6.2.2 Methodology to quantify mitigation benefits through improved cookstoves

6.2.2 Methodology to quantify mitigation benefits through improved cookstoves This document provides a step-by-step methodology to quantify the mitigation potential of energy-saving cookstoves over a 10-year period. This approach is based on the Gold Standard, Technologies and Practices to displace Decentralized Thermal Energy Consumption (TPDDTEC) methodology. Parameters used in the (TPDDTEC) methodology11:

Part 1: Quantification of the mitigation potential of a single improved cooking stove over a 1-year period

The purpose of this part is to quantify the mitigation benefits (measured in avoided GHGs emissions) of one improved cooking stove using the following method and the provided excel sheet. Step 1: Determine the baseline scenario and quantify the emissions In this step the baseline scenario should be determined, i.e., what is the current method used for cooking and the respective values for the parameters mentioned about should be gathered. The emissions for the baseline scenario can be calculated as follows:

Step 2: Describe the mitigation technology and quantify the emissions In this step, the proposed technology and its mitigation potential need to be described. For example, how this new technology will improve energy and resources savings? Like the previous step, the emissions for the new scenario can be calculated using the following formula, while taking into account the changes caused by the

proposed, new technology (e.g., reduction of consumed firewood…). In this case, a reduction of 40 % of wood consumption is assumed.

Step 3: Quantify emissions reduction from the proposed technology compared to the baseline scenario

Finally, the emissions reduction for one improved cooking stove can be quantified using the formula above while taking into account the usage rate (Up,y parameter).

Part 2: Quantification of the mitigation potential of improved cooking stoves for 3400 households over a 4-year period

In this part, the yearly emissions reduction and the cumulated emissions reduction will be determined based on the results of the previous part and using the following assumptions and the provided excel sheet.

Assumptions

• Each household will get one improved cooking stove • In the first year 300 households will have access to the improved cooking stoves • In the second year 1000 additional households will have access to the improved cooking stoves • In the third year 1000 additional households will have access to the improved cooking stoves • In the last year all households will have access to the improved cooking stoves
