Select Committee on Environmental Audit Written Evidence


Memorandum submitted by General Motors UK and Ireland

  This submission represents the views of General Motors, incorporating the Vauxhall, Saab, Chevrolet, Cadillac, Corvette and Hummer brands in the UK.

  We have provided responses to the majority of questions; some we have not responded to as we feel these are less relevant to the company and are more orientated towards the fuel supply industry.

INTRODUCTION:  GENERAL MOTORS' ADVANCED PROPULSION AND ALTERNATIVE FUELS STRATEGY

  General Motors has a comprehensive strategy aimed at removing the automobile from the energy and environmental equation, encompassing short, medium, and long-term goals.


  In the short term, General Motors continues to work on delivering further refinements to the conventional internal combustion engine, incorporating engine downsizing and turbo-charging, as well as active fuel management, six speed transmissions, and variable valve timing.

  As a specific example of these efforts, the 2007 mid-cycle Astra (GM's largest volume model in the UK), the five-door variant of which is manufactured at the company's Ellesmere Port assembly plant, delivers a 14% reduction in CO2 emissions across the engine range compared to the previous version of the vehicle.

Short to medium term, we are developing vehicles which can run on biofuels in both low and high blends, as a consumer-friendly and cost-effective way of reducing CO2 from the cars we sell.

  In the medium term, General Motors sees an important role for plug-in battery powered electric vehicles in delivering low carbon road transport. GM's E-Flex system is showcased in the Chevrolet Volt concept vehicle, launched at the Detroit Motor Show in January 2007, and the Opel Flextreme concept, launched at the Frankfurt Motor Show in September 2007. These prototype vehicles are battery powered electric vehicles which use a small turbo-charged internal combustion engine to produce additional electricity from petrol, diesel, ethanol, or biodiesel. The battery can be fully charged via mains electricity in six hours, providing 40 miles of pure electric range.

  With additional improvements to today's lithium-ion battery technology, GM anticipates that these vehicles could be ready for commercial production between 2010 and 2012. In June, GM announced it would be awarding contracts to two companies for advanced development of lithium-ion batteries—namely, Compact Power Inc., based in Troy, Michigan (a subsidiary of Korean battery manufacturer LG Chem), and Continental Automotive Systems, based in Frankfurt, Germany (a division of tier one automotive supplier, Continental A.G.).

  General Motors' long-term strategy is to develop hydrogen fuel cell vehicles which emit only water vapour at the tailpipe. The company has already invested in excess of $1 billion in research and development into hydrogen fuel cell technology. In 2005, the company produced the Chevrolet Sequel, the first vehicle in the world to travel 300 miles non-stop with zero tailpipe emissions.

  Next year, the company will launch the world's largest ever market trial of fuel cell vehicles, placing over 100 vehicles in the hands of customers, to give them first-hand experience of running a fuel cell vehicle in a real world environment.

  For fuel cells to become a viable mass market solution, we need to have in place a fuel cell propulsion system which can compete with conventional engine technology on cost, performance, and durability. In this context, the company continues to work hard to meet its stated corporate objective of designing and validating an automotive-competitive fuel cell propulsion system by 2010. We have recently announced a move to integrate our global fuel cell development team into the company's core powertrain and vehicle engineering functions, as the first step towards preparing this technology for future production.

  GM's latest, fifth generation of fuel cell propulsion system was introduced at this year's Shanghai Auto Show as the fuel-cell powered E-Flex platform used on the Chevrolet Volt.

1.  What are the possible positive and negative social, environmental and economic consequences of biofuels? How might trade-offs between climate benefits and environmental and social impacts be made? Is there a need to develop a new biofuel strategy for the UK or EU, to balance the environmental, social, economic and climate impacts of biofuels?

  There are undoubtedly some potential negative impacts associated with biofuel production, if this is carried out in an irresponsible or inefficient way.

  On the positive side, when responsibly and efficiently produced, biofuels can deliver significant source to wheels reductions in CO2, offering a cost-effective and consumer friendly means of reducing CO2 from road transport, as part of a broader environmental technology strategy.

  Fundamentally, GM believes that continued reliance on fossil fuels for 97% of global road transport needs is unsustainable. We therefore maintain that the UK and EU must adjust existing policy frameworks towards a broader strategy that encompasses the promotion of greater energy diversity and reduced reliance on fossil fuels. In this context we are convinced that promotion of biomass based fuels has a critical role to play.

