In celebration of Earth Day, Yahoo! announced the launch of a “Free Is Good” campaign aimed at motivating its online community of more than 500 users worldwide to reduce their impact on the environment through reuse.

From April 20 through May 4, Yahoo! will help inspire people to join groups and recycle by placing eco-friendly prizes, such as a “Smart car”, eco-trips and green cleaning services, in randomly selected reuse groups. Yahoo! created a microsite to make it easy for users to find a reuse group in their community. The site will be promoted on Yahoo!’s homepage and throughout the network. Yahoo! will also host reuse events at many of its campuses worldwide for employees.

Yahoo! is teaming up with reuse groups like Freecycle, a grassroots community of 4.7 million members across 85 countries, and other popular online reuse groups, to inspire people around the world to think twice before throwing an item in a landfill. In addition to helping our planet, reusing helps people save money and give back to their community.

“Through Yahoo! Green, our Carbon Neutrality program and other green initiatives, Yahoo! is committed to empowering the largest online community in the world with the tools, tips and information to make a positive impact on the planet,” said David Filo, co-founder and Chief Yahoo!. “We’ve seen a grassroots surge in consumers looking for information about reuse so we’re using our network to help move consumers from awareness to action.”
