Climate Data & Planning

Seattle is a recognized leader in climate action and we will continue to pursue bold strategies that demonstrate how a low-carbon city is also a prosperous, healthy, and vibrant city.

Climate Planning & Executive Orders

The City of Seattle is already working on many solutions needed to reduce our climate impact. Now is the time to accelerate our climate work and deepen investments in historically underserved communities who will face disproportionate climate impacts. 

On Earth Day 2025, Mayor Harrell issued an Executive Order (EO) for Seattle to develop a modernized One Seattle Climate Action Plan focused on climate resilience and adaptation, building a green economy, and protecting public health, as well as near-term actions to reduce transportation emissions.

Mayor Durkan issued an Executive Order in 2021 directing departments to implement new carbon-based building performance standards, expand transit access and Healthy Streets, and advance clean energy workforce development.

The Seattle Department of Transportation released the first-ever Climate Change Response Framework (CCRF), a vision for reducing transportation emissions and making it easier for Seattleites to choose more efficient, shared, and sustainable travel options.

Mayor Durkan issued an Executive Order in 2020 to advance a Green New Deal for Seattle, work collaboratively and boldly to eliminate climate pollution, prioritize climate justice, and invest in an equitable transition to a clean energy economy. 

Climate Data & Reporting

Seattle implements data-driven policies and programs designed to have the greatest impact in equitably reducing our city's Greenhouse Gas (GHG) emissions, which are gasses that are released into the atmosphere primarily as a result of human activities.

The more GHGs we release, the more our climate is impacted. We measure our greenhouse gas emissions using emissions inventories to better understand the scope and scale of our local climate footprint, the impact of our actions, opportunities for progress, and the challenges ahead. 

Seattle tracks, measures, and reports our GHG emissions across transportation, buildings, and waste sectors every two years. 

The One Seattle Climate Portal is a publicly available map-based website that houses more frequent and granular data indicators of emissions in Seattle. 

The City of Seattle has developed a consumption-based emissions inventory (CBEI) which estimates emissions associated with all the goods and services consumed within the community, no matter where they are produced (including the extraction of raw materials, manufacturing, and global transportation). This inventory looks at all of the emissions associated with the food we eat, the things we buy, how we travel, and the homes we live in.
