Paradigm Shift from Projects to Programs

How do we evaluate climate change projects?

Gaps in the evaluation process

3. The Kyoto Protocol provides the basis for evaluating
climate change projects
Kyoto Protocol (1997)
The Protocol creates legally binding obligations for 38
industrialized countries to return their emissions of
greenhouse gases to an average of 5% below their 1990 levels
by 2012
Marrakech Accords (2001)
Define the principles of the Kyoto Protocol’s flexible
mechanisms: the Clean Development Mechanism (CDM),
Joint Implementation (JI) and Emissions Trading (ET)
3
4. The role of the Clean Development Mechanism (CDM)
Advantages for developed
countries:
Developed countries
can reduce
emissions anywhere
in the world
They can count
these reductions
towards their own
targets
CDM allows
developed countries
to generate ‘carbon
credits’ (Certified
Emission
Reductions, CERs)
in developing
countries
relatively low-cost &
politically acceptable
Advantages for developing
countries:
inward investment,
environmental & technology
benefits

market

7. ‘Kyoto gases’ that can earn credits
There are over 30 atmospheric greenhouse gases…But only 6
attract carbon credits:
•
Carbon dioxide (CO2)
•
Methane (CH4)
•
Nitrous oxide (N2O)
•
Perfluorocarbons (CxFx)
•
Hydrofluorocarbons (HFCs)
•
Relevant to biocarbon & industrial
projects
Sulfur hexaflouride (SF6)
Relevant to
industrial projects
7
8. Each of these gases has a different warming potential
Each of these gases has a different ‘radiative forcing’
capability and a different atmospheric residence time
Need for a ‘common currency’, so that all carbon credits are
denominated in the same way
Solution: develop a relative scale, using CO2 as a reference gas

measured relative to CO2
e.g. methane is 21 times more
potent as a greenhouse gas
than CO2
e.g. sulfur hexafluoride is
24,000 more potent!

Carbon credits are always
expressed in terms of ‘carbon
dioxide equivalence’ (CO2e)
e.g. 1 tonne of CO2 = 1 tCO2e
(= 1 carbon credit = 1 CER)
e.g. 2 tonnes of CH4 = 42 tCO2e
(= 42 carbon credits = 42 CERs)
e.g. 2 tonnes of SF6 = 47,800 tCO2e
(= 47,800 carbon credits
= 47.8 kCERs)
10
11. Additionality
Environmental additionality – the project produces fewer
greenhouse gas emissions than the baseline scenario
It is essential that the project achieve environmental
additionality – otherwise, it will not generate any carbon
credits!
However, the project developer must also usually
demonstrate that, without carbon revenues, the project
would not be viable and/or commercially attractive – this
is known as financial additionality
11
12. Additionality – benchmark analysis
Revenue / NPV / IRR
Choose an appropriate financial indicator and compare it
with a relevant benchmark value: e.g. required return on
capital or internal company benchmark

13. Some examples of additionality
?
Capturing methane from an urban landfill and flaring it
— Carbon credits represent the only source of income
for undertaking this activity
Capturing methane from an urban landfill and utilizing it to
generate electricity
— Project developer would have to demonstrate that
the electricity revenue alone would not make this
project attractive
Building a large hydro project for the grid in Ethiopia
— Questionable additionality: there is already plenty of
hydro activity in Ethiopia
13
14. Crediting period
CDM mitigation projects
• Project developers have two crediting period options:
– A maximum of 7 years, which can be renewed up to 2 times
(i.e. a potential total crediting period of 21 years)
– A maximum of 10 years, with no option for renewal
CDM sequestration projects (forestry)
• Project developers have two crediting period options:
– A maximum of 20 years, which can be renewed up to 2 times
(i.e. a potential total crediting period of 60 years)
– A maximum of 30 years, with no option for renewal

How do we evaluate climate change
projects?
The current project cycle
Gaps in the evaluation process
From projects to programs
28
29. Limitations of current evaluation process
Each project is evaluated in isolation
Benefits outside project boundary are discounted
“Additionality” is difficult to define
NPV/IRR is the single metric
Impacts of leveraging and collateral on asset
value are not fully considered
30. Limitations of CDM market
Projects are financed sequentially starting with those
generating the most CERs at lowest cost
Bias towards funding larger stand-alone projects
Bias towards mitigation and away from adaptation
Monitoring is costly and often impractical -- flaw in project
design leading to implementation problems
Lack of uniform registry of CERs
31. Lack of an “enabling environment”
Regulatory and institutional support is often lacking
Evaluation methods and guidelines are complicated
Markets for CERs often very “thin” internationally
Small countries and marginal populations unable to
participate in CDM

36. Leverage affects value of CERs
Incorporate collateral into evaluation models so that
equilibrium determines leverage, not just rate of interest
Variations in leverage causes fluctuations in CER values
In absence of interventions, leverage becomes too high in
boom times and too low in bad times
“Natural buyer” hypothesis has been used in
Macroeconomics to study financial cycles -- used to model
market for CERs
Provides guidance to regulators on when to restrict
leverage
