Urban density both facilitates consumption opportunities and encourages individuals to drive less and walk and use public transit more. Using several data sets, we document that high quality of life consumer center cities are low carbon cities. We discuss possible causal channels for this association.

This paper examines how carbon pricing would reduce emissions in the electricity sector. Both carbon prices and cheap natural gas reduce the historic cost advantage of coal plants. The shale revolution resulted in unprecedented variation in natural gas prices that we use to estimate the potential near-term effects of carbon prices. Estimates imply that a price of $20 ($70) per ton of CO2 would reduce emissions by 5 (10) percent. Carbon prices are most effective at reducing emissions when natural gas prices are low, but have negligible effects when gas prices are at levels seen prior to the shale revolution.

I measure the industry impacts of an environmental tax reform where a carbon tax is used to finance full or partial corporate tax integration. I find that the industry impacts of such a reform are likely to be modest (in the sense of impacts on returns on equity).

On March 11, 2008 the University of Virginia Faculty Senate voted in favor of having the university take steps to make it climate neutral. This paper examines whether such a policy is feasible, and further whether pursuing a policy of climate neutrality is likely the best way to spend university resources, if the goal is to reduce the university’s carbon footprint. A revised version of this paper was published as Going Green: The inconvenient truth about U.Va.\'s carbon neutrality initiative; Virginia Policy Review (Vol. 2, No. 1) September-October 2008.

Stringent regulation for mitigating greenhouse gas emissions will impose different costs across geographical regions. Low-carbon, environmentalist states, such as California, would bear less of the incidence of such regulation than high-carbon Midwestern states. Such anticipated costs are likely to influence Congressional voting patterns. This paper uses several geographical data sets to document that conservative, poor areas have higher per-capita carbon emissions than liberal, richer areas. Representatives from such areas are shown to have much lower probabilities of voting in favor of anti-carbon legislation. In the 111th Congress, the Energy and Commerce Committee consists of members who represent high carbon districts. These geographical facts suggest that the Obama Administration and the Waxman Committee will face distributional challenges in building a majority voting coalition in favor of internalizing the carbon externality.

Abstract This paper provides model-based estimates of the value of oil in Alaska's Arctic National Wildlife Refuge (ANWR). The best estimate of economically recoverable oil in the federal portion of ANWR is 7.06 billion barrels of oil, a quantity roughly equal to US consumption in 2005. The oil is worth $374 billion ($2005), but would cost $123 billion to extract and bring to market. The difference, $251 billion, would generate social benefits through industry rents of $90 billion as well as state and federal tax revenues of $37 billion and $124 billion, respectively. A contribution of the paper is the decomposition of the benefits between industry rents and tax revenue for a range of price and quantity scenarios. But drilling and development in ANWR would also bring about environmental costs. These costs would consist largely of lost nonuse values for the protected status of ANWR's natural environment. Rather than estimate these costs and conduct a benefit–cost analysis, we calculate the costs that would generate a breakeven result. We find that the average breakeven willingness to accept compensation to allow drilling in ANWR ranges from $582 to $1782 per person, with a mean estimate of $1141.

In economic, technical and political terms, the security of energy supply is of the utmost importance for Europe. Alongside competition and sustainability, supply security represents a cornerstone of the EU’s energy policy, and in times of rising geopolitical conflict plays an increasingly important role in its external relations. Within this context, the contributors analyse and explore the natural gas, nuclear, and hydrogen energy sectors, which will be of critical significance for the future of energy supplies in Europe.

Greater use of renewable energy is seen as a key component of any move to combat climate change, and is being aggressively promoted as such by the new U.S. administration and by other governments. Yet there is little economic analysis of renewable energy. This paper surveys what is written and adds to it. The conclusion is that the main renewables face a major problem because of their intermittency (the wind doesn't always blow nor the sun always shine) and that this has not been adequately factored into discussions of their potential. Without new storage technologies that can overcome this intermittency, much of the decarbonization of the economy will have to come from nuclear, carbon capture and storage (CCS) and energy efficiency (geothermal and biofuels can make small contributions). Nuclear and CCS are not without their problems. New energy storage technologies could greatly increase the role of renewables, but none are currently in sight.

Cap and trade systems are emerging as the front-running policy choice to address climate change concerns in many countries. One of the apparent attractions of this approach is the ability to achieve hard limits on emissions over a control period. The cost of achieving this certainty on emission limits is price volatility. I discuss and evaluate various approaches within cap and trade systems to reduce price volatility. A fundamental trade-off exists between certainty of emission limits and price volatility. A pure carbon tax sacrifices certainty of emission limits in favor of price stability. I discuss how a hybrid carbon tax can be designed to achieve a balance between price stability and emissions certainty. This hybrid, dubbed the Responsive Emissions Autonomous Carbon Tax (REACT), combines the short-run price stability of a carbon tax with the long-run certainty of emission reductions over a control period.
