From: Analogical environmental cost assessment of silicon flows used in solar panels by the US and China
Environmental impact of metallurgical and solar grade of silicon production in the US and China between 2010 and 2030. (a) greenhouse gas emissions in tonnes; (b) carbon dioxide (CO2) emission in tonnes; (c) other pollution in tonnes. Pollution includes Particulate organic carbon (POC), black carbon (BC), nitrous oxide (N2O), methane (CH4), sulfur oxides (SOx), particulate matter with sizes smaller than 2.5 µm (PM2.5), airborne particulate matter with sizes smaller than 10 µm (PM10), nitrogen oxides (NOx), carbon monoxide (CO), and volatile organic compounds (VOC). Data are available in Supplementary Information (#4).
