The dissertation introduces the Climate Boxes Framework, which provides a structure to discuss and improve alignment between policy positions and climate goals. The framework is used to explore the differences in mitigation paths implied by four different mitigation goals ("boxes"): 1) delaying climate change, 2) avoiding a global temperature increase of 1.5-2°C above pre-industrial levels, 3) avoiding a global temperature increase of 3-4°C above pre-industrial levels, or 4) no delay or avoidance of climate change. Throughout the dissertation, the focus is on identifying the physical and technical constraints that set the bounds on the climate goals that can be achieved via different types of mitigation. Overall, the work demonstrates that whether policies are consistent with "addressing climate change" depends materially on which mitigation goal is being pursued; most policy choices are only consistent with a subset of the boxes.

Parallel Pursuit of Near-Term and Long-Term Climate Mitigation Science, October 23, 2009
This piece summarizes my analysis of the contributors (pollutants & activities) to climate forcing over a 20-year period and concludes that two distinct treaties are needed to separately address the mitigation of long-lived versus short- and medium-lived pollutants.
This poster summarizes the main results of my master's research, including the finding that >65% of near-term (20-year) incremental radiative forcing will be caused by non-CO2 pollutants such as black carbon, methane, and tropospheric ozone. The poster also covers sources, measurability, and policy implications. The leading policy recommendation is for aggressive reduction policies for non-CO2 sources that are separate and complementary to an aggressive CO2 reduction policy.
Climate Change & the Developing World Guest lecture, April 2009 Haas School of Business, UGBA 196
Lecture illustrates bountiful entrepreneurial opportunities for both mitigation and adaptation in BRIC (Brazil, Russia, India, China) and developing countries. Pages 27 and beyond include data analysis on the emission sources of the five pollutants most relevant for climate (carbon dioxide, black carbon, methane, tropospheric ozone, sulfur dioxide), by nation/region and by activity.
Gas-CAP is an analytic tool to evaluate the global impact of national or sectoral CO2 emissions decisions, and the goal in its development was to create a bridge between more complex scientific models and the dynamic scenario planning needs of policymakers.The tool enables the user to set a global CO2 emission and atmospheric concentration target and then develop national or sectoral trajectories consistent with that target.
