The bioethics of bioenergy
Toimittanut Ulrica Gabrielsson
The bioethics of bioenergy November 17, 2009 The seminar is organized by the Nordic Committee on Bioethics (www.ncbio.org) and the Association of Parliament Members and Scientists (TUTKAS). During recent years the interest in developing alternative sources for renewable energy has increased dramatically. The up-coming climate conference to be held this fall in Copenhagen will focus on international restrictions on green house gas emissions. Different sources of bioenergy have been suggested and renewable energy is now being promoted as an alternative to fossil fuels. The large-scale production and consumption of bioenergy raises, however, a host of ethical issues. This one day seminar will present different dimensions related to the production and use of different types of bio-energy, the impact they may have on the environment and consumer choices, as well as the direction and possibili-ties that ongoing research is offering to development. In this seminar will include a number of international experts who will present on topics ranging from the latest technologies available for the production of bioenergy to ethical aspects. With the seminar we hope to provide a meeting place for experts, citizens and political representatives to discuss these issues in a constructive environment.

BIOETHICS OF BIOENERGY 17 November 2009 Chair Susanna Huovinen Eduskunta Environment Committee Dear audience, It is my pleasure to bring the greetings of the Eduskunta Environment Committee to this seminar, which is focusing on an important and topical subject. The Environment Committee views bioenergy as one of the central means with which to curb climate change, but we also recognise the need to improve awareness of the diverse impacts energy use has. The Committee has considered these matters in many of its submissions. Our submission regarding the national climate strategy, for example, dealt with several aspects of this subject. First and foremost I must, in relation to bioenergy – as in the case of all other energy forms as well – stress the great importance of the Copenhagen Climate Conference. Climate change is a global threat that calls for a global solution, and the role of bioenergy as a substitute to fossil fuels must be examined as a part of this. Research in climate science is progressing so rapidly that it has proven very challenging to secure the most recent knowledge to serve as a foundation for political decision making. Since climate change poses such a great challenge to humankind, we need to develop our ability to compile scientific research findings into a form, which facilitates decision making, much faster than at present. The challenge for the Intergovernmental Panel on Climate Change (IPCC) is substantial, as it has to combine the findings of researchers from countries all over the world. December’s meeting in Copenhagen needs to achieve a comprehensive and sufficiently ambitious agreement on reducing greenhouse gas emissions. An opening speech I heard at a recent event made me sit up and think. The speaker said that he was sick and tired of hearing talk about saving the planet because he reckoned that the planet would save itself – just as it had always done up to now. His view was rather that humanity should take action to save itself. The treaty that will hopefully emerge from the Copenhagen conference should therefore secure the commitment of all countries and present its objectives in a sufficiently clear form. If we fail to achieve this primary objective, details on, for example, carbon sinks will not, in my view, play as significant a role as they would if a comprehensive treaty were in force. Ladies and Gentlemen, The effort to replace fossil fuels that is being led by industrialised countries must not be allowed to speed up the destruction of tropical forests. As we know, many of the indirect effects associated with land-use issues are already very difficult from the point of view of deforestation. A fifth of all greenhouse gas emissions on the global level is caused by tropical forest destruction. This is why forest-related questions must be incorporated into the global treaty. Forests and issues related to forest carbon sinks are essential for Finland. It is a good idea to emphasise the crucial significance of scientific knowledge in responding to the challenge of climate change. Appropriate decisions cannot be made without a scientific understanding of, for example, how carbon sinks function. I would like to also point out that the challenge of global consideration does not apply to forests alone. We have to find a way to reduce our own emissions in a way that does not lead to increased emissions or hamper sustainable development elsewhere in the world.
So let’s hope that a global treaty is achieved – my personal view is that the EU’s common reduction target could be as high as 30%. We know, however, that this all just a prelude: emissions need to be reduced by as much as 80% by 2050. It would be best if we began adjusting to the new situation at once. This applies also to the climate funding that developing countries are calling for. To win the support of developing nations for a comprehensive treaty, the EU needs to commit to a sufficiently large amount of climate funding. We inhabitants of the prosperous northern hemisphere cannot expect the developing countries to do their share without our support. Active engagement with this common undertaking would be in our own best interests as well. We can still prevent climate change from breaking away from the two-degree target if we work together. Dear audience, The Environment Committee has emphasised that, for Finland, the strategic objective should be set at halting and reversing growth in energy consumption. In addition to this, we need to substantially improve our energy-efficiency as well as adopt a vision of an emission-free energy economy. It would also be good if we considered how Finns could take advantage of the ongoing energy transition. The search for emission-cutting solutions is now on all over the world, and it is imperative that we do not fall by the wayside of this trend. A competitive advantage on the international markets cannot be established without bold and concrete national objectives that produce demand within the domestic market and thus create a reference for the broader markets. Any increase to renewable energy utilisation has to take into consideration the principles of sustainable development. We must select the environmentally, socially and economically most sustainable energy forms and know everything about the impact they have on the environment over their full lifecycle. We must not forget to evaluate their regional, social and health effects either. The effects of bioenergy utilisation on biodiversity should also be examined. Forest utilisation, for example, can, up to point, be made more effective. Models, which can identify and limit the harmful environmental impacts of forest energy use, need to be developed. We need scientific knowledge and evaluations as well as wide-ranging socio-political debate to support political decision making. I believe that knowledge, which will enable us to realise our common great challenge to climate change also on the practical level, is being shared and disseminated at this seminar, too. I hope that your meeting is fruitful and I thank you for your attention.

