CDM MethodologyWorld Bank Carbon Finance:Interpretations and Approaches to Baselines, Monitoring and Calculation of Emission Reductions Bonn, 6 June 2003Johannes Heister – PCF, Carbon Finance Unit, World Bank
Assumptions and Principles • Know what we want to achieve. • Do we have a common understanding of the objective? • The world is a well-structured, intelligible place. • Are we able to understand and predict human actions and developments through analysis and synthesis? • Information (facts) plus rationality (reasoning). • Are we able to collect a complete set of relevant observations and produce consistent arguments? • Methodologies reduce complexity and need for judgments. • Methodologies must have discriminatory power, but how do we choose the “right” methodology? • Keep a skeptical mind. • Are we willing to correct predictions on the basis of new observations?
PCF baseline and monitoring philosophy • Produce highly credible ERs • carry a public premium: they promote the CDM • lack of integrity can damage the CDM. • Experiment! • find out what works: as a methodology and for the CDM as a market based instrument (reasonable requirements) • with transparency, methodological rigor and intellectual honesty (prototype) • evolutionary approach: be ready to change course • Political dimension • Baseline methods can have distributional implications • political guidance therefore necessary (EB, Parties)
What is the PCF approach to additionality and baselines? CO2 Emissions Baseline scenarioCO2 emissions (that would occur) Real, measurable and long-term Additional CO2emissions reduction CDM project CO2 emissions (observable) Years baseline study
Additionality: criteria investment program financial regulatory technological emissions Baseline: methods project specific standard baseline Emission Reductions:Genesis of a seemingly simple idea 1995: Activities Implemented Jointly (AIJ) pilot phase Projects Emission Reductions ? 1997 Kyoto Protocol: “Reductions in emissions that are additional to any that would occur in the absence of the certified project activity.”
Additionality of a project Baseline scenario project specific Emission Reductions:Genesis of a seemingly simple idea 2001: Marrakech Accord: “Environmental additionality”: = emission reductions Baseline: = scenario that represents emissions … Emission reductions estimate Another interpretation: Emissions baseline sector wide ? standard ? Additionality (of a technology)
Emissions baseline Ex ante projection, conservativeness Project additionality “but-for” test? Emission Reductions:Genesis of a seemingly simple idea 2003: Project Design Document: “Project additionality”: “Description of how the baseline methodology addresses the calculation of baseline emissions and the determination of project additionality” 5th Methodology Panel: “Emissions baseline”: Ex post calculations of baseline emission rates shall not be used. The baseline emission rates must be calculated and reported ex ante. Emission reductions calculation
Issues • Project versus environmental additionality: => but-for test or “stylized” baseline methodologies? • Ex ante factors & conservativeness:=> or monitoring and ex post factors • Scope of methodologies=> role of Operational Entities • PDD Format
COP-7 – defined baseline for CDM What is a baseline ?? (44)The baseline is the scenario that: “reasonably represents GHG emissions that would occur in the absence of the proposed project activity”
Scenario defined Webster’s dictionary: • A sequence of events especially imagined. • An account or synopsis of a possible course of actions or events. Baseline scenario defined WB CF definition: The the most likely course of action and development over
PCF – baseline scenarios defined: • The relevant baseline scenario is the most likely course of action and development over time. • The baseline scenario can include development alternatives that may be realized at yet unknown points in time, if such developments can reasonably be anticipated. • The baseline scenario is not an emissions baseline (such as an emissions factor).
How to measure ERs? CO2 Emissions monitor using • time indicators and proxy variables baseline emissions (hypothetical, partly monitorable) monitoring plan & calculation concept Additional ERs measure directly • or using emission indicators project emissions (actual) Years
Why is a monitoring methodology important? • More information on how a baseline scenario develops becomes available over time. (Increased credibility) • The monitoring concept can deal with issues that the baseline study cannot address. (Reduced complexity) • A good monitoring concept ensures the credibility and verifiability of the maximum number of ERs. (Less conservative)
Two components of monitoring plans • Emission reduction calculation concept • Rational and assumptions • Variables, parameters, formulae • Instructions for data collection ===> For project – and for baseline, too?
