Our aim in this paper is to describe an opportunity for physics students and faculty to learn about an environmental issue of much current interest: the quantification, or footprint analysis, of carbon dioxide (CO2) and reactive nitrogen emissions. These can originate from human activities such as energy use, food consumption, and transportation, and are among the greenhouse gases (GHG) that contribute to global warming and rising sea levels. Moreover, nitrogen compounds also have effects on the chemistry and biology of the environment. Analyzing both of these footprints together captures multiple environmental impacts from the local to the global levels and can suggest mitigation strategies. We focus on the experiences of interdisciplinary teams, which included physics students and faculty, and that used the leading greenhouse gas analysis platform SIMAP (Sustainability Indicator Management and Analysis Platform).
