But their enthusiasm to place carbon markets at the heart of the Copenhagen treaty is matched by growing criticism of the concept, and not just from environmentalists opposed to free market solutions.

    Peter Voser, Shell’s chief executive, has called on governments to introduce a carbon tax or a minimum price for CO² because – as he told the Guardian – the ETS was failing to deliver sufficient incentives to kickstart expensive technologies such as carbon capture and storage (CCS).

    John Browne, a former boss of BP and an early ETS promoter, has also expressed reservations about such schemes, saying it was “wrong” to place all your faith in them. Vincent de Rivaz, chief executive of EDF Energy, warned of the dangers of a “sub-prime” crisis inside the ETS if complex financial instruments were created by market participants.

    The key problem seems to be that ETS carbon prices have remained resolutely low, thwarting low-carbon, high-cost investment. Carbon is currently trading at around $13 a tonne but many believe it needs to be $30, if not $50, to deliver a decisive boost for clean technologies such as wind, solar, CCS and nuclear power.

    The criticisms of environmentalists such as James Lovelock and Friends of the Earth (FoE) are far more fundamental. The basic charge is that the market has put millions of pounds into the pockets of some without making any real impact on carbon emissions.

    They accuse governments of being too lenient in the way they drew up the ETS: a cap that was far too loose, too many free permits, too few industries covered and poor monitoring of offset schemes that shift emissions to the developing world. If the carbon price is to rise in the next ETS phase, starting in 2013, much tighter rules will be needed.

    Henrik Hasselknippe, senior analyst at consultancy Point Carbon, argues the problems have been overplayed and the market – while not operating perfectly – has nonetheless come along way from a standing start.

    “Carbon prices have fallen due to the recession,” said Hasselknippe, adding that he was “convinced” that CDMs – clean development mechanism credits created under the Kyoto protocol – have led to real carbon reductions. However, some reports claim that a third to two-thirds of CDMs do not reduce emissions.

    Alexandria Galin, a policy manager for the Carbon Markets and Investors Association, dismisses suggestions that the market had been taken over by speculators, as claimed by FoE. “Financial institutions participate in the market largely on behalf of businesses that do not have the capacity or expertise to do it themselves. Furthermore there are no ‘complex’ instruments creating ‘shadow finance’,” she said.

    Agers agrees, saying his company largely provides advice or trading on behalf of power companies and others who need to hedge their legitimate carbon risks.

    He admitted that he is in many ways like any other City trader with a decent salary, nice flat and sports car to prove it. But working in the carbon field has rubbed off a little on his lifestyle: he claims to have energy-efficient lightbulbs in his home and to offset the petrol he uses driving his car to watch West Ham football team on a Saturday.

    The arguments

    Carbon market

    For

    • Guarantees specific carbon cut by setting overall cap

    • Delivers maximum cuts in carbon emissions at minimum cost

    • No taxpayer funding

    Against

    • Volatile or low price of permits deters investment

    • Prone to political interference, complex and provides no incentive for individuals to act

    Carbon taxes

    For

    • Clear, simple, covers everyone

    • Relatively low implementation costs

    Against

    • Hits motoring and flying directly

    • Cannot deliver specific emissions cut – depends on consumption levels

    Regulation

    For

    • Cannot be avoided by finding loopholes

    • Can drive big changes where markets cannot, such as energy efficiency

    Against

    • Businesses rail against red tape

    • Expensive to implement

  • Western lifestyle unsustainable, says climate expert Rajenda Pachauri

     

    “Today we have reached the point where consumption and people’s desire to consume has grown out of proportion,” said Pachauri. “The reality is that our lifestyles are unsustainable.”

    Among the proposals highlighted by Pachauri were the suggestion that hotel guests should be made responsible for their energy use. “I don’t see why you couldn’t have a meter in the room to register your energy consumption from air-conditioning or heating and you should be charged for that,” he said. “By bringing about changes of this kind, you could really ensure that people start becoming accountable for their actions.”

