1A research programme focused on how to assess
benefits and costs in the area of environmental
decision-making. Aims at developing theory and
methods for applying cost-benefit analysis (CBA)
to problems involving environmental policies and
management. Financed by the Swedish EPA. Thematic
areas Distributional issues Risk,
uncertainty and resource dynamics Valuation
and benefit transfer Goal conflicts
2Goal conflicts and side gains Connections and
interactions between policy measures and
environmental objectives
- Actions taken to achieve a specific social
objective generally have effects on other social
objectives positive or negative - How does the target level for one environmental
goal affect the cost and possibilities to reach
another environmental goal?

Purpose
- The purpose is to analyze the goal conflict
between the environmental objectives Sustainable
Forests and Reduced Climate Impact. - by
- Assessing possible effects of a implementation of
the objective sustainable Forests on the supplied
quantity of biofuels within the forest sector,
and thereby the effect on the goal concerning
emissions of greenhouse gases.
4Reduced Climate Impact
- Average emissions of greenhouse gases for the
period 200812 should be at least 4 lower than
in 1990 (calculated as carbon dioxide
equivalents) - No allowance is to be made for uptake by carbon
sinks or for flexible mechanisms. - Implemented e.g. carbon taxes, quota systems for
the electricity market and trough trading with
emission credits. - The part of the energy sector that can substitute
away from non-renewable fuels have, or will, do so

7Sustainable Forest
- (Interim targets)
- Long-term protection of forest land
- A further 900,000 hectares of forest land of high
conservation value will be excluded from forest
production by the year 2010. - Enhanced biological diversity
- Increasing the quantity of hard dead wood by at
least 40 throughout the country and considerably
more in areas where biological diversity is
particularly at risk

11- Forest owners are assumed to choose the
quantities of different assortments that maximize
profits at given prices. This is made conditional
on the forest assets and cutting costs. The
remaining actors in the model use raw materials
from the forest as an input in their production
process the pulp industry, the saw mill industry
and the heating industry. - We assume that pulp mills use labor, energy and
capital to convert pulpwood into pulp, and that
the saw mills and heating plants use the same
types of production factors to convert sawtimber
into sawn goods and wood fuels into heating. - Finally we allow for technological development
(by including a linear technological progress
term (t)) and for lags in the adjustment to price
change (by a partial adjustment term (xi(t-1))) .
This means that if a price changes, demand does
not necessarily adjust completely within one
period. This also means that we can estimate both
short run (within one year) and intermediate run
effects.
12Data
- Annual time series data covering the period
1966-2006 - Unsurprisingly - this relatively long period of
time contain some changes with respect to e.g. - which agency that produces certain statistics.
- what they measure.
- how they measure it.
- there are occasions where two subseries
have had to be fitted against each other with
help of a scalar. - Estimation through 3SLS.

15Conclusions
- Protection of forests will decrease the
supply/demand of forest fuel. - The decrease in supply of wood fuel will decrease
output from district heating plants by 2 TWh. If
oil is used as substitute Swedish CO2 emissions
will increase rather than decrease, as the goal
Reduced Climate Impact prescribes. - A cost-benefit analysis of one environmental goal
will be contingent on target levels for other
environmental goals.
16Biofuels or Biodiversity An Analysis of the Goal
Conflict between Reduced Climate Impact and
Biological Diversity

Purpose
- The purpose is to analyze the goal conflict
between the environmental objectives Reduced
Climate Impact and A Rich Diversity of Plant and
Animal Life. - by
- Assessing possible effects of a implementation of
the objective Reduced Climate Impact through
increased implementation of stump harvesting in
northern Sweden, and the consequent effects on
biodiversity.
17Reduced Climate Impact
- Average emissions of greenhouse gases for the
period 200812 should be at least 4 lower than
in 1990 (with current policies, the expected
outcome is about 15 below 1990) - By 2020 emissions of greenhouse gases in Sweden,
from activities not included in the EU Emissions
Trading Scheme, will be reduced by 40 compared
with 1990. (with current policies, the expected
outcome in 2020 is about 25 below 1990)
18A Rich Diversity of Plant and Animal Life
- (Interim targets)
- The loss of biodiversity in Sweden should be
halted by 2010 - Enhanced biological diversity
- Given the importance of CWD (Coarse Woody Debris)
for forest biodiversity another sub-goal is to
increase dead wood volume.
19Stump harvesting as a way of increasing the
supply of wood fuel.
- The main inspiration for stump harvesting in
Sweden comes from Finland. - Deemed as very interesting by Swedish forest
companies such as SCA and StoraEnso.
- Currently (2010), stump harvesting is conducted
by StoraEnso in the counties of
Västergötland, Östergötland, Småland and
Halland.
20The Model
- Two parts
- A model describing the interlinkages between the
different
parts of the forest sector, - A second model describing the relation between
stump harvesting and
biodiversity via the changes in dead wood. - The region is logging area one an
administrative district roughly
corresponding to the four northernmost counties
in Sweden. The motive for choosing this area is
that the ecological data is mainly relevant for
this area. - Again, the parameters for the forest sector model
are estimated with 3SLS.
21The Model (cont.)
- The ecological model originates from an
experiment conducted at ten localities situated
in the counties of Västerbotten and
Västernorrland - basically the same region of
Sweden. - The data allows for predictions of the effects
from stump harvesting on population densities of
saproxylic beetles - used as proxy for
biodiversity. - The ecological analysis showed that stump
harvesting will reduce the population density of
saproxylic beetles per ha in a an approximately
one to one relationship, i.e. if 80 percent of
the stumps are harvested about 80 percent of the
population remaining on the clear-cut is gone.
22Simulations
- In the simulations we will assume that the demand
for biofuels, originating from heating plants
within cutting area one, will increase by 3 TWh
(equivalent to approximately 1.6 million m3
wood). - Furthermore, we assume that about 20 percent (350
000 m3fub) of this increase will consist of
demand of primary forest fuel. - In the simulations, this will translate to a 30
percent exogenous increase in the demand for
primary forest fuel at every price level.
23Results
- Our calculations for this sparsely populated
region in Sweden give at hand that about 3.4 of
the clear-cut area need to be subjected to stump
harvest every year to provide the required volume
of forest fuel. - This means that future stump harvesting projects,
with the aim to fulfill the objective Reduced
Climate Impact, might overturn the objective A
Rich Diversity of Plant and Animal Life due to
the dramatic reduction in dead wood volume on
clear-cuts. - No nonmarket value of lost biodiversity has been
estimated in this paper, but it is clear that a
cost-benefit analysis of an increased use of
biofuels through stump harvesting that does not
take the goal conflict with respect to
biodiversity into account, would seriously
underestimate the costs of such a solution to the
increased demand for carbon-neutral energy.