Indirect land use change (ILUC)
•The EU will provide a report on this issue by 2010 with steps to minimise impacts.
•No scientifically proven methodology exists yet.
• All indirect effects are difficult to measure ►
•Inclusion of an immature system could affect
competitiveness.
•The system needs to be announced well in
advance, especially if ILUC effects are
incorporated only for biofuels
•Such notice is important for investors and the
realisation of new projects.
•Existing production plants should be granted a transition window.
Statoils Sustainability principles
1. We aim to be familiar with the origin of our biofuels and emphasize traceability through the whole production chain.
2. Our biofuels shall contribute significantly to greenhouse gas reductions compared to fossil fuels in a life cycle
perspective.
3. We do not use feedstock from rain forests or other areas with high carbon stock.
4. We actively work to prevent damage to biodiversity, ecosystems and areas of high conservation value.
5. We emphasize protection of soil, water and air in all our activities.
6. We aim to prevent displacement of food production important for sustainable livelihoods.
7. We aim to contribute to positive local development through agricultural competence building and job creation.
8. We support the protection of labour rights and human rights in accordance with the UN Global Compact Initiative,
applicable ILO standards and the UN Declaration on Human rights. We follow relevant national legislation and work
against corruption in all its forms, including extortion and bribery.
9. We contribute to develop new technologies for sustainable biofuel production.
10. We expect our suppliers and partners to follow our sustainability requirements. We audit their sustainability performance
on a regular basis to ensure compliance and motivate improvements.
• We support the work of RSB*, which covers the EU requirements and more.
• The establishment of one internationally accepted certification system would be preferable.

New types of bioenergy – algae in energy production
microalgae as raw-material for biofuels
Kristian SpillingFinnish Environment Institute, SYKE
What is algae
Simple plants (e.g. without roots)Macro and micro formsVery diverse
Scrippsiella hangoei
Peridiniella catenata
Pauliella taeniata
Thalassiosira baltica
Chaetoceros wighamii
Baltic Sea species
20 µm
Micro-algae
Aquatic, free-floating, unicellular orfilamentous (phytoplankton)Can be very fast-growingHave minimal amounts of structuralcomponents
Why planktonic algae? – biology and biochemistry
Harvest cycle• Forest biomass: years to decades• Field biomass: months• Microalgae: days, even hours
Biomass composition• Oil compounds (lipids) can be very high (even 40-60%)
Production per area• Higher to very much higher (2-10 times), compared
with the best terrestrial crops
Additional benefits of algae
Do not compete for fertile landSalt or wastewater can be usedPotentially very positive energy / carbonbalanceCan be coupled with CO2 producing industry
www.freephoto.com
www.waterencyclopedia.com
Research history
Aquatic Species Program (ASP)• USA, 1978-1996• Focus on open algal cultivation systems for bio-
diesel
Research for Innovative Technology ofthe Earth program (RITE)• Japan, 1990-2000• Focus on closed photobioreactors, CO2 mitigation
and higher value products
After 2000, renewed focus
Renewed focus on microalgae
Political focus on biofuel• Climate change• Energy independence (high oil price)• Biofuel can be used with present infrastructure
Problems with traditional energy crop• Energy vs. food production• Biodiversity (e.g. cutting down rain forest)• Energy / carbon balance
Projected raw-material shortage(EU’s target is 10 % biofuels by 2020)
Why biofuels?
Climate change (CO2)• Biofuels offer a closed carbon loop (in theory)• Can be used now (with small modifications)
What about hydrogen or electric vehicles• No-emission-fuel is environmentally the best option
(NB! whole life cycle must be taken into account)• But it requires full change of infrastructure (takes time)
What are the alternatives• As price of crude oil ticks upwards several alternatives
becomes economical viable• Most are more polluting than fuels refined from crude oil,
e.g. fuel from coal or tar sand
Any bioethical concerns of algal biofuels?
Need for CO2 in higher concentrationthan in airDependence on fossil fuels?
A lot of CO2 also from other sourcesMore energy output per CO2 emitted