    Pachauri also proposed that governments use taxes on aviation to provide heavy subsidies for other forms of transport. “We should make sure there is a huge difference between the cost of flying and taking the train,” he said. Despite the fact that there is often little benefit in time and convenience in short-haul flights, he said people were still making the “irrational” choice to fly. Taxation should be used to discourage them.

    He dismissed suggestions that the actions he was advocating were insignificant next to the decisions that would be made at the UN’s climate summit which opens in Copenhagen in seven days’ time. “In a democracy, governments will ultimately respond to what the people want,” he said. “If the people have a strong desire which can be demonstrated through their actions, as well as their vote at the time of elections, you can bring about a major shift in policy.”

    Pachauri caused controversy last year by advocating, in an interview with the Observer, that people should eat less meat because of the levels of carbon emissions associated with rearing livestock. He is scheduled to deliver a keynote speech at the opening session of the Copenhagen summit.

    He said the opening bids from China and the US on emissions – announced last week – had given hope that a deal could be reached in Copenhagen, even if some details would have to be filled in later. “I think it provides momentum to the whole negotiations,” he said.

    Pachauri was speaking to the Observer before a public discussion at the Wellcome Collection in Euston with the philosopher AC Grayling yesterday. It will be broadcast by the BBC World Service on Wednesday.

    He said that he also believed car use would have to be “curbed”: “I think we can certainly use pricing to regulate the use of private vehicles.” He added he was a supporter of former London mayor Ken Livingstone‘s plan to increase the congestion charge to £25 for the most polluting vehicles. The proposal was dropped by Boris Johnson and the charge currently stands at £8. Pachauri also denounced the practice in some restaurants of providing iced water to customers who had not ordered it. “It is just an enormous amount of waste that we don’t even think about,” he said.

    Ultimately, Pachauri said the value shift that was needed would take a generation to take hold. “I think the section of society that will make it happen is essentially young people. I think they will be far more sensitive than adults, who have been corrupted by the ways we have been following for years now.”

  • Searching for a miracle

     

    Perhaps the most significant limit to future energy supplies is the “net energy” factor—the requirement that energy systems yield more energy than is invested in their construction and operation. There is a strong likelihood that future energy systems, both conventional and alternative, will have higher energy input costs than those that powered industrial societies during the last century.We will come back to this point repeatedly.

    The report explores some of the presently proposed energy transition scenarios, showing why, up to this time, most are overly optimistic, as they do not address all of the relevant limiting factors to the expansion of alternative energy sources. Finally, it shows why energy conservation (using less energy, and also less resource materials) combined with humane, gradual population decline must become primary strategies for achieving sustainability.

    ***

    The world’s current energy regime is unsustainable. This is the recent, explicit conclusion of the International Energy Agency1, and it is also the substance of a wide and growing public consensus ranging across the political spectrum. One broad segment of this consensus is concerned about the climate and the other environmental impacts of society’s reliance on fossil fuels.The other is mainly troubled by questions regarding the security of future supplies of these fuels—which, as they deplete, are increasingly concentrated in only a few countries.

    To say that our current energy regime is unsustainable means that it cannot continue and must therefore be replaced with something else.However, replacing the energy infrastructure of modern industrial societies will be no trivial matter. Decades have been spent building the current oil-coal-gas infrastructure, and trillions of dollars invested. Moreover, if the transition from current energy sources to alternatives is wrongly managed, the consequences could be severe: there is an undeniable connection between per-capita levels of energy consumption and economic well-being.2 A failure to supply sufficient energy, or energy of sufficient quality, could undermine the future welfare of humanity, while a failure to quickly make the transition away from fossil fuels could imperil the Earth’s vital ecosystems.

    Nonetheless, it remains a commonly held assumption that alternative energy sources capable of substituting for conventional fossil fuels are readily available—whether fossil (tar sands or oil shale), nuclear, or a long list of renewables—and ready to come on-line in a bigger way. All that is necessary, according to this view, is to invest sufficiently in them, and life will go on essentially as it is.

