US climate policy is unfolding under the Clean Air Act. Mobile source and construction permitting regulations are in place. Most important, EPA and the states will determine the form and stringency of the regulations for power plants. Various approaches would create an implicit price on emitting...

This paper outlines recent developments in U.S. climate policies. Although the United States does not participate in the Kyoto Mechanism, a number of climate policies are being implemented at state level as well as at the federal level. First, we report and compare the federal cap and trade...

The Clean Power Plan (CPP) is the centerpiece of the US efforts to reduce carbon emissions, introducing regulation of greenhouse gas emissions from existing power plants for the first time on a national basis. These regulations may interact with existing initiatives, for example, in California,...

We analyze policies to promote renewable sources of electricity. A renewable portfolio standard raises electricity prices and primarily reduces gas-fired generation. A “knee” of the cost curve exists between 15% and 20% goals for 2020 in our central case, and higher natural gas prices lower...

The EPA will issue rules regulating greenhouse gas (GHG) emissions from existing steam boilers and refineries in 2012. A crucial issue affecting the scope and cost of emissions reductions will be the potential introduction of flexibility in compliance, including averaging across groups of...

No colons in abstract

EPA is in the process of regulating U.S. greenhouse gas (GHG) emissions using its powers under the Clean Air Act. The likely next phase of this regulatory program is performance standards under Section 111 of the act for coal plants and petroleum refineries, which the agency has committed to...

Current and proposed greenhouse gas cap-and-trade systems allow regulated entities to offset abatement requirements by paying unregulated entities to abate. These offsets from unregulated entities are believed to contain system costs and stabilize allowance prices. However, the supply of offsets...

Emission offsets within cap-and-trade systems are widely believed to contain system costs and stabilize allowance prices. However, trends in offsets supply are uncertain, may be persistent, and may be correlated with other sources of uncertainty. In a dynamic stochastic model we find total costs...
