| Political attention has increasingly focused on limiting warming to 2°C. However, to date the only mitigation commitments accompanying this target are the so-called Copenhagen pledges, and these pledges appear to be inconsistent with the 2°C objective. Diverging opinions on whether this inconsistency can or should be resolved have been expressed. This paper clarifies the alternative assumptions underlying these diverging view points and explicits their implications. It first gives simple visualizations of the challenge posed by the 2°C target. It then proposes a “decision tree”, linking different beliefs on climate change, the achievability of different policies, and current international policy dynamics to various options to move forward on climate change. |

| Although a global cap-and-trade system is seen by many researchers as the most cost-efficient solution to reduce greenhouse gas emissions, developing countries governments refuse to enter into such a system in the short term. Hence, many scholars and stakeholders, including the European Commission, have proposed various types of commitments for developing countries that appear less stringent, such as sectoral approaches. In this paper, we assess such a sectoral approach for developing countries. More precisely, we simulate two policy scenarios in which developed countries continue with Kyoto-type absolute commitments, whereas developing countries adopt an emission trading system limited to electricity generation and linked to developed countries'... |
