Japan basically gives up on trying to reduce emissions

The world's fifth-largest greenhouse gas emitter, Japan once vowed to cut its emissions by a full 25 percent by 2020. But it's new government, facing a post-Fukushima country in which all nuclear plants have been shut down, has revised that number way down -- to just 3.8 percent. That's a small reduction from 2005 figures, but a three percent increase from emission levels in 1990.
