Letaba Biomass to Energy PDD - MyClimate

SECTION E. Estimation of GHG emissions by sources
E.1. Estimate of GHG emissions by sources:
PROJECT DESIGN DOCUMENT FORM (GS-VER-PDD)
Voluntary Offset Projects - Version 01
Phases 1 & 2 Ecologically sound fuel switch to biomass with reduced energy requirement
No formulae are needed once the fuel switches are complete as emissions by sources will be zero – fuel source
(sawdust) is a CO2 neutral source of energy. The transport of biomass will cause a positive leakage and thus need
not be considered. The emissions reduction will equal the baseline which will be determined as in Annex 2.
Phase 3 AMS II.D Energy efficiency and fuel switching measures for industrial facilities
This template shall not be altered. It shall be completed without modifying/adding headings or logo, format or font.

No additional formulae are needed. The project emissions will be zero as waste heat will be used to drive the cooling
process.
E.2. Estimated leakage:
As expected above no leakage is expected
E.3. The sum of E.1 and E.2 representing the project activity emissions:
For the estimated period of a year after the project start date until Phase 3 is implemented there will be project
emissions from Phase 3 equaling the baseline emissions for Phase 3 (5 125 tonnes), thereafter the project emissions
will be zero. There will also be some Project emissions from phase 2 (5 116) as it is commissioned after phase 1.
The total is 10 241.
E.4. Estimated anthropogenic emissions by sources of greenhouse gases of the baseline:
Phase 1 Ecologically sound fuel switch to biomass with reduced energy requirement (fuel switch boilers)
Baseline emissions = Tonnes of peel dried in year y * emissions factor peel driers
= 3509 * 1.324364
= 4 647 tonnes per annum
Phase 2 Ecologically sound fuel switch to biomass with reduced energy requirement
Note: Because there is not really a “normal” year in terms of the division between single strength and citrus
concentrate production, projections are done using aggregate average (historical) coal use in the boilers. Once the
project activity has been implemented, the baseline will be calculated ex post by using the production figures and the
emission factors for the single strength juice and concentrate respectively
Baseline emissions = Coal used in the baseline (as per annex 2) * emission factor boilers
= 5 180 * 0.6*3.6
= 11,189 tonnes/annum
