Protect Our Planet

Sounders FC was the first carbon neutral professional soccer team in North America and the first carbon neutral pro sports team in the United States. We commit to measuring, offsetting, and work towards reducing our footprint every year. We will collaborate with partners to educate youth most affected by environmental justice in King County and empower them to improve community health outcomes.


Sounders FC works in collaboration with Seattle-based Sustainable Business Consulting to calculate its Greenhouse Gas emissions and identify opportunities to reduce our impacts wherever possible.

Sounders FC partner with Forterra to offset 100% of the carbon emissions we are not able to reduce ourselves. Our team, staff, and fans plant trees in our local RAVE Foundation communities to help improve the air and water quality where we live, work and play.

While we cannot reduce our team’s air travel, we continue to work aggressively to lower our environmental impact integrating sustainable behavior in our Font Office through our cross-departmental Green Team. Our Green Team’s ongoing efforts include installing compost bins at our Front Office and team training facilities, educating our organization on energy and waste reduction, and influencing commuting habits.

Carbon Footprint Calculator

You know the club calculates and offsets its’ carbon emissions every year, but did you know you could also calculate your carbon footprint as an individual?  Use this carbon footprint calculator to see what it would take offset your individual emissions!



 1. What is a Carbon Offset?

An Offset reduces, avoids, or sequesters the equivalent of one ton of CO2e in one place to “offset” of an equal amount of CO2e somewhere else in the world. Sounders FC is purchasing carbon offsets to offset those greenhouse gas (GHG) emissions that it cannot reduce internally. It is purchasing enough offsets to account for 100% of its carbon emissions.  

Benefits of this type of financial support

  • Allows Sounders FC to lower its climate impact beyond what can currently be achieved through internal efforts
  • Funds emissions reduction projects in our local community by planting trees that will sequester carbon and help clean the water and air in Puget Sound, while keeping the money here locally with a community non-profit. 
 2. Why did we choose Forterra as our Offset provider?

We chose Forterra for a few reasons. Their mission is aligned with Sounders FC sustainability goals as their mission is to secure land for a sustainable future.

Forterra’s Evergreen Carbon Capture Program helps area companies and households take positive action on the climate crisis by offsetting their carbon emissions through tree-planting.

They are the leading provider here in the Puget Sound for carbon offset projects. Sounders FC will actually be able to put trees into the ground that will sequester enough carbon to fully offset all of our emissions and clean up the air and water in the Puget Sound, while supporting a local non-profit that will put money into the pockets of local people, and offer us a project where our staff, team, fans, and partners can participate.

 3. What type of Offset project did we select?

The Green-Duwamish River provides important ecological, social, and economic resources for people in and around King County, WA. The River flows over 93 miles from the Cascade Mountain range to Elliott Bay, through the traditional territories of the Muckleshoot, Squamish, Duwamish, Upper Puyallup, and Puget Sound Salish peoples. The River provides critical habitat for endangered Puget Sound Chinook salmon1 as well as three other species of salmon. It has also been identified as the 4th most threatened river in the United States by American Rivers. High water temperatures are one of the main issues affecting Chinook salmon populations, especially in the Green Duwamish River watershed, primarily from lack of trees and shrubs and the shade they provide. High water temperatures affect salmon health in all life stages and sends ripple effects throughout the watershed, including decreased health and food supply for Orca whales and other wildlife. One of the main actions to support Chinook populations is to “keep streams shaded.” Planting and maintaining trees and shrubs in priority planting areas along the riparian corridor will provide shade and protect cool water as well as create habitat for native fish, pollinators, and other wildlife. Intact riparian corridors also provide significant ecosystem services for local communities, such as reduction of heat and air pollution and filtration of stormwater. 

 4. What percent of our investment goes to the Offsets as opposed to an administration fee?

Sourcing, administering, maintaining and verifying projects costs money. The amount that Sounders FC pays covers this and the offsets, with these administrative costs in line or lower than what most non-profits take as overhead for charitable donations.

 5. Don't offsets just allow us to keep polluting and not make the tough decisions that we will eventually need to make?

No. Sounders FC has been and will continue to make strides to reduce its own operational emissions. We view offsets as an intermediate step. We shall first look to reduce where we can, and for those areas where we presently cannot, use offsets as part of our overall strategy for lowering our environmental impact.

 6. How do we know these offset projects are ocurring?

Sounders FC had the ability to choose the specific projects we wanted to support and will actually be able to put the trees in the ground themselves. Forterra will keep track of the trees throughout their growth to make sure they don’t die and continue to sequester the carbon they are designed to do.

 7. Is it just greenwashing?

Greenwashing is a term used to describe a false or exaggerated claim, where a company tries to make itself sound better than it is performing. Sounders FC is not doing this as we are being transparent about how this is an intermediate step while we identify how we can directly reduce our emissions.

 8. Are we doing this just to look good on Earth Day?

No. Sounders FC has made a leadership commitment not only in MLS, but in the local and global sports scene by becoming the first professional soccer team in North America to become carbon neutral, and one of less than five teams in the world.

 9. Why is Sounders FC offsetting instead of directly participating in global reduction agreements like COP21?

Sounders FC has been and continues to find solutions for efficiency and conservation across the globe, but the path to emissions reductions is long and we do not have direct control over all emissions sources (MLS schedule, air travel plans related to tournaments, league matches, Concacaf matches, US Open Cup, etc.). While we work towards the direct reductions needed, Sounders FC has identified offsets as the best interim course of action.

 10. Can I offset my individual emissions from my home, commute and personal travel?

We leave this decision up to each individual. Sounders FC shall not be offsetting employees’ personal offsets. If you are interested, there are several websites and offset providers that provide this service.
