Time Warner Cable is ratcheting up its emissions-reduction initiative for its service fleet by setting a goal of lowering greenhouse gas emissions by at least 30 percent by the end of 2016.

The cable provider beat its past two-year goal of a 15-percent reduction with a 38-percent reduction announced earlier this year as part of the company's "Go Green" initiative.

"TWC had great results in our previous goal to reduce carbon intensity so we've doubled our goal to 30 percent for 2015 through 2016," said David Flessas, senior vice president of network operations and executive lead of the Go Green initiative. "TWC is committed to making a positive impact on our environment and will continue to raise awareness about sustainability and environmental issues. We're excited about the new goal and look forward to bolstering our efforts in the green space."

TWC is working toward the goal by replacing older fleet vans and trucks with more fuel efficient models. Earlier this month, the company purchased 540 of Ford's 2015 F-150 pickup trucks powered by the 2.7-liter EcoBoost with stop-start technology. In July, TWC added nearly 500 diesel Transit vans expected to increase mpg by 47 percent over gasoline-powered vans.

So far, the company has reduced its carbon intensity by 38 percent over two years, which exceeded a goal set in 2012 of a 15-percent reduction. The company achieved a 14.7 percent increase in fuel efficiency from 2012 in its fleet by purchasing more fuel efficient vehicles, the company announced in March. The company counts almost 20,000 vehicles in its fleet.
