 What's being built is the world's largest liquefied natural gas terminal. It's been given the green light by the Federal Energy Regulatory Commission. It has not yet been approved by the Department of Energy. The massive project, known as CP2, would be built in Cameron Parish, Louisiana. It would be able to export up to 20 million metric tons of LNG per year. It would be connected to a large natural gas pipeline that would transport natural gas from Texas. Environmental groups, meanwhile, have expressed concerns about the project.
