Sammamish Climate Challenge

*The Climate Challenge Pilot Program was sunsetted in Jan 2025. Please visit the Carbon Footprint Calculator for household carbon emissions information.*

The City of Sammamish is proud to announce the Sammamish Climate Challenge Pilot Program. Sammamish is a vibrant, growing community with quality neighborhoods, diverse natural features, and outstanding recreational opportunities. The City is in the final stages of developing a Climate Action Plan with strategies and actions to reduce greenhouse gas emissions and vehicle miles traveled. You can join this challenge and contribute to a cleaner, healthier future!

This platform makes it easy and fun for community members to reduce their environmental impact. Users can select from various green actions and track their progress while engaging in friendly competition with neighbors. Actions are simple everyday things you can do to reduce your impact and save you money. As actions are completed, the Climate Challenge will calculate household carbon reductions, cost savings, and other metrics using data specific to Sammamish and our region.

The Sammamish Climate Challenge was initiated in tandem with the development of the Climate Action Plan. While the CAP has not yet been adopted, the overarching goals were set by City Council direction in March 2023 and include:

• Achieving greenhouse gas (GHG) reduction targets that reduce sources of GHG emission by at least 50% by 2023, 75% by 2040, and 96% by 2050, compared to a 2019 baseline.
• Achieving a per capita Vehicle Miles Traveled (VMT) reduction by 30% by 2030, and 50% by 2050, compared to a 2016 baseline.

Help Sammamish reach our goals! The City is aiming for 250 households to sign up for the Climate Challenge by the end of 2024.
