In the US, emissions from transport contribute over 30% of all carbon dioxide emissions, the major cause of climate change, and a significant fraction of other pollutants impacting local health. To address this problem, SEI developed an interactive website to help households identify how they can improve air quality and the publics’ health by modifying their individual travel choices.

GreenTrips helped individual households learn about opportunities they have for reducing their transport-related air emissions and thus contributing to a healthier city environment. The website used a straightforward question-and-answer format to prompt users for basic information about their use of cars and other modes of transport including buses, trains, and airplanes.

With this information, the website calculated how a household’s travel patterns lead to air pollution emissions and ultimately to environmental and public health impacts.
