    Throughout history,

    bioenergy has been

    important for satisfying

    human needs. At present,

    it is primarily used for

    heating and cooking in

    the developing world. But

    as world leaders

    contemplate the post-Kyoto framework, muchattention is being given to new, modern uses of

    bioenergy. Biomass substitution for fossil fuels in heat

    and power systems could play an important role in

    stabilizing our carbon emissions. As leaders begin to

    discuss carbon emission reductions of 50% by 2050,

    biofuels could take on an urgent role in emissions

    mitigation in the transport sector.

    In addition to climate change as a driver, increasing

    concerns about the rising cost of hydrocarbon-based

    transportation fuels and growing concern over energy

    security are causing many countries to view biofuels as

    a key element of national energy strategy. Although

    less efficient than when used for heat, power or

    manufactured forest products, biofuels may yet prove

    to be societys choice. In any event, biofuels are

    currently the alternative that is being actively

    promoted in many parts of the world.

    Overview

    Introduction

    Bioenergy Biofuels Biomass

    Bioenergy is energy produced from organic matter

    (biomass).

    Biofuels are liquid, solid or gas fuels derived from

    biomass, either from recently living organisms or from

    their metabolic waste. Biomass refers to organicmaterial made from plants and animals.1 The

    production of biomass and biofuels must be carried

    out sustainably in order to balance the carbon cycle

    and keep it intact, and to ensure that the

    environmental and social impacts of their production

    are acceptable.

    This issue brief focuses on the use of biofuels in the

    transport sector. Although biofuels are being pursued

    as a possible alternative to fossil fuels, currently most

    of the biofuels available for motor fuels are more

    expensive to produce per unit of energy delivered

    compared to oil derived from fossil fuels. If fuel costs

    are to come down, considerable development and

    Overview

    government investment will be required to improve

    manufacturing and distribution technology.

    Biofuels include a number of different products and

    manufacturing pathways (see Figure 1). The most

    widely used biofuel, ethanol, is currently made

    largely from sugar cane in Brazil and from corn in the

    United States. Meanwhile, the largest producer of

    biodiesel is Germany, where the fuel is made fromrapeseed. Each pathway, from the resource to the

    conversion technology to the fuel, has its own

    distinct carbon footprint.2

    Our principal source of data for 2005, as well as for

    2030 references, has been the International Energy

    Agencys (IEA) World Energy Outlook (IEA, 2006).

    Projections to 2030 are based on the IEA Alternative

    Policy Scenario (APS); 2030 is the year that has been

    chosen to project the cumulative impact of the

    implementation of the national policies under

    consideration in 2005. Currently, a number of key

    countries are contemplating more aggressive targets

    for the production of biofuels. The IEA is examining

    much more forceful policy scenarios for discussion

    during the post-Kyoto framework negotiations.

    Global production of biofuels reached 20 million

    tons of oil equivalent (Mtoe) in 2005, representingabout 1% of total road-transport fuel energy

    consumption. Brazil and the United States together

    accounted for almost 80% of global supply (see

    Figure 2). Ethanol production is rising rapidly in

    many parts of the world in response to higher oil

    prices, and supported by government incentives and

    rules on fuel blending. Similarly, biodiesel

    production is highly concentrated, with the

    European Union responsible for around 75% of total

    biodiesel production (see Figure 3).

    Overview

    First generation

    biofuels refers to fuel

    derived from feedstocks

    harvested for their sugar,

    starch and oil content,

    which can be converted

    using hydrolysis/

    fermentation and

    Firstgeneration

    Second generation

    biofuels describe those

    produced from ligno-

    cellulosic biomass, such as

    herbaceous and woody

    perennials, through

    hydrolysis/fermentation,

    gasification or pyrolysis

    technologies. There is no industrial production ofbiofuels from cellulosic biomass, but research

    focusing on large-scale production is being carried

    out particularly in the United States, Canada,

    Germany, Sweden, China and Brazil.

