SEI worked with the City’s Office of Sustainability and Environment to define what “carbon neutrality” might mean for a community and then to develop alternative scenarios for how Seattle might attain such an ambitious goal.

The work involved developing baseline forecasts of Seattle’s emissions growth out to 2050, exploring alternative definitions of carbon neutrality, assessing the relative spheres of influence of city government and other community stakeholders, and developing deep reduction scenarios. The modeling for this analysis was accomplished through LEAP.