The mutual strength of the constraints governs the composition of the future energy systems
Land and biomass constraints- some key aspects and figures
How big are the new customers for biomass?Earth land area: 15 Gha; global agricultural area: 5 Gha– of which 1.5 Gha arable land and 3.5 Gha pastures
World average food intake: 2700 kcal/pers/day ≈ 25 EJ/yearAgricultural biomass today ≈ 100-150 EJ/yearFossil energy consumption today ≈ 400 EJ/yearBiomass for full fossil substitution today ≈ 500-600 EJ/year→ we need ≈ 5 times more biomass than today‟s agricultural output for full fossil substitution
Can agricultural yield increases reduce the gap?Yield increase in agriculture ≈ 1% per year → 0.8 %Consumption growth (GDP/capita) ≈ 3% per year → ?? %Land use increase from trend towards more meat on the menu
≈ ??% per year
Land and biomass constraints- some key aspects and figures
How much new land can be cultivated?
New cultivable land: Biophysical maximum ≈ 2 Gha more– most of which is in South America and Africa (Ramancutty et al., 2002).
BUT: cultivating new land can imply a 2-9 times higher release of CO2 than energy crops can save over 30 years by substitution of fossil fuels (Righelato and Spracklen, Science 2007) – meaning pay back of 60 – 300 years.
Sustainable new land cultivation30-40% more (Danish Ministry for Food and Agriculture, 2008)- and we need 500% more if biomass should fully substitute fossil fuels

On the short term: don‟t cross the river to fetch water:Do not convert biomass to transport fuels. Instead exchange biomass to transport fuels in heat and/or power sector
On the longer term: we run into the carbon ressource constraint:Recycle CO2, i.e. use biomass in stationary applications and produce transport fuels from the CO2
Social/ethical constraints- influencing food availability and prices?
Can the food sector be influenced?
Crop prices have almost doubled, to some extent catalysed by USA‟s production of bio-ethanol (USA‟s bio-ethanol being 30-70 % of the reason says World Bank report, USA says something else).

Conclusion
Use of biomass in stationary appliances is by far the most eco-efficient and cost-efficient solution on the short term. It is, moreover, a good platform for the long term development.
Making transport fuels from CO2 is a sustainable solution. But the conventional route by terrestrial plant photosynthesis is:
– Too slow – much too low carbon flow rate– Too inefficient– Too costly, and– Too land intensive and, thus, interfering with food production (with respect to 1G)
The present liquid biofuel technologies will, thus, take us no-where. And while doing that, they may create a lot of misery and offset the right development for an in-affordably long period of time.
The technologies for methane, methanol and other fuel productions from CO2and electricity/H2 can prove to be real sustainable solutions.

Ethical concerns of bioenergy use
Associate Professor Mickey Gjerris
Danish Centre for Bioethics and Risk Assessment
University of Copenhagen
Conferences on developments within technology and natural science often have designated talks to look into the ethical concerns related to the specific area of the meeting. There is thus more than a trend in contemporary applied ethics to split thinking into smaller and smaller areas of technology and natural science, thus becoming very good at finding the specific concerns within an area, but at the same time missing all the basic concerns since they apply across large areas of human action. Why are we doing this and what do we expect the outcome to be? The answers to those questions and a clarification of who “we” are can often enlighten the discussion.
This talk will thus focus on the ethical issues in bioenergy by taking a step back. When asked to analyze the ethical concerns of bioenergy use, the task is first and foremost to clarify what is meant by “ethics”, and “bioenergy”. As there will be many experts talking on the concept of “bioenergy” this talk will focus on the ethical part. This entails A: looking at the main areas of concern within the complex area of bioenergy and B: looking at some of the different ways of understanding ethics typically found within discussions like this. The hope is to show how a call for ethical thinking might complicate matters more than initially expected – and to show why this is not such a bad thing after all.

Overview
• An impossible task
• Ethics
• Ethical concerns related to bioenergy
• Let´s have a dialogueAn impossible taskp
• The task– ”Identify the ethical concerns related to bioenergyuse”
– ”Identify the economic potential in biotechnology”
– Too many• Known unknowns• Unknown knowns• Unknown unknowns
• Bioenergy (Wiki):– Bioenergy is renewable energy made available from materials derived from biomass
– Biomass is any organic material which has stored sunlight in the form of chemical energy
– Bioenergy can thus be extracted by a variety of methods from a variety of sources in a variety of forms for a variety of purposes
– As you will have heard many brilliant people describe different aspects of this, I will focus on Ethics
18‐11‐2009

