Select Committee on Environmental Audit Written Evidence


Memorandum submitted by the Woodland Trust

  1.  The Woodland Trust welcomes the opportunity to respond to this inquiry. The Trust is the UK's leading woodland conservation charity. We have four main aims: no further loss of ancient woodland, restoring and improving woodland biodiversity, increasing new native woodland and increasing people's understanding and enjoyment of woodland. We own over 1,000 sites across the UK, covering around 20,000 hectares (50,000 acres) and we have 300,000 members and supporters.

EXECUTIVE SUMMARY

    —  The biofuels industry is expanding rapidly. The Woodland Trust is concerned that policy, particularly with respect to environmental impacts, is not keeping pace with this development.

    —  Within the UK, where land is already subject to a number of conflicting pressures, there is a danger that expansion in biofuel crops to meet existing and future targets could compete with land-use for food production, recreation and nature conservation. The Trust is particularly concerned that important wildlife areas could be lost or managed inappropriately and there could be further intensification across the whole landscape.

    —  Developing technologies for production of "second-generation" biofuels offer more postive opportunities, since they could utilise woody material rather than traditional arable crops. This could create a market for low-grade timber, stimulating restoration of semi-natural habitats planted with conifers (including ancient woodland), and planting of new woodland and trees that could help to buffer and expand semi-natural habitats. Production of second-generation biofuels is also potentially more carbon efficient than production of fuels like bio-ethanol from conventional crops.

    —  Production of biofuels must be subject to minimum standards and certification, to ensure that it occurs sustainably ie creating genuine greenhouse gas savings, without negative environmental impacts, and where possible, providing positive environmental benefits.

    —  A more strategic approach is needed, including an assessment of the role of biofuels and other bioenergy in the UK's total energy mix, taking account of environmental constraints and the capacity of other renewables.

    —  Last, but most importantly, development of biofuels should take place within an over-arching strategy that recognises the need to reduce consumption and implement energy-saving measures.

2.  SUMMARY OF THE WOODLAND TRUST'S VIEW ON BIOFUELS

  2.1  The Woodland Trust believes climate change is the single biggest threat to biodiversity, including woodland biodiversity. Urgent measures are needed to mitigate the effects of climate change, reducing greenhouse gas emissions by curbing energy consumption, increasing energy efficiency, and the use of renewable sources that provide real carbon savings.

  2.2  The bioenergy industry, including production of biofuels, is growing rapidly. As well as potentially contributing to reducing greenhouse gases, bioenergy offers some positive opportunities to enhance biodiversity, could contribute towards measures to help adaptation of wildlife to climate change, and may also offer wider environmental benefits, for example, through provision of "ecosystem services" such as flood prevention. However, there is also a risk that, if not subject to the correct controls, the development of bioenergy could have a negative effect on biodiversity and the environment.

  2.3  The Woodland Trust supports the development of bioenergy, including biofuels, where it offers genuine greenhouse gas savings, where it does not negatively impact on biodiversity, and, if possible, it delivers positive biodiversity benefits.

3.  ANSWERS TO SPECIFIC QUESTIONS

3.1  Question 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?

  3.1.1  Globally, there is increasing concern about the effects of the expanding biofuels industry, particularly felling of tropical rainforest, displacement of poor farmers, and replacement of food crops with plantations of soya, sugar cane and other crops for biofuel production. While the Woodland Trust recognises that these issues are a major concern, our comments in this response will be largely confined to the potential effects in the UK, particularly the environmental impacts of biofuels.

  3.1.2  Earlier this year, Wildlife and Countryside Link, a coalition of environmental non-governmental organisations (NGOs), including the Woodland Trust, launched "Bioenergy in the UK: Turning green promises into environmental reality," a policy paper that set out six priorities for Government action to ensure that growth in UK bioenergy production would maximise greenhouse gas savings and minimise damaging environmental impacts. Many of the issues raised in this consultation response are dealt with in more detail in the policy paper, and we would recommend that the Environmental Audit Committee refer to it. A copy is attached.

  3.1.3  Bioenergy crops currently account for only a small percentage of land use in the UK but this is likely to increase rapidly over the next couple of decades to help meet national targets on use of bioenergy. For example, to meet the 5% by 2010 target on biofuels would require between 1.2m and 1.9m ha of additional wheat and oilseed rape1. At the same time, there is also pressure to increase the area of energy crops to provide heat and power; to meet just one-third of the government's 2010 target for electricity from renewables would require 1.2m ha of short rotation coppice (SRC) and Miscanthus (elephant grass)2. This is equivalent to about 20% of the UK's arable land.

  3.1.4  The specific environmental effects of particular biofuel crops depends on a number of factors:

    —  The type of crop.

    —  The land use it displaces.

    —  The management techniques employed in growing and harvesting.

    —  The scale and location of bioenergy development.

  3.1.5  Currently, most developments in biofuels in the UK require the use of traditional agricultural crops such as sugar beet, wheat or oilseed rape. However, in the future, emerging technologies will enable the use of more woody feedstocks: timber from existing woods, short rotation coppice and forestry, and energy grasses such as Miscanthus to produce "second-generation biofuels." Research3 indicates that such fuels are more efficient in delivering greenhouse gas savings than those produced from traditional arable crops, and the estimated yield per hectare from second generation feedstock is much higher, since the whole crop can be used.

  3.1.6  Within the UK, such developments could offer some really positive opportunities for woodland and its wildlife. The stimulation of markets for wood products (low grade timber and forest residues, SRC and short rotation forestry (SRF) could lead to improvements in woodland biodiversity through:

    —  Restoration of Plantations on Ancient Woodland Sites (PAWS).

