For Daniela Chona ’20 and Pete Edmunds ’20, a summer spent as research assistants for one of their Yale SOM professors led to an unexpected role: as co-authors of a report tracking greenhouse gas (GHG) emissions, and efforts to curb them, among the biggest companies in the United States. The report, written with Professor Lesley Meng and published recently by the Yale Center for Business and the Environment, examines the varying standards for how companies report emissions, identifies the biggest emitters, and looks at company goals and initiatives for emissions reduction, among other insights. The report, titled The report grew out of frustration over lack of data on GHG emissions among top companies.
