Pachauri said,"It is not enough to set any aspirational goal for 2050, it is critically important that we bring about a commitment to reduce emissions effectively by 2020."
Reinforcing the point he added, if the G8 commitment to keep global temperature rise to 2°C is to be met that global emissions must peak by 2015.Few National 2020 Targets Even Come Remotely Close
That's a bit earlier than is sometimes mentioned and really drives home the need to be setting short term goals based on science rather than political expediency. Unfortunately, with a few exceptions (Norway, Japan), this message seems to have been lost on national leaders.
The general consensus among scientists is that in industrialized nations emissions must be reduced about 25-40% below 1990 levels by 2020 to put the planet on track to keep temperature rise to a minimum and avoid catastrophic climate change. Think that's a tough thing to do? Check out how Lester Brown thinks we can reduce emissions 80% by 2020.
