Comparison: State vs. Federal
• Rules. Before 2009, little action was taken at the federal level, beyond voluntary initiatives, to implement greenhouse gas (GHG) management strategies ensuring that GHG emissions are accounted for and controlled. However, the U.S. Environmental Protection Agency has changed its stance and is initiating actions to monitor and control GHG emissions.
Arizona has taken actions to address GHG emissions in order to meet state-established GHG emissions reduction targets. In addition, the state is working with other states to implement regional programs to monitor and control GHG emissions.
• Administration and enforcement. The Arizona Department of Environmental Quality's Air Quality Division administers the state's GHG management programs and coordinates with other states to assist in the implementation of regional GHG management initiatives.