    —  Bringing woods into sensitive and appropriate management, where it can be demonstrated that this will have biodiversity and/or social benefits.

    —  Expansion of native woodland, and buffering of sensitive woodland eg ancient woods with low-intensity new planting, including SRC.

    —  Renewing public and political appreciation for the value of woodland to society.

  3.1.7  It could also lead to additional "ecosystem services" benefits—for instance, replacing traditional arable crops with SRC could lead to improved soil and water quality because if done correctly it requires lower inputs of fertilisers and pesticides. SRC and SRF can also absorb pollutants, and could therefore be used to buffer sensitive habitats such as ancient semi-natural woodland from the effects of nearby intensive land-use. SRC can also help to ameliorate major downstream flooding events in floodplains by reducing flow rates and planting tree species can help to reduce soil erosion. Even perennial grasses, or conventional arable crops planted for biofuels, might lead to reduced intensity of land-use, depending on where they are planted, the land-use they replace, and how they are managed, contributing to a landscape that is more permeable to wildlife enabling adaptation in the face of climate change.

  3.1.8  However, biofuel crops also pose some real threats. Planting of semi-natural or other valuable unprotected wildlife (UKBAP) sites with energy crops is a risk if demand for bioenergy continues to rise in the UK, and begins to compete with the other services we demand of our land; for example, land with semi-natural characteristics, such as permanent pasture, semi-improved grassland and wet grassland, could be at risk, and in particular, set-aside land that has been left fallow and has developed biodiversity value.

  3.1.9   Maximising greenhouse gas savings requires minimising the use of artificial nitrogen inputs, but unless producers are required to deliver higher greenhouse gas savings, a growing market for conventional agricultural crops for biofuels could cause intensification of production.

  3.1.10  The need to cluster crops near to processing plants in order to reduce transport emissions and costs could lead to large concentrations of monoculture, which would threaten both biodiversity and landscape character.

  3.1.11  The effects of non-native species that are currently relatively unknown in the UK (eg Miscanthus) have not been adequately researched, and the use of genetically modified organisms could pose a further threat to biodiversity.

  3.1.12  Current evidence is that the greatest potential greenhouse gas savings can be achieved through burning of woodchip to generate heat, gasification of biomass to produce electricity and the use of second generation biofuels produced from biomass4. The Woodland Trust would therefore like to see bioenergy policies place greater emphasis on the use of woody biomass crops for these purposes, rather than on agricultural crops such as sugar beet and wheat for the production of biofuels.

  3.1.13  There is a need for the growing, harvesting and processing of all biofuel crops to be subject to minimum standards and certification of greenhouse gas savings and environmental impacts. Greenhouse gas certification should be based on the work already conducted for the greenhouse gas reporting mechanism that will form part of the Renewable Transport Fuels Obligation (RTFO). For forestry crops, sustainability certification should be basedon existing independent standards: the UK Woodland Assurance Standard and the Forest Stewardship Council's certification scheme.

  3.1.14  There is a real need to assess the biodiversity, landscape, and wider environmental effects of the developing market for biofuels in the UK and develop a coordinated strategy for the future development of biofuels that takes these into account. The policy statement recently published by Wildlife and Countryside Link, of which the Trust is a member5 sets out a number of recommendations to Government for the sustainable development of bioenergy. This could inform a future strategy for biofuels and includes the following key points:

    —  Undertake a strategic assessment of the role of bioenergy in the UK's energy mix, seeking to identify the level and type of bioenergy production that should be encouraged, taking account of environmental constrains.

    —  Introduce minimum standards and certification of greenhouse gas savings and environmental impacts.

    —  Ensure the planning system is equipped to respond to the pressures on land use of bioenergy projects and provides appropriate policy and guidance.

    —  Identify the opportunities for bioenergy to contribute to the achievement of other environmental goals eg flood defence, improvement of biodiversity—and ensure these are acted upon.

    —  Actively promote small scale local uses of bioenergy.

    —  Undertake further research to ensure bioenergy policy is based on a thorough understanding of environmental threats and opportunities.

3.2  Question 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?

  3.2.1  Production of biofuels should be subject to minimum standards of greenhouse gas savings and environmental impacts. A certification system should be developed, linked to financial incentives and credits, as soon as possible, and that this must apply internationally, and should regulate the entire carbon cycle of biofuels. (see 3.1.13 above).

3.3  Question 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?

  3.3.1  The Woodland Trust supports the use of woody biomass for the production of heat, power, and second-generation biofuels, where such biomass is produced without negative environmental impacts, and, if possible, delivers positive biodiversity and wider environmental gains, as described above. However, there are many barriers to the use of such products for second generation biofuels, including the cost of harvesting in woods with poor access, lack of infrastructure required for mobilisation of the timber, and the cost of the processes required to produce second-generation biofuels. Investment is needed in development of infrastructure and markets, and further research into the production processes.

3.4  Question 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 unexpectedevents such as drought or disease?

  3.4.1  Given the many conflicting pressures on land use in the UK, it is unlikely that domestically produced biofuels alone will replace oil for transport purposes. The use of biofuels from the UK or overseas should only be promoted if it can be demonstrated that they are, truly, produced sustainably. However, we would also urge that over-arching all policies on bioenergy must be a recognition by Government and others of the need to reduce consumption through energy-saving measures, and to work towards "one-planet living".

3.5  Question 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?

  3.5.1  The expansion of biofuels is already impacting on world food prices, as demonstrated recently by rising prices of maize and wheat. Incentives for growing biofuel crops could lead to competition between use of land for food and fuel within the UK, as well as elsewhere in the world. This underlines the need for a coordinated strategy which assesses the available resource for production of biofuels, and other bioenergy, taking into account the many other pressures on land in the UK.