• Ethics (wiki)– Meta‐ethics
• Semantic, ontological, and epistemic nature of ethics
– Normative ethics • How moral values should be determined
– Applied ethics• How a moral outcome can be achieved in specific situations
– Descriptive ethics• What moral values people actually abide by
• 3 options– Present endless list of concerns
– Select a specific kind of bioenergy and a specificethical theory and figure out the concernsethical theory and figure out the concerns
– Ask basic question about why and how we ask the question of ethics
Ethics
• We do not usually spend much time reflecting
on ethics, but rely on our norms
• Sometimes we are confronted with situations
where we are forced into thinking about
ethics
– The conflict between what we believe is right and
what we do
– Complex situations
Lars Von Trier: De fem benspænd (The Five Trippings), 2003

• Ethics is a phenomenon closely related to ourfeelings
• We are creatures that are impressable. The world can reach us through our feelings
• Our feelings of right and wrong is the basis of g g gethics
• Ethics is more than feelings– Individual ethical perspective
– Institutional attempts to frame the issues
– Critical reflection
• Ethics as a hammer– The ethicist as an expert: a philosophical plumber
– Discussing ethics solves problems and justifiesactions
– The purpose of ethics is often seen as providingp p p gthe tools to create a socially acceptable development
• Ethics as a flashlight– Knowledge about the issue at hand
– Understanding of our own perspective and partialunderstanding of the perspectives of others
– Facilitating a more transparent dialogue on the basis of this
• What is applied ethics?– Applying a pre‐cut band‐aid to new concerns
– Rethinking ethical values in the light of cultural and technological developmentand technological development
– Trying to grasp what new challenges arise within a certain area
– Placing the concerns within a given area within a larger context, describing how they are connected in time and space to other issues
• Claim:– More and more ethical research is tied up withspecific projects within natural science
– Natural science is becoming more and more specialized
– Upside• Ethics get into the details, points to new challengesg , p g(awareness creation), becomes relevant to scientistsand enables an informed discussion ‐When it works
– Flipside• Ethics get caught in the details, is unable to discusswhat is common, is reduced to a lubricant and onlyleaves room for ”ethically” cost‐benefit analysis – Whenit is worst

Ethical concerns related to bioenergy
• Questions that can be asked to all uses of bioenergy
– Will it help solve or increase• Climate problems (Global warming)• Environmental problems (Pollution)• Social problems (Hunger, Inequity)• Fuel problems (Fossil fuel dependence)
– Will it benefit or harm• Humans• Animals• Plants• Ecosystems ‐ Biodiversity
• For each use of bioenergy the answers willchange
• Add to that the scientific and economicuncertainty of the effectsuncertainty of the effects– The competition of guesstimates

What is most discussed
• The ethics of turning food into fuel
• Impact on food prices
• 1. generation vs. 2. generation vs. 3. igeneration
• CO2 emission impact
• Effects on agricultural sector and North‐South balance
18‐11‐2009
5
What is less discussed
• That the discussion of Fuel vs. Food takes place in a context of a cultural understanding of ”freedom” as equal to ”instant private mobility”
• The problem of ”hyped” science and the blind searchfor technological solutions across the board
• The possibility of creating local economies and leaving globalized trade behind
Let´s have a dialogueLet s have a dialogue
• Science‐oriented– Dialogue is information going out
• Belief in the knowledge deficit myth• Dialogue as monologue
• Policy‐oriented– Dialogue is information going in– Dialogue is information going in
• Belief in the value of votes• Dialogue as ”marketing” research
• Flash‐light‐oriented– Dialogue is value discussion
• Belief in certain values paired with respect for the values of others• Dialogue as value exploration and clarification
Pre dialogical iss esPre‐dialogical issues
• Discussing ethical issues in relation to bioenergy has a tendency of ending up withpeople discussing radically different things at the same timethe same time
• It can be debated what should be debated– Risk management or also risk understanding
– Specific issues or also general issues
– Existing technologies or also visions of the future
• Taks before entering the dialogue
– Figure out how to understand my own values and the consequences of them in light of the technologicalpossibilities
– Figure out how to frame the public discussion, so thatno one perspective will monopolize the debate
– Decide what the succes criterium is: find consensus, reach compromise or become wiser – or all of them?

• But it is hard to argue against the value of clarifying what is actually discussed
Ethics as identification of individualvalues
Ethics as framing the discussion
Ethics as decision‐making
Applicationlevel
Policy level
Symbolism
The modest goal
• Establishing a real dialogue will not ensure– Consensus– General acceptance of the solutions we choose
• But it might ensure– Public participation p p– Democratic process– Socially robust acions
• Accept of the policy by the majority• Accept of the process by the minority
• One of the very important tasks of applied ethicsis to facilitate this dialogue

