"...[T]he Copenhagen Accord is "only" a political agreement, so it does not provide sufficient assurance that countries will take action. But how much difference does it make that the Copenhagen Accord is a political rather than a legal agreement? Obviously, political agreements do not require domestic ratification, so they provide a weaker signal of domestic commitment. But the legal versus non-legal form of an instrument makes less of a difference in other respects, such as judicial enforcement, since even when an agreement is legally-binding, there are relatively few opportunities for adjudication either internationally or domestically. And evidence from other regimes suggests that states often take non-binding agreements quite seriously and make significant efforts to implement them."

Oil security and the threat of climate disruption have focused attention on the transportation sector, which consumes 70% of the oil used in the United States.
This study explores several policy scenarios for reducing oil imports and greenhouse gas emissions from transportation.

The finance of climate mitigation and adaptation in developing countries represents a key challenge in the negotiations on a post-2012 international climate agreement. Finance mechanisms are important because stabilizing the climate will require significant emissions reductions in both the developed and the developing worlds, and therefore large-scale investments in energy infrastructure. The current state of climate finance has been criticized for its insufficient scale, relatively low share of private-sector investment, and insufficient institutional framework. This policy brief presents options for improving and expanding climate finance.

International climate negotiations are at an impasse because the world's two largest greenhouse gas (GHG) emitters, the United States and China, are unwilling to accept binding emission-reduction commitments. At the same time, each blames the other for its inaction. This paper proposes a global "deal" for breaking the deadlock in a way that reconciles both countries' economic concerns with the imperative of reducing emissions. The deal has two core elements: (1) All major emitting countries agree to reduce GHG emissions by implementing significant, mutually agreeable, domestic policies and (2) The largest industrialized-country emitters agree to establish a global Carbon Mitigation Fund that would finance the incremental cost of adopting low-carbon technologies in developing countries.

Our proposal for a post-2012 international global climate policy agreement contains three essential elements: meaningful involvement by key industrialized and developing nations; an emphasis on an extended time path of targets; and inclusion of market-based policy instruments. This architecture is consistent with fundamental aspects of the science, economics, and politics of global climate change.
