The Regional Greenhouse Gas Initiative (RGGI) is an effort by nine Northeast and Mid-Atlantic states to develop a regional, mandatory, market-based cap-and-trade program to reduce greenhouse gas (GHG) emissions from the electricity sector. The initiative is expected to lead to an increase in the...

The SO2 trading program has achieved reductions in emissions ahead of schedule, with allowance prices below the marginal costs that were anticipated for the program. This paper explores the experience with the program and proposes a taxonomy of reasons why allowance prices are low. The...

Title IV of the 1990 Clean Air Act Amendments (CAAA) established a market for transferable sulfur dioxide (SO2) emission allowances among electric utilities. This market offers firms facing high marginal abatement costs the opportunity to purchase the right to emit SO2 from firms with lower...

The 1990 U.S. Clean Air Act Amendments (CAAA) instituted a national program in tradable sulfur dioxide (SO2) emission permits, referred to as "emission allowances," in the U.S. electricity sector. This paper provides a survey and assessment of the SO2 allowance trading program with a focus on...

We experimentally study auctions versus grandfathering in the initial assignment of pollution permits that can be traded in a secondary spot market. Low and high emitters compete for permits in the auction, whereas permits are assigned for free under grandfathering. In theory, trading in the...

When it was launched in 2005, the European Union emissions trading system (EU ETS) was projected to have prices of around €30/ton CO2 and to be a cornerstone of the EU’s climate policy. The reality was a cascade of falling prices, a ballooning privately held emissions bank, and a decade of...

We use a stochastic dynamic framework to compare price collars (price ceilings and floors) in a cap-and-trade system with uncertainty in the level of baseline emissions and costs. We consider soft collars, which provide limited volume of additional emission allowances (a reserve) at the price...

The U.S. Environmental Protection Agency's (EPA) proposed greenhouse gas (GHG) performance standards for power plants are an important step forward in regulating GHGs in terms of both their substantive impact and legal precedent. Nevertheless, we have some concerns with the proposal, which we...

California will implement a cap-and-trade program to limit emissions of carbon dioxide covering industry and electricity sector emissions in 2013, expanding to cover transportation and natural gas in 2015. Although cap-and-trade would increase annual electricity costs for the average customer by...

California will enact an economy wide cap-and-trade program on CO2. Estimates of the value of tradable emissions allowances in the first year range from roughly $2.6 to $7.8 billion, when electricity and industry are covered under the program. Those sectors receive most of their allowances for...
