Santa Monica, CA Contribution Analysis : Understanding GHG Inventory and Employee Commute Program Trends

City of Santa Monica, CA was a steering committee city in the Department of Energy funded research project on the contribution analysis – a new tool to help local governments understand their greenhouse gas inventory trends. The contribution analysis found that improved vehicle fuel economy, reduced commercial natural gas and electricity usage, and a cleaner electricity grid were the major drivers for emissions reductions. As part of the project, City of Santa Monica’s employee commute program trends were also analyzed. The analysis indicated that employee mode split and incentive effectiveness is less dependent on the quantity of strategies used by an employers and more about the quality of the strategy or the culture at the organization, or demographics of the employees at different businesses
