Number: RL34272 Title: State Greenhouse Gas Emissions: Comparison and Analysis Authors: Jonathan L. Ramseur, Resources, Science, and Industry Division Abstract: A variety of efforts that seek to address climate change are currently underway or being developed on the international, national, and sub-national level (e.g., individual state actions or regional partnerships). These efforts cover a wide spectrum, from research initiatives to GHG emission reduction regimes. If Congress establishes a federal program to manage or reduce GHG emissions, the emission requirements would likely impact different states differently. However, predicting the different impacts of policies is a complicated task, because multiple factors play a role. Such factors include alternative design elements of a GHG emissions reduction program, the availability and relative cost of mitigation options, and the regulated entities' abilities to pass compliance costs on to consumers.
