The outcome of the December 2011 United Nations climate negotiations in Durban, South Africa, provides an important new opportunity to move toward an international climate policy architecture that is capable of delivering broad international participation and significant global CO2 emissions...

The view that intergenerational distributive justice and efficiency should be treated separately is familiar, yet controversial. This article elaborates the often-implicit justifications for separate treatment and provides a more express statement of how and when such treatment is appropriate....

California's Global Warming Solutions Act of 2006 limits California's greenhouse gas (GHG) emissions in 2020 to their 1990 level. Global climate change is a pressing environmental problem, and the best possible public policies will be required to address it. Therefore, analyses of prospective...

In a paper presented to the Royal Meteorological Society, Brodie (1905) presented a data series that presaged the modern Environmental Kuznets Curve: in the decades leading up to 1890, the number of foggy days in London rose steadily, but after 1891, the fogs began to subside. Brodie attributed...

Understanding and minimizing the transaction costs of policy implementation are critical for reducing tropical forest losses. As the international community prepares to launch REDD+, a global initiative to reduce greenhouse gas emissions from tropical deforestation, policymakers need to pay...

The introduction of the U.S. SO2 allowance-trading program to address the threat of acid rain as part of the Clean Air Act Amendments of 1990 is a landmark event in the history of environmental regulation. The program was a great success by almost all measures. This paper, which draws upon a...

This paper develops a simple model of a polluting industry and an innovating firm. The polluting industry is faced with regulation and costly abatement. Regulation may be taxes or marketable permits. The innovating firm invests in R&D and develops technologies which reduce the cost of pollution...

Global climate change mitigation will require the development and diffusion of a large number and variety of new technologies. How will patent protection affect this process? In this paper we first review the evidence on the role of patents for innovation and international technology transfer in...

This paper examines the effect of environmental policies on technological innovation in the specific case of renewable energy. The analysis is conducted using patent data on a panel of 25 countries over the period 1978-2003. It is found that public policy plays a significant role in determining...

Countries who adopted regulation of coal-fired power plants after 1980 generally did so at a much lower level of per-capita income than did early adopters -- poor countries regulated sooner. This phenomenon suggests that pioneering adopters of environmental regulation provide an advantage to...
