Buildings are one of the largest and fastest growing sources of climate pollution in Seattle, responsible for more than one-third of our greenhouse gas emissions. These emissions pollute our air, accelerate climate change, and harm people’s health and the environment, disproportionately impacting communities of color and people with lower incomes. Many U.S. cities, including Seattle, are developing Building Performance Standards (BPS) that set long term targets on climate-polluting emissions from buildings. To help building owners get started, the City of Seattle’s Office of Sustainability & Environment has developed new case studies, most of which include cost estimates. View the case studies here.
