Based at Princeton University, the Carbon Mitigation Initiative (CMI) is an independent academic research program sponsored by BP and administered by the Princeton Environmental Institute (PEI). CMI is Princeton’s largest and most long-term industry-university relationship. Established in 2000, the mission of CMI is to lead the way to a compelling and sustainable solution to the carbon and climate change problem.

 


Participants

CMI currently includes 17 lead faculty investigators and over 60 research staff and students. The program brings together scientists, engineers, and policy experts to investigate the dual challenge of supplying the energy that the world needs without emitting greenhouse gases that change the climate. Since its inception, CMI has been committed to the dissemination of its research findings so they may benefit the larger scientific community, government, industry, and the general public.

 


New Initiatives

One of the unique characteristics of the CMI is that it continually readjusts its programming based upon new scientific discoveries, technological advances, and changing political landscapes. Over the past two years, CMI launched three new initiatives.

Methane: Methane is the second most important anthropogenic climate forcer after carbon dioxide. Efforts to decipher current trends and assess future methane emissions necessitate accurate accounting of different methane sources and sinks, as well as a clear understanding of their variability across temporal and spatial scales. These remain fundamental challenges for the scientific community. Since 2017, CMI has supported three complementary projects that address the largest unknowns in methane cycling. They include research on wetland methane emissions and the development of two global-scale modeling projects aimed at quantifying the individual sources, sinks, and variations of methane associated with land and atmosphere.

Soil Carbon: Soils are the largest pool of carbon near the Earth’s surface, roughly as large as the atmosphere, biosphere, and surface-ocean combined. Each year, soils take up more carbon than they emit. Because of the imbalance between soil carbon uptake and emissions, soils presently act as a net carbon sink absorbing roughly 20% of anthropogenic CO2 emissions. Recent studies reveal that a key predictor of soil carbon storage is the abundance of certain fine-grained minerals. A primary goal of this project is to decipher the fundamental mechanisms that cause this correlation in order to inform new soil carbon sequestration approaches.

Infrastructure: To meet the 2°C target of the Paris Agreement, global greenhouse gas emissions would have to decline from their current value of over 50 billion metric tons of CO2 equivalents per year, to net- zero sometime between the middle and the end of this century. The U.S. would need to meet a similar, if not more stringent, target. Many deep decarbonization scenarios for the U.S. have been proposed, but these have paid little attention to constraints related to rates of deployment. Thus CMI is initiating a large project on net-zero greenhouse gas-emitting infrastructure for the U.S.

The purpose of the project is to describe qualitatively and quantitatively the engineering/industrial activities and financial flows associated with one or more infrastructure plans that have the potential to deeply decarbonize the U.S. economy by mid-century. Organized by CMI, this is a joint effort involving several other University entities and external collaborators.
