Seattle Sounders announce plans to go carbon-neutral starting with 2019 season

The Seattle Sounders have announced a commitment to become carbon neutral by making no net contribution to carbon dioxide in the earth's atmosphere.

The Sounders worked with the Seattle firm Sustainable Business Consulting to calculate the organization's greenhouse gas emissions and develop a plan to eliminate those sources in the 2019 season and thereafter.

For sources that can't be eliminated, like team travel, the Sounders will work to offset emissions in cooperation with Forterra, a nonprofit organization dedicated to sustainability.

"We're incredibly excited to announce that our club is officially carbon neutral," said Sounders owner Adrian Hanauer. "The Sounders have always been committed to investing in our community, and that includes recognizing the immense responsibility we have as environmental stewards.

"Sustainability is a key pillar of our club and this new step is a logical extension of the efforts we have already had in place.

The Sounders will host a tree-planting event on Feb. 24 in Burien, Washington, to kick off the program and begin the 2019 MLS regular season at home against expansion FC Cincinnati on March 2.
