As a member of the Leadership Council of Global Alliance for Clean Cookstoves (GACC), which was launched by the United Nations Foundation in 2010, Wang Shi is committed to promoting the implementation of the Clean Cookstove Project in China. In 2017, the C Team project team promoted the pilot use of clean cookstoves by 500 rural households in eight villages in Shaanxi Province to reduce the air pollution caused by unreasonable cookstove structure and insufficient combustion. In 2018, based on the Clean Cookstove Project, C Team launched the “Green Rural” plan, focusing on clean energy and community development in rural areas to make China's rural areas green and livable.
In order to better respond to the local needs for developing livelihoods and improving the community, C Team worked closely with Shaanxi Gender Development Solution and Bluetech Clean Air Alliance (BCAA) to jointly promote the Green Rural plan with the community-driven development approach, with support from Vanke Foundation and UNDP GEF SGP. Through community training and microfinance projects, it helped improve people’s wellbeing in Nangoumen Village. Joining hands with the rural environmental education program of the Sannong Society (Sannong: agriculture, farmers and rural areas) of Yan’an University, the project is committed to enhancing villagers’ environmental and health awareness so as to improve the village environment jointly with the villagers, and seeking more technical innovation and resources to support integrated applications of clean cooking and heating.
Green Rural Project
17 pilot households were selected in the heating season 2019-2020 for the demonstration and evaluation of three technologies, namely, photovoltaic power generation + water-heated bed structures, solar thermal + passive housing renovation, and biomass pellet fuel-adapted stoves . Another 5 coal-fired heating households served as control group.
The project team carried out a systematic assessment of the environmental effects of the demonstration technology.The assessment shows that all three technologies are effective in meeting the heating needs and engendering solid environmental benefits. According to calculations based on data collected from October 2019 to July 2020, the biomass stove option and the PV + water-heated bed structure option could reduce over 2,827.5 kg of pollutants and 96.2 tons of greenhouse gases; a total of 8,416 kWh of clean electricity was generated from mid-March to mid-September, when data were collected, generating an additional income of CNY3,198 for the residents. The clean heating technology options have served as coal substitutes, reduced the health and poisoning risks posed to residents by carbon monoxide, and improved their quality of life.
In the course of the project, the taskforce found it feasible to process locally sourced biomass raw materials, such as straw and discarded branches, into biomass fuel. They went on to incorporate the trial production of shaped biomass fuel to the pilot, and succeeded in producing biomass pellets, pioneering a path of producing shaped biomass fuel locally while providing a solution to the local straw pollution problem.
In rural areas of China’s northern Shaanxi province, villagers typically resort to tradition when it comes to heating their homes in winter. Such traditions rely on solid fuels (coal, fuel wood, etc.), resulting in a high level of indoor soot emissions and potential health hazards. Winter is a season with typically poor air circulation and little capacity for accommodating pollutants; compound this with the heating needs of northern China and part of the central-eastern territories, the efforts preventing and controlling air pollution are faced with stern challenges