WB Carbon Finance: project design involves three distinct elements. Baseline scenario Calculation concept Emission reductions Monitoring Plan
How to project ERs • Use the project design (baseline, calculation concept) • Make reasonable assumptions about the data to be monitored • Run the calculation tool (spreadsheets)
What is the Emission Reduction Study? • Forecasts • emissions in baseline scenario • emissions in project scenario • expected emission reductions • Establishes environmental additionality • Provides structured risk information by simulating ER calculation (sensitivity analysis) • Is a basis for informed negotiations

Two Baseline Filters • Boundary for possible baseline scenarios • where do you look? • Possible alternative scenarios to provide service • first filter: • identify constraints: legal, political, economic, costs ... • Plausible alternative scenarios (short list) • second filter: • chose baseline method: justify why most appropriate • apply method and determine: • => the most likely baseline scenario
How to structure baseline studies? Information on: CDM modalities, country and sector, legal and other constraints and requirement, proposed project, project context etc. Possible baseline scenarios Possible baseline methods Constraints and requirements Criteria for baseline method selection Plausible baseline scenarios (shortlist) Baseline method selected and justified Baseline scenariodetermined Monitoring and ER calculation concept
Ten rules on baselines • Each project must have a baseline. • The baseline must be established on a project-specific basis (for now), and in a transparent and conservative manner. • The baseline is the scenario that describes the most likely course of action and development in time (including alternative futures if anticipated and observable). • Scenarios are concrete: a sequence of decisions and events, a physical configuration, not simply a trend or a projection (of emissions) or an emissions baseline. • The baseline scenario is selected from a number of plausible scenarios, which must include the proposed project.
Ten rules on baselines • The selection is made by applying an appropriate baseline method, which builds on one of the Marrakesh approaches. • The baseline method must be justified: it must be an appropriate simulation of the decision making regarding the proposed project. • “Environmental” additionality is the only relevant additionality criterion; it requires only to show that the difference between projected baseline and project emissions is positive. • Aspects of both the project and the baseline scenario should be monitored, wherever possible at reasonable costs. • Baseline determination and monitoring / calculation of emission reductions is done by different, yet complementary methods.
Power Sector Projects System capacity Thermal Dispatchmargin Dispatch Hydro Base load Coal Coal Wind additional? Base load capacity replacement Major capacity addition Micro capacity addition
Grid connected power projects • Project expands generation capacity • Baseline scenario often well known: usually • the existing power grid and generation capacity • plus the power expansions path over time • Often unknown: Would the project be part of system expansion? I.e. … part of the baseline scenario? • Cost / kWh test: Are generation costs higher than alternative options?
Baselines for power projects • Comparison of investment alternatives on the basis of cost per kWh is typically used in planning of power system expansions. • Since there are only two alternative scenarios • The power system with the project • The power system without the project • a cost criterion is used to determine the baseline scenario. • Methodology: step-by-step instruction on how to use the criterion
Three least cost baseline methods for power projects • Run expansion planning model with project: is project not being picked up by the model? • Use expansion planning model to determine long-run marginal cost (LRMC): is project cost (per kWh) higher than LRMC? • Determine low/least cost project to represent expansion option: is project cost higher than cost of comparable expansion option? => If yes: the baseline is the power system without the proposed project
Calculation concepts for power sector emissions reductions? • Project-by-project dispatch margin analysis? • Ex post monitoring: Which power source is displaced at the operating margin? • Central coordination to prevent double counting of displaced marginal generation • Sector averages, e.g. combined build and operating margin • Simple and inexpensive, no central coordination needed • Can grossly over- or underestimate actual ERs • Ex post vs. ex ante emission factors