• The potential of bioenergy is
significant but it is conditional
to many ethical and practical
dimensions
www.greenpeace.fi/palmuoljy
Ethical dimensions of the bioenergy
• The consequences of bioenergy production to
– Fair distribution of the benefits and costs of
production
– Ownership and tenure rights, participatory rights
and access to justice of local and indigenous
people
– Food production
– Biodiversity and ecosystem balance
– GHG emissions and climate impact
www.greenpeace.fi/palmuoljy
The climate impact of bioenergy• The carbon-neutrality of bioenergy is based on the
conditional fact, that the net impact to the atmosphere
should remain neutral in the medium term, ie the
emissions are absorbed by the continuously grow of the
biomass
• IPCC: ”Emissions of CO2 from biomass fuels are
estimated and reported in the Agriculture, Forestry and
Land Use sector”
• Carbon-neutrality is conditional to the carbon accounting
rules of forestry and land use
– Current rules in UNFCCC and Kyoto Protocol do not fully
guarantee this, new REDD also includes potential loopholes
– RSPO sertificate currently ignores this
www.greenpeace.fi/palmuoljy
Biofuels booming• Greenhouse gases (GHG) and high prices for
fossil fuels have increased the interest
• EU and national renewable targets to replace
transport fuels further push the interest
• Raw materials: Palm, rapeseed (canola),
sunflower, soya, jatropha, algae, waste …
• Palm oil a leader, major investments planned
• Increasing pressure for large scale production
in tropical areas
www.greenpeace.fi/palmuoljy
Production of raw materials in tropical areas causes• Forest and peat land destruction
• Logging
• Drainage and burning
• GHG emissions
• Loss of biodiversity
• Competition for land
• Threatening food production
• Increased inequality between rich and poor
• Human rights violations
www.greenpeace.fi/palmuoljy
Indirect land use change (ILUC)• GHG reduction is main justification for interest
in biofuels and for public policies supporting
biofuels
• Substantial GHG emissions through land-use
changes arising from biofuels production
• Research increasingly indicates that these
GHG emissions can outweigh any savings
from using biofuels
• ILUC emissions must be included in EU and
national renewable targets

Case study: Southeast Asia• Tropical forest destruction is responsible for
20% of greenhouse gas (GHG) emissions in
the world
• Indonesia is the world’s third largest producer
of greenhouse gas emissions
• Forest destruction is the main cause for
Indonesia’s GHG emissions
www.greenpeace.fi/palmuoljy
Case study: Southeast Asia• Palm oil and pulp production are the main
drivers of deforestation in Southeast Asia
• Plantations established in forest areas to log
the forests for timber to fund first years before
the first palm oil crop
• The clearing of rain forest and peat land area
is driven by the growing demand for palm oil
• There is growing interest to use palm oil as
raw material for fuel
www.greenpeace.fi/palmuoljy
Palm oil production booming• In 20 years 3x more plantation area
• 90% of production in Southeast Asia
• In Indonesia more than 22x more land area,
increase by over 2100% in 20 years
• Most of palm oil still used in food and
cosmetics industry
• Growing demand of palm oil for fuel
www.greenpeace.fi/palmuoljy
• More production by large scale enterprises
• Companies work in both palm oil and pulp
business
• Increased number of conflicts every year
• People are violently driven away from their
land and homes
• According to Indonesian legislation the local
communities own their land but despite of this
the same areas are given to palm oil
corporations to establish plantations
Local impacts of palm oil production
www.greenpeace.fi/palmuoljy
Local impacts of palm oil production• Cheap labor force brought from other areas
• Local communities achieve no benefits: Lack
of groundwater, toxic chemicals use as
fertilizers poison environment, forest fires
cause environmental and health problems
• Environmental problems
• GHG emissions
www.greenpeace.fi/palmuoljy
Sustainable palm oil production?• Virtually impossible in large scale
• Roundtable on Sustainable Palm Oil
• GHG emissions caused by land use change
are not included in criteria and will not be
included in becoming years
• RSPO standard can not be used for

Urgency and need for real solutions• UN estimates that virtually all Southeast
Asian rain forests will be vanished by 2011 if
the growth in demand of palm oil continues
• Orangutans estimated to become extinct in 5
to 15 years
• There is no time to wait to find alternative raw
materials
• Palm oil must not be used as raw material for
fuel
www.greenpeace.fi/palmuoljy
Urgency and need for real solutions• Contemporary research proves that the
growing demand raw materials for fuel is
putting more pressure to establish new
plantations to rain forest and peat land areas
• Palm oil hasn’t been used much as raw
material for fuel and now the demand is about
to increace immensely
• No palm oil should be used for fuel as the
GHG emissions are worse than the ones from
fossil fuels
www.greenpeace.fi/palmuoljy
Urgency and need for real solutions• No palm oil based fuels to be subsidized as
environmentally friendly
• To reduce emissions resources must be
focused on more energy efficient cars and
improvement of traffic and transport
infrastructure and logistics
• Real solutions must be subsidized, for
example waste based fuels and energy
efficiency
www.greenpeace.fi/palmuoljy
Sustainable future of biofuels• More efficiency in
ALL technologies within the transport sector
• Strict efficiency standards for cars
• Phase-in of electrical drives

