Since launching in 2007, the Lexus Eco Challenge has inspired and empowered more than 8,500 middle and high school students to learn about the environment and take a stand to improve it. From educating the community about the benefits of solar ovens to producing bio-fuel from used fast food oil, students across the country have tackled a wide range of topics and issues. Students are once again invited to participate in the third annual Lexus Eco Challenge for a chance to win part of $500,000 in grants and scholarships.
