Long-term greenhouse gas emission reductions – what's possible, what's necessary?

In: Energy Policy (2006) 34: 971-974


Climate is changing (WMO 2003) and there is increasing evidence that this is due to human activity (IPCC 2001). One way to react is to reduce greenhouse gas emissions into the atmosphere. Though this approach generally does not cause much objection, disagreements do occur when concrete emission targets are to be set. Against this background, the following article provides an arithmetic approach for the determination of long-term emission targets where the US and the EU are studied as examples.
