Outdoor footwear and apparel operator Timberland has reported a 27% decrease in greenhouse gas emissions since 2006, as part of its green commitments.

However, Timberland said in its 2007-2008 Corporate Social Responsibility Report that it did not meet its 2008 renewable energy use goal of 22%.

The company's carbon footprint fell from 23,037 metric tons in 2007 to 18,781 in 2008, and Timberland is targetting a carbon footprint of 6,400 by 2015.

Its percentage of footwear production in "high risk" factories was also down - from 34% in 2007 to 1% last year.

Timberland president and CEO Jeffrey Swartz said: "During the last two years, we've had many successes, such as reducing our greenhouse gas emissions by 27%, nearly eliminating "high risk" issues in our footwear factories from sourcing channels and exceeding our targets for using organic cotton in apparel.

"But we've also encountered some challenges, such as being unable to completely eliminate PVC from our footwear or engage our employees in more community service. Our pursuit of sustainability drives us to use our influence to create positive change, and we're still seeking results."
