Satisfying global demand for energy, food, and goods without emitting CO2 to the atmosphere is a central challenge of the 21st century.  My research is aimed at understanding the scale of that challenge and finding ways to meet it.
Future CO2 emissions and electricity generation from proposed coal-fired power plants in India
Earth's Future | April 25, 2017

With its growing population, industrializing economy, and large coal reserves, India represents a critical unknown in global projections of future CO2 emissions. As of mid-2016, proposed coal-fired power plants in India are incompatible with its NDC to reduce carbon intensity 33-35% by 2030.

Trade affects location of air pollution deaths
Nature | March 30, 2017

In a groundbreaking interdisciplinary analysis, we quantify the global links among consumption of goods and services, production of air pollution, atmospheric transport of that pollution, and human mortality due to the pollution. We find that roughly a quarter of air pollution deaths are related to goods produced in one world region for consumption in another.

Global carbon uptake by cement carbonation
Nature Geoscience | November 21, 2016

Globally, carbonating cement materials are a large, overlooked and growing sink of CO2, which has offset 43% of the total process CO2 emissions (excluding those from related fossil energy inputs) from production of cement between 1930 and 2013.

Carbon lock-in: Types, causes, and policy implications
Annual Review of Envt. and Resources | September 2, 2016

Existing technologies, institutions, and behavioral norms together constrain the rate and magnitude of carbon emissions reductions in the coming decades. We review recent research on "carbon lock-in," the implications for decarbonization efforts, and propose a research agenda that can help bridge the gaps between science, knowledge and policy-making.