Steven Hunt Senior Consultant, Practical Action Consulting Research Theme Leader, DFID PISCES Programme (Policy Innovation Systems for Clean Energy Security) Coming from a background of product development consultancy for global brand-name firms, via project work in slum redevelopment, relief shelter, and wind turbine design, Steven works on the realisation of clean energy products and services in developing countries. Steven is currently managing and providing technical input into assignments in countries around Latin America, Africa and South Asia, and has recently led technology and policy studies on behalf of FAO, UNDP, World Bank, the EU Presidency and DFID amongst others. He was recently the project manager and lead author on the joint FAO-PISCES report entitled Small-Scale Bioenergy Initiatives: Brief description and preliminary lessons on livelihood impacts from case studies in Asia, Latin America and Africa available from www.pisces.or.ke/pubs Bioenergy and development policies – small-scale bioenergy initiatives Although discussion of bioenergy tends to be dominated by large scale production of liquid biofuels for transportation, this is only a fraction of the role which bioenergy plays in developing country economies. In rural areas, trade in fuelwood and charcoal is often second only to agriculture as a source of income to rural economies. Small scale initiatives around the developing world are piloting innovative methods of improving the convenience and sustainability of natural bioresource use, as well as more efficiently processing bioresidues from existing agriculture and forestry activities to support local energy access and livelihoods. Other initiatives, often involving networks and co-operatives of farmers, are also developing purpose grown biofuels with an emphasis on meeting productive energy needs reducing drudgery and breaking local dependency on fluctuating oil costs. Such initiatives provide valuable lessons about cyclical and more efficient use of natural resources, and how the sustainable production and use of bioenergy could assist in the development of rural economies, rather than being primarily extractive. However, such initiatives are often fragile with wider social and environmental benefits generally unvalued. Development policy has largely ignored such initiatives to date and has focused on the intense debate relating to larger, export-led privately-financed liquid biofuels development geared towards meeting green transport fuel demand in northern countries. An opportunity exists however to bring small-scale sustainable livelihoods-oriented bioenergy initiatives more into focus of development policy in order to much more directly support local energy access and create new livelihoods opportunities, both in bioenergy market systems, as well as in the productive use of the energy itself.

� The target for the consumption of renewable energy (38% of total) by 2020 is planned to be achieved largely by increasing biofuel consumption in Finland
� Small-scale wood burning to be continued at a high level 13 TWh (2005 →→→→→→→→)
� Forest chips to be increased from 6 TWh (2005) to 21 TWh, mostly in small power plants (<<20 MW)
� Wood pellets and agricultural biomass to be increased from0.1 TWh (2005) to 3 TWh, mostly in small power plants
� Bio-oils to be increased from 0 TWh (2005) to 6 TWh, half in motor vehicles
Conflict of the strategy with public health
� About one third of the small-scale wood burning in communities with substantial population
� No regulations for energy efficiency of the combustionappliances, no emission limits
� Even inappropriate boilers without water tank are allowed as primary heaters (fine PM mass emission ∼∼∼∼∼∼∼∼100-fold comparedto good combustion technology)
� No CE marking to advice the customers to buy low-emittingappliances
� Many of the small power plants (<20 MW) in the middle of the community
� No filtering of fine PM emissions, whether biomass, peat orheavy fuel oil are used

Rough estimate of the present diseaseburden from poor biomass combustion
� Hundreds of premature deaths due to excess fine PM (total ∼∼∼∼∼∼∼∼1300 per year in Finland as assessed by the Clean Air for Europe, CAFE project in 2005)
� Thousands of adult asthmatic or other respiratory diseasesubjects, and thousands of children, with impaired healthand restricted activity days due to excess fine PM
� Excess health costs in the order of tens of millions of euros per year in Finland (see CAFE 2005)
� Health risks among subjects with cardiovascular diseaseand health risks from gaseous pollutants (CO, VOC) poorlyknown
”Not-so-nice picture” of the societalburden from poor biomass combustion
� Newly retired people in good health and with a lot of sparetime change oil or electric heating in their 20- to 50-year old houses to inappropriate wood heating due to savingsin costs (wood mostly from own forest)
� Frank poisoning of other retired people with cardio-respiratory illnesses and small children & their mothers in neighbourhoods
� Tens-to-hundreds of official complaints in recent years bythe exposed people →→→→→→→→ mostly poor handling of the cases byofficials in municipalities →→→→ appeals to administrative courtsand occasionally to civil courts →→→→ variable decisions thatrarely help those who appealed
� Conflicts lasting for many years lead to poor relationsbetween neighbours, excess work by the administration etc.
Governmental control measures
� A statute for energy efficiency of the small-scale combustion appliances & emission limits first suggested to the Ministry of the Environment in 1997
� Appeal of three health NGOs to the political groups in the Parliament started preparation of the statute in 2005
� Statute ready for implementation in 2007 but not done
� The Ministry of Social Affairs and Health gives instructions to municipalities on the health aspects of poor wood combustion (STTV 6/2008)
� These instructions are nearly toothless without the statuteon energy efficiency & emission limits
� The Ministry of the Environment has prepared a statute to be given to the Parliament on very loose PM emission limits for small-scale power plants (said to represent BAT)
What should be done better?
� A statute for energy efficiency of the small-scale
combustion appliances & emission limits right now!
� Even the Finnish industry manufacturing these appliances
wants the statute →→→→→→→→ no national reference for markets of low-emitting appliances
� Ban of inappropriate boilers without water tank
� PM emission limits for small-scale power plants should be
tightened to represent current BAT in the Parliament (if not
before by The Ministry of the Environment)
� The central, regional and local governments should start be bear better responsibility for the health aspects of
bioenergy to avoid excess premature deaths & new cases
and exacerbations of chronic cardiorespiratory diseases

