Abstract
We conducted a cost-benefit analysis of an air pollution abatement project that supplied energy efficient stoves in a residential sector of a ger area in Ulaanbaatar, Mongolia. It compared to some abatement options. The net present value of the abatement projects and the reduction of particulate matter PM10 and PM2.5 emissions during the investment timeframe were estimated. We also interviewed 50 households using the improved stoves to gather data on fuel consumption and other factors. Fuel consumption was estimated to decrease by about 30% as compared with traditional stoves. The project's net present value over the 15-year study period was estimated to be about US$133.81 million. The monetized health benefit through emission reductions was estimated to be more than 8.75 million US$/year over the same time period.
To test the impact of the improved stoves on indoor air quality, 24-hour monitoring of particulate matter (PM) and carbon monoxide (CO) was done in detached house and ger in ger area. The analyses focused on traditional stoves with raw coal, traditional stoves with semi-coke, improved stove type Silver mini, and Silver turbo with raw coal.
