6.1b and 12.5c of the KP state that project’s activities must lead to carbon
benefits that are additional to a “business-as-usual” scenario (=additionality).
The quantification of the additional carbon benefits requires the development
of a baseline scenario against which changes in carbon pools in the with-project
case can be compared. In other words, it has to be estimated what would
have happened in the absence of the project. This leads to one of the greatest
challenges in the project design because land use change and changes in
forest management practices are hard to predict.
The
difficulty to predict likely changes in land use and their corresponding
carbon in the without-project cases depend on changing socio-economic,
cultural and political conditions. Therefore, geo-spatial information on
biophysical drivers and socio-economic variables as well as on land use
and forest at different dates (recent and historic) is required to be combined
by spatial modelling in order to simulate future trends. Generally speaking
it is useful to consider two cases of baseline determination. In the first
case the project has to be assessed in isolation from a broader economic
system. In the second case, the project has to be integrally linked with
a larger economic and environmental system, so that baseline determination
must consider the entire system.
Detailed
information from EO data on forestry and land use within the project activity
boundaries but also information outside is required in order to determine
the negative or positive project side effects (=leakage). In this context
leakage is used to determine positive (=spillover) but also negative project
effects (e.g. increased fuelwood consumption outside a newly protected
area). When however considering the typically project duration (30 to 99
years) the shortcomings of such static (=fixed) baseline assessments become
obvious and it was for this reason that some projects have implemented
a dynamic (=adjustable) baseline assessment. The latter requires knowledge
on generalised land-use trends (change indices) and has a large credibility
advantage over a static baseline because adjustments to new economical,
ecological and political development trends can be made throughout the
project duration.
Conventional
method:
No
standard methods exist for setting baselines. In a number of already existing
demonstration projects different approaches for establishing baselines
are in use. These are ranging from simple logical arguments based on adjusting
observed trends or assuming the continuation of business-as-usual trends
to spatial modelling. Quantification of carbon is mostly done in proxy
areas within control plots. In some cases it is only based on literature.
Such input data may lead to wrong assumptions at project registration and
baseline calculation and thereby increase the financial risk of the project.

EO
derived product advantages and innovation:
EO
is a proven source for forest/land-cover mapping, for producing statistics
on land use and it is the only geodata source that provides comparable
data from the Earth surface for the last decades. The data can contribute
objective geo-spatially referenced information with a statistically assessed
level of precision. The generalised knowledge of the project area can be
used for further planning purposes and subsequent stratification. Where
necessary, the generalised information can be combined with higher resolution
information for estimation of the baseline/leakage.
Advantage
for project-developer and cost benefit:
The
risk associated with project registration and conduction can be reduced
due to sound available land cover/use input data. While the cost of EO
with moderate and medium resolution data is relatively low (due to incommensurable
results with conventional methods no direct cost comparison is made) it
also allows for observation of large areas. On the performance side the
information derived from EO for geo-spatial modelling adds a significant
advantage for projecting the without-project baseline in a more objective
way and leads in the case of adjustable baselines to more plausible off-set
scenarios.
EO
Product Examples:
The
EO derived information is delivered in form of maps and statistics and
serves as numerical input into spatial models for verifying the without-project
baselines. Theoretically, the spatial extend of gathering data can be expanded
to any size of a system area.