Why is there a need for strict control of
particulate air pollution?
� Fine particulate matter (PM2.5; diameter ≤≤≤≤ 2.5 µµµµm) causes the largest disease burden of all environmental factors to the European populations
� Current long-term PM2.5 exposures associated with ∼350 000 premature annual deaths, hospital admissions, and restrictedactivity in tens of millions of children and subjects with chroniccardiovascular or pulmonary disease in the EU25 (CAFE 2005)
� No clear threshold for health effects at low daily average PM10/ PM2.5 concentrations (< 5 µµµµg/m3), and even 1-hour peak concen-trations associated with severe respiratory and cardiac events
� Ultrafine particles (diameter ≤≤≤≤ 0.1 µµµµm) and coarse thoracicparticles (PM10-2.5; diameter 2.5-10 µµµµm) associated with healtheffects that are independent of concurrent PM2.5 levels
EU-CAFE assessment on the health impacts
of PM2.5 in the EU25 in 2000 (population ∼∼∼∼450 million)
� Premature death cases 347 900
� Life years lost 3 618 700
� Infant death cases 677
� New cases of chronic bronchitis 163 800
� Hospital admission cases (heart + lung) 100 300
� Lower respiratory symptom days (5-14 y) 192 756 400
� Restricted activity days (15-64 y) 347 687 000
� Value of health damage 268 - 781 billion € / year

CAFE assessment on health impacts of
PM2.5 in three Nordic countries (2000)(population ∼∼∼∼20 million)
� DK: premature death cases 3 270
� FI: premature death cases 1 270
� SE: premature death cases 3 280
� New cases of chronic bronchitis 3 510
� Hospital admission cases (lung + heart) 2 143
� Lower respiratory symptom days (5-14 y) > 4.4 million
� Restricted activity days in adults (15-64 y) > 7.2 million
� Value of health damage 5,8 – 17,6 billion € / year
Which sources and chemical compositions
are the most hazardous to health?
� Epidemiological evidence of variable strength on the harmfulness of traffic exhaust, small-scale coal and woodcombustion, locally or transnationally transported wild-fireand resuspended road dust particles
� Reasonably strong epidemiological evidence on soot(EC/BC); suggestive toxicological evidence on transitionmetals (e.g. Cu, Ni, V, Fe, Zn), PAH-compounds, quinonesand soil minerals
� Epidemiological and toxicological studies suggest that PM compositions originating from the same combustion sourcemay have different impacts on air quality and health in different climates and seasons (e.g. via transformation of the organics)
� Epidemiological and toxicological studies suggest that freshPM compositions from local combustion sources may bemore potent per mass unit than the aged compositions fromregional and long-range transport

Bioenergy and emissions
� Bioenergy use is promoted in decentralised heating systems,
but they are currently less energy efficient and cause more air
quality problems than large power plants
� Domestic wood combustion is responsible for 25% of all PM2.5
emissions, 65% of PAH emissions and 25% of all NMVOC
emissions in Finland – situation similar to many other EU-
countries (Karvosenoja 2004; Karvosenoja et al. 2008)
� The main reasons for large PM2.5 emissions from domestic
heating appliances (commonly 20 kW) are poor combustion
technology, poor biomass fuel quality and operational errors of
the users (e.g., overloading, restriction of air supply)
� Small heating plants (commonly 20 MW) using biomass, peat or
heavy fuel oil have no obligation to use the most efficient flue
gas after-treatment technology - no PM emission limits!

