Here, we investigate the contribution of residential emissions to regional air pollution in highly polluted eastern China during the heating season, and find that dramatic improvements in air quality would also result from reduction in residential emissions. We use the Weather Research and Forecasting model coupled with Chemistry to evaluate potential residential emission controls in Beijing and in the Beijing, Tianjin, and Hebei (BTH) region. In January and February 2010, relative to the base case, eliminating residential emissions in Beijing reduced daily average surface PM2.5 (particulate mater with aerodynamic diameter equal or smaller than 2.5 micrometer) concentrations by 14 ± 7 μg·m-3 (22 ± 6% of a baseline concentration of 67 ± 41 μg·m-3; mean ± SD). Eliminating residential emissions in the BTH region reduced concentrations by 28 ± 19 μg·m-3 (40 ± 9% of 67 ± 41 μg·m-3), 44 ± 27 μg·m-3 (43 ± 10% of 99 ± 54 μg·m-3), and 25 ± 14 μg·m-3 (35 ± 8% of 70 ± 35 μg·m-3) in Beijing, Tianjin, and Hebei provinces, respectively. Annually, elimination of residential sources in the BTH region reduced emissions of primary PM2.5 by 32%, compared with 5%, 6%, and 58% achieved by eliminating emissions from the transportation, power, and industry sectors, respectively. We also find air quality in Beijing would benefit substantially from reductions in residential emissions from regional controls in Tianjin and Hebei, indicating the value of policies at the regional level. date: 2016 date_type: published publisher: National Academy of Sciences id_number: 10.1073/pnas.1604537113 creators_browse_id: 185 creators_browse_id: 159 full_text_status: public publication: Proceedings of the National Academy of Sciences volume: 113 number: 28 pagerange: 7756-7761 refereed: TRUE issn: 0027-8424 projects: Public health impacts in URban environments of Greenhouse gas Emissions reduction strategies (PURGE, FP7 265325) coversheets_dirty: FALSE fp7_project: yes fp7_project_id: info:eu-repo/grantAgreement/EC/FP7/265325/EU/Public health impacts in URban environments of Greenhouse gas Emissions reduction strategies/PURGE fp7_type: info:eu-repo/semantics/article access_rights: info:eu-repo/semantics/openAccess citation: Liu, J. , Mauzerall, D.L., Chen, Q., Zhang, Q., Song, Y., Peng, W., Klimont, Z.
