The Geoengineering Project is an AEI project where experts study proposals to counter global climate change through geoengineering. It seeks to explore questions concerning how geoengineering options may affect national and international climate policy. In the Project's first phase, it will focus on approaches that aim to offset the warming effects of greenhouse gases by slightly increasing the amount of sunlight that the Earth's atmosphere reflects back into space.

Many uncertainties surrounding geoengineering center on the concept's economic and political aspects. The Geoengineering Project seeks to generate rigorous policy research exploring these economic and political questions. Among other issues, the Project will pay close regard to questions about how geoengineering may mesh with other strategies for coping with climate change (or how it may clash with them).

The Project commissions leading scholars to research some of the central issues of political economy raised by the concept of geoengineering. Separate papers will describe the results of each of these research efforts. AEI hosted a conference based on each of the research papers. These events are designed to bring the Project's research results to the attention of key representatives of government, academia, the news media, industry, and non-governmental organizations.