2.  Should biofuels be regulated to minimise the negative environmental and social impacts, and in what way? How might regulation fit in with international trade agreements and rules? Should there be regulation of the entire carbon cycle of biofuels?

  Clearly, there is a need to develop mechanisms to ensure that carbon savings from biofuels are accurately measured, in order to encourage efficient production methods. GM believes that such mechanisms could provide a basis to incentivise low CO2 biofuels through specific taxation measures. GM is an active partner in the Low Carbon Vehicle Partnership (LowCVP) and supports its ongoing work to develop a robust system of carbon accreditation and sustainability certification in association with the implementation of the DfT's Renewable Transport Fuels Obligation (RTFO).

  At the same time, with specific reference to sustainability, GM is concerned that the specific impact of biofuels on broader issues of sustainability needs to be kept firmly in context. Increased demand for biofuels is only one factor affecting complex issues such as rising food commodity prices and deforestation in sensitive regions. Consequently, these issues cannot be expected to be resolved by a restrictive policy specifically focused on biofuels. At the same time, the risk associated with introducing premature and restrictive regulations on biofuel production is that these threaten to halt early development of an industry which, as already indicated, has a critical role to play in delivering greater energy diversity for the long term.

  Accurate measurement of the carbon impact of individual biofuels, tax measures to encourage efficient production and maximum carbon savings, and auditing and reporting fuel supply chains against defined sustainability criteria all have a role to play in ensuring that the emerging biofuels industry develops in a responsible and sustainable way, and delivers genuine and significant savings in CO2.

3.  How successful are existing international structures, such as the Roundtable on Sustainable Palm Oil, at ensuring that imports of biofuels can be obtained from sustainable sources? To what extent is it currently possible to identify the provenance and production standards of imported biofuels?

  GM believes that existing systems for environmental auditing could be adapted to measure the sustainability of biofuels throughout their supply chain.

4.  At what stage is biofuel technology? Is there enough support for the development of biofuel technology? A UN report found that the climate change benefits of solid biomass fuels outweigh those of liquid biofuels. Are current policies promoting the development and deployment of a range of biofuel technologies? How successful have EU strategies and Directives been in stimulating biofuel usage? Will the 2010 biofuel target be reached? How effective are the Government's fiscal arrangements for biofuels?

  The various biomass feedstocks used for producing biofuels can be grouped into two basic categories. The first is the currently available "first-generation" feedstock, which comprises various grain and vegetable crops. These are harvested for their sugar, starch or oil content and can be converted into liquid fuels using conventional technology. The yields from the feedstock vary considerably, with sugar cane and palm oil currently producing the most litres of fuel per hectare[14].

  By contrast, the "second-generation" of biofuel feedstock comprises cellulose-rich organic material, which is harvested for its total biomass. These fibres can be converted into liquid biofuels only by advanced technical processes, many of which are still under development.

  Second-generation biofuels offer several advantages over first-generation fuels, most importantly that they can be produced from agricultural waste by-products, thereby significantly increasing land use efficiencies.

  At present the cost of producing second-generation biofuels is very high. We are aware of a small number of government and industry-sponsored efforts to lower these costs, with some success. For example, there are at least two projects currently underway to produce ethanol from wood—a demonstration facility in Ottawa, Canada and a commercial-scale facility in Louisiana, USA[15]. Some development of "synthetic" biofuels is underway in Germany, Sweden and Austria[16].

  By providing additional incentives to encourage the domestic biofuels industry to develop and greater support for research into the development of second generation cellulosic biofuels from agricultural and forestry by-products, GM believes that the government can help to enhance the sustainability of biofuels for the longer term.

  While the UN may have produced evidence to suggest that the climate change benefits of solid biomass fuels outweigh those of liquid biofuels, GM would again point out the priority need to address the high level of dependence of road transport on fossil fuels, due to the current lack of widely available alternative energy sources for this sector. While the industry will continue to improve vehicle efficiency, increasing global demand for vehicles—particularly in developing countries—means that, in the long term, these efforts will not be enough by themselves to achieve significant reductions in CO2 output from road transport at the global level. Future ultra low CO2 alternative propulsion systems such as plug-in electric vehicles and hydrogen fuel cells (in which GM is investing heavily) will require a broad portfolio of renewable energy sources to generate power.

