A handful of projects have submitted requests to include new baseline<br />
scenarios, with variable level of success (see following section on baseline<br />
and additionality). Other projects may be diverting too much in terms of their<br />
methodological approach and have been recommended by the MP to apply<br />
similar, yet different methodologies than ACM0006 (see Box 43).<br />
Revision to<br />
include Heat only<br />
Boilers rejected<br />
Box 43: Fuel switch projects involving heat generation only<br />
A request for revision 291 suggested that a project involving a fuel switch from<br />
fossil fuel to biomass residues in a heat-only boilers be eligible under ACM0006.<br />
The MP explained that the project was not eligible because it is not appropriate<br />
to assume that only fossil fuel would be used in the baseline scenario, more so<br />
considering that historically, boilers have generated heat using biomass residues.<br />
Additionally, the proponent mentioned that the project could use different types<br />
of biomass than biomass residues throughout the crediting period, which was<br />
inconsistent with ACM0006. The MP recommended the project proponent to<br />
consider using AM0036, which had specifically been created for fuel switch from<br />
fossil fuel to biomass residues in heat-only boilers (the methodology had not<br />
been approved when the request had been submitted). However, the MP warned<br />
that, like ACM0006, AM0036 did not allow the use of biomass types other than<br />
biomass residues.<br />

Project Boundary<br />
Project Boundary<br />
includes Plant,<br />
Transport and<br />
Waste Disposal<br />
Site<br />
The project boundary shall include all the sites and transportation routes<br />
where emissions arise as a result of the project. These include the site where<br />
the power plant or retrofit is implemented, the site where the biomass<br />
residues are produced, the transportation routes between the site(s) where<br />
the biomass residues are sourced and the project’s power plant, and the<br />
site(s) where the biomass residues would have been dumped or left to decay<br />
in the absence of the project. The project boundary should also include all<br />
the power plants connected to the grid the project activity is connected to.<br />
To determine the spatial extent of the project’s grid and calculate the project’s<br />
build margin (BM) and operating margin (OM), project proponents should<br />
refer to the latest version of ACM0002 (see section 5.2.3).<br />
Baseline scenario and additionality<br />
Three Elements of<br />
Baseline Scenario:<br />
Power, Waste<br />
Treatment, Heat<br />
In determining their project’s baseline scenario, project proponents should<br />
first identify all credible alternatives with respect to:<br />
1. How power would be generated in the project area in the absence of the<br />
project;<br />
2. The treatment of the biomass residues in the absence of the project;<br />
3. How the heat the project proposes to produce would be generated in the<br />
absence of the project (specific to cogeneration power plants).<br />
Matrix of 20<br />
Baseline Scenario<br />
Options<br />
ACM0006 provides several plausible alternative baseline scenarios for each<br />
of the aforementioned categories. Upon identifying the most plausible<br />
baseline alternatives for power generation, heat generation, and biomass<br />
handling, project proponents should identify all realistic combinations of the<br />
three. Project proponents must then verify whether the identified combined<br />
baseline scenario is included in the list of applicable baseline scenarios found<br />
in ACM0006. In total, ACM0006 (version 6) proposes 20 different combined<br />
