Negotiations over carbon emissions resemble the end of a Quentin Tarantino film, when everyone has a gun pointed at everyone else and no one can make a move. Rich nations (like the U.S.) need to make the first cuts, but they won't until developing nations (like China) do and vice versa. Researchers from Princeton University suggest working on the individual level instead. It's the well-off people of the world in Indiana or India who are responsible for most carbon emissions. A strategy focused on rich individuals instead of rich countries might just get us out of this.