  By supporting the liquid biofuel industry now, governments will be supporting technologies which can be converted to solid biomass fuels at a later stage, as alternative forms of propulsion become more widely available.

  Concerning the effectiveness of the Government's current fiscal arrangements for biofuels, we maintain that these are currently entirely inadequate and can be summarised as follows:

    —  From April 2008, drivers of E85-capable cars will receive a 2% discount from annual company car tax.

    —  E85 vehicles qualify for a £20 discount from VED.

    —  The current rebate of 20 pence per litre on biofuels is fixed until 2010.

  By comparison, in Sweden, a wide range of consumer incentives is available, helping to equalise the cost of running a vehicle on bioethanol E85 as opposed to conventional fuel, specifically:

    —  A 20% discount from company car tax.

    —  A 30% discount from vehicle registration tax.

    —  Exemption from the Stockholm congestion charge.

    —  A 30 pence per litre rebate on fuel duty.

    —  Free city parking.

    —  A recently introduced government grant of 10,000 SEK (around £730) towards the purchase of an "environmentally friendly car" for private customers.

  In addition, there is a legal requirement in Sweden for 50% of all refuelling stations in the country to be equipped with a renewable fuel pump by 2009.

5.  The EU Strategy for Biofuels claims that biofuels "are a direct substitute for fossil fuels in transport and can readily be integrated into fuel supply systems". What proportion of UK domestic transport and energy generation could be fuelled by UK-produced biofuels? Is it possible for biofuels to entirely replace oil for transport purposes? Is there a role for public procurement or public transport? Will biofuels improve fuel security? How secure are biofuel crops from unexpected events such as drought or disease?

  Increasing energy diversity will undoubtedly help to reinforce security of energy supply. Increased use of biofuels can make an important contribution to this objective. At the same time, for GM, biofuels are just one element of a much broader strategy to reduce the environmental impact of our products. This strategy also incorporates continuing refinements to the internal combustion engine, use of hybrids, investments in plug-in electric vehicles and hydrogen fuel cells. We are also currently running a marketing campaign through our Vauxhall brand in the UK to encourage customers to trade in old vehicles for scrappage and recycling in exchange for a trade-in deal on a new, fuel-efficient Vauxhall.

  In accordance with the existing European fuel standards EN 228 for petrol and EN 590 for diesel, conventional GM vehicles in Europe are currently warrantied to run on a blend of no more than 5% bioethanol to petrol and no more than 5% biodiesel to diesel. Blending above 5% creates challenges for existing powertrains, although GM has made a commitment that, if European fuel standards are revised accordingly, we will make the necessary technical adjustments to allow blending up to 10% with conventional fuels. However, given the time it will take for the existing vehicle parc to be renewed, moving to a 10% blend as the standard for conventional fuels will create significant problems for many consumers for a significant number of years to come.

  On this basis, GM is firmly of the view that an effective strategy for the promotion of biofuels in the UK and across Europe needs to incorporate specific measures to encourage the purchase and use of vehicles equipped to run on high blend biofuels, alongside measures to encourage low level blending into mainstream fuels.

  Using figures supplied by the former DTI, DEFRA, and the National Farmers Union, General Motors has calculated that, over five years, there is enough spare arable land in the UK to produce sufficient bioethanol from wheat to achieve 5% blending with all petrol supplied in the UK and to power 22% of new car sales on E85 from domestic sources.

  As we move to second generation biofuels, which use waste by-products from agricultural production rather than the main crop, over five years, enough bioethanol could be produced from 50% of waste straw from UK cereal production to achieve 10% blending with all petrol supplied in the UK and to power an additional 10% of new car sales on E85 from domestic sources.

6.  What impact would an expansion of UK production of biofuels have on the ability of the UK to produce its own food? How might this impact on greenhouse gas emissions from international trade patterns? What impact might the expansion of biofuels have on international food security and prices?

  Please see the answer to question 5. We believe there is scope significantly to expand biofuel production in the UK without impacting on food production.

7.  How might farm viability in both developed and developing countries change with an expansion of biofuels? What implications are there for poverty in developing countries? Should we be concerned about large monopolies forming in the biofuel sector?

  As a vehicle manufacturer, GM does not feel qualified to answer this question.
