We focus on the effects of international policy on low-carbon investment decisions in the private sector. Carbon markets, corporate investment, and energy technology innovation are key elements of this inquiry.

This research investigates the reasons that firms chose to undertake (or not) CDM projects that would generate carbon income. Current research focuses on the sugar and cement industries in each country. Research method involves field data collection and interviews of firm managers and carbon market partipants. Future research possibilities include expanding sectoral scope (e.g. steel, fertilizer) or country coverage (e.g. South Africa, Indonesia, Turkey, South Korea, China).

Climate policy is likely moving toward a regime of parallel domestic policies that are coordinated and reported internationally. Because of the complexity of this new interaction, understanding investment decisions in response to both domestic and international policies will be a key to establishing a successful and sufficiently ambitious long-term international approach to transitioning to a low-carbon economy. This research and teaching agenda will probe the motivations for emerging economy firms to invest and innovate in low-carbon technology. The central research question of this proposal is: How do firms in emerging economies respond to international and domestic energy policies when making low-carbon investment decisions? The research will evaluate the differences in deployment and international policy participation in solar photovoltaic and wind electricity generation in India, Brazil, South Africa, and South Korea. Through field research and interviews, the investigators will assess the major policy influences for low-carbon investment decisions in these countries and technologies. This work will contribute to scholarship on firm decisionmaking in response to energy policies. It can also potentially inform the approach of national and international low-carbon technology policy. Through courses and research experience, this proposal encourages students to link technology outcomes with policy drivers; to develop an informed, comparative international perspective on technology investments; and to engage with this important policy discourse in the US and internationally.

This research investigates large-scale, decadal transitions to bioenergy and nuclear power in Sweden, Brazil, and the United States, through expert interviews and surveys. The goal is to establish the factors seen by participants as the most important for energy transitions.
