This paper posits the conceptually useful allegory of a futuristic "World Climate Assembly" that votes on global carbon emissions via the basic principle of majority rule. Two variants are considered. One is to vote on a universal price (or tax) that is internationally harmonized, but the proceeds from which are domestically retained. The other is to vote on the overall quantity of total worldwide emissions, which are then distributed for free (via a pre-decided fractional subdivision formula) as individual allowance permits that are subsequently marketed in an international cap-and-trade system.
The authors consider the role of integrated assessment models in estimating the social cost of carbon—an estimation that is important in the formulation of U.S. climate policy.
Carbon taxes, which postpone extraction of fossil fuels and reduce cumulative carbon emissions, also have economic advantages over taxes on capital.
This discussion paper examines the potential role U.S. National Parks play in curbing greenhouse-gas (GHG) emissions through carbon sequestration—the process of moderating global climate change by removing carbon dioxide from the atmosphere and storing it in long-term mineral, organic, and oceanic reservoirs.

Nearly two decades of experience have shown that agricultural biotechnology has the potential to address some of the world’s pressing challenges. Its potential, however, cannot be addressed in isolation. Instead it should be part of a larger effort to expand the technological options needed to address persistent and emerging agricultural challenges.
The aim of this paper is to review the evidence on global trends in the application of agricultural biotechnology and identify some of their salient benefits. The paper is cognizant that biotechnology alone cannot solve the world’s agricultural challenges. But even though it is not a silver bullet, it should still be included in the package of technological options available to farmers. The evidence available today suggests that public policy should appeal more to pragmatism and less to ideology when seeking solutions to global agricultural challenges.

In 2012, when many energy experts argued that oil production had peaked, Leonardo Maugeri published “Oil: The Next Revolution,” which forecast a glut of oil and collapsing prices in the next several years. His prediction proved prescient. Now, as analysts look past today’s oil-market drama to a near future of robust liquefied natural gas exports, Maugeri is again challenging conventional wisdom. The long-hoped-for and hyped-up gas market, he concludes, will disappoint.
“Falling Short: A Reality Check for Global LNG Exports” details the new findings by Maugeri, a former oil industry executive who is now an associate with the Geopolitics of Energy project at Harvard Kennedy School’s Belfer Center for Science and International Affairs.

Improving end-use energy efficiency—that is, the energy-efficiency of individuals, households, and firms as they consume energy—is often cited as an important element in efforts to reduce greenhouse-gas (GHG) emissions. Arguments for improving energy efficiency usually rely on the idea that energy-efficient technologies will save end users money over time and thereby provide low-cost or no-cost options for reducing GHG emissions. However, some research suggests that energy-efficient technologies appear not to be adopted by consumers and businesses to the degree that would seem justified, even on a purely financial basis.
"Facilitating Linkage of Heterogeneous Regional, National, and Sub-National Climate Policies Through a Future International Agreement"
Linkage among emissions-reduction systems can reduce cost and advance equity, enhancing the chances for success of a new 2015 climate agreement.

The shale gas revolution has changed the landscape of American energy – transforming the US from a country that was building billion-dollar terminals along its coasts to import liquefied natural gas (LNG) from countries like Qatar, to one that is reconfiguring those facilities to export American natural gas as LNG around the world. Production of gas from shale has soared 1,200% over the past decade. In 2000, it accounted for only 1% of US natural gas production; by 2012, it was 39%. Many people in the American oil and gas industry will tell you that the unconventional boom is the most dramatic energy story they have witnessed in their careers. It has not only transformed the US energy picture, it has also encouraged a different perspective about the global supply picture.