    Successful ligno-cellulosic technology would

    technically allow the utilization of a large variety of

    feedstocks, as well as agricultural or municipal waste

    materials and specialized cellulosic crops, such as

    grasses and fast-growing trees.

    Cellulosic feedstock could be grown with less

    fertilizer and water and on poorer quality lands than

    those currently used to grow crops for conventional

    ethanol production. Furthermore, cellulosic crop

    costs could be considerably lower when compared to

    those of the cereal and seed crops currently used in

    Europe and the United States.

    Figure 4 illustrates current biofuel production costs,which are projected to drop with upgraded

    technology and conversion processes and improved

    economies of scale. Aggressive energy policies and

    anticipated revenue from carbon markets are driving

    investment in biofuels. Experience will lead to lower

    production costs. Over the next few decades, ethanol

    is expected to account for the greatest proportion of

    the increase in biofuel use worldwide, as production

    costs are predicted to fall faster than those of

    biodiesel and other biofuels.

    pressing/esterification technologies. In OECD

    countries, most ethanol is produced from starchy

    crops such as corn, wheat and barley. In tropical

    countries like Brazil, ethanol is made primarily from

    sugar cane.

    According to the IEA, fuel

    demand from the road

    transport sector is forecast

    to increase considerably

    over the next few decades,

    especially in developing

    regions. Biofuels are

    projected to account for a

    growing share of the resources used to meet thisdemand. Production is expected to increase at a rate

    of 8.3% per year, reaching 73 Mtoe in 2015 and 147

    Mtoe in 2030, to meet 7% of global road-transport

    fuel demand (see Figure 5).3

    Previously, it was believed that second generation

    biofuel technologies would not be available on the

    market by 2030; however, government funding

    could change this. Advances in the development of

    these technologies will be necessary before they can

    be deployed commercially on a large scale. It is

    possible that such breakthroughs could occur in the

    near future leading to more rapid development of

    biofuel production than previously expected.

    The single largest cause

    of ecosystem degradation

    is land use change for

    agriculture, which is

    driving conversion of

    grasslands and forests.

    The present share of the

    worlds arable land used

    to grow biomass for biofuels is expected to rise from1% to 3.8% by 2030, based on the assumption that

    biofuels are derived solely from conventional crops.

    The issues

    Landrequirementsand land use

    change

    If second-generation technologies based on ligno-

    cellulosic biomass were widely commercialized

    before 2030, arable land requirements could be

    much less per unit of biofuel output since an

    important fraction of the biomass needed could

    come from regenerated and marginal land not

    currently used for crops or pasture, as well as from

    agricultural and forest residues and waste.

    Food security is one of the

    major concerns

    surrounding the

    sustainability of the

    biofuel industry. Biomass

    production competes withfood, fiber and timber for

    land, water and fertilizers.

    There is a fear that this competition could lead to

    commodity shortages, as crops that would otherwise

    be available for food or forest products might be

    used for fuel. According to one estimate, agricultural

    and livestock prices could rise from 20% to 50% by

    2016 as a result.5

    Moreover, biofuel production negatively affects the

    exports of certain crops; for example, recent exports

    of US corn and soybean, Western European rapeseed

    and Brazilian sugarcane have declined. Rich, crop

    importing nations with greater purchasing power

    could demand these crops at higher prices, thereby

    further increasing their prices. For the poor, who are

    net buyers of food, this would place even greater

    pressure on already-limited financial resources.

    However, such increases in the demand for, and price

    of, crops can provide higher returns to farmers.

    Moreover, higher prices for agricultural crops are onepossible answer to the paradox of agriculture.

    Under this paradox, during periods of high yield,

    farmers have had to sell their output at low prices

    because supply outstripped demand. Now that there

    are potentially alternative uses for food crops, supply

    and demand could become more balanced, resulting

    in higher prices for agricultural produce.

