The lack of significant efforts at the national level to reduce greenhouse gas emissions (GHGs) in the United States has provided the impetus for a number of state programs. This article assesses the efficiency of these programs in making real progress in GHG reductions. It also explores the effect of state programs on the eventual adoption of a strong national GHG mitigation policy. While state programs are likely to demonstrate the viability of new mitigation approaches, they are also likely to create a set of expectations and precedents that will make a strong and coherent national policy more difficult.

Fifty-five percent of Georgia's developed coastline has been armored with various types of erosion protection devices. This article is about beach improvement projects at Jekyll Island that would operate under (a) a nourishment policy or (b) a retreat policy. Benefits are calculated from an intensive, on-site survey of beach visitors and the costs are calculated from observable sources. Two financing methods are considered: general revenue and user fee financing. The analyses imply recommending beach improvement as an effective policy within the considered time frame.
