Black carbon particulate matter emissions affect public health and contribute to climate change. Black carbon emissions are also short-lived climate forcers, and limiting these emissions has a potential to influence the pace of global warming. The majority of aircraft black carbon emissions occur at cruise, and a lack of emission measurements has impeded the development of inventories and quantification of impacts. To bridge this gap, Project 41 synthesized measurements of black carbon emissions at cruise and other relevant experimental data, and assessed methods of mapping ground emissions to estimates of cruise emissions.

OUTCOME

Synthesis of black carbon measurements as related to estimating cruise black carbon emissions.