    But is this really the case? Each energy source has highly specific characteristics. In fact, it has been the characteristics of our present energy sources (principally oil, coal, and natural gas) that have enabled the building of a modern society with high mobility, large population, and high economic growth rates. Can alternative energy sources perpetuate this kind of society? Alas, we think not.

    While it is possible to point to innumerable successful alternative energy production installations within modern societies (ranging from small homescale photovoltaic systems to large “farms” of threemegawatt wind turbines), it is not possible to point to more than a very few examples of an entire modern industrial nation obtaining the bulk of its energy from sources other than oil, coal, and natural gas. One such rare example is Sweden, which gets most of its energy from nuclear and hydropower. Another is Iceland, which benefits from unusually large domestic geothermal resources, not found in most other countries. Even in these two cases, the situation is more complex than it appears.The construction of the infrastructure for these power plants mostly relied on fossil fuels for the mining of the ores and raw materials, materials processing, transportation, manufacturing of components, the mining of uranium, construction energy, and so on. Thus for most of the world, a meaningful energy transition is still more theory than reality. But if current primary energy sources are unsustainable, this implies a daunting problem. The transition to alternative sources must occur, or the world will lack sufficient energy to maintain basic services for its 6.8 billion people (and counting).

    Thus it is vitally important that energy alternatives be evaluated thoroughly according to relevant criteria, and that a staged plan be formulated and funded for a systemic societal transition away from oil, coal, and natural gas and toward the alternative energy sources deemed most fully capable of supplying the kind of economic benefits we have been accustomed to from conventional fossil fuels.

    By now, it is possible to assemble a bookshelf filled with reports from nonprofit environmental organizations and books from energy analysts, dating from the early 1970s to the present, all attempting to illuminate alternative energy transition pathways for the United States and the world as a whole.These plans and proposals vary in breadth and quality, and especially in their success at clearly identifying the factors that are limiting specific alternative energy sources from being able to adequately replace conventional fossil fuels.

    It is a central purpose of this document to systematically review key limiting factors that are often left out of such analyses.We will begin that process in the next section. Following that, we will go further into depth on one key criterion: net energy, or energy returned on energy invested (EROEI).This measure focuses on the key question: All things considered, how much more energy does a system produce than is required to develop and operate that system? What is the ratio of energy in versus energy out? Some energy “sources” can be shown to produce little or no net energy. Others are only minimally positive.

    Unfortunately, as we shall see in more detail below, research on EROEI continues to suffer from lack of standard measurement practices, and its use and implications remain widely misunderstood. Nevertheless, for the purposes of large-scale and long-range planning, net energy may be the most vital criterion for evaluating energy sources, as it so clearly reveals the tradeoffs involved in any shift to new energy sources.

    This report is not intended to serve as a final authoritative, comprehensive analysis of available energy options, nor as a plan for a nation-wide or global transition from fossil fuels to alternatives. While such analyses and plans are needed, they will require institutional resources and ongoing reassessment to be of value.The goal here is simply to identify and explain the primary criteria that should be used in such analyses and plans, with special emphasis on net energy, and to offer a cursory evaluation of currently available energy sources, using those criteria.This will provide a general, preliminary sense of whether alternative sources are up to the job of replacing fossil fuels; and if they are not, we can begin to explore what might be the fall-back strategy of governments and the other responsible institutions of modern society.

    As we will see, the fundamental disturbing conclusion of the report is that there is little likelihood that either conventional fossil fuels or alternative energy sources can reliably be counted on to provide the amount and quality of energy that will be needed to sustain economic growth—or even current levels of economic activity—during the remainder of the current century.

    This preliminary conclusion in turn suggests that a sensible transition energy plan will have to emphasize energy conservation above all. It also raises questions about the sustainability of growth per se, both in terms of human population numbers and economic activity.
