Join the Office of Sustainability & Environment (OSE) for a technical webinar at which OSE and SBW Consulting will share the draft greenhouse gas intensity targets under consideration and the analysis conducted to inform the targets. Presentations will be followed by the opportunity for comments and questions. OSE will also provide a brief overview of the proposed policy and the updated timeline.

This webinar is a follow-up to open houses in April and June that provided detailed background and the draft policy framework. Recordings and slides from those events are available at

This webinar will be recorded and posted on the OSE website afterwards.

About the Policy: Performance standards are a powerful tool to reduce climate pollution and transition toward cleaner, healthier buildings where we live and work. This policy is projected to reduce emissions from Seattle’s buildings (in total) 27% by 2050. This policy would gradually phase out carbon pollution from existing nonresidential and multifamily buildings over 20,000 sq. ft. through mandatory greenhouse gas (GHG) emissions targets beginning 2026 for the largest nonresidential buildings. Targets would become more stringent over time, to net-zero GHG emissions by 2050. Visit for more information and timeline.
