Indicative simplified baline and monitoring methodologies for lected small-scale CDM project activity categories TYPE III - OTHER PROJECT ACTIVITIES Project participants shall take into account the general guidance to the methodologies, information on additionality, abbreviations and general guidance on leakage provided at cdm.unfccc.int/methodologies/SSCmethodologies/approved.html. III.AD. Emission reductions in hydraulic lime production Technology/Measure 1. This project category compris alternative hydraulic lime production for construction purpos by blending a certain amount of conventional hydraulic lime with alternative material and additives. Production of hydraulic lime in the traditional manufacturing process requires more energy in comparison to the alternative lime process, since the addition of alternative material and additives reduces the amount of calcined material needed to develop the same properties per unit of final product. 2. The project activity takes into account only emission reductions associated with the reduced energy consumption by incread level of blending. Decread chemical relea of carbon dioxide during calcination process is not taken into account. Other measures such as energy efficiency improvements should be considered as a parate projec
t and may apply under Type II categories. 3. The following definitions apply: (a) (b) Hydraulic lime: commercial product for construction purpos, obtained through the hydration of calcined limestone; Alternative hydraulic lime: commercial product obtained through blending of a certain amount of hydraulic lime with alternative material and additive, showing similar properties and same applications as the conventional hydraulic lime; Alternative material: non-calcined mineral components comprising limestone and/or other inert materials obtained from a quarry. Examples of non-calcined mineral components include certain types of limestone, dolomite and marbles; Additive: solid or liquid material added to the blended product in small quantities, (less or equal to 0.05 tonne-additive/ tonne alternative hydraulic lime) which notably change its properties.

4. This methodology is only applicable if the rvice level of alternative hydraulic lime is the same or better than the hydraulic lime, i.e. the product obtained during the crediting period shall meet or exceed relevant properties of typical commercial hydraulic lime for construction purpos/applications, measured in accordance with an applicable or related standard1.

In ca where a national standard for testing hydraulic lime quality does not exist, an international standard or standard from another country shall be ud as a reference (e.g., International Lime Association).

6. It shall be demonstrated in the PDD that there is no other allocation or u for the amount of alternative material ud by the project activity, and there is enough availability of it during the crediti
ng period. If alternative material is purchad from other quarry owners, the procedure described in paragraph 3 of AMS-III.V may be ud. 7. This methodology is only applicable to a project activity implemented in an existing plant. It shall be demonstrated that the alternative hydraulic lime was not produced in that plant for at least the previous three years. 8. This methodology is limited to domestically sold output of the project activity plant and excludes export of alternative hydraulic lime. 9. Adequate data are available on baline hydraulic lime application in the market and relevant quality standards per application. 10. In order to exclude double counting, CERs can only be claimed by the producer of alternative hydraulic lime. 11. This methodology is not applicable if local regulations require the u of propod technologies for the manufacturing of alternative hydraulic lime. 12. Measures are limited to tho that result in emission reductions of less than or equal to 60 ktCO2 equivalent annually. Project Boundary 13. The project boundary includes all physical, geographical sites where: (a) (b) Alternative hydraulic lime is produced; Transportation of alternative material is conducted.我的优点作文
