The Wall Street Journal cites research by Civil and Environmental Engineering Assistant Professor Chris Cherry in an article about cutting carbon. The article discusses the United Nations’ 17th annual climate-change conference next month in Durban, South Africa, with the purpose of sealing a new carbon-cutting deal to succeed the soon-to-expire 1997 Kyoto Protocol. The article ticks through carbon cutting technologies and their potential pitfalls. In doing so, it cites Cherry’s research on solar power, which finds that manufacturing the necessary lead batteries threatens to release more than 2.4 million tons of lead pollution by 2022, or one-third of today’s total global lead production.
