Abstract: In order to analyze the environmental impact of global climate change resulting from Chinese boron industry, look for the way to economize energy and decrease pollution emission, carbon footprint resulting from pivotal technology was evaluated with the software of GaBi 4.4. The results showed that the borax production with boron concentrate brings the maximum total carbon footprint and the minimum is brought by the technology with boron-rich slag. Boron-rich slag is a good material to produce borax which can not only save boron resources but also reduce the environmental impact. Of all the boracic acid production technology, the salting out technology with paigeite ore brings the maximum total carbon footprint and the minimum is brought by the floatation technology with szaibelyite. Direct carbon footprint brought by two steps technology is least, but total carbon footprint is more. Reducing energy consumption especially coal is a good method to reduce the carbon footprint of the whole industry system.
