Founded in 1994, the Southern Colorado Clean Cities Coalition(SC4) is a grassroots non-profit organization dedicated to reducing the use of petroleum in transportation. SC4 provides educational events, networking opportunities, technical advice, business assistance, and education for policymakers on the benefits of domestic, renewable, and clean fuels. In 2015, SC4 helped fleets displace over 2.3 million gallons of gasoline and prevent more than 9,500 tons of greenhouse gas emissions into our atmosphere. We count on our membership base to support the organization and its activities. You can help by supporting our mission with an annual membership.
