10:10 campaign bracelets coming out of the machine that is recycling them from an old 747.
10:10, a campaign to get individuals and organisations to reduce their emissions by 10% in 2010 is launched today, 1 September. The idea is simple and has proved surprisingly easy to communicate so far. Of course it has helped that the human tornado Franny Armstrong has been pushing it.

This article refers to the UK proposals made in July 2009. The actual feed-in tariffs will be more generous and the new rates are discussed in a follow up article here.
After months of deliberation, the UK government has announced a range of illustrative figures for feed-in tariffs (FiTs). FiTs are fixed payments made to the owners of small generating stations for the electricity that they export to the grid. Micro-generators need high payments to justify their expensive investment in buying and installing green generation.

Small heat pumps are increasingly used to provide space and water heating in UK homes. This trend is strongly encouraged by policy-makers and the government’s proposed Renewable Heat Incentive will add further financial support. The enthusiasm for this expensive technology should be moderated: for a home on the mains gas network, the savings in money will be small. Carbon benefits are probable but far from guaranteed. Moreover, air source heat pumps are unlikely to be able to heat many older homes effectively. Government, manufacturers, and installers need to be very much more cautious in encouraging the use of heat pumps and should use far more conservative payback assumptions. Heat pumps will eventually be a good investment for homeowners but probably not yet.

Most governments in the developed world were elected on platforms that promised aggressive policies on greenhouse gas emissions. The reality has not matched the commitments made. The reasons for this are multitudinous and no one should ever underestimate the difficulties of weaning advanced societies off the use of cheap and convenient access to fossil fuels. But in addition to the standard reasons for slow progress we can see a large number of obstacles that spring from human psychology. In particular, some of the resistance to aggressive action on climate seems to spring from mental attitudes that may have helped us survive as a species in the past. Perhaps politicians intuitively recognise the existence of these barriers. So they continue to say that climate change is the most important problem facing humanity at the same time as adding new runways to the local airport or sanctioning the development of new coal-fired power stations.

The government wants to emphasise the affordability of climate change mitigation. It produces low estimates of the cost of low-carbon technologies. In the recent 2009 budget documents, the government estimated a cost of 1% of GDP to meet the tough new 2020 targets. In his pronouncement on carbon capture at coal-fired power stations, energy and climate change secretary Ed Miliband later said that his proposals will add 2% to electricity bills.
Are these numbers reasonable? Professor Sir David King, the former chief scientific adviser, says no. In a BBC interview of 26 April, he indicates that he thinks that the cost of reducing the UK’s emissions is much higher than the government indicates but also that the financial implications of not dealing with the climate change threat are far higher than even Nick Stern suggests.

The Committee on Climate Change says the most important prospective source of cuts in greenhouse gases lay in the ‘decarbonisation’ of electricity generation. Photograph: Graham Turner/Guardian.
The budget confirmed the acceptance of the Committee on Climate Change‘s recommendation for carbon emissions in 2020. The UK will have to reduce its CO2 output by about 110m tonnes by 2020, equivalent to a 21% reduction on actual emissions in 2005 (and 34% on the 1990 figure). The proposed rate of emissions reduction is far faster than the UK has achieved thus far and the chancellor’s budget shows the government has started to recognise the scale of the challenge.

Gordon Brown says he wants two or three cities to trial electric vehicles before the end of next year. After many false dawns, are we finally about to see the era of the battery car?

The tiny pores in a piece of biochar. Image source: BEST Energies.
George Monbiot wrote about the carbonisation of organic matter in the Guardian last month (‘Woodchips with everything. It’s the Atkins plan of the low-carbon world’, Tuesday 24 March 2009), saying it was yet another miracle cure for the climate problem. And, like previous miracle cures, he said ‘biochar’ would turn out to be a dangerous delusion. It would deflect attention from taking real action on climate change. Parts of the planet would be turned into vast forest plantations with limited biodiversity to provide feedstock for huge factories. Vital food-growing land would be lost to vast corporations farming wood for turning into biochar. It is a re-run of the biofuels disaster, he said.

The existing Kingsnorth power station. Image source: E.ON.
E.ON’s £1bn plan for a new coal-fired power station at Kingsnorth is waiting for approval from the UK government. Other generators have shifted away from coal. Drax, which owns by far the largest coal power station in the UK, is investing in biomass. Other companies have focused on new gas plants. Why is the world’s largest investor-owned utility pushing ahead with a project to burn coal without carbon capture?
The answer, unsurprisingly, is that burning coal to generate electricity is extremely profitable. Very low prices for emissions permits and tumbling coal costs mean that a profit-seeking management team is highly incentivised to try to push for permission to use coal in power stations. This article provides the background calculations for an estimate that the new Kingsnorth will generate an operating profit of about £300m a year if current fuel and carbon prices persist. Additionally, it also tries to show that the cost of fitting CCS equipment and running the plant to capture the large majority of all carbon emissions is likely to add no more than about 1.5p per kilowatt hour to the cost of generating electricity at current coal and carbon prices. This means that a new coal fired power station with CCS may have operating costs only marginally above gas power plants
Nevertheless, E.ON has just asked for government subsidy to install CCS at Kingsnorth from day one. The purpose of this article is to offer an estimate of the maximum the government ought to offer E.ON in order to get it to invest in CCS prior to opening the new power station.

The Maldives. Image source: Primetravels.com.
The Maldives will be the first country to be overwhelmed by the effect of climate change. The republic is a collection of coral atolls with maximum heights of one or two metres above sea level. Climate change is increasing worldwide sea levels and the atolls will probably go underwater by the end of the century.
The 300,000-400,000 people who live on the Maldives are not responsible for global warming. Their emissions per head (even including aviation fuels for incoming international tourism) are less than a seventh of typical European levels.
Many countries have set ambitious targets for the reduction of carbon emissions. The government of the Maldives seeks to encourage this trend by going one step further with a plan for near carbon neutrality within ten years.
This is an immensely challenging target. Chris Goodall (author of this blog) and Mark Lynas, the prize-winning climate change author, were asked to provide a short outline of how it might be achieved and what it might cost.[1]
In the rest of this note, we show our calculations. We will be the first to acknowledge that this work is incomplete. Although it was tempting to conduct fieldwork in some of the most attractive island resorts, we did our analysis using publicly available information and with help from officials attached to the Maldives government.
Our work shows that near neutrality is possible, but expensive. It will take at least $1.1bn for this small island state. The Maldives imports almost all its fuels in the form of refined oil products. Rates of financial return to the investment therefore depend largely on the price of oil. If expectations of future oil prices exceed $100 a barrel, we judge that the plan is sufficiently attractive to be financeable by international institutions such as the World Bank.
Comments on this work will be very gratefully received.
