In terms of environmental protection, we have been committed to the recycling of renewable aluminum resources for 38 years, and promoted the research and application of lightweight aluminum alloys in the manufacturing of automobiles and rail transit products by replacing steel and copper with aluminum. We have been making efforts to protect environment as a major action to fulfill our social responsibilities. We are capable of analyzing and managing low carbon emissions in the whole life cycle of aluminum alloy and aluminum alloy products. We have a wide range of renewable aluminum recovery channels and are capable of massively producing and utilizing renewable aluminum resources. For every ton of renewable aluminum we have recycled, we can reduce CO and SO emissions by about 11 tons, save electricity by about 13,000 kWh, reduce ore mining by about 11 tons, discharge solid waste by about 20 tons and reduce water consumption by 22 cubic meters. In 2021, we will save 6.3 billion kWh of electricity, 5 million tons of ore mining and 10 million cubic meters of water, and reduce 5 million tons of CO and SO emissions and 9 million tons of solid waste emissions to contribute to the realization of carbon peaking and carbon neutrality in China.
