The Lone Star Clean Fuels Alliance in Austin, Texas this week celebrated 20 years of being green, starting before being green was cool.

The LSCFA recognized the achievements of many leaders who helped Austin cut 10 tons of greenhouse gas emissions in one year alone, and attendees had the opportunity to drive renewable energy vehicles such as the Nissan Leaf and a stand-up electric police mobility vehicle.

The LSCFA, formerly known as Central Texas Clean Cities, is a non-profit coalition dedicated to reducing petroleum consumption through alternative fuels. Over the past 20 years the association has helped to clean up City of Austin fleet vehicles as well as other fleet and personal vehicles in five Central Texas counties counties. In 2012 alone, its stakeholders reduced petroleum consumption by 1.6 million gallons. Clean Cities helps to advance the alternative or renewable fuels of propane, biofuels: ethanol/E85 and biodiesel, natural gas, electric and hydrogen. It was the sixth Clean Cities coalition started in the U.S. where there are now about 90.
