Prior to Copenhagen, we published The 350 Emergency Pathway, a technical brief designed to help movement and policy activists understand the implications of extremely stringent emissions-reduction targets. Such targets are now a major part of the debate, but are poorly understood — neither their associated trajectories nor their political implications have been well explored.
The brief was extremely well received. The folks at 350.org printed many copies, and distributed it to bother their network activists and developing country negotiators. It was debated and then adopted as part of a core position by Climate Action Network Latin America. And it was a major input into a high-profile scientists statement — The Copenhagen Prognosis — that was released at COP15.
