There is a difference. It is important when quoting the report to keep this distinction in mind. In his report Garnaut refers to parts per million CO2 equivalent, not parts per million CO2.

One thing about being an elected official once 95-99 you see inside the machine of governance a bit, enough to see that there are quite a few things politicians can’t fix, so they talk, wring hands, talk more, call a meeting, issue a statement, travel to another meeting, and so on and even convince themselves officiously that they are doing something. We are in that space.