    One of the outcomes of this paradox is that farm

    income subsidies have been used broadly by

    Competitionfor food, fiber

    and forestproducts

    many governments to sustain farming as a viable

    business sector.

    Biofuels, as a new value-added use of agricultural

    products, creates the potential for many more farmers

    to improve their businesses and reduce or eliminatethe need for ongoing income subsidies. Similarly,

    higher demand for biomass could reduce the amount

    of food dumped internationally.

    Finally, the problem of food scarcity in certain areas is

    currently more an outcome of inequitable distribution

    due to the existing food distribution system, an issue

    which is outside the biofuels domain.

    Integrating agricultural

    markets of countries where

    there is potential for

    providing feedstock at low

    cost with fuel demands of

    the high-consuming

    countries will speed the

    deployment of biofuel

    technology. Rapid deployment will present

    environmental and social sustainability challenges.

    Creating and implementing a certification system based

    on sustainability criteria could play an important role in

    addressing these challenges and ensuring that biofuels

    are produced in a responsible manner.

    Different biofuel production technologies have very

    different carbon footprints. For instance, cultivation ofenergy crops on depleted agricultural soils can yield

    beneficial carbon sequestration effects in addition to

    providing habitat and other ecosystem services. But

    those same practices on undisturbed peatlands would

    have negative impacts on water and habitats. They

    could result in a large, one-time release of carbon from

    the soil that overwhelms the positive benefit of the

    displaced fossil fuel consumption.

    The issues

    Sustainableproduction

    Thus, criteria that are quantifiable, and yet flexible

    for application in various settings, could focus on

    areas such as GHG emissions, crop production,

    biodiversity protection, food security and labor

    conditions, among others. Moreover, it would be

    imperative that compliance with established

    criteria be enforced and for such enforcement

    to not be costly.

    The strain the worlds liquid fuel demand will place

    on tenure systems and the lives of the rural poor will

    be difficult to manage, yet by developing a system

    that represents diverse stakeholders, such strain could

    be alleviated. Several groups, such as the Roundtable

    on Sustainable Biofuels, are exploring robust

    certification systems that can distinguish the nuances

    of environmental and social sustainability. Such asystem would have to be deployed globally to enable

    end users to discriminate among fuels that respect

    sustainability criteria. Finally, harmonization of

    standards across countries could help various

    stakeholders, particularly vehicle manufactures, to

    develop uniform technologies, which could be fairly

    easy to disseminate.

    Given that more than

    three-quarters of poor

    people in developing

    countries live in rural

    areas, agriculture and

    rural development are

    critical to poverty

    alleviation.7 Biofuel

    production has a huge potential to reduce poverty bycreating income and wealth generating activities

    while also meeting local energy demands. With these

    potential opportunities, however, come issues of land

    ownership, labor rights and food security, among

    others. Biofuel programs, for instance, can be

    especially harmful to farmers who do not own their

    land. Moreover, unsafe working conditions and

    abuse of labor rights threaten economic and social

    progress. Therefore, making the right decisions now

    and creating appropriate policies is a key component

    to ensuring poverty alleviation and an equitable

    distribution of growth.

    Ruraldevelopment

    As the second generation technologies based on ligno-

    cellulosic feedstock become commercially viable, this

    will reduce the potentially negative effects on land and

    competition for food availability. But these technologies

    could still be accompanied by a risk: a potential

    increased likelihood of a greater push to exploit low-

    yield lands (such as rangelands and savannas) to plant

    switchgrass and other hardy biofuels, and the

    displacement of cereals and subsistence crops.

    Furthermore, the production of significant quantities of

    biofuel feedstock on marginal lands could compete

    with livestock grazing, have unacceptable impacts on

    ecosystems, and damage soil fertility through

    sustained removal of too much biomass residue. One

    potential alternative feedstock under active

    development is micro-algae. Although such

    production raises the issue of genetic engineering,

    algae could help avoid a number of the sustainability

    issues associated with land use, freshwater use,

    deforestation and food production.
