Climate change presents unprecedented challenges for biological conservation. Agencies are increasingly looking to modeled projections of species’ distributions under future climates to inform management strategies. As government scientists with a responsibility to communicate the best available science to our policy colleagues, we question whether current modeling approaches and outputs are practically useful. Here, we synthesize conceptual problems with species distribution models (SDMs) associated with interspecific interactions, dispersal, ecological equilibria and time lags, evolution, and the sampling of niche space. Although projected SDMs have undoubtedly been critical in alerting us to the magnitude of climate change impacts, we conclude... |

We consider an empirical estimation of the Environmental Kuznets Curve (EKC) for carbon dioxide and sulphur, with a focus on confidence set estimation of the tipping point. Various econometric – parametric and nonparametric – methods are considered, reflecting the implications of persistence, endogeneity, the necessity of breaking down our panel regionally, and the small number of countries within each panel. In particular, we propose an inference method that corrects for potential weak-identification of the tipping point. Weak identification may occur if the true EKC is linear while a quadratic income term is nevertheless imposed into the estimated equation. Relevant literature to date confirms that non-linearity of the EKC is indeed not granted, which... |

Project-based mechanisms for emissions reductions credits, like the Clean Development Mechanism, pose important challenges for policy design because of several inherent characteristics. Participation is voluntary. Evaluating reductions requires assigning a baseline for a counterfactual that cannot be measured. Some investments have both economic and environmental benefits and might occur anyway. Uncertainty surrounds both emissions and investment returns. Parties to the project are likely to have more information than the certifying authority. The certifying agent is limited in its ability to design a contract that would reveal investment intentions. As a result, rules for baseline determination may be systematically biased to overallocate, and they also... |

Cities are not affected by global climate policy and the Kyoto Protocol - however many of them engage in voluntary activities. This paper analyses how communities in general and especially the city of Hamburg can contribute to global climate protection in their citypartnerships according to the slogan "think global, act local". Possible activities are in the fields of awareness-raising, capacity-building, exchange of experiences and joint project implementation. A focus is layed on projects according to the Clean Development Mechanism of the Kyoto Protocol in north-south citypartnerships. There is a clear potential for reduction of transaction costs in this kind of projects due to the institutional links of the citypartnership. For Hamburg, CDM-potential... |

We give empirical welfare results for global greenhouse gas emission control, using the first multiparty model to combine tax-versus-trading under uncertainties with revenue recycling. Including multiple parties greatly reduces the welfare advantage of an emissions tax over emissions (permit) trading in handling abatement-cost uncertainties, from that shown by existing, single-party literature. But a tax has a different, much bigger advantage, from better handling uncertainties in business-as-usual emissions. Either mechanism's free emissions share, from tax thresholds or free permits, which lowers its possible welfare gain from revenue recycling, may however dominate any tax-versus-trading advantage. Moreover, political and practical constraints, such as... |

Current policy discussions are making a very clear connection between domestic climate policies and international trade. In this article, the economic, legal and implementation issues relating to border tax adjustments for climate policies are discussed. The overall conclusion drawn is that the connection between trade and the environment is not new, having been discussed in considerable detail since the early 1990s, and reflected in an extensive economics literature. In addition, the legal aspects of border tax adjustments are not particularly new, although only a WTO ruling on their use in the presence of domestic climate policies will resolve any legal uncertainty about their use. However, there are some new issues concerning the determination and... |
