Renewable Transportation Alternatives:
Vehicles powered by renewable natural gas (RNG) and green fuels are helping to reduce greenhouse gas emissions, air pollution and dependence on petroleum-based fuels in California, across our nation, and around the world.
The California Renewable Transportation Alliance (CRTA) is working hard to get more trucks powered by RNG and renewable fuels deployed moving goods, transporting passengers and picking up refuse. Formerly known as the California Natural Gas Vehicle Coalition (CNGVC), CRTA works with decision-makers at every level of government to strategize on how best to meet the needs of all fleet types while supporting a robust fueling station network and spurring the development and use of renewable transportation alternatives.
