In recent years, the air quality of Ulaanbaatar has deteriorated and, during winter months, the city now ranks amongst the most polluted cities globally. In spite of continued efforts to improve the air quality, continual migration to Ulaanbaatar has caused the problem to worsen. Much of the population growth has been in the city’s low-income ger1 (Mongolian national dwelling) districts, where coal, wood, and hazardous non-conventional fuels, such as household waste, are burned for heat. This has led to significant increases in the capital city’s air pollution emissions. Previous efforts to improve the city’s air quality have focused on stove-switching and the subsidized sale of 144,000 efficient stoves to residents of the ger district.2 While these programs had initial success, issues with stove breakage, continued migration to the city, and 40 percent of the stoves distributed being resold outside of the city have combined to undermine their initial impact. In May 2018, a team from the CCAC led by UN Environment (UNEP) and the Frankfurt School of Finance and Management (FS), travelled to Ulaanbaatar to meet with XacBank, a Mongolian Commercial Bank, to investigate the feasibility of setting up a household, end-user finance facility to assist ger residents in the purchase of cleaner household heating alternatives in order to replace the inefficient traditional heat stoves that are presently used in the gers. The CCAC team met with a range of stakeholders, including ger residents, local and national government, academics, engineers, and technology suppliers, in order to assess the available technological solutions and make an assessment of those that are appropriate for households in the Ulaanbaatar ger districts. To evaluate which technologies are appropriate in this context, it was necessary to consider a number of factors, as described in the following sections. POLICY Since the 1990s, various measures have been implemented by the government in an attempt to reduce the severity of air pollution in Ulaanbaatar, often targeted at improving cooking and heat stoves for households in the ger districts. Following the 2016 Parliamentary elections, the newly formed Government of Mongolia (led by the Mongolian People’s Party) developed the National Action Plan for Reducing Air and Environmental Pollution. The plan contains measures designed to tackle Ulaanbaatar’s air pollution problem. Implementation of the following steps is particularly relevant: ◼ a 50–100 percent discount for off-peak electricity consumption for ger district households ◼ a gradual prohibition of the use of raw coal for household heating ◼ the expansion of the electricity distribution network and sub-stations in the ger district ◼ the development of standards for household electrical heaters ◼ tax exemptions for domestic products with advanced and environmentally friendly technology 1. The ger is the traditional Mongolian domicile and consists of a wooden frame and a layering of different ‘blankets.’ 2. The World Bank Clean Air Project successfully disseminated 40,830 efficient stoves, and the MCC project sold a total of 103,255 subsidized stoves. Financing Household Clean Energy Solutions iii ◼ the development of regulations to incentivize citizens and businesses in the area to miti- gate environmental pollution, reduce heat loss, and improve energy efficiency. ENERGY SITUATION During winter months, temperatures in Ulaanbaatar regularly fall to –20°C, so keeping warm becomes a fundamental aspect of survival. A range of stoves are used in the households of the ger districts. The traditional stoves are constructed from cast iron and have poor thermal properties, retaining heat for a maximum of three hours after firing, and producing up to 20 times
