Their film ends with a comment affirming that global contraction budget limit to future emissions is '250 Billion Tonnes', if the 2 degree limit to global warming is to be held.

The group recognizes that emissions ‘contraction’ should be complete globally by 2050 if, once ‘feedback effects’ are included, we are to give better than 50:50 odds for keeping within the 2° rise. This is a critical, critical illumination of the scope of the world problem that threatens our existence: a total global emissions cap of 250 Gt C, accomplished by 2050.
The challenge to all of us is very simple, very clear, and the time is now.
