The National Football League says it plans to plant acres of trees in metropolitan Detroit.
It's aimed at off-setting carbon emissions caused by traffic generated by next year's Super Bowl.
NFL environmental director Jack Groh says he'll visit Detroit this spring to meet with the host committee, foresters and community groups.
The tree-planting is similar to what the NFL sponsored at this year's Super Bowl in Jacksonville, Florida.
The carbon-neutral project is the latest addition to the NFL's 13-year-old environmental campaign, which tailors its plans to each host city's needs.