Experimental human and animal studies on
biomass combustion emissions
� Controlled acute exposures of human subjects to diluted
combustion emissions in exposure chamber to answer few,
selected scientific questions (Barregård et al. 2007; Sandström et al.)
� Monitoring of respiratory and cardiovascular functions, and
biochemical response markers in a limited number of experiments
� Mild inflammation and increased blood coagulation reported
� Controlled acute, subacute and subchronic exposures of animals
(rats, mice) to aerosolized or liquid-suspended emission particles
from biomass combustion to answer a somewhat larger number of
selected scientific questions (see e.g. Zelikoff et al. 2002)
� Monitoring of respiratory and cardiovascular functions, biochemical
response markers, and structural changes in the lungs
� Mild inflammation, decreased host defence against bacterial
infections etc. reported
Experimental cell studies on biomass
combustion emissions
� Controlled exposures of key target cells (macrophages, epithelial
cells) of the respiratory tract to liquid-suspended emission
particles from biomass combustion to answer a larger number of
scientific questions (see, e.g. Zelikoff et al. 2002) and to aid
technological development of combustion installations
� Measurement of biochemical markers of a wide range of
mechanistic health end points (inflammation, genotoxicity,
cytotoxicity, cell cycle) in mammalian cells
� Inflammatory and cytotoxic activities of air particles are
anticipated to be linked with the non-carcinogenic respiratory and
cardiovascular effects, and genotoxic acitivity with the lung cancer
risk among human subjects
� Increased inflammatory activity, cell death and genotoxicity, and
cell cycle arrest reported

Wildfire smoke episodes 1
� Smoke-haze episodes from forest, bush and peat fires arecommon features in Southern and Northern Europe
� Incomplete biomass combustion gives rise to large amounts of potentially harmful particulate (PM2.5, PAH) and gaseous (CO, NMVOC) emissions
� The combustion-derived pollutants can episodically causeprofound increases in PM10 and PM2.5 concentrations, and in the carbonaceous composition of the particulate mass
� The smoke-haze episodes appear annually in certain months and can last for weeks each time, and the episodes are likely to become more prevalent with climate change in Europe
⇒⇒⇒⇒ Smoke aerosols affect populations not only locally but alsoat distances hundreds or thousands of kilometres away
⇒⇒⇒⇒ Premature deaths of about 10 subjects with cardiorespiratorydisease per typical episode week has been estimated forsouthern Finland (Hänninen et al. 2009)
Wildfire smoke episodes 2
Helsinki, Finland – annual data 2006 by FMI
The impacts of (1) local small-scale wood combustion and (2 and 4) episodes of
wild fire smoke on the PM2.5 (upper panel) and organic carbon (lower panel)
concentrations were identified with the help of specific marker – levoglucosan
(blue lines); (3) the low biomass-smoke June-July (Saarnio et al., submitted).

Wildfire smoke episodes 3
Helsinki, Finland – 10 August 2006
The location of wildfires and their emissions can be assessed fromsatellite images, and the transportation of smoke-haze can be modelled(Saarikoski et al., 2007).
NORDAIR-BIOS recommendation on
wildfire smoke episodes
� National internet portals should be established for
presentation and instantaneous dissemination of on-line air
quality data collected from continuously operating local
monitoring networks in order to facilitate early detection of
regional episodes of particulate air pollution caused by
transnational transport of forest fire or wildfire smoke-haze
� Early warning of the susceptible population groups such as
elderly subjects with chronic cardiovascular or respiratory
disease and asthmatic subjects of all ages
� The National Reference Laboratories of Air Quality
Monitoring in the Nordic countries are recommended to share
on-line with each other their pooled on-line air quality data
11
NORDAIR-BIOS & BIOMASS-PM
recommendations on small-scale systems
Measures have to be implemented to reduce PM emissions
from residential biomass combustion systems:
� The future increase in biomass energy should be primarily made in
community-level plants with high-quality controls for the combustion
process and emissions
� Substitution of old residential combustion devices by modern low
emission systems should be promoted
� Provision of appropriate “user training” for non-automatically fed
systems (stoves/boilers)
� Support of R&D of low-dust combustion technologies
� Support of R&D and application of appropriate filter technologies for
residential biomass combustion systems
� Emission limits and test standards should be harmonized on a
European level
BIOMASS-PM research needs 1
� More information on the impact of real-life user practices
on particulate emissions is needed as well as on the
overall impact of small-scale biomass combustion
emissions on local and regional air quality
� More information is needed about the association between
different kinds of particulate matter emissions from
biomass combustion installations and their adverse health
effect potential as assessed by experimental human and
animal studies
12
BIOMASS-PM research needs 2
� Cell studies should provide a generic concept on the
association of inorganic and organic chemical
constituents with the inflammatory, cytotoxic and
genotoxic activities of particulate emissions from a series
of combustion technologies and biofuels
� Interdisciplinary research between the aerosol scientists
and epidemiologists:
� New short-term panel studies with personal exposure monitoring and source-specific exposure modelling are needed
� GIS-based cohort studies on chronic respiratory and cardiovascular diseases and cancer are needed
