"The Intergovernmental Panel on Climate Change (IPCC) has proven its value as an institution for large-scale scientific collaboration to synthesize and assess large volumes of climate research for use by policy-makers, as well as for establishing credibility of findings among diverse national governments. But the IPCC has received considerable criticism of both its substance and process."
"The Optimal Energy Mix in Power Generation and the Contribution from Natural Gas in Reducing Carbon Emissions to 2030 and Beyond—Summary"
This paper analyses a set of new scenarios for energy markets in Europe to evaluate the consistency of economic incentives and climate objectives. It focuses in particular on the role of natural gas across a range of climate policy scenarios (including the Copenhagen Pledges and the EU Roadmap) to identify whether current trend and policies are leading to an economically efficient and, at the same time, climate friendly, energy mix.
"The Optimal Energy Mix in Power Generation and the Contribution from Natural Gas in Reducing Carbon Emissions to 2030 and Beyond"
The authors evaluate the consistency of economic incentives and climate objectives in Europe, with regard to energy markets. In this context, they examine policy interactions between the EU-ETS and Europe's renewable target—and the role of natural gas in a transition to a low-carbon economy.
"A successful international climate policy framework will have to meet two conditions, build a coalition of countries that is potentially effective and give each member country sufficient incentives to join and remain in this coalition. Such coalition should be capable of delivering ambitious emission reduction even if some countries do not take mitigation action. In addition, it should meet the target without exceedingly high mitigation costs and deliver a net benefit to member countries as a whole. The novel contribution of this paper is mostly methodological, but it also adds a better qualification of well-known results that are policy relevant."
"Modeling Economic Impacts of Alternative International Climate Policy Architectures: A Quantitative and Comparative Assessment of Architectures for Agreement—Summary"
With broad recognition that a coordinated global effort is needed to address climate change, negotiations are already underway to define a new international climate agreement. Various architectures for such an agreement have been proposed. This paper undertakes a first-of-its-kind comparison of some prominent options using a common framework to assess four features of these architectures: economic efficiency; environmental effectiveness; distributional implications; and political acceptability, as measured in terms of feasibility and enforceability. The aim is to derive useful policy insights for designing a post-Kyoto agreement.
"Modeling Economic Impacts of Alternative International Climate Policy Architectures: A Quantitative and Comparative Assessment of Architectures for Agreement"
This paper provides a quantitative comparison of the main architectures for an agreement on climate policy. Possible successors to the Kyoto protocol are assessed according to four criteria: economic efficiency; environmental effectiveness; distributional implications; and their political acceptability which is measured in terms of feasibility and enforceability. The ultimate aim is to derive useful information for designing a future agreement on climate change control.
